Hover Crafts

Hover Craft Project By Guest Student Blogger Natalie
Our class made hover crafts with Mrs. Sabatini. We were doing it to see which hover craft would go the farthest. The materials we used were a CD, the top of a bottle, and a balloon. On the first day we met we built it and put 1 hole in the bottle top. The next day, we blew up the balloon and attached it to the bottle cap. We tested the hover crafts by letting the air out of the balloon which made the hover craft move down the ramp.  We timed them and we gave the hover craft a nudge down the ramp.  Then we put the initials on a sticker and put it on the graph. Then we repeated the process two more times. So when we finished the process we had 3 holes in the hover craft. When we finished we put it on a graph that was in our packet and drew a picture. After that we talked and looked at the data that was on the graph.  
Which hover craft do you think traveled the farthest, one hole, two holes, or three holes?
