Thermometric titration
This document discusses thermometric titration, where the endpoint of a titration reaction is determined by measuring the temperature change. Key points:
- Titrant is added continuously and the temperature change is measured, with the endpoint identified by an inflection point on the temperature curve.
- The temperature change observed is directly related to the enthalpy change of the reaction.
- Factors like heat losses, temperature differences between titrant and analyte, and stirring must be controlled for accurate results.
- Automated systems use burets for precise titrant addition, a thermistor probe for temperature measurement, and software for data collection and endpoint determination.
- Parameters like mixing, probe placement,
core cleaning by soxhlete extractor
1. The experiment aims to clean core plugs obtained from a reservoir of hydrocarbons using a Soxhlet extraction apparatus to extract oil and calculate porosity.
2. A Soxhlet extraction involves boiling toluene in a flask, with its vapors condensing and extracting oil from the core plugs in a thimble. The process repeats through cycles of filling, soaking, and draining until the solvent runs clear.
3. The experiment involves placing core plugs in a thimble, extracting with toluene for a minimum of 7 cycles or until the plugs are clean, then drying and weighing the plugs to calculate effective porosity after hydrocarbon removal.
Electron cloud model
In the 1920s, Louis de Broglie, Erwin Schrödinger, and Werner Heisenberg developed the electron cloud model of the atom. De Broglie proposed that electrons have wave-like properties, while Heisenberg established that the exact location and momentum of a particle cannot be known simultaneously. Schrödinger then created mathematical equations to predict the probability of finding electrons in certain regions or orbitals, rather than fixed orbits. This led to the concept of an electron cloud showing the probable locations of electrons around the nucleus.

The technology provides flexibility to adapt to changing reservoir conditions over time.
FTIR Lab Report
1) FTIR was used to obtain spectra of organic solvents and oils to identify an unknown oil sample. PCA analysis was performed to reduce redundant data and produce PCA scores.
2) PCA plots of scores 1 vs 2 produced clear clusters for solvents and oils, allowing identification of the unknown oil as safflower oil. Key distinguishing wavenumber regions were below 1700 cm-1.
3) Higher wavenumber regions produced overlapping clusters, as solvents and oils shared common carbon-carbon bond features not distinguishable by FTIR.

Coulometry and Electrogravimetry
Coulometry and electrogravimetric analysis are analytical techniques that involve completely oxidizing or reducing an analyte through electrolysis. In coulometry, the quantity of electrical charge passed is measured and related to the amount of analyte present. In electrogravimetry, the analyte is converted electrolytically into a product that is weighed to determine the analyte amount. Both techniques are accurate and precise, but require ensuring all current passed results in analyte oxidation/reduction. Controlled-potential coulometry uses a constant potential, while controlled-current coulometry applies a constant current, each with their own experimental considerations to achieve complete analyte conversion.
Ammonia
Ammonia is produced industrially via the Haber-Bosch process. It involves reacting nitrogen gas and hydrogen gas at high pressures between 100-1000 atm and temperatures around 450°C with an iron catalyst. The process was developed in 1909 and allows ammonia to be synthesized from nitrogen in the air and hydrogen from methane. It is widely used to produce fertilizers and explosives. Other processes like the ICI process and Braun purifier process are also used but the Haber-Bosch process dominates due to its efficiency. Ammonia finds applications as a fertilizer, refrigerant, and in other industries.

Common analytical techniques include gravimetric, volumetric, spectroscopic, and electroanalytic methods. Fundamental equipment includes balances, volumetric glassware, ovens, desiccators, and filters.
Transport Of Oxygen 2
1) Hemoglobin is more efficient at transporting oxygen than suggested by its dissociation curve because the amount of oxygen it carries depends on both the partial pressure of oxygen and carbon dioxide.
2) At tissues with high carbon dioxide levels, hemoglobin has a lower affinity for oxygen and releases more oxygen, while at the lungs with low carbon dioxide it has a higher affinity and picks up more oxygen.
3) Fetal hemoglobin has a higher affinity for oxygen than adult hemoglobin due to its dissociation curve being shifted left, allowing it to more readily obtain oxygen from the mother's blood through the placenta.

