In this nutrition/food science activity, learners conduct an experiment and record data to compare the amount of fat in different foods.

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.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

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 health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

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

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

This math challenge, played with two players or a whole group, engages your problem solving skills.

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 math activity, learners use gingerbread cookies to collect and organize simple data. First, learners read "The Gingerbread Boy" by Paul Galdone.

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

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent
