What You Do

Have your child collect dirt samples from several different areas and spoon them into the jar until it is a quarter full.
Add water until the jar is two-thirds full. Take turns shaking the jar vigorously for two minutes, then allow the contents to settle for 15-30 minutes.
What happened? The largest (heaviest) pieces of soil will have settled to the bottom first. Smaller particles will settle on top. There will be some particles that will stay suspended in water — these are the lightest particles.
Learn the names for these different-sized particles in our Did You Know? section!

Sign the pledge to spend time outside and encourage the kids in your life to get outside more, too!
