In this activity, learners use their hands as tools for indirect measurement.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

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

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

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

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

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.

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

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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.
