Week 4 science journal

Trebuchet
                                                  Week.4.
This term we used the trebuchet. When you put more weights in it would go further and if you put less weights in it wouldn't go as far. The one that had more weights in went further. At first I wondered that the one with less weights would go further because it's less in it and it would easily just flick. I also wondered why the hockey ball didn't go as far as the tennis ball? Maybe because it's heavier and the tennis ball was lighter. The forces we used were push and pull. I am at multi-structural for inferring and gathering data because I have many ideas.
