Experiment 3: The Perfect Bottle Flip
Experiment 3: The Perfect Bottle Flip
Watch the video about the Science behind the perfect bottle flip:
What you will need (this is called apparatus):
- 500 ml water bottle
- Measuring jug
- Tap water
- Pencil
- Ruler
- Paper
Results Table
| Volume of water | Tally of successful flips | Total |
|---|---|---|
| No water | ||
| 1/8 full | ||
| 2/8 full | ||
| 3/8 full | ||
| 4/8 full | ||
| 5/8 full | ||
| 6/8 full | ||
| 7/8 full | ||
| Full bottle |
Method
- Start with an empty water bottle
- Flip the bottle 20 times
- Record how many successful flips (bottle lands upright) you get in that time in the results table (you may need to print this off or draw your own with a pencil and ruler)
- Repeat steps 1 to 3 for the other volume (1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8 and a full bottle)
Now answer these questions:
- What was the thing you changed in the experiment? (This is called the independent variable)
- What was the thing that you recorded? (This is called the dependant variable)
- Name one thing you kept the same in the experiment (This is called the control variable)
- Which volume did you find was the best for bottle flipping
