In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

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

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this activity learners will build a neighborhood out of blocks and cardboard.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners will make a marionette puppet and put on a show. Learners will explore color, design, fabrication and storytelling through this activity.

This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.
