Participants are assigned specific roles, with tasks including pouring sand, blowing through straws, and keeping time during the experiment. The experiment consists of multiple parts involving varying blowing techniques and observation recordings.
Sandblaster Experiment
- 2. Safety - Do not throw the sand - Do not swing the timers around (if strings are present) - Remember to close the lids on the sandblasters - Be careful to not inhale the sand
- 3. Directions Assigned Tasks- Materials Manageris in charge of pouring the sand through-out the experiment. The next three team members will each have their own straw. -Your task will be blowing the sand. The fifth memberwill be the time keeper (stopwatch). If you do no t have a fifth member, the Materials Managerwill be the time keeper.
- 4. 1. Pour four scoops of sand in the middle of the sandblaster Your bifold has these instructions listed.
- 5. 2. Record your “before”(Part A) picture then close the lid Straw Part A (Before):
- 6. 4. For 30 seconds, blo w g e ntly towards the sand. 3. The first person to the right of the Materials Manager will insert their straw into the hole of the sandblaster. ( Time Keeper! Remember to keep track of time.)
- 7. 5. After 30 seconds, remove the lid and record your observations in Part B.
- 8. 6. Once you’re done recording, pour the sand back into the cup. Try to not spill!
- 9. 7. Pour four new scoops of sand into the middle. Close lid.
- 10. 8. Blow harder (but not too hard!) for 30 seconds. This time, the next team member will use their new straw to blow harder.
- 11. 9. After 30 seconds, remove the lid and record your observations in Part C. Part C ( After 30 seconds, blowing harder ) Straw
- 12. Step 10 Without taking the sand out from Part C, dump ALL of the sand from the cup into the middle. Close lid. Use a new straw ( next team member ). This time, blow as hard as you can!! For 30 seconds. Record in Part D.
