And another
Groups were divided by ACT scores or grade point averages with one from each of four categories - very high, high, medium, low.
Each group was told:
1. Mass Matters.
2. Measure 10-15 mL of water in film canister.
3. Mass half an alka seltzer tablet.
4. Decide to use paper and/or cardstock for rocket.
5. Decide whether or not to have a nose cone.
6. Decide how many stablizers (fins) to have from 0-5.
7. Predict how high it will go in centimeters.
8. Predict how long it will take to blast off in seconds.
9. Mass the rocket empty.
10. Record all the results including the actual height and actual time.
These are the results.Alka Rocket Data Sheets for Six Classes
