We have learnt about living things and how they're classified in our science topic. We discovered that Yeast (yes the very ingredient that's used in baking) is...ALIVE. It respires and produces Carbon Dioxide - just like us!
We investigated the best conditions for respiration:
- Using warm water only - pink balloon
- Using a warm water sugar solution - white balloon
- Using a cold water sugar solution - yellow balloon
- Using a boiling water sugar solution - red balloon
Can you identify the best conditions for respiration?
