CER - Claim Evidence Reasoning
In this video Paul Andersen explains how the CER framework can be used to give explanations in a science classroom. In order to make a complete explanation a Claim must be supported by Evidence and Reasoning connecting the evidence to...

Practice 4 - Analyzing and Interpreting Data
Paul Andersen explains how scientists analyze and interpret data. Data can be organized in a table and displayed using a graph. Students should learn how to present and evaluate data.

Photosynthesis
Paul Andersen explains the process of photosynthesis by which plants and algae can convert carbon dioxide into useable sugar. He begins with a brief description of the chloroplast. He describes the major pigments in a plant (like...
Bozeman Science
Population Ecology
In this video Paul Andersen explains how population ecology studies the density, distribution, size, sex ration, and age structure of populations. Intrinsic growth rate and exponential growth calculations are included along with a...
Bozeman Science
Soil and Soil Dynamics
In this video Paul Andersen explains how soils are formed and classified. Weathering of rock creates particles which are mixed with water, air, and organic material. Soils are classified according to particle size, chemical makeup, and...

The Rate-Limiting Step
In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.

Homeostatic Evolution
Paul Andersen shows how homeostasis reflects of evolution through time. The endocrine system shows continuity through flatworms, earthworms and vertebrates. However the respiratory system shows change as organisms move onto land. The...

Human Population Size
In this video Paul Andersen explains how the world population has undergone exponential growth since the industrial revolution. Predicting the future world population is difficult because each country will grow at different rates....

What is Physics?
Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.
Bozeman Science
Momentum
Mr. Andersen explains the concept of momentum. He also shows you how to solve simple momentum problems. He finally shows you how momentum is both conserved and relative.

Energy Flow in Ecosystems
In this video Paul Andersen explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An explanation...
Bozeman Science
Cell Cycle, Mitosis and Meiosis
Paul Andersen explains how the cell cycle is used to create new cells. The creation of identical diploid daughter cells, through mitosis, is described. The creation of unique haploid daughter cells, through meiosis is also described. ...

Concept 2 - Cause and Effect
In this video Paul Andersen explains cause and effect its importance in science and engineering. He starts by addressing the chain of interactions that must be present to show cause and effect. He addresses the assumptions of...
Bozeman Science
Plate Tectonics
Mr. Andersen describes how plate tectonics shapes our planet. Continental and oceanic platers are contrasted and major plate boundaries are discussed.
Bozeman Science
Ecosystem Ecology
In this video Paul Andersen explains how ecosystems function. He begins with a description of how life on the planet is ordered from large to small in biomes, ecosystems, communities, population, and individuals. He describes the major...
Bozeman Science
Properties of Matter
Mr. Andersen surveys properties of matter. A brief discussion of Archimede's Principle, Charles Law, Boyle's Law, and viscosity is included.
Bozeman Science
The Origin of Life - Scientific Evidence
Paul Andersen discusses scientific evidence of the origin of life on our planet. He begins with a brief discussion of the age of the earth and ends with the future of humanity. He includes geologic, chemical and molecular data.

Energy Transfer
In this video Paul Andersen explains how energy can be transferred from one system to another. In a closed system the energy can be transferred as either work or heat. Thermal energy transfer is know as energy transfer through heat....
Bozeman Science
Conservation of Energy
In this video Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms (including chemical, mechanical, light, electrical, and thermal). In AP Chemistry students must be...

LS2B - Cycles of Matter and Energy Transfer
In this video Paul Andersen explains how matter moves from the environment into living organisms and back into the environment. Food webs are used to show how matter and energy move through organisms. Ecological pyramids show that matter...

DNA and RNA - Part 2
Paul Andersen continues his description of DNA and RNA. He begins with the structure of DNA and RNA and moves into the process of DNA Replication. He also describes the central dogma of biology explaining how DNA is transcribed to mRNA...
Bozeman Science
Simple Harmonic Motion
In this video Paul Andersen explains how simple harmonic motion occurs when a restoring force returns an object toward equilibrium. The two types of harmonic motion studied in AP Physics are the mass spring oscillator and the simple...

Mendelian Genetics
Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their...
