Bounciness

Students continued to compare the bounciness of different balls today.  As a class, we determined that in order to figure out which ball actually was the"best" we needed to conduct a fair test. The children realized that different variables affected the results from last week's test. Some students had been bouncing on the table, while some on the desk, and some on the carpet. Also, some students were applying more force than one another, and students were dropping the ball from different heights. We concluded that a fair test had to be given to determine which ball actually was the, "best." INQUIRE with your child which variables remained constant. Unlike last week, this time we decided to measure the height each ball goes after the bounce to determine the "best" bouncer as opposed to attempting to count the number of bounces each ball had. The results were recorded on a class graph. We used the results to determine 1st, 2nd, 3rd, and 4th place.
