We have been doing Valentine themed activities this week and finding out what the day means to the children.
In the science corner we’ve kept to our theme to help us explore what happens when we put paper into water. We learned new vocabulary and discussed hypothesis.
We tried to guess what would happen when we put our folded hearts into water…there were lots of fabulous theories; “it’ll change colour”, “it’ll explode”, “it’ll sink”, “ it’ll get sugary, break apart”
The paper opened back up into a heart shape. We discussed why this happened – the paper absorbed the water causing the fibres in to paper to expand and push the paper apart. One child asked if there was more water would it sink. So we decided to find out and added a bowl that was deeper. Again we tried to guess what would happen. “It’ll sink” “it’ll float” “it’ll make waves”
Again the paper opened up “it’s opened up because we drop it in” one child exclaimed. Another child agreed saying “yes because we put it into the wet”.
The children continued to explore this for the rest of the morning.
The children were exploring different textures in the water tray today. We had some gooey red jelly and bicarbonate of soda fizzy ice as well as some fluffy frozen shaving foam.
The children loved feeling the different textures. They were able to use great descriptive words. They could see the bicarbonate ‘bubble’ when it came in contact with the jelly. The ice was SO cold and the shaving foam was like ‘snow’. Then one child said “it’s a big iceberg!” We all watched the iceberg float around our jelly sea before it slowly melted.
This morning the children set up an experiment to explore the effects different materials would have on ice “It’s cold” .
They added room temperature water, salt and bicarbonate of soda to separate bowls of ice and guessed what would happen. “It melts with salt because one day my Mum put salt on ice and it melt so fast” .
We used counters to record what we thought, “soda will melt”.
The children watched and waited to see what would happen “it’s melting and filling up, it might go over”
The children used descriptive language to explain what they saw “the purple one is bumpy” and “The green one is smooth”.
The water melted the ice fastest today but the salt was a close second.
