This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this activity, learners perform an experiment that replicates the dilemma faced by birds in acquiring food from a confined area.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.

In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.
