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

In this activity on page 3 of the PDF, learners investigate how much sugar is in a soda. Learners use sugar cubes to measure and calculate the amount of sugar in a bottle of soda.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

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.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

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

In this environmental health activity, learners investigate their own vital lung capacities.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

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

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

Get all wrapped up in a lesson about skin!

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

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 activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.
