In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

In this activity, learners will explore the water cycle by creating a small atmosphere.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
