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 use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

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

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

This lab activity has learners create a pendulum with a one-second period.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
