Canister Experiment
You will need (Materials)
- One empty 35mm plastic canister and lid.
- One fizzing aspirin tablet
- Water
What to do (Method)
- Head outside.
- Break the aspirin tablet in half.
- Remove the lid from the canister and put a teaspoon (5 ml) of water into the canister.
Do the next 2 steps quickly - Drop the tablet half into the canister and snap the cap onto the canister (make sure that it snaps on tightly.)
- Quickly put the canister on the ground CAP SIDE DOWN and STEP BACK at least 2 metres.
- Stand back and watch!
Variables
We were going to investigate to see if the amount of the tablet will cause the canister to go higher.
What do I think will happen? (Hypothesis)
I think that when we put in one tablet the canister will not go that high but will still go high.
I think that when we put in 1 ½ tablets the canister will go higher than one whole tablet.
What happens (Results)
Variable

What can you see? Hear? Smell?

1 Tablet.

I heard the canister pop, and saw the canister go flying off
of the lid. |
1 ½ Tablets.
|
I did not hear the canister pop this time but I saw the
canister go flying off of the lid higher than the one tablet, the canister lid was very sticky. |
Conclusion
I noticed that using 1 ½ tablets was better than using 1 tablet.
The 1 tablet did not go as high as I thought.
The 1 tablet did not go as high as I thought.
