Today we had a project to do. We had to make a catapult out of ,

• Large Tongue Depressor
• Tape
• Water Bottle
• Dixie Cup

It was a hard project but of course we did it! This took me three times to get it to work properly. The first trial it worked, just didn’t go far, the second trial the ping pong ball would not go out of the Dixie cup, my third trial worked but didn’t make it off the grid so I didn’t go into the showdown. The showdown was just testing your catapult and taping the mark of where the ping pong ball hit and writing your name on the tape.

Rules:

1.  Once the ping pong ball bounced that was where it’s mark was
2. We could only use our materials to make our catapult
3. You are aloud to rip your materials but you are not aloud to open the water bottle

I loved this unit because we always did fun experiments!
