Bottle Rocket
Today we are going to participate in a science experiment which is linked to the Australian Science Curriculum.
Year 2 Science Understanding – Chemical Sciences: different materials can be combined, including by mixing for a particular purpose (ACSSU031): http://www.australiancurriculum.edu.au/Science/Curriculum/F-10#level=2investigating the effects of mixing materials together.

Let’s make a bottle rocket:

What we need:

Safety Goggles
A 600ml pop-top type bottle
White vinegar
Bi-carbonate of soda
Paper towel
Plastic cup

How to make it:
  1. Put on safety goggles
  2. Pour white vinegar into the plastic bottle and a third fill bottle.
  3. Place a tablespoon of bi-carbonate soda onto one sheet of the paper towel.
  4. Quickly replace top on bottle.
  5. Turn bottle upside down and place in plastic cup.
  6. Stand back and see what happens.

What is happening to the white vinegar and bi-carbonate soda?
Use the Predict, Observe and Explain table to document your science experiment.

Discussion:

  • Talk to students about past learning and chemical science experiences.
  • Discuss how the ingredients and equipment are to be used.
  • Discuss safety requirements.
  • Encourage students to participate in all aspects of learning.
  • Watch a YouTube video on the bottle rocket experiment.

Engage students in a discussion drawing on their prior knowledge, e.g. when they made a volcano in Year 1.
(Refer to Year 1 Science Curriculum http://www.australiancurriculum.edu.au/Science/Curriculum/F-10#level=1)
Discuss the properties of the chemical used.
