This week at Tillys Fern Bay we are experimenting and investigating all week as we explore National Science Week. This year the theme is protecting our oceans. For our first experiment this morning we discussed how plastics and styrofoam are dangerous to our oceans as the sea animals eat them. We hypothesised that starch packing chips are better for our ocean environment than styrofoam balls. We then measured our two cups of water and we added some of each to the two cups and stirred them up and watched what happened.
“Nothing happened to the balls” stated Jackson.
“The other ones are disappearing” said Alice.
“Well they aren’t disappearing, they are dissolving in the water. What do you think a turtle would do with the other balls?”
“It would eat them” said Jack.
We then read the story Ada Twist Scientist and discussed the importance of asking why and experimenting to learn about the world around us.
We then transitioned to the craft table where we explored some exploding colour changing test tubes. We used pipettes to add different coloured vinegar then added coloured bicarbonate to the top which caused the solution to bubble up and change colour. Through this experiment the children explored mixing different amounts and colours to see what would happen.
Nash explored some engineering using the cog blocks exploring and experimenting with cause and effect.
