Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

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

In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
