This week we had a chance to look at the data from our design challenge and see how we could make our designs better. As a class my scientists observed that some devices launched the pom pom very far, whereas other devices only launched them a short distance. They inferred that the devices that were able to build leverage or greater force, propelled the pom pom much farther. They also observed that many designs resembled a sling shot or a catapult. Then, we had a chance to re-examine the materials and see what we could have done differently to make our pom pom travel even farther. Part of being an engineer and a scientist is looking at data and making improvements to our prototypes. |
