catapult

 For the past couples of weeks in blast off Me and my buddy Ciara have been building catapults. at first we built three catapults that was the teachers design. Next we planed to make on of our own but we could not find the planing sheet so this is our poster for our catapult.

    

Robe Goldberg Machine

In blast off (class) Me, Ciara and Madeleine made a Rube goldberg machine.

 It went really well but the glue stick we had in it was to close to the car track but the marble did go in the cup so that was good and that was the goal 

this is our final design

this is our final video
