Anyone can easily do fun experiments using theories of physics, chemistry and life sciences. Materials will require some easy- simple equipment and some chemicals. They can buy them from big city stores and make some of the equipment themselves. And if you do not have the money to worry! The school laboratory is there. Your teacher would be happy to extend a helping hand to you when he knows about your need. In recess time one by one you can go to the laboratory one day at a time and do a fun experiments. This time let’s talk about some simple yet wonderful science experiments. They are as fun, enjoyable as they are educational. In this blog you will find lots of experiments.
1. Silver Tree
One the name of the silver tree does not make one think that a sculptor has carved a silver rod and made a silver tree as a symbol of his perfect workmanship. No, you may not be an artist or a sculptor. You are a science lover, ordinary student only. You can easily make a silver tree without being an artist or a sculptor, of course, if you can collect the materials for this test, he can buy it or go to the school laboratory. Below is a list of all the materials needed to make a silver tree.
A large and earthenware glass tube (test tube), a test tube stand, a six-bar glass rod, a crystal of approximately silver nitrate compound, half an ounce of approximately distilled water and a piece of clean copper wire.
First in the middle of the sixth glass rod. Tie one end of the clean copper wire well. Wash and dry the inside and outside of the test tube. Add half a gram of silver nitrate compound and pour half an ounce of distilled water in it. You will see that the crystals of silver nitrate have completely dissolved in the distilled water. Now place the glass rod on the test face of the tube in such a way that most of the clean copper wire is immersed in the silver nitrate solution inside the tube. Once this is done, place the test tube in a test tube stand. Leave the test tube stationary on the stand for at least two hours. Do not move in the tube at all.
After a couple of hours, you will see that six particles of silver or silver have come out of the silver nitrate compound on the copper wire and have come together to form a beautiful tree. And that’s inside the test tube. Yes, that is the silver tree. Big beautiful to look at.
2. Led Tree
You can make lead trees like silver. Of course in that case the materials would be different.
A clean glass vial, a clean zinc rod, a glass rod, some clay yarn, a glass of approximately six to seven grams of lead acetate compound, a little distilled water and a small amount of mild acetic acid.
First cleanse the stomach. Pour six to seven grams of lead acetate into the glass bottle. Then in Bethel. Pour the distilled water in such a way that half of the bottle is filled with water. Keep drawing the bottle. After a while, the crystals of lead acetate will dissolve in distilled water. The solution will not be transparent then. There will be a feeling of exhaustion. A small amount of dilute acetic acid is added to the solution in the bottle to make the whipped cream clear. The solution will become clear as soon as the acid is poured.
Then place the glass rod on the face of the glass bottle. Tie a knot with one end of the thread in the middle of the glass rod. Keep tied the clean zinc rod to the other end of the yarn and immerse it in the solution in the bottle. So that three-quarters of the zinc rod is immersed in the solution.
If you leave the vial in one place for six to seven hours without moving it, you will see that the part of the zinc rod that is immersed in the betel solution has a beautiful lead tree with fern-like stalks on it. Needless to say, fine lead particles deviate from lead acetate compounds and accumulate on zinc bars to form lead trees.
3. Ferrocyanide Fern
The tests are almost the same, the materials are just different.
gelatin, potassium ferranide, copper sulphate (tu) and sugar. Also a glass jar. And a small amount of common salt.
Mix two parts copper sulphate or one part moist sugar with mulberry powder and make some dry pills. Dissolve one ounce of gelatin in one ounce of hot water. Then a glue like jelly, while the glue is still hot, mix one ounce of fine potassium ferricanide powder and half an ounce of ordinary salt powder with a little water. Stir this mixture with the sticky substance like jelly made earlier.
Pour this mixture into a glass jar and drop the previously made pills in it before it freezes. After a while you will be surprised to see that the mixture will get a brown color and he broad-leaved fern-like copper has turned into a ferrocyanide tree-like object. This is called ‘ferrocyanide tree’. Imagine what it would look like.
