2. Question What is the effect of water on the distance
of the temperature
of water
on the distance
the cap
travels?
Kaya

3. Hypothesis
We think when the water in the canister is hot the cap will go farther because the hot water will boil the alka seltzer tablet, and make the cap go farther. We think that if we use cold water it will freeze the alka seltzer tablet a little and will make the cap go slower and will not go far.

4. Controlled Variables Weight of cap 1 Alka-Seltzer Tablet
Launcher at 450 Angle
Neal
20 ml of Water
The speed of the wind
The placement of the launcher

5. Manipulated Variable
The temperature of the water is the manipulated variable.
Tali

6. Responding Variable
The distance the cap travels is the responding variable.

8. Procedure PLEASE BE WARNED :
Ask the teacher to get you a cup of water at F (Room Temperature)
Then,get the syringe.
Fill the syringe up to the 20ml mark.
Squirt the 20 ml of water into the film canister.
Put alka-seltzer tablet into the film canister.
Quickly snap on the cap
on film canister.
Quickly put the canister into the launcher.
Make sure two partners are standing on the other side.
Once the launcher fires, let the two partners quickly mark the place with tape
Partner one marks where it landed not where it jumps then lands
Partner two writes the numbered trial and the temperature we were using
Repeat procedures for the 100 degrees trial three times.
Go and ask teacher to heat the kettle to 2000 and bring it over
Have teacher fill syringe to 20 ml
Teacher will squirt hot water into the film canister
Student will quickly place alka-seltzer tablet into the film canister
Teacher will quickly snap cap on the film cani
PLEASE BE WARNED :
THE EXTREMELY HOT WATER WILL EXPLODE QUICKLY, AND IS VERY HOT. LET ADULTS HANDLE IT!
Tali

9. Procedure Continued...
18. Partner one will go over to the place where cap landed and will mark where it landed, do not ark the place it jumped to.
19.Partner two will write the numbered trial and the temperature we were using
20. Repeat the procedures three times
21. Two partners will measure one partner will stay where the tape is which is where the place the cap landed to let the people know where to go
22. Write down measurements.
23. You are finished with this experiment! Great job!

12. Conclusion
The cold water did not make the canister explode quickly but made the cap go farther, and the hot water made the cap explode faster but did not shoot as far as the cold water.
Kaya

13. Other Questions
We spilled water during the times when we were putting the water inside the film canister in the experiment, so what would happen if we did the experiment again and did the exact measurements without spilling?
Why did the cap go farther when the water was colder?
How could we measure more exact?
If we were to launch even colder water, what would happen?
How could we control more variables?
What made the cap explode faster when we used extremely hot water?
