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.
The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world . On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history ( phylogeny ). Each page contains information about a particular group, e.g., salamanders , segmented worms , phlox flowers , tyrannosaurs , euglenids , Heliconius butterflies , club fungi , or the vampire squid .

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.
Each PDF below contains the teacher edition, followed by the student edition. Click on a big idea to download all the labs associated with that section. Download the individual labs and appendixes by clicking on their specific titles.
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.
Welcome! Here you will find links to my lecture presentations. These are posted just before or right after the class lecture. Students : I have linked directly to the Powerpoint files so you can download them and view them at home.
