Here we present different types of activities, that children can play, depending on what do you intend them to learn or develop.
“Let’s play to be scientists”
These games are ideal for curious children, but should always be supervised by an adult. Be especially careful with chemicals, heat and sharp objects.
“The map of the stars”:
A map of stars visible from our population, to identify their names and their situation.Put a poster in a window where you can see the sky, make holes to match the stars seen through the window. Turn off the light and focus the cardboard from behind with a flashlight.
For children over 9 years. You can engage the number of children you want, with adult supervision. For this game you need: a glass and one or two coins.Place the children in a semicircle. Put the glass near the edge of a table. Place a large coin horizontally on the edge of the table that is closest to who is doing the show.
Blow the coin over the glass. It will jump. (Due to the Bernoulli effect)
Then take the kids conclusions. Trying all participants to perform the experiment
* Bernoulli Effect is when a stream of rapidly moving air produces a low voltage area around it. By blowing strongly over the surface of the coin, it causes a lower atmospheric pressure than there is in the bottom of it. The higher air pressure beneath the currency pushes this up.
“What materials retain heat?”
For children older than 9 yearsNeeded for this educational game observation: metallic objects, boiling water, wool clothing and ice.We again remind scientists that these games should always be supervised by an adult.
Each child will place metal objects into the container with boiling water. After a while they will remove carefully to avoid burns.
Half of the children will wrap the metal object in the garment of wool, and the rest will leave them without wrap, in contact with air.
After verifying what happened, we will discuss about the reasons why some items were cooled before others. Let the children give their views freely. Then, the adult will give the right answer.
All children take an equal-sized ice, wrap it in a woolen garment, the other will leave the ice in contact with air.
Observe what happens in both cases, and then will discuss the issue.
Then the adult asks, “Why wool keep us warm?”, allowing each child to answer freely, then exchange ideas. The adult will guide the children to the conclusion that.
Wool retains both high temperature and low. So the wool gives no heat, but it is a good thermal insulator.
For children over 10 years
For this game it is needed for each group of participants: a small bottle of soda, a balloon, a large container and water.
The adult will prepare the experience this way:
Place the empty bottles of soda in the freezer for a few minutes. Then removed from the freezer and give one to each of the groups.
The children in each group put the balloon on the tip of the bottle. Then put the bottles in the large bowl. The adult pour hot water over them.
The groups observe what happens and will discuss it. The questions to ask an adult for discussion are: “What happens to the balloon?” And “Why?”
Then remove the bottle from the water and see what happens.
Once the results are compared to reach the conclusion that heat expands gases.
