In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

This activity (page 2 of the PDF under SciGirls Activity: California Fish) is a full inquiry investigation into environmental adaptation.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity about heart health (on page 34 of the PDF), learners measure their own blood pressure using an electronic blood pressure monitor with a self-inflating cuff (included in cost of materi

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

This activity (on page 2 of the PDF under SciGirls Activity: Rabbits) is a full inquiry investigation into observing, recording, and graphing animal behavior.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.
