In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

Millions of organisms can live in and around a body of water.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

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 international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

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, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.
