Today in school we learned about friction!
We started by talking about riding our bikes and how we'd rather ride on a smooth road than on the grass. This was an easy connection to the idea of friction!
We moved onto an exciting experiment to test out the force of friction. We set up ramps and rolled Hot Wheels cars around!
I tried a LOT of combinations to make a good ramp with the supplies I had on hand in my room and in the building. Three textbooks and a file folder provide a nice, smooth ramp! We tucked the edge of the file folder underneath the stack of books to stabilize it a bit.
Then we tested the friction of three surfaces - the cafeteria floor, our reading rug, and a tumbling mat.
It was a really fun experiment, and everyone totally grasped the idea of friction!
In other news, we are having a legit birthday party tomorrow in my class. One of my parents emailed me today and said she is bringing a cake. If it wasn't a Friday, I might have hesitated....... but I did promise my class we could watch Scholastic's Taylor Swift reading webcast, so it kind of works out perfectly. :)
Hope you have a great Friday!
