3.11 hsw imagine something unseen
The document discusses early scientific ideas about matter and particles. It describes an ancient tale where six men were asked to identify an elephant in the dark by touch alone, with each man mistaken about what part they touched. It also discusses how ancient Greeks believed all matter was made of four elements with different properties based on their composition. The document questions how scientists can know particles are real if they cannot be seen, and describes early models where particles of fluids were thought to be rounded and particles of solids jagged.
Theories Of The Universe
The document discusses several theories about the origins and formation of the universe:
1) The Big Bang Theory proposes that the universe began as an extremely dense, hot point that exploded outward and formed the ingredients to make atoms.
2) String Theory suggests that the universe is composed of 10 or 11 dimensional strings that reach other dimensions.
3) The Creation Theory from religion holds that God created Earth and the heavens over seven days, forming matter through mythical energy.
However, the document notes that while some theories are more logical than others, none can be definitively proven or disproven with the current scientific evidence.

Life Science Chapter 1, Section 2 The Study of Life
Life science, also known as biology, is the study of living things including animals, plants, fungi and microbes. Life science has several branches of study that often overlap, focusing on topics like how organisms are diverse yet share characteristics like being made of cells, requiring energy, and growing over their lifetimes. Groups of organisms evolve over many generations through the gradual process of change known as evolution. The structure and function of organisms are complementary, with an organism's structure allowing it to perform functions necessary for survival. Organisms also operate based on the same physical principles as the natural world.
Scientific Method Mod
The document discusses the nature of science, defining it as a way of learning about the natural world through observation and asking questions. It explains that science uses the scientific method to investigate phenomena through steps like forming hypotheses and drawing conclusions, though answers may change with new evidence. The three main branches of science - life, earth, and physical sciences - are introduced along with examples of questions and topics each aims to explain. Models are described as tools used in science to communicate ideas, test predictions, and save resources. Types of models include physical, computer, and conceptual models.

Scientific rigour is worth melting for MRS Annual Conference 2016
Scientific rigour is worth melting for MRS Annual Conference 2016Annie Pettit, Research Methodologist
In the first of a two-part session, four research professionals throw caution to the wind and fight for their passionately held beliefs about the way the insight world works. This is the session for those who want to hear the uncensored, unshackled and revolutionary voice of research.
I wish I had kept track of every time a conference speaker said they didn't understand the statistics they were referring to but if anyone had a question, they could find someone to answer it.
I wish I had kept track of every presenter whose 20 slides consisted of 20 pictures.
I wish it was even possible to count the number of infographics floating around the interweebs spewing countless unsubstantiated and out-of-context percentages with multiple decimal places.
In this presentation, I will plead with the audience to reconsider how they communicate to their clients about research, and how they present that research to various audiences.

