Explore scientific research that says continued brain activity may delay or slow the loss of memory function. Investigate and practice different techniques to increase recall.

Explore the human body's need for a normal cycle of dark and light and apply this to an understanding of biological clocks in other animals. Test the effect of light on the development of mealworm larvae into adults.

Investigate the science behind global warming with these classroom activities. Compare light and dark objects to see how they respond to light absorption and heat generation, and describe the albedo values of various materials.

Get your class thinking about climate change as a scientific theory. Guided by a handout, emerging earth scientists read articles and take notes about glaciers and sea ice. To conclude, they write an evaluation of the evidence for...

Investigate spiders in Panama that use UV-reflecting silk in their webs to attract their prey. Build a device that traps flying insects, experimenting with different light sources to choose the best lure.

Investigate the science and medical diagnostic uses of magnetic resonance imaging (MRI) technology. Perform experiments to observe how magnetic properties can be induced, and measure the force of temporary magnets.

Explore the techniques and steps in training an animal by attempting to train a classmate to perform a simple task without using known words. Train him or her to respond to a vocabulary of nonsense words with hidden meanings.

Research two species of primates, the lemur and the aye-aye, to discover their survival strategies and adaptive behaviors. Select another primate species to investigate and work in a cooperative group to gather information from many...

Explore the evolutionary advantage of stereoscopic vision and the fully opposable thumb, and describe how each adaptation might affect the use of tools in humans and primates.

Explore the effect of overcrowding on a population, and play a game that demonstrates what happens as a population loses its space. Investigate cooperation in social groups, the benefits of sharing food and what happens when the system...