The procedure involves connecting the helium porosimeter to a gas source, calibrating it, loading a rock sample, and using software to collect and analyze pressure and volume measurements to calculate porosity.
Official heart rate lab report
The experiment aimed to investigate how dancing and listening to music can affect heart rate. It was hypothesized that dancing would have a greater impact on heart rate than listening to rock music due to increased oxygen demands from body movement. The independent variable was activity (dancing or music), while the dependent variable was heart rate. Control variables included the test subject, room temperature, time of activities, music, and heart rate measurer. Results showed dancing increased average heart rate to 95 beats/minute compared to 87 beats/minute for music, supporting the hypothesis.

4) Contraindications and risks of exercise stress testing.
Experiment 1 & 2
The document discusses how heart rate, blood pressure, and other vital signs change with exercise and cold stimulus. It provides data on a subject's baseline vital signs, post-exercise vital signs, and heart rate during and after maximum exertion. The document analyzes the data, explaining how factors like increased stroke volume, withdrawal of vagal tone, and increased sympathetic tone lead to higher heart rates and blood pressures during exercise or stress. It also discusses how the autonomic nervous system and homeostatic mechanisms work to return vital signs to normal after exertion or stress.
Experiments
Experiment 1 measured changes in blood pressure and heart rate in response to cold stimulus. Applying ice to the foot caused systolic, diastolic, and mean arterial pressures to increase. Heart rate reached its maximum within 15 seconds then began to decrease but did not return to resting levels. Experiment 2 examined changes with exercise, finding increases in blood pressure and heart rate. Pulse pressure, the difference between systolic and diastolic pressures, also increased due to exercise primarily affecting systolic pressure. Recovery time provided information about physical fitness levels.
Homeostasis
Homeostasis refers to the body's ability to maintain stable internal conditions such as temperature and glucose levels. It is regulated by negative feedback mechanisms. For example, temperature receptors in the skin sense changes and send signals to the hypothalamus in the brain. If body temperature rises, the hypothalamus activates sweating and blood vessel dilation to cool the body through evaporation. Conversely, it triggers shivering and vessel constriction when temperatures fall to conserve heat. Various organs also help regulate variables through hormones, like the liver controlling glucose with insulin secretion. The skin plays an important role in homeostasis through insulation, sweating, and temperature reception.
Biology in Focus Chapter 5
The document provides an overview of cellular membranes and membrane transport. It discusses how membranes are fluid mosaics composed of phospholipids and proteins that allow selective permeability. Membranes regulate transport across cellular boundaries through passive diffusion down concentration gradients and facilitated transport using channel and carrier proteins. The plasma membrane separates the cell from its surroundings and exhibits selective permeability through these transport mechanisms.
Experiment 1 and 2
The document contains data tables and analysis of changes in vital signs (blood pressure, heart rate, etc.) in response to cold water immersion and exercise. Key findings include:
1) Cold water immersion caused increases in systolic/diastolic blood pressure, mean arterial pressure, and heart rate, preparing the body for "fight or flight."
2) Exercise similarly increased these vital signs. Cardiac output increased by 5,800 mL/min based on a stroke volume increase from 75 to 100 mL/beat and heart rate change.
3) Recovery heart rate returned to resting levels 20 seconds after reaching maximum, showing homeostasis mechanisms act more slowly than stress responses.

Scientific Report Writing Tips
1. The document discusses the importance and purpose of lab reports and scientific papers in communicating scientific research findings. These written reports allow information to be accessible over long periods of time.
2. Individual scientists perform experiments to test hypotheses, and present their findings in papers or reports to persuade others to accept or reject their hypotheses. If results stand up to criticism, they become accepted scientific knowledge.
3. A scientific report typically includes a title, abstract, introduction, materials and methods, results, discussion, and literature cited sections. The document provides guidance on writing each section effectively.

