Experiments with water for children

In Ukraine, the quarantine continues for a third week. And one of the main questions of staying at home, what to do with children. And if your imagination in organizing children’s leisure time is running out, it’s time to come up with something new. Since our field is water, we will tell you about what simple and interesting experiments you can conduct with children to diversify your home leisure time.

1. Mixing Colors

When you mix different colors, there is a spontaneous process of mixing substances due to thermal motion. It is called diffusion.

What we will need?

  • water;
  • containers (for example, disposable plastic cups);
  • watercolors.
  • Syringe, dropper or spoon.

Technique of performance

This is probably the easiest experiment that you can conduct at home with children. You pour equal amounts of water into three containers and color the water with a paintbrush in three basic colors – yellow, blue, and red.

By simply mixing the colors in the empty cups you and your child can get:

  • orange (yellow + red);
  • green (blue + yellow);
  • purple (blue + red);
  • you can also dilute the colors with water or white paint and watch the brightness change.

baking soda

This experiment can also be repeated on paper.

2. Running colors

This experiment, like the previous one, shows how diffusion works.

What will be needed?

  • water;
  • Watercolor or other water-soluble paints
  • containers;
  • Gauze or wet wipes.
Implementation experiment

Implementation of the experiment

In three glasses you dilute different colors, for example, as in the previous experiment yellow, blue and red. But you can use other colors and sequences. Then pour clean water into the other three cups and place them alternately in a circle or in a straight line.

After that, you need to put pieces of bandage or a damp cloth in pairs into each glass of paint and glass of water in pairs. If you leave this design for a few hours, you can observe how the water in the cups of clear water will turn a color that is a mixture of the two colors next to each other. This is also the effect of diffusion.

3. How an empty bottle can inflate a balloon?

In this experiment, we will see how temperature differences affect gases. See how the air around us can expand and contract at different temperatures. The water in this case will act as a heater and a cooler.

container Then

What will be needed?

  • Two hollow containers;
  • room water and hot water;
  • ice;
  • boiling water;
  • 0.5 L plastic bottle;
  • inflatable balloon.

The realization of the experiment

Place an inflatable balloon on the neck of the bottle and fill the first container with water at room temperature and throw a few pieces of ice into it, and pour hot water into the second.

After that, you need to drop the bottle into a container of hot water, which will cause the balloon to inflate due to the expansion of air inside the bottle. Then the bottle should be placed in cold water with ice and the ball will deflate.

4. Experiment with red cabbage

In chemical laboratories, there are special substances – indicators, which allow you to determine whether the environment is acidic or alkaline. It turns out that the simplest indicator can be bought in a vegetable store.

What will be needed?

  • water;
  • The juice squeezed from the red cabbage in the container;
  • baking soda;
  • sugar;
  • vinegar;
  • squeezed juice of one lemon;
  • 5 transparent cups;
  • teaspoon and tablespoon;
  • a pipette (not necessary);
  • 5 wooden sticks or a pencil.

6 AMAZING WATER TRICKS / Science Experiments/ Easy Experiments

Implementation of the experiment

To prepare, squeeze the juice from a quart of cabbage. To do this, you can simply whip it in a blender and pour the resulting liquid into a container.

glass container

Then yourself or with a child, fill five beakers with 20-30 ml of water and add reagents to each of them sequentially:

  1. ½ teaspoon of baking soda;
  2. 1 teaspoon sugar;
  3. do not add anything;
  4. 1 tablespoon of vinegar;
  5. squeeze the lemon;

Stir and bring liquid level in all cups to the same level.

Now let’s begin to determine the pH of the medium. This process can be fully entrusted to a child. In each cup you need to pipette or teaspoon put about the same amount of cabbage juice and stir with a wooden stick or pencil (you need to wash) and you will notice how it reacts to alkaline (soda), neutral (pure water, sugar) and acidic (lemon, vinegar) medium.

5. Rainbow of water and sugar

This beautiful experiment is based on the density of water solutions.

Implementation experiment

What we will need?

  • water;
  • sugar;
  • watercolors or any water-soluble paints;
  • pipette, syringe, or teaspoon;
  • a glass cylindrical container;
  • beakers.

Performing the experiment

If we’re going to make a classic rainbow, we’ll need six cups. Next, you need to pour about the same amount of water into them (fill by ⅓) and add paint of the desired color with a paintbrush to each cup. When the colors are dissolved, you need to add sugar in the containers with the colors one by one, taking into account that the first cup does not need sugar at all, the second cup 1 teaspoon, the third cup 2 teaspoons and so on.

container Then

After that, fill a syringe or pipette with a few milliliters of solution with the largest amount of sugar and pour it to the bottom of the glass container. Then we take a solution with a lower concentration and carefully leaning the test tube or syringe against the wall of the glass container we add dropwise. Repeat this procedure with the rest of the solutions. If the operation is done carefully enough, you will have a beautiful rainbow of colors.

6. How gases work

What will be needed?

  • water;
  • plasticine;
  • A few matches;
  • a glass or a small jar;
  • a container of water with low sides.

Implementing the experiment

  1. Place a piece of plasticine in the center of the water container;
  2. Pour 1 to 2 centimeters of water into it;
  3. Stick a few matches in the plasticine and light them;
  4. quickly cover matches and plasticine with a glass or jar.

You will be able to observe how simultaneously with the burning of the matches the water from the plate is drawn into the jar in the place of the burned oxygen.

7. Lava in a bottle

What will be needed?

  • sunflower oil;
  • water;
  • glass jar or bottle;
  • watercolor paints;
  • an instant pill (aspirin, fizzy vitamins, etc.).) or vinegar and baking soda.

The realization of the experience

  1. fill a clean, clear container with sunflower oil;
  2. Pour water on top;
  3. Add a little watercolor to water with a brush;
  4. drop an effervescent tablet or alternately add baking soda and vinegar into the container and watch the magic work.
