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.
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.
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.

Problem solving using the “work backward” method.
Prepared for 6th grade math
Objectives of Lesson/Learner Objective
The students will be able to demonstrate their problem solving ability by working backward through word problems both in small groups and by themselves. The students will be able to show their work and complete the word problems using the work backward method as a group with no errors. The students will complete word problems individually using the backward method with 90% accuracy.
Anticipatory Set/Motivation/Snappy Launch
With your head full of brains and your shoes full of feet, you’re to smart to go down any not so good street. (“Oh the Places You’ll Go”, by Dr. Seuss)
Everybody needs to be able to solve real-life problems, and going forward doesn’t always take you down the right street. Today we are going to discuss a problem solving method that requires you to work backward.
Materials Needed/Preparation
I will provide the students with worksheets containing word problems.
Students need pencils, have some on-hand in case students don’t bring a pencil.
Procedure
1. I will go through two word problems using the “work backward” method.
2. After going through the first problem, I will define the work backward term.
3. Split into small groups and have the students come up with a word problem that requires using the work backward technique to solve. Solve the problem on a separate piece of paper, but keep the answer a secret. Trade problems with another group, and solve their problem. Compare answers.
4. Provide a worksheet with a couple word problems that will require using the work backward method of problem solving.
Vocabulary
1. Work Backward: When given the result of a sequence of operations, you can work backward to find the amount with which the sequence began. Discuss this definition in terms that are meaningful for all the students.
Examples
Example #1 (work backward)
The cat in the hat went to the flea market and spent $9.75. He bought some green eggs and ham, thing # one, and thing # two. The green eggs cost $1, the ham cost $1.25, and thing #1 cost $3. How much did thing #2 cost.
(9.75 – 1 – 1.25 – 3) = 4.50
Work Forward: Check your work by adding up all the components to get the result.
Example #2 (work backward)
On Monday there are 50 star bellied sneatches on the beach. That day, 8 star bellied sneatches had their stars removed. On Tuesday, 13 more star bellied sneatches had their stars removed. On Thursday, there were only 19 star bellied sneatches left on the beach. How many star bellied sneatches had their stars removed on Wednesday?
(50 – 8 – 13 - 19) = 10
Work Forward: Check your work by adding up all the components to get the result.
Check for Understanding
While the students work in groups, I will be an observer, walking around, making sure all the students are engaged and working with the smaller groups or individuals to gage and ensure understanding of the conce ...

Chemicals will also be tested on worms to collect data on heart rate responses.
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.
Osmosis and diffusion post lab questions
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

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.
- To begin thinking
Potato catalase pictures

Smooth muscle cells are involuntary and found throughout systems like breathing and digestion, reacting slowly but enduringly.
Phylogeny & classification
The document discusses the evolution of biological classification systems from Linnaeus' original system to modern phylogenetic classification based on evolutionary relationships. It introduces key concepts like binomial nomenclature, phylogeny, clades, homology, molecular clocks, and the three domain system of classifying life into Bacteria, Archaea, and Eukarya. Examples are provided to illustrate phylogenies and how to determine evolutionary relationships between organisms from phylogenetic trees.
Mechanisms of evolution_basic
The four modes of evolution are mutation, migration, natural selection, and genetic drift. Mutation introduces new alleles and genetic variation, migration enables gene flow between populations through movement, natural selection adapts populations to their environment by preferentially reproducing beneficial mutations, and genetic drift changes allele frequencies randomly in each generation based on chance rather than fitness.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

What lives where and why preassessment
- 1. Name _____________________________________________ Date _____________ Period _________ ____Meets expectations _____ Needs improvement _____ Falls seriously short of expectations Pre-assessment: What lives where and why? Earlier today we went out to the pond which we will be using over the next few weeks to help us answer “what lives were and why?” One of the goals this year is to teach you to think like a scientist. These questions are designed to help me see what you already know. A few years ago the pond was completely drained and rebuilt. Lawrenceville students played a role in reshaping the pond. However before they could start to think about redesigning the pond, they needed to know what they were dealing with. Imagine you are one of these students and your job was to make observations and collect data to bring back to the class about the pond. Answer the questions below. Please write using complete sentences. 1. How long did you observe the pond? ______________________________ 2. What types of observations did you make? What did you see, smell or hear? 3. Did you take any measurements? 4. If so, what type of tools did you need to take these measurements. 5. What types of living things did you see?
