Experiments in elementary school with air and water

• They pose together with the children in the primary school open the bowl of water in front of you. Now a child dips the drinking glass into the water with the opening facing down. It is important that the drinking glass is held straight and that your student does not wobble.
• Have the children watch what is happening. During the experiment, ask the children what is now in the jar. They know that there is air in the glass and there is no room for water when the drinking glass is dipped straight down.

• Now your student can slowly tip the drinking glass to the side under water. Ask the children what happens if the glass is tilted. Exactly! Water runs into it.
• If, in the experiment, the glass is just immersed under water, the water is pushed down because there is air in the glass. If you tilt the glass, bubbles rise and the water can run into the glass because the air escapes.
• A very long time ago people used this method with a diving bell to use the air in the water under the bell, to breathe underwater or to look for something.


Can you feel air? - Simple experiments with children

To explain to children that you can feel air, you can do very simple things with them ...

Build a pillow out of air in elementary school

• You and the students inflate the balloons a little halfway. Then put this in the trash bag and tie it up. Make sure that the balloons have enough space and can lie in a square.
• Now put the garbage bag down and the board on top.
• During the experiment, ask the pupils from elementary school how many children can stand on it and what will happen. Are the balloons bursting or is the air carrying heavy weights?
• Now help your students move up. Other students can hold the board. It's going to be a shaky thing so the kids should be careful. Who dares to climb? With four balloons in the garbage bag, four children can try to be carried through the air on the board at the same time.
• The air is trapped and the balloons are only half full, so they don't burst, just flattened. The air in the balloons is compressed and presses against the rubber skin of the balloons. So the air can carry the children if they keep their balance well.
• But you can also build an air cushion with a sheet on which a child can lie without any problems.
• Several balloons are put into the bed sheet and then it is put down. Now a student can very carefully lie down on it. It's comfortable and can take the weight.
• Bicycle tires prove that trapped air is very strong and can lift weights. In the bicycle tire, the air is held in place by a tube and solid rubber. This is how the bike tours succeed over hill and dale.