Write-ups are short reports on the lab exercise you performed. You willgive a short background
inEoducing the topic, give any corrections or changes in the procedures used, present your data and
d[scuss it. This format is similar to that used by all practicing biologists.
Diedions for the write-ups are specific and should be followed correctly. Your I teaching assistant will
dsuJss with you the content expected for each particular write up. General directions for the content and
furm of each section are given below. lf you have any questions on what to include, how to phrase
wnefting, how to cite it, etc., please see vour teachinq assistant before the write- up is due. They will go
oueryourwrite- up and give you suggestions on how to improve it. They will not, however, grade it or
gtue you a point total.
fuitg information. Your first best source of information is your textbook. Use the index to search for
Eymrds. Most of you will also use the internet. Be VERY careful. Anyone can post anything on the
cb-gDod or bad. The UT library has a guide that will help you decide located at
l*bfdilxuides.utoledo.edu/findinternet. How can you tell a page has good information or not? Apply the
CRAAP test! I encourage you to use sources other than Wikipedia. Wikipedia is a good place toptart but
most professors do not consider it a strong source for scientific references.
General. Write-ups are due the lab session following the completed lab. Write-ups are a maximum of
t*o (2) single - spaced or four (4) double-spaced typewritten or word processed pages. Handwritten
ass[nments will not be accepted. Lab write-ups must be prepared individuallv by each participant.
Goltaboration in data collection is fine, but not in the preparation of written work to be submitted for agr*. Each report will be graded based upon its completeness, accuracy, organization, and the overall
quahty of the work. Penalties of 10o/o per day will be assigned to write-ups received after the scheduled
deadline.
A handout will be given for each lab write up. Use it. The grading rubric used by the TA is based on the
handout. lf you adequately and correctly address each point on the handout, you will do well. The
handout is typically in the format of a bullet list to make it easy to use. Your lab write up MUST be in
essay format. Any report turned in using outline format will Nor be accepted.
Prcsentation. This is a science lab. You are evaluated on the scientific content in your write-up.
However, if your presentation is so poor that it impedes understanding, points will be deducted. General
rules of grammar and spelling must be followed. Use a spell- checking program or have someone proof
read your paper to increase accuracy. The campus has a Writing Center that can be very helpful in
reviewing your work and giving helpful advice. The style of writing may be somewhat different from that in
your composition classes. You are expected to be formal in your ...
Format for Research Papers California State Universit.docx
Format for Research Papers
California State University, Bakersfield
Department of Biology
A scientific research report is a form of
communication in which the investigator
succinctly presents and interprets data collected in
an investigation. Writing such reports is similar to
the writing in other scientific disciplines except
that the format will differ as will the criteria for
grading.
Writing the Report
The questions and hypotheses that initiate
an investigation, the resultant data gathered, and
the background information obtained by reading
the literature will lead to conclusions. Your
research report presents these conclusions and the
appropriate evidence (data and relevant literature).
Before writing the report, construct an
outline that logically presents the information to
support your conclusions. Organize the data into
tables and figures to present the evidence in a
logical order. Many authors prefer to construct a
draft by rapidly putting down ideas with little
regard to sentence structure, and to make
corrections later. Others prefer to make revisions
as they proceed. Write the report with a target
audience of other students with experience in
biology equivalent to that of the class for which
the report is written.
Proper use of English is considered
paramount in grading. Your major responsibility
is to make the reader understand exactly what you
mean by using words with precision, clarity, and
economy. Every sentence should be exact and say
something of importance (no "padding").
Economy and accuracy require using
straightforward English sentences (subject, verb,
and object). Follow a consistent pattern of tenses.
Write in the active voice unless you have good
reason to use the passive voice. The active is the
natural voice, the one in which people commonly
speak and write.
Quotations are to be avoided. All
sentences should be based on your understanding
of source material that you then write as your own
original sentences. When discussing the works of
others, do not include extraneous information,
such as first names or scientific affiliations. In
scientific writing, the major idea of a paragraph (or
sentence) is placed first. Evidence for the idea,
modifications, exceptions, etc., then follow. This
allows readers to quickly skim research reports by
reading the first sentence in each paragraph.
After finishing a draft, review it to see if
the paragraphs and sentences follow a logical
sequence. Examine the arrangement of paragraphs
within a section; some may belong in another
section. Make sure that the transitions from one
idea to another are clear. Study each sentence to
see if it can be clarified, shortened, or omitted.
Rewrite as necessary to achieve clarity. This type
of review and rewriting is best done after not
looking at the manuscript for a few days. Then,
you should ...

