Elliot and the Surfing Scientist: Get Blown Away With This Air Experiment

SUBJECTS:  Science

YEARS:  5–6


Substances exist in different states depending on the temperature.

In this science experiment you can watch the Surfing Scientist has a popping good time as he demonstrates this phenomenon.

Don't forget to block your ears!


Things to think about

  1. 1.Do you know the temperature that water boils at? What happens to the water at that temperature? Imagine if water boiled at room temperature.
  2. 2.What is the name of the substance that is added to the large water bottle? Is it a solid, liquid or gas? Notice the safety equipment worn by the Surfing Scientist and Elliot. Can you name the three items they are using?
  3. 3.What did you observe happening to the balloon after it was secured to the top of the water bottle? What was inside the balloon? The clip demonstrated some of the different properties of liquids and gases. Can you name two?
  4. 4.

    Do an internet search to discover the boiling point for liquid nitrogen. Describe to a friend how the boiling point of nitrogen relates to the balloon pop experiment. Explain why the experiment can be done at room temperature.
