Children are always curious about the environment in which they live. ExcitingExperiments for childrenarouse the little ones' interest and get them excited about science. With physical and chemical experiments, the children always learn something new in an interesting way. Read on to find fun and easy DIY projects with instructions for experimenting with kids.
In kindergarten, at school or even at home, children can learn physics, chemistry and technology in a playful way using different methodsTry itinspire. This makes learning easier and more interesting for them. Dangerous or toxic substances for children's experiments should perhaps be avoided or secured with appropriate safety measures. For chemical experiments, for example, safety glasses and gloves provide adequate protection.
Make your own lava lamp
Non-toxic experiments are suitable for children of all ages - from toddlers in kindergarten to older students. Colorful lava lamps, for example, are with theminteresting effectsvery popular among children and adults, so below we present a simple guide on how to make a lava lamp with the children.
Make your own lava lamp – first steps
For this experiment you will need a tall clear plastic or glass bottle, cooking oil, water, food coloring of your choice and either effervescent tablets or salt. First, fill the bottle a little more than halfway with cooking oil. Then add water until the bottle is almost full. The first chemical reaction can already be observed - since the oil has a lower density than the water, it floats on top.
Instructions
Next, add 10-12 drops of a popular food coloring. You can see that the paint mixes with the water and not with the oil because it has a similar density to the water. Next, break the effervescent tablet into smaller pieces.
Chemistry for children – the finished lava lamp
Lastly, tip some salt or drop a piece of the effervescent tablet and watch the magic happen. These substances are more dense than oil and water and therefore sink to the bottom of the bottle, taking droplets of oil with them on the way down. After dissolving in the water, the “entrained” oil drops rise back up and create the interesting lava effect.
You can find a homemade lava lamp in a glass container and two other children's experiments in the video:
Color flowers with food coloring
Flowers can be colored colorfully using food coloring. Since they absorb the liquid in which they stand through the stem, their flowers are colored in the corresponding color. You can also get the effect with green plants, such as romaine lettuce, although the colors don't look as strong.
Popular experiments for children
For this children's experiment you will need white flowers of your choice, food coloring and glasses or vases. The containers are filled with water and the colors are dissolved in the water. Then place the flowers in the vase with the colored liquid and watch the color change over the following days.
Chemical children's experiments - the colorful rain cloud
Some children's experiments do not necessarily result in learning something new. From time to time, you can do interesting projects with your children that are more likely to develop their imagination. We present a suitable idea with this colorful rain cloud.
Rain cloud in a glass – materials and instructions
Preparation for this children's experiment begins with dissolving food coloring in small cups of water. A larger glass, a glass container or a transparent vase is filled halfway with water and the rest with shaving cream.
Create colorful rain in a glass with a pipette
As can be seen visually, the foam looks like a cloud. Its lower density ensures that it stays on the surface of the water. To get the effect of rain, the colored water should be dripped onto the cloud using a pipette.
Experiments with children in the kitchen
In the end you get a rain cloud of any color. You can do this experiment in your own kitchen with the children and look at the beautiful color effects together.
Outdoor Experiment
You can also carry out experiments with children outdoors if the weather is nice. If you have a sandpit in the garden, the child can make a small volcano themselves and observe a chemical reaction.
The volcano made of sand
The sand volcano should be formed around a container until the container can no longer be seen. Don't forget to leave some space in the core of the volcano. Then add baking soda and pour vinegar. The chemical reaction between the two causes the volcano to erupt.
Children's experiments with water and paper
Most children are fascinated by water experiments. With three glasses, food coloring and paper towels, they can see how the water moves from one glass to the other on its own! For the children, the experiment looks like magic, but it also has a physical explanation.
Physics for children – the magical water pipe
Two glasses are filled with colored water and the third is placed empty in the middle. Two pieces of paper towels are rolled and placed over the jars as shown. The glass in the middle is filled with water and in the end the three glasses are equally full. The secret: the paper consists of closely spaced fibers and cavities in between. When the kitchen towel gets wet, it acts as a hose, directing water from one jar to the other. The cause is the so-called “adhesion force” between the cavities and the liquid.
Children's experiments in kindergarten or school
An interesting experiment can be carried out with water, a freezer bag and some sharp colored pencils. Fill half of the bag with water and close the ziplock. The children should get the colored pencils through the filled part of the bag.
A perforated bag with water that doesn't leak
Instead of bursting the bag, the sharp colored pencils appear on the other side without spilling the water. This water experiment for students is a good idea for a lesson on polymers.
Experiments for children with air - necessary materials for a balloon rocket
Children's experiments can also be carried out using simple materials that everyone has at home. She makes a flying rocket using a string, a balloon, a drinking straw and adhesive tape.
Children's experiments at home or in nature
Place the drinking straw on the string and stretch the string across the room. Then inflate the balloon, hold the mouthpiece in your hand and attach the balloon to the drinking straw with some adhesive tape. Then let the balloon rocket fly and watch it with the child.
