🔍 Reversible or Irreversible? Year 5 & 6 Investigate with a Zesty Twist🍋

Science in Action: Eagles and Ravens Explore Change

Today, our Eagles and Ravens (Year 5 & 6) children rolled up their sleeves for a hands-on science investigation into reversible and irreversible changes – and what better way to explore than by making delicious homemade lemonade!
Under the guidance of Mrs Williams and Mrs Jaeger, the children zested, grated and juiced lemons before adding water and sugar. This sparked lively discussions:
  • Which processes could be reversed?
  • What happens when sugar dissolves?
  • Can we recover sugar through evaporation?
After their scientific work, everyone enjoyed their refreshing drinks – and one child summed it up perfectly:
“Science was really fun today!”

Teacher Reflections

Mrs Williams shared:
“It was wonderful to see the children so engaged in practical science. They were asking brilliant questions and using scientific vocabulary confidently.”
Mrs Jaeger added:
“Making lemonade was a fantastic way to explore reversible and irreversible changes. The children loved investigating and tasting their results!”

STEM Sentence Starters

To help children talk scientifically, try these prompts:
  • I observed that…
  • This process is reversible because…
  • I think this is irreversible because…
  • When we added water, the sugar…

🔍 Did You Know?

  • Evaporation is a reversible change because water can turn into vapour and then back into liquid again.
  • Cooking an egg is irreversible – once the proteins change, they can’t go back to their original state!
  • Dissolving sugar in water is reversible – you can get the sugar back by evaporating the water.