Writing a Formal Lab Report and Scientific Papers
General Tips o Be concise. In scientific writing, it is very important to say as much as is needed while using as few words as possible. Lab reports should be thorough, but repetition should be avoided. The entire report should be clear and straightforward.
· Write in the third person. Avoid using the words “I” or “we” when referring to the experimental procedure. For example, instead of “I boiled 50 mL of water for 10 minutes,” the report should read, “50 mL of water was boiled for 10 minutes.” This can be a bit difficult to get used to, so it is important to pay close attention to the wording in the report
· Use correct verb tenses. Many students become confused when trying to decide whether to use past or present tense in their reports. If referring to anything that happened in the past, then use the past tense. For example, if you are writing about an experiment you have already performed, then refer to it in the past tense. Present tense should be used when referring to a scientific principle, such as, “Water is two parts hydrogen and one part oxygen.” The general rules for verb tenses are as follows:
· The experimental procedure has already been conducted, so use the past tense of the verb when referring to it:
Ex: The purpose of the experiment was...
The compound was weighed to 5 g...
· The report, equipment, and theory still exist, so use the present tense of the verb for them:
Ex: The purpose of this report is...
Bunsen burners are used...

INSTRUCTIONS FOR THE PREPARATION OF A TECHNICAL ESSAY .docx
INSTRUCTIONS FOR THE PREPARATION OF A
TECHNICAL ESSAY
INTRODUCTION
The technical essay is a review paper that synthesizes and interprets work
on a particular subject area. Therefore, the format is not as standardized as that
of a research paper. By bringing together the most pertinent findings of
numerous papers from diverse journals, a review paper serves as a valuable
summary of research. In writing your essay, interpret the primary journal article
in a series of paragraphs that build on your discussion, giving particular attention
to the problem or topic posed in your introduction. In addition, relate your
findings to previous observations or experiments from the supplemental
references that you have chosen. Discuss briefly any logical implications of the
journal articles for practical application or future studies. A good review paper
not only synthesizes information; it also provides a critical overview of an
important scientific problem.
After you have finished your first draft of your essay, review the structure
of your manuscript. Are the sections arranged in logical sequence? After you
are satisfied with the structure of your essay manuscript, attend to the details:
the paragraphs, the sentences, and the words. Expect to do several drafts of
your paper before you are satisfied with the final product. Good writing is
generally the product of careful rewriting or revising in which you evaluate your
attempts at organizing and expressing your ideas. In the process you end up
scrutinizing the ideas themselves, as well as your own mastery of the subject.
CITING REFERENCE MATERIALS
The text of a biological paper usually contains numerous literature
citations, or references, to the published studies of other authors. This is
because scientists rarely work in a vacuum; hypotheses are developed, tested,
and evaluated in the context of what other scientists have written and discovered.
Thus, careful documentation, or acknowledgment of the work of others, is
essential to good scientific writing. Biologists also need to provide literature
citations because, like other writers, they have an ethical and legal obligation to
give credit to others for material that is not their own. Such material includes not
only direct quotations, but also findings or ideas that stem from the work of
someone else.
Unlike writers in the humanities and social sciences, biologists rarely use
footnotes or endnotes to acknowledge sources. Instead, they insert literature
citations directly in the text, either by giving the last name of the author(s) and the
year of publication (name-and-year method), or by referring to each source by a
number method. Such rules, even if they seem arbitrary, make the reporting of
2
references an orderly activity, minimizing confusion for writers, readers, editors,
and publishers.
In this course, the name-and-year method, also known as the Harvard
method,.

