Fizzing volcanoes, balloon gas and colour chemistry for curious OSHC scientists.
Four weeks of hands-on test-tube science. Children predict, test and record reactions — including the classic vinegar-and-bicarb volcano and the balloon gas extension — with MTOP and NQF links throughout.
Everything you need to run this pack — print, laminate and go.
Start with Week 1, then add the next weeks as you go — each one builds on the last, so learning keeps flowing.
Lab safety boot camp
Children co-create lab rules and practise wearing goggles.
Test tube volcanoes
Add vinegar to bicarb soda in test tubes and watch the lava fizz.
Prediction charts
Predict and graph which mix makes the biggest eruption.
Outcomes
Don't forget weeks 2, 3 & 4 — each week builds on the last.
Balloon gas trap
Bicarb in the balloon, vinegar in the test tube — tip and watch the balloon fill with gas.
Bigger balloon challenge
Teams change one amount to grow the biggest balloon.
Science explainer videos
Children film a short explainer of their experiment.
Outcomes
Don't forget weeks 3 & 4 — each week builds on the last.
Rainbow test tubes
Mix primary colours in test tubes to make a rainbow rack.
Cabbage indicator lab
Test kitchen liquids with red cabbage juice to find acids and bases.
Results journals
Record experiments with drawings, colours and labels.
Outcomes
Don't forget week 4 — each week builds on the last.
Fair stall planning
Groups pick an experiment and plan their stall.
Science fair demos
Children demonstrate experiments to visitors.
Lab certificates
Children receive scientist certificates and reflect.
