Soda - Sugar Content (Float and Sink)

This was a very interesting experiment conducted in my Year 2 Science class.

Hypothesis: Why do some cans sink while others float?

Materials:
- Four different soda cans - two being diet. All being equal size and volume.
- One large transparent container
- Water

Method:
1. Fill the container with water
2. Place a regular soda can in the water
3. Observe and discuss
4. Place a diet can in the water
5. Observe and discuss
6. Repeat with other two cans

Findings:
The sugar content in a regular can on soft drink is higher than that of a diet can, therefore leading to differing densities. The regular soda cans will sink whilst the diet cans will float.

 

 

Sugar was shown to demonstrate the sugar content in the soda can.
