When "Monster" Pendulum Meets Sidewalk Paint
Our exploration of pendulums continued today with a "monster" sized version of pendulum painting on our parking pad. We use a rather tall portable coat rack. (You can see in the photo, I'm about 5'2" tall, so we had a tall pendulum to work with today.) We also made sure that the string for the cup was long enough that our short friends could reach it when it was their turn.
Instead of liquid tempera like we used yesterday, we opted to make some homemade sidewalk paint. I know that I saw this idea when it was posted on Teach Preschool, but I cannot remember who/where it came from. (If it was you, let me know and I'll give you the credit!) All you need to do is mix cornstarch with water and a little bit of food coloring. I found that it was about a 50/50 mix with a few drops of color.
The beauty of this sidewalk paint is that it is all natural and biodegradable. We made a large batch and put it to the test with our "monster" pendulum.
While we were waiting for our turn with the pendulum, we watched and painted our own pictures on the sidewalk.
Everyone had an opportunity to choose a couple of colors and swing the pendulum.
"Look at that... the paint is coming out of the top and the bottom!"
.... I wonder what happens if I just throw the paint on the sidewalk????
Can we use regular sidewalk chalk too??? Of course we can!
I wonder if anyone will pull up onto the parking pad today???
