In this activity, young learners (2 years and up) explore flower and plant biology and pollination by planting seed in a homemade seed starter.

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this activity, learners explore a bucket of sand and beach objects.
