Learners take on the role of environmental engineers as they design water filters.

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

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

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

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, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this activity (Lesson 1), learners work in groups to create tide simulations.

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

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

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.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.