Central dogma
The central dogma of biology describes the flow of genetic information from DNA to RNA to protein. DNA provides the genetic code or blueprint that is transcribed into messenger RNA (mRNA), which is then translated into proteins. Specifically, the document discusses that DNA is transcribed into mRNA, which is then translated into proteins through codons on the mRNA that each represent an amino acid, with 64 possible codons to code for the 20 amino acids.
Central dogma
The central dogma of biology describes the flow of genetic information from DNA to RNA to protein. Originally, it was thought to be a simple linear process from DNA to mRNA to protein. However, it is now understood that there can be reverse transcription from RNA back to DNA, and proteins can influence other proteins through prion diseases. The genetic code is translated from RNA nucleotides in groups of three codons to specify the 20 amino acids used to build proteins.

Blackworm Lab Set Up
This document provides instructions for an experiment on controlling homeostasis and heart rate in blackworms. Students will use scalpels or scissors to trim transfer pipettes to more easily move blackworms between petri dishes and microscope slides. They will then remove the heads and tails of worms placed on depression slides under a microscope to count the pulse rate by focusing on a specific body segment and counting waves passing through. Chemicals will also be tested on worms to collect data on heart rate responses.
Crayfish lab set up
Crayfish are freshwater crustaceans related to lobsters that are characterized by a joined head and thorax and segmented body. They typically grow to about 3 inches long and are found worldwide, especially in the US. The lab is set up to measure the oxygen consumption (metabolism) of crayfish using a dissolved oxygen meter in an experimental chamber maintained at a constant temperature by a hot water bath. Large and small crayfish are kept in separate containers to compare their oxygen usage.
Plant pigments and photosynthesis
This lab involves two exercises. Exercise 1 involves separating plant pigments like carotene, xanthophyll, and chlorophyll a and b using paper chromatography and calculating their Rf values. Exercise 2 measures the rate of photosynthesis in isolated chloroplasts under different light conditions (intensity and wavelength) and temperatures (boiled vs unboiled chloroplasts) using the dye-reduction of DPIP, which changes color from blue to colorless when reduced during the light reactions of photosynthesis. Students will take absorbance readings at various time points to examine how the rate changes under different experimental conditions.
Flower fruit seed lab domb reworked 10.12
The document discusses plant reproduction and strategies for seed dispersal. It explains that flowers evolved to facilitate sexual reproduction in plants and allow plants to pass their genes to offspring. Various dispersal mechanisms are described, including wind dispersal for seeds with wings or plumes, water dispersal for buoyant seeds, and animal dispersal for seeds contained in fleshy fruits or attached to hooks/barbs. The mistletoe plant is highlighted as having evolved a mutualistic relationship with mistletoebirds, which eat the fruit but disperse intact seeds in their droppings, aiding the plant's dispersal.

This document contains a lab assignment on osmosis and diffusion involving potatoes placed in different sucrose solutions. The assignment asks students to create graphs of their results, compare their data to the class data, discuss potential sources of error, propose improvements to the experiment, explain how the graphs show which solutions were hypotonic and hypertonic, and predict the concentration of an isotonic sucrose solution. It provides rubrics for scoring each question.
Diffusion and osmosis student handout
1. Diffusion and osmosis are processes by which molecules and water move across selectively permeable membranes from areas of higher concentration to lower concentration. Diffusion is the random movement of all molecules, while osmosis specifically refers to the diffusion of water through a membrane.
2. Experiments were conducted using potato cores and onion cells to observe the effects of osmosis when placed in solutions of varying sucrose concentration. As sucrose concentration increased outside the cells, water would move out of the cells by osmosis. This loss of water caused the cells to lose turgor pressure and shrink or plasmolyze.
3. By calculating the water potential of the solutions using the formula Ψ = Ψ
Beta gal lab writeup
This document contains post-lab analysis questions for students to answer about 3 enzyme activity experiments measuring the effect of substrate concentration and temperature on enzyme activity. Students are asked to plot and analyze the data, comment on accuracy and precision, and predict and explain the shape of graphs for different experimental conditions. They are also asked questions about how the body regulates the enzyme amylase and digests starch.
A critical thinking framework for understanding excellence in biological thin...
This document discusses the importance of critical thinking in scientific understanding. It argues that our natural thought processes are biased and we must learn to think scientifically. Some key points made:
- Our thoughts are often biased by preconceptions, so science aims to minimize bias through critical methods.
- A critical approach to science focuses on understanding reasons and thinking through ideas, not just memorizing facts.
- Students must confront and modify their own preconceptions to truly understand scientific concepts.
- Scientific thinking involves continually questioning observations and testing hypotheses through experimentation, rather than following a set series of steps. Developing a scientific habit of mind is more important than finding the right answer.

