Nutrition, Metabolism, and Temperature Regulation We are often more concerned with the taste of food than with its nutritional value when choosing from a menu or when selecting food to prepare. Knowing about nutrition is important, however, because food provides us with energy and the building blocks necessary to synthesize new molecules. What happens if we don't obtain enough vitamins, or if we eat too much sugar and fats? Health claims about foods and food supplements bombard us every day. AP Biology Labs and Handouts « School Without Walls Biology Here you will find the labs and handouts for AP biology. Many of the links will be to external sites. Credit is given to original authors when possible. Online lab resources LabBench hosts online labs with prelabs. Before each lab, please go through the prelab and note any questions you have about concepts, lab techniques or data analysis.UC Open Access has a complete AP biology course.

A simple model for natural selection In this simple procedure, grains of rice are used to model small organisms, and students act as predators selecting food during limited time spans. Over a number of generations, the proportion of grains of rice of each colour in each population will change if students select one colour in preference to another. This is a simple model for natural selection resulting from predation. AP Biology Investigative Labs Supplement to the first printing: This Supplement to the First Printing of the lab manual includes updated URLs, corrections, clarifications, sample data tables for Investigation 7, and an updated version of the AP Biology Equations and Formulas appendix. The second printing of the Teacher Manual, available for download below, incorporates these changes.
The Loom Your hands are, roughly speaking, 360 million years old. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today.
MOLO - Proteins: From Sequence to Structure Overview By working their way through a series of models of polymers of increasing complexity, students can recognize forces responsible for protein's 3D shape. They compare folding of the same chain of amino acids in water and lipids, experiment with different sequences of amino acids and learn how charges, polar and non-polar amino acids affect the shape of a protein. Then students apply this knowledge to the case of Sickle Cell Anemia, in which a single point mutation causes the replacement of charged amino acid to a non-polar one, resulting in a misshaped protein.
