Impromptu lesson...

Jake got some erasers in the shape of a bowling ball and bowling pin.  He created a tube to put the ball in.  We measured and recorded the height on each end and the length of the tube. We each marked off a spot where we thought the ball could go the farthest to knock the pin down and then where we thought it had the best chance of knocking the pin down.  We took turns trying the ball out with the pin on our marked spots and recorded the results.
