What we will need?

Pebbles/rocks and safety goggles.

What we will do

Find a big boulder and get some rocks and start scraping the rock on the boulder.

We will comepere the rocks to see which rock was scratched the most.

How we will keep safe? Make sure no one is in your way if you are on a high thing make sure you wont fall off. Make sure you are with adult.
