Project Description

Kitchen Chemistry

A fun food workshop challenging you to think about everyday food in a whole new way. Experiment with a variety of food-related chemicals, and you even get to take home a bag of sweet, tongue-tingling sherbet!

  • Level: Suitable for Foundation to Year 2.

  • Duration: Available in a 60 or 90 minute format. We recommend a 90 minute format if budget and timetabling constraints allow.

  • Numbers: Each workshop can cater to a maximum of 30 children. However, smaller groups have better access to equipment and the facilitator.

  • State: VIC, NSW & QLD

Learning Outcomes

  • Every substance in the world is a chemical.

  • Yeast is a special kind of fungus that we use when baking. Yeast produces a gas called carbon dioxide that makes bread and cakes rise.

  • Some foods contain acids and some contain bases. You can test for them by using an indicator. Acids and bases neutralise each other when mixed together.

  • Chemical reactions produce new substances. If a gas is produced, lots of bubbles can be seen. If the gas is allowed to build up in a container, it can explode the container. Sometimes chemical reactions can produce heat, and other times they use heat.

  • Chemical reactions can be sped up or slowed down by adding other substances to the reaction.

  • The ‘fizzy’ sensation experienced when eating sherbet is the bubbles of gas produced by an acid-base reaction.

  • The acid in certain fruits can be used to generate electricity.

  • Milk contains water, protein, and tiny droplets of fat. All of these interact with detergent.

Activities

  • Students observe the respiration of yeast, evidenced by the production and capture of carbon dioxide.

  • Students use an indicator to identify an acid and a base. They observe the process of neutralisation by mixing an acid and base together.

  • Demonstration of a chemical reaction using kitchen chemicals that produce carbon dioxide gas.

  • Students perform a similar chemical reaction and observe what happens when the gas pressure is allowed to build up. They feel the temperature of the chemical reaction.

  • Demonstration of a chemical reaction that produces heat and light energy.

  • Make and eat sherbet, noting the ‘fizzy’ sensation produced by the chemical reaction.

90 minute workshops also include these activities:

  • Students observe how the acid in a citrus fruit can be used to generate electricity and power a device.

  • Students use food colouring to observe the effect of disrupting the surface tension of milk.

Fantastic birthday party for my 8 year old daughter. Antonia did an amazing job keeping 17 children engaged and entertained. Everyone that attended had a great time. Would definitely recommend.
