Step 1: Final Launch
During our launch preparation, we discovered that we could not take video and collect data with Google's Science Journal app at the same time. To solve this problem, some children decided to attach two phones so they could take video from their rocket using the second phone. Other children attached just one phone that collected the data.
Once our rockets were ready to be launched, we made sure Science Journal app was on and recording. We were so excited to record our flight and learn how far our rocket went!
Step 2: Deeep Understanding of Movement
During the days it took to launch all our rockets, we kept learning about movement, spacial mapping through X, Y, Z coordinates, gravity, and friction. Collecting data about our rockets can help us to understand which parts of our design solved air friction. How high does the rocket go? How many phones can be attached to the rocket without affecting its direction too much?
Experiencing the rocket launch and the iteration process of making it supported our understanding of movement. We learned to slow down our rockets using air resistance and a parachute. We also learned that a nose cone can make our rocket more aerodynamic when it is being launched. We further learned that the amount of water used to launch the rocket and how fast we pump air in are both related to how high the rocket goes.
