In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft. Using baking soda and vinegar, learners model volcanic eruptions and...

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world. Learners work in teams to engineer their own dam structure...

In this activity, learners explore how engineering has developed various means to remove impurities from water. Learners work in teams of "engineers" to design and build their own "...

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air. Learners work in teams of "engineers" to design and build their own...

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion. Using both math and science skills, learners gain awareness of how human activities...

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes. Learners will use gelatin to represent a cell and dye to...

In this activity, learners explore how to protect their skin while applying pesticides to plants. Learners conduct a series of simulation experiments and discover that some clothing fabrics provide...

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms. During a low tide, when many organisms are not covered by water, learners...
