In this activity, learners explore the different heating properties of soil and water.

In this activity, learners make a barometer, an instrument to measure change in air pressure.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

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.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

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 (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

The demonstration/experiment provides quick proof that air has mass.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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

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

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

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 activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.
