Giving Water the Treatment
Source Institutions
In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
Having a Gas with Water
Source Institutions
In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
