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

In this activity, learners build their your own seismograph with household materials to document shaking.

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

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

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

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
