Miss Discombe’s class have been experimenting to see what cress needs to grow.
We planted some seeds with soil, sun and water. We thought these would grow – they were our ‘control’. We were right, they did.
We also planted some without one ‘variable’ – without sun, or without water, or without soil.
The ones with no water didn’t grow at all.
The ones with no soil grew a tiny bit but hardly at all.
The ones with no sun grew tall but were yellow and unhealthy looking. We wouldn’t eat them!
