The great thing is that all the experiments described below are carried out at home, and watching them is really exciting, even when you know 100% what the result will be. Well, if you demonstrate some of these experiences to your child, then for a long time you will remain in his imagination as a kind of creature from a fairy tale that owns ancient magic. Well, are you ready? Then let's go!
Experience 1: Flying tea bags
What you need: matches, scissors, tea bags.
How to make: tea bags need to be opened, the thread with the label cut off, and the tea leaves pour out of the bags. Then it remains only to put the empty bags on the table (in the form of factory pipes) and set fire.
What will happen: if you let the bags burn out almost to the end, you can see how warm air carries the burning bags up. If you are just starting to do experiments at home, this experiment will be a great choice, becauseit is very easy to carry it out, and the flying remains of the bags even look beautiful in their own way.
Experiment number 2. Glowing squash and cucumbers
What you need: pickled and fresh cucumbers, squash, wires, access to 220 V, copper wire.
How to make: First you need to attach the copper wire to the wire. Next, you need to stick the ends of the wire into a fresh cucumber and connect the wire to the network. Then change the fresh cucumber to the squash and do the same with it. Now you need to repeat all these operations with pickles.
What happens: In the case of a fresh cucumber, you will see bubbling juice near the holes formed and a light smoke coming from the cucumber. But as soon as you change the cucumber for patisson, it will begin to glow from the inside. A pickled cucumber will not only glow, but also move. Similar experiments at home prove that the amount of s alt in an object is directly proportional to its electrical conductivity.
Experience number 3. How to cut with scissors… glass
What you will need: an aquarium filled with water, scissors and thin glass.
How to make: a sheet of thin glass must be immersed in an aquarium of water, holding it with one hand. Then dip your hand with scissors into the water and start to slowly cut the glass.
What will happen: in water, due to the capillary effect, the glass becomes much more pliable, and therefore it can be cut very easily, with only a slight effort. And the linethe cut will turn out to be very neat, and not “torn”. However, the experiments at home do not end there.
Experiment number 4. Heating iodine and starch
What you need: burner, test tube, starch, water, iodine.
How to do: This experience is often included in various collections such as "Chemical experiments at home for children." It will be not only interesting, but also useful to observe the reaction of schoolchildren. Pour a pinch of starch into a test tube, and then add water. Next, add a little iodine, light the burner and slowly heat the mixture. Then the test tube must be cooled by placing it in a glass of cold water.
What happens: when heated, the solution loses its dark blue color, but when cooled, it returns again.
These and many other interesting experiments at home you can do at any time. Experiment, try, but most importantly - do not forget about your own safety!
