The Knock on Wood easy science project teaches kids that trees give us more than just a shady spot on hot summer days. Find the products that trees provide in the Knock on Wood project.
How to Knock on Wood:
Do you have a baseball bat? How about a pencil? Does your home have a wooden table or chairs?
There are so many things made from trees it's hard to count them all! Try to walk around your house and find as many things as you can that came from trees.
Look for wooden items, as well as paper and cardboard. Don't forget to count fruit -- such as apples -- that grow on trees.
In the next easy science project for kids, see what happens when liquid freezes inside an object.
