We made a bottle rocket that launches from shooting water into it. This ties into math because we calculated the distance from both time in the air (physics) & the angle of elevation (trigonometry)
Wings and Fins
We added 3 fins to our rocket for stabilization. This is to prevent wobbling & excessing spinning during the flight
Rounded Corners
The bottle is manufactured with rounded corners, so we didn't want to ruin that by adding any body design elements to the top of the bottle
Nose Cone
For our nose cone, we used the top of another bottle & put it onto the bottom of our bottle. We turned the base of the bottle into the nose because it's the part that launches up. ​
We drew out rough sketches as we built the rocket so that we didn't spend too much time iterating before we figured out what would work. As we wanted to add more design elements to the rocket, we drew them out, bot on our design doc & on the cardboard itself
After the construction of everyone's rockets was complete, we launched them by shooting water into them on the school field. One person had to record. One person had to measure the angle of elevation for the distance calculation. And one person had to pull the string to release the water into the rocket. Our rocket was in the air for about 3 seconds
