In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this activity, learners discover why only some types of plastic can be recycled.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

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

In this activity, learners perform an experiment to find out what determines a flower's color.

This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

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

In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

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

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.
