7Hello everybody.
Last week we started the topic experiments. The first experiment we did is to let unfold a paper flower in the water. The second experiment was the floating candle . The third experiment was making slime.
We asked ourselfes different questions.
For example ; What opens the paper flower ? When we did the experiment outside a student answered ; ¨The wind .¨But inside the flower openend as well . Magic ???
What happens if we put a bigger flower? does it open faster or slower ?
The floating candle experiment was very interesting as well.
1 put some coloured water in a plate
2 strike a match and lighten the candle
3 put the candle in the plate
3 Put carefully a jar over the candle.
The result: the water is rising and the candle is floating . Why ????
The candle stops burning because of a lack of oxygen. And because it uses the oxygen it causes a vacuum effect that makes the water rise and the candle float.
We had loads of fun !!
