In this activity, students are provided with a list of supplies that survived their plane's crash in the Amazon jungle. They will organize the supplies to classify which items are useful for surviving in the Amazon. Students will use estimation and basic math skills to determine how much they can carry and to decide on what items to bring with them to survive in the Amazon until they reach their destination.

Students learn about endangered species and actions humans have taken to address the issue of endangered species. The Xpeditions lesson has students think about their experiences with zoos, learn about the reasons for captive breeding, and come up with an opinion about the role of zoos and aquariums in addressing this issue. The additional activity in the Teaching Materials section has students learn about a controversy within the scientific community regarding the captive breeding of tigers. Students will read articles written by the scientists, develop an opinion, discuss the issue with their classmates, and draw a conclusion based upon additional information they have researched.

In this activity, students use questioning skills to ascertain which pond plant or animal they are. In previous lessons, students have visited the neighborhood pond, made observations, and become familiar with pond life.

This activity is a field investigation where students collect bugs using homemade pit traps, sort them into groups, and then graph their results.

This lesson guides students to examine the potential benefits, risks, and ethical concerns of designer drugs. Students begin by reading an article titled Ethical Issues in Pharmacogenetics by Carol Isaacson Barash, an ActionBioscience.org original article. Next they will read information on the National Human Genome Research Institute on Pharmacogenetics: Frequently Asked Questions about Pharmacogenomics. Instructors can then use the lesson to guide students through shorter activities and/or one main activity. The smaller activities involve students in describing the research behind the issue, making it accessible to a less-informed audience, and in exploring the ethical issues outlined in the article to support various points of view. The larger activity is for upper level students to gather evidence to support particular perspectives so that they can present different views about the ownership of human DNA information.
