Week4: This week we are learning about the trebuchet. A trebuchet is a type of catapult. I noticed that when it moves, the ball doesn't fall out when it swings over because the sling releases when a certain angle is reached. The ring connected to the sling slips off and the projectile is launched. I also noticed that the more weights we put in, the further it would go. The less weight we put in the less far it went. We also saw the wind was making a change to the flight path of the ball because the wind stopped it from going further than its full potential. I think my learning was multistructural .
