Toothpick Fish

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Here's an unusual approach to ensuring the survival of a species! Introduce young biologists to the California grunion, a fish that mates on land rather than in the water. The video shows how grunion make use of time and the tide to...

Survival is a game of chance, catch my drift? Examine the factors that influence genetic drift with an entertaining video from a large biology playlist. The resource covers the myriad conditions that come into play when a species...

Discover what a population is in regards to an ecosystem.

Modern industrial fishing has disrupted many ecosystems. But will fishing techniques ever cause the oceans to run out of fish? Watch a video that explains the effects of overfishing.

If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

For scholars tired of reading the textbook, this unit includes nine hands-on lessons. Through group work, lab activities, experiments, and even one inquiry-based lesson, scholars apply knowledge about cells, genetics, and...

Solve the mystery of a declining frog population! Lead your junior ecologists on an investigation that simulates actual events concerning pollution, predation, poaching, and more. Investigators read a story online, then analyze survey...
