On the Ball, the Ratburgers conducted a scientific investigation to discover which sports ball was the most bouncy. We found eleven different balls in the junior sports shed. We had to test each one a number of times and record the result each time so that we got reliable data. then we calculated the average number of bounces using addition and division. Next we plotted the averages on a bar graph and wrote a statement about what data told us. We were surprised to find out that the ping pong ball was the bounciest ball at Cockle Bay!

| Caleb recorded his results methodically. |
 |
| The spider ball was the easiest to catch! |
 |
| We calculated the average by adding up all the bounces and dividing by the number of bounces. |
 |
| We plotted the averages on a bar graph and made statements about our data. |
