In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners explore the concept of rotational equilibrium. Learners work in teams to estimate and determine the force within a mobile design.

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

In this math lesson, learners are introduced to proportional reasoning through modeling, sharing, and questioning techniques.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.
