2. Question
What is the effect of the amount of water on the distance of the cap travels?
Shea

3. Hypothesis
We think the amount of water in the film canister will affect the distance that the cap travels. Maybe the more water we put in the film canister, the farther the cap travels. We think this because the pressure of the amount of water can affect the distance of how the cap travels.

4. Controlled Variables The amount of tablets. The wind current.
A good room for experimenting distances.
The angle of the launcher.
The size and weight of the cap.
The temperature of the room.
The place of the launcher.
(The controlled variables are the variables that have to stay the same during the experiment.)

5. Manipulated Variable/Independent Variable
Amount of water. (A manipulated variable is the variable that you test.)
Lucian

6. The Responding Variable
The distance the cap travels (A responding variable is the variable you measure.)
Shahmeer

7. Materials The material are ... Alka seltzer tablets (1 tablet)
Seltzer water (20 ml of water which can be more or less)
The launcher
Tape measurer
Post-its or tape to mark spot
Film canister and cap
Syringe
Cup
Shea

8. Procedure
Get your materials which are alka seltzer tablet(s), Seltzer water, a launcher, tape measure, post its or tape to mark the spot, film canister, cap, and a cup.
Place the launcher on your table or the floor.
Stay in a room with all windows closed so the wind does not distract the experiment.
Get a small cup and pour 20 ml in the small cup.
Get your alka seltzer tablets ready by your side.
Take off the cap.
Unscrew the screw on the film canister Put the alka seltzer tablet(s) in the film canister.
Get 20 ml of water in the syringe and get it all in the film canister quickly.
Put the cap back on quickly and accurate.
Tighten the screw.
Hold the in one place launcher tight.
Let it go and back up.
And suddenly it will pop out.
DO NOT take the film canister in your hands before the cap pops out!
Go to where the cap landed and measure the distance of where the cap landed with the measuring tape.
Mark it with tape until the you figure out the average.
Repeat but with a higher or lower amount of water.

11. Conclusion/Results
We have learned from this experiment that it depends. If you put too much water, the cap will not go farther, the distance will decrease. Our hypothesis was wrong. It turns out that if you put too little water it will not go really far. But when we tried it with 10 ml of water the cap went traveled farther the 5ml, 15ml, and 20 ml.
Camille

12. Additional Questions
What would happen if we changed the angle of the launcher if it had less water?
What if the height of the room be higher would the cap go farther?
Why did it go the farthest with 10 ml of water?
Luca

13. Things to Pay attention to ...
Get the perfect amount of water in the syringe and squeeze all of that water in the film canister. Don't let the water drop.
Don’t let the water spill.
Put the cap on the film canister quickly accurately and tightly before the cap pops out..
Do not take out the film canister in the launcher if the cap did not pop out or it might pop on you.
Keep a safe distance from the cap when it pops.
Keep a keen eye where it lands Not where it bounce's.
Stay at the side of the room so you can see where the cap landed.
