Using the catapults I blogged about yesterday as well as some pom poms, Hot Wheels cars and various other small items, the boys and I tested our catapults.
Cutie Pie hypothesized the spoon catapult would send an object the further distance.
Our First Tests:
First we lined up the catapults.
Next we found items of the same shape and size and flung these from each catapult (pom poms, etc).
We marked how far our items were flung.
We repeated the process.
We then repeated the process with different items, noting the weights and sizes of items were flung different distances.
Our Second Tests:
We used different items of similar shape and size.
First we used the bottle cap catapult and marked the distance obtained.
Then we used the item of similar shape and size, but used the spoon catapult and marked the distance.
We repeated this process with each item on the opposite catapult, each time noting the distance obtained and discussed the differences and possibilities for the different distances.
Conclusion:
Cutie Pie’s hypothesis was correct, at least when I was manning the catapults.
Sweet Pea and Cutie Pie manned the catapults, too, but their results varied greatly, but they were also a little inconsistent in the starting point. It was great practice in coordination and fine motor skills for all of us!
