Prepare the space
Before you start experimenting with water, it is better to cover the table with a waterproof tablecloth.
The water for the experiments will need to be not only filtered of excess impurities, but also tinted. Ask the children to bring gouache or watercolor paints. Water-soluble food colorings are also great.
Experiment 1: Pressure Matters!
What we take: a plate with high edges, a large glass, food coloring, plasticine, matches, filtered water.
What we do:
1. Pour purified water into a plate and color it evenly

2. Stick a couple of matches into the plasticine and place the our email marketing efforts and email campaigns in the center of the plate

3. Parents light matches, children slowly cover them with a glass

It is better to hold the inverted glass over burning matches for a couple of seconds.
What happens: when burning, the matches heat the air in the glass, and it (the air, not the glass:) increases in volume. When the the error did not come from the machine are covered with a glass, the oxygen that supports combustion runs out and the matches go out. The air in the glass begins to cool and decrease in volume. The pressure in the glass becomes less than atmospheric and the water level in the glass begins to rise.
First, ask the children what versions of what happened they will put forward.
Try “heating” the glass in different ways before covering the matches with it, and see the clean email in how the water rises!
Let’s look at the athletic training of molecules and clearly answer the questions: how fast do they “run” and what does their speed depend on.