3.11 hsw imagine something unseen
The document discusses early scientific ideas about matter and particles. It describes an ancient tale where six men tried to describe an elephant by touching it in the dark, with each man mistaken about what part they touched. It also discusses how ancient Greeks thought everything was made of four elements with different properties based on their composition. The document questions how scientists know particles are real if we cannot see them and describes early models of particles as either rounded or jagged based on whether substances were fluids or solids.
2.6 what is a wave
This document defines key terms related to waves, including displacement, oscillation, amplitude, frequency, wavelength, and wave speed. It explains that a wave is a disturbance that moves through a medium, caused by something vibrating in that medium. The key properties of waves - amplitude, frequency, wavelength, and wave speed - are defined and their relationships are shown in the equation that relates wavelength, frequency and wave speed. Examples are given of how changing wavelength would affect a wave.
5.3 astronauts keep cool
This document discusses how astronauts stay cool in space by describing heat transfer through solids and how the materials in the Space Shuttle are designed to reduce heat transfer. It aims to explain conduction and how insulators work, as well as analyze data to make predictions about heat transfer. Key terms introduced are conduction, conductor, and insulator. Questions are provided to test understanding of these concepts and how they apply to everyday objects and challenges of space travel.
Semi conductor
1. Semiconductors can experience thermal runaway as temperature rises, releasing more charge carriers and allowing greater current flow, further increasing temperature in a positive feedback loop.
2. The mechanism is that higher temperatures provide enough energy to some atoms to ionize electrons, increasing the number of free carriers proportional to the Boltzmann factor.
3. Plotting the logarithm of current versus the inverse of temperature produced a straight line as expected, confirming the conduction is proportional to the Boltzmann factor and allowing estimation of the energy needed to free a charge carrier.
14.2 boltzmann factor
The document discusses the derivation of the Boltzmann factor e^(-ε/kT). It explains that processes occur when a particle's energy ε is a multiple of the average kinetic energy kT per particle, such as 20-30 times kT. While unlikely, particles can gain this extra energy through random collisions with other particles. The chances of gaining enough energy to overcome an energy barrier ε decreases exponentially with increasing ε/kT according to the Boltzmann factor. Therefore, the rate of a reaction is proportional to e^(-ε/kT).
1.12 how did the universe begin
The document discusses evidence that supports the Big Bang theory of the origins and evolution of the universe. It describes how observations of distant galaxies provided evidence that the universe is expanding from an initial extremely dense and hot state around 13.7 billion years ago. It also mentions how the cosmic microwave background radiation provides major support for the Big Bang theory and how computer models are used to simulate galaxy formation from the early universe.
2.5 efficiency
This document discusses the efficiency of energy transformations and calculations. It defines efficiency as the ratio of useful energy output to total energy input. An example is provided where a desk lamp with 100J input and 5J output has an efficiency of 5%. The document also mentions the three types of heat transfer that work across different states of matter and encourages activities to identify energy waste and calculate efficiency from input/output data.
Sunrider Nutrition Basics
This presentation briefly describes the SUNRIDER Nutrition basics and HOW they act to restore our bodies through the ¨Philosophy of regeneration¨ and reach optimal health.
2.1 Understanding energy
This document discusses different types of energy including potential, kinetic, light, sound, heat, and electrical energy. It explains that energy can be transformed from one form to another and provides examples of this, such as a girl running gets her energy from the food she eats which is then transformed into movement, sound and heat energy. A light bulb gets its energy from electricity which is then transformed into light and heat energy. The document also discusses how appliances at home and work convert energy from one form to another.
6.2 energy everywhere
This document discusses different types of energy, including potential energy which is stored or hidden energy that has the ability to do work, and kinetic energy which is energy of motion. It lists learning objectives about forms of energy and energy transfers. The rest of the document appears to contain questions at different levels about energy, asking about heat energy, potential vs kinetic energy, energy transfers, examples of potential energy storage, and drawing energy transfer diagrams.
4.3
The document discusses elements, which are the simplest substances that make up matter and cannot be broken down further through chemical reactions. Each element has its own symbol, sometimes using the first letter of its name, as there are more elements than letters in the English alphabet. Students are assigned homework to create a poster about an element from the periodic table highlighting its name, symbol, discovery, natural sources, and uses.
Mr rayner's revision thoughts
This document provides tips for effective revision. It recommends starting revision early with short sessions of 20-25 minutes each followed by breaks, rather than cramming. Revision should be done over an extended period with periodic review to best commit information to long-term memory. The optimal intervals for review are 10 minutes, 1 day, 1 week, and 1 month. Distractions should be avoided by revising in a quiet space. A variety of techniques beyond just reading should be used.
Unit 6 using mathematical tools for science wrong table
This unit introduces learners to basic mathematical tools used in science. It covers using the International System of Units (SI) for measurements, manipulating simple algebra, calculating experimental errors, and displaying/interpreting scientific data through graphs and charts. Learners will practice using these tools to solve scientific problems involving units conversion, equations, ratios, volumes, densities, and more. They will also explore methods for accurately collecting, recording, and presenting primary data from experiments.
5.5 in a state
The document discusses states of matter and changes between states. It explains that when particles are heated, they gain energy and move more, but when changing state the energy goes into breaking bonds rather than movement. As a result, the temperature stays the same during changes like melting. It also discusses plasma as the fourth state of matter, with different properties than gas.
6.4 bending light
The document discusses the refraction of light and how it causes optical illusions. It explains that when light travels from one material to another of different density, it changes direction. Specifically, light bends toward the normal when moving to a denser material, and away from the normal when moving to a less dense material. The document provides instructions for an experiment to observe and measure the refraction of light through a glass block at different angles of incidence.

