Week:4 trebuchet

Week:4 trebuchet
This week we have used a trebuchet for our science experiments. On the first few tests the tennis ball didn't go that far because we had less weight but when we put more weight in the tennis ball went further. When we used a harder tennis ball the ball didn’t go that far. Why because the harder tennis ball it would of made it harder for the trebuchet to fling the harder tennis ball.
My data gathering is multistructural because I am confident about the accuracy and reliability of my observations-e.g. Would other people see what I see/measure what I measure etc.
