1. Experiment: Cold water and warm water

For this experiment you will need three bowls:

• Fill up bowl A with cold water. You can melt a few ice cubes beforehand if you like.
• Fill up bowl B with semi-warm water. The temperature of the water from the tab is perfectly fine.
• Fill up bowl C with hot water. Please take care that the water is not too hot. You should not burn yourself if you put your hand into the water.



Ask someone else to do the experiment for you. However, do not tell them about the different temperatures of the water.