435648123-Identifying-Real-or-Make-Believe-Fact-or-Non-Fact.pptx
This document discusses the difference between facts and opinions. It provides examples of facts, like "Pal has four legs" and "The sun is the center of the solar system," which can be proven true. Opinions, on the other hand, are personal feelings that can't be proven, like saying "Pal is the best pet" or "I have the best mom." The document contains activities where readers identify sentences as facts or opinions.
Paley's Analogy
Paley's analogy argues that design in the universe implies a designer, similar to how design in a watch implies an intelligent watchmaker. The document discusses criticisms and modifications of this analogy. It proposes that Paley's analogy could be strengthened by comparing an eye to a watch rather than the entire universe, since an eye's purpose is clearer. However, David Hume noted this revised analogy still may not prove the designer is perfect. The document explores counterarguments and suggests two types of valid criticism of the analogy - false premises or flawed logical form.
What is Science?
Science is knowledge through observation and experimentation. It is facts of principles gained by systematic study. In order to participate in doing science, we must adhere to a "philosophy of science:" There is order to the universe, humans are able to comprehend this order, and scientists should be able to repeat experiments. There are two major kinds of science - empirical science and forensic science. However, science can't answer a lot of questions, and scientists often make mistakes.
Predictable Pendulums
The document describes an activity where students design experiments to test hypotheses about how different variables affect the frequency of a pendulum. Small groups of students are given materials to build pendulums and test how factors like the mass, string length, and release angle influence a pendulum's oscillations. By testing multiple hypotheses, even those that turn out to be incorrect, students learn about the scientific process and how to properly design an experiment.
Sl l3 crayfish
Crayfish have identifiable structures that serve different functions. They have eyes, antennae, a carapace, pincers, swimmerets, and a tail. Male and female crayfish can be differentiated by the size of their pincers and shape of their swimmerets. Crayfish need a habitat with food, water, shelter, space, and opportunities to hide. They will claim territories and defend their shelters from other crayfish.

Scientists hypothesized that they could estimate the duration of mass extinction events by quantifying the amount of the element iridium found in a thin layer of clay between rock strata from the late Cretaceous period and early Cenozoic era. This thin layer of clay is found frequently between the final layer of Cretaceous rock and the initial layer of Cenozoic rock, representing an abrupt transition where many plant and animal species cease to appear in the fossil record. Scientists proposed measuring the deposition time of this clay layer by counting the quantity of iridium, as iridium abundances have been used to correlate strata and geological timelines at extinction boundaries.

The document describes an experiment to determine the laws of reflection. [1] Students are instructed to use a mirror, light source, and protractor to measure the angle of incidence and reflection of light rays. [2] They will shine light at a mirror from various angles and measure the corresponding reflected angles to see if the angle of reflection equals the angle of incidence. [3] By plotting their results on a graph, students can evaluate whether the evidence supports the statement that the angle of reflection equals the angle of incidence.
6.3 giant mirror
A village in Italy installed a large mirror on a mountain opposite their village to direct sunlight into the village. The mirror helped brighten the village by reflecting sunlight into the dark areas between the mountains. Villagers could now grow crops that previously did not receive enough sunlight. The mirror demonstrated how reflected light can help illuminate dark spaces.
