In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
