In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

Learners construct and launch paper helicopters.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

In this activity, learners investigate how geometry plays a role in perspective.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
