Catapult Project Day 2

Today we finished off the catapult project by having each group fire their catapult from the top of a desk instead of flat along the floor. The students had to modify their original equation to factor in the height of the desk. Then they had to use their new equation to predict where a target should be placed on the floor. Part of their grade was based on how close they came to hitting a bullseye!!!

I had one group hit the bullseye dead centre. Most of the groups were within about 15 cm of the bullseye.

We ustreamed the final catapult firings so that anyone that wanted to watch was able to.

Thanks to Jared Nichol and Neil Stephenson for following along and chatting during the ustream. My students thought that was quite cool!!

I have also created an excel spreadsheet to help grade this project.

You can obtain the description of the actual project and the rubric from yesterday's post.


  1. Is there any way to view the catapult firings now? Are they saved in ustream?

  2. Sorry, we forgot to record our ustream. So it is not available.
