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

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

In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.

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

In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

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

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 math activity, learners read "The Button Box" by Margarette S. Reid and then make their own button boxes filled with different buttons.

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

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

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, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

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