3rd Grade Being scientists.

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 !!