Honors Biology Pre-Assessment for Modules 1 and 2
Evolution can explain both the unity and diversity of life through common descent from a shared ancestor. DNA and cellular structures provide evidence that all organisms share a common ancestor through natural selection. An example of natural selection is when organisms better adapted to their environment are more likely to survive and reproduce. Matter is anything that has mass and takes up space, while energy is the ability to do work or cause change.
What lives where and why preassessment
This document appears to be a pre-assessment worksheet for students. It provides background that the class will be studying a pond to understand what lives there and why. It asks students to imagine they are tasked with observing and collecting data about the pond to report back to the class. The worksheet contains 5 questions for students to answer in complete sentences about their imagined observations of the pond, including how long they observed it, what they saw/heard, if they took any measurements and with what tools, and what living things they saw.
Grade profiles
The document describes the grading system and what each letter grade represents in terms of student understanding and skills. An F represents a failure to understand biological thinking and complete required work. A D demonstrates a minimal level of understanding. A C shows inconsistent skills and understanding. A B shows more strengths than weaknesses with good reasoning skills. An A demonstrates excellence with no major weaknesses. The grading is based on tests, exams, assignments, labs, quizzes, and class participation and discussion. Effort does not directly affect the grade, but influences performance.
Intro to cellular respiration
To ease into cellular respiration student played a trivia game to introduce them to some of the key players in cellular respiration.
Potato catalase pictures
This document discusses a potato catalase experiment where potato mash was prepared and heated to different temperatures, with results from the experiment to be shown. Potato mash was prepared and some was heated while other samples were kept at room temperature or cold, to test the effect of temperature on catalase enzyme activity.

Heart rate lab report
- 1. Heart Rate Lab Report Use this guide to write your lab report.
- 2. This lab report only needs to contain the following sections: A proper scientific title A 1-2 paragraph introduction Results section Discussion section Literature Cited/Bibliography
- 3. Title A scientific title generally has: 1. The factor that were changed (jumping). 2. The thing that was measured (pulse). 3. The specific organism that was studied (7th grade Homosapiens). Here is an example: "The Effects of Light and Temperature on the Growth of Populations of the Bacterium, Escherichia coli "
- 4. Introduction Should contain your hypothesis. Your introduction should include relevant background information about the heart and the circulatory system. At a minimum you should include the following information: A description of the circulatory system What is a pulse? Examples of stimuli that can increase heart rate
- 6. Literature Cited / Bibliography You MUST give credit for your sources! You MUST cite at least two sources of information in your introduction. Make sure to use quotation marks around words that are not your own original ideas/words. Use a footnote (a small number at the end of the sentence) to show that what you are writing comes from one of your sources in the bibliography. For example: “A heart attack occurs when blood flow to a section of heart muscle becomes blocked” (1). The (1), refers to the first source in the bibliography
- 7. Formatting & Grammar You must type your lab report. A printed copy is due in class. If you do not have a printed copy, it is late. Each day it is late, a letter grade is lost. After three days, the assignment will not be accepted. Spelling and grammar count! Your lab report should be NO MORE than two pages.
