AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, and...

Students solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. For this forensic science lesson, students identify the different blood types. They explain how blood tests work.

The purpose of this lesson is to prepare students for exploring the biological basis of vaccines. Students will explore the nature of viruses, specifically their structure and ability to adapt through evolution.

The focus of this chemistry video is kinetics, which is the study of precisely what happens to compounds when they react together. Specifically, kinetics is the study of the rate of chemical reactions and the forces that affect that...

Do the ends justify the means? Getting a drug approved in the US is a long and involved process. But at some point out, it involves testing on humans. The ethics of such testing is the focus of a resource that uses Dr. Albert...

Introduce the concept of hypothesis testing, confidence intervals, and degrees of freedom with a short video that also covers the chi-square test and works through several examples to help viewers understand the material.

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

Animations showing how the different parts of the immune system respond to vaccination and how that response protects the body from a specific disease in the future. After viewing the animations, students do an activity to test their...

If you want to check your understanding of immunology, this is the place to go. This resource has 13 different questions to test your knowledge, as well as tutorials that go with each question.

Enzymes create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a "catalyst." Enzymes are biological catalysts - they...
