Marshmallow Catapult

Marshmallow Catapult

Aim: To construct a marshmallow catapult and record the distance.

Equipment:
marshmallows
9 popsicle stick
rubber band
plastic spoons

Method:

1. Put one popsicle stick horizontally then place one vertical.
2. place seven more popsicle sticks horizontally on top of the verticle one.
3. Rap one rubber band on each side over all of the horizontal sticks.

5. Rap three rubber bands around the end of the spoon and the end of one of the vertical ends.
6. Add a big or small marshmallow to the scoop of the spoon and hold down the spoon, let it go and you've made a marshmallow catapult!

Results:

As you can see, there are a lot of numbers. Though these are our results. These numbers would eventually help us with the discussion.

Discussion:
From the average length and time, we were able to find the velocity ( the speed). Using these numbers (photos above), we were (Sam) able to calculate the averages. The averages were the most important of all because we could find out more through these numbers. Sam did her magic to smoosh all of the data into a small group of averages. As you can see, The photo under this is what the amazing Sam produced and helped us out with.

 Speed= change in distance/change in time

Acceleration= change in velocity (speed)/change in time
