This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

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

In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
