Students were asked to sift as many different sizes of pebbles, gravel, and sand as they could and to separate them into cups.
Next, they had to choose a label for each cup.
There were five categories at the end of the investigation.
The big idea of this lesson is that large rocks break up over time and eventually turn into gravel and then sand. The saying to remember this is:
Rocks into pebbles,
Pebbles into sand.
I really hold a million,
Rocks in my hand.
The students had a blast during this lesson. Special thanks to Mr. Dyer for helping us with sifting and sorting. I was so impressed with the team work the students showed during the clean up of this lesson! As you can imagine there was sand and gravel all over the room! But by 3:25 the room was spotless again. What a great class! Stay tuned for the Science Notebook portion of this lesson. Have a great weekend!
