In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

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