Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
