Ball tube course

This fun activity teaches cause and effect and critical thinking. The kids really had to think about where they thought the ball was going to end up. We made this like a marble run but we used a bouncy ball, TP rolls, colored duck tape, magnets and the fridge of course. it was a lot of fun and it would be a great rainy day activity. Instructions are really simple;
1st save different size cardboard tubes,
2nd get different color duck tape and cover the tubes,
3rd place round magnets with sticky backs on the tubes. Make sure you use the round one instead of the long strips( the round ones hold to the fridge better). Also put at least 4 magnets on the paper towel sized tubes and 2 on the TP ones.
Another tip, make sure you have a ball per kid or they tend to fight over it.
This was part if our Letter T lesson.
