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

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

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

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

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

Learners build a wind turbine and test it to see how much energy is created.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Using simple, inexpensive items, learners build and test submarine models.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.
