In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

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

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.

This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

In this activity, learners will explore coding by arranging words and phrases to create an order of operations in this low tech version of computer programming.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

In this activity, "write" a secret message in genetic code as beads on a string.
