Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.
