Magic

Today we made a fun and magical experiment. We tried it last week but did not succeed very well, but after some expert advice from Hans Persson we dared to try again. Shame not to give up! 

What did we do?

Patrick poured baking soda and vinegar in a jug.

Paulina "poured" over a glass. No liquid may come down. Hocus pocus!

Then Johan turns out the light with "nothing".

Solid or liquid?

We have over a period worked extensively laboratory and we talked about the substance in different physical state. As a fun end I showed the class a little experiment.

Mix corn starch or potato starch in some water and try to figure out if it is in solid or liquid form.

The children became very enthusiastic and appreciated the experiment. I think many of them also have shown their new "party trick" at home.
