Is it that time of year again where you’ve got to teach solids, liquids and gases? A DVD just won’t cut it? Look no further than popping rockets!! This fun and engaging experiment will enthuse even the most reluctant learners.
Encourage your class to predict, measure and record all during this simple to set up experiment. Why not try changing how much water you put into the pot to see if this changes the time it takes for the gas to build up in the bottle and explode!
Put some water in the canister until it is about a third full. Stick the fizzy tablet to the inside of the lid using blue tac.
The pressure of the gas has built-up and it’s too great for the lid to stay on the canister.
Extension activities could be running competitions to seeing whose rocket goes the highest or which surface is best to launch your rockets off.
Above all else this activity is fun whilst learning hands on key scientific facts.
