In Blazing a Genetic Trail, by the Howard Hughes Medical Institute, follow this three-step approach to treating genetic diseases.

In this activity, to learn about the biological needs of mosses, students will grow and maintain their own moss terrarium. Through daily maintenance and observation, students will identify those factors necessary for the successful cultivation of moss.

This OLogy activity teaches kids the many things they can do to preserve biodiversity. The printable checklist includes detailed examples in nine categories.

This article, part of Biodiversity Counts, provides insight into the important task of identifying plant specimens. The article includes a list of tools that are part of a botanist's field kit.

In this Biodiversity Counts activity, students create their own aerial insect net using common and inexpensive supplies: net fabric, a coat hanger, a wooden handle, duct tape, a sewing needle, and thread. The online activity page includes illustrated step-by-step directions and a brief introduction to the use of fabric nets.

This Biodiversity Counts illustration shows students how to make a simple killing jar to preserve arthropods for further study. As the labeled drawing shows, all that's needed is a jar with a lid, tape for reinforcement, a few drops of ethyl acetate, and a paper towel.

In this Biodiversity Counts article, students learn how to preserve their plant pressings.

In this Biodiversity Counts activity, students learn how to press and preserve plant specimens. The online page includes illustrated instructions about how to layer and maintain pressings until the specimens have dried.

In this Biodiversity Counts activity, students learn how to replicate an arthropod's natural habitat in order to create suitable guest quarters. The online page includes instructions for what to observe in an arthropod's environment, tips for converting a container, such as a soda bottle or aquarium, into a hospitable habitat with plenty of oxygen, water, hiding places, and other arthropod necessities, notes about what to feed the arthropod and where to purchase both arthropods and their food.

In this Biodiversity Counts activity, students learn how to set up a Berlese funnel and coax tiny arthropods out of their habitat for further study. The page includes a labeled illustration.

In this Biodiversity Counts activity, students learn how to set up a yellow pan trap to attract insects drawn to the color yellow. The supplies required are readily available.

In this Biodiversity Counts activity, students learn how to create and set up a pitfall trap to catch soil dwellers. The online activity page includes easy-to-follow directions for building a trap with recycled plastic containers, stones, wood/cardboard, and a bait of the students' choosing. Students let the trap sit either for a few hours or overnight to see what they have caught. To expand their investigation, students are challenged to experiment with different baits to see if they can attract different arthropods.

This online article, from Biodiversity Counts, is a general-purpose tip sheet for using a dichotomous key. The article outlines a three step process using a tree as an example.

Students learn how the human body self-regulates to maintain a stable internal environment despite changes in the external environment.

In this video segment adapted from NOVA: Judgment Day: Intelligent Design on Trial, learn how modern genetics and molecular biology offer compelling support for evolution. The video features an interview with biologist Ken Miller.

This video segment from NOVA: "Cracking the Code of Life" looks at the meaning and significance of the effort to decode the human genome.

This site assembles the information from the April 1997 American Museum of Natural History symposium on the role humans have played, and continue to play, in the extinction of species. It presents an overview of extinction, the various hypotheses that explain this irreplaceable loss, details about what happened 14,000 years ago and the ongoing role humans play in the extinction process, a bestiary with notes and illustrations about some of the mammals that have gone extinct from the Pleistocene era through the 20th century, and what can be done to prevent another extinction event.

This video segment from The Human Spark features a discussion about how human thought differs from that of chimpanzees.

Learn about the wildebeest and locusts on the move in this video segment from Nature.

In this video segment adapted from the National Film Board of Canada, learn how the Inuit people have used their traditional knowledge to understand and adapt to changes in their Arctic environment, particularly when hunting and navigating the landscape.
