What's in a River?
You'll be amazed by all the things that travel down the watery highway of a creek! Make this gadget and see what you can catch.
What You'll Need:
- Wire coat hanger or piece of strong wire
- Screen or mesh
- Duct tape
Step 1: Bend a wire coat hanger into a rough circle.
Step 2: Take a piece of old screen, and bend it around the coat hanger. (Be careful not to stick yourself with the screen. You may want to wear work gloves or gardening gloves while doing this.)
Step 3: Apply duct tape to hold the screen in place.
Step 4: Go to a creek or stream with an adult. Put your screen into the current and hold it there for a few minutes.
Step 5: Take out the screen and see what the current has carried onto it.
You might find seeds that will land on the creek's bank and grow into plants. Or, you might find water animals such as insects, minnows, or crayfish. (Put them back in the creek right away, so they stay alive.)
You might even find something somebody lost a long way upstream!
The next science activity will put you in the mindset of a famous explorer.
