Section Warm-Up
Gather the following materials from around your house:
- a kitchen measuring cup
- a set of kitchen measuring spoons
- an eyedropper (like a standard medicine dropper)
- two small drinking cups
- some water
Follow these steps:
- Fill the measuring cup so that it has exactly one cup of water in it. This represents all the water on Earth.
- Next, remove ½ tablespoon of water from the measuring cup and place it in one of your small drinking cups.
- Next, use the eyedropper to remove just one drop of water from that drinking cup and place it in the second small drinking cup.
How does this relate to the water resources we have on Earth? Roll over each image to find out.
