This week Grade 4 did a marble experiment. I made my own experiment by lining 5 marbles up. My marbles were in a line with 2 in a corner, one in the middle and two more in the other corner. I hit the first two so I gave them mechanical energy. They went till the one in the middle. The one in the middle went rolling till the other corner and the ones in the other corner fell off the ruler.

great job júlia
Hi Julia,
I’m glad you were able to learn about Newton’s Cradle. They’re a lot of fun. My grandmother used to have one and I played with it a lot. I hope you get a chance to play with one sometime.
Thank you Mr.Caleb
I didn’t know what Newton’s Cradle was but I read about it and now I know.
It is the same concept that my experiment but Newton’s Cradle repeats because it’s a pendulum.
This looks like a fun experiment, Julia! It reminds me of something called Newton’s Cradle. Have you ever heard of it?
