I designed this investigation for AP biology though it could be modified to work with students in introductory biology classes. First students learn the four macromolecules important to life: carbohydrates, lipids, proteins, and nucleic acids. They can then venture into the lab where they use indicators to test for the presence of these molecules in…
Food webs are basic concepts in biology and ecology, where students learn the concept of energy flow in an ecosystem by viewing models of food webs. This labeling worksheet asks students to identify the primary, secondary, and tertiary consumers in a forest ecosystem. Students then identify which animals represent carnivores, herbivores and omnivores. As…
Students open owl pellets to reveal the skeletons and fur of the owl’s last meal, and then reconstruct the skeletons using an bone chart.
