Scientific Experiments You Can Do at Home – Webtekno

Experiments are scientific experiments that appeal to people of all ages, young and old alike. showing a fact are methods. We’ve all done or tried to do an experiment at least once in our lives.

This method, which further triggers people’s sense of curiosity, actually one of the most effective learning tools is one. If you’re bored at home or want to spend quality time with your child, it’s worth taking a look at this list! We are sure that this list will increase your interest in science…

First, let’s make a plastic from milk, for example!

What you need:

• A glass of milk
• 4 teaspoons white vinegar
• a bowl
• a strainer

So, let’s see how it’s done:

• First, pour the milk into a small pot and heat it until it is hot (be careful not to boil the milk at this stage).
• Then pour the milk into the bowl you removed.
• Add white vinegar to the milk and mix with a spoon.
• Now we come to the most fun part… Strain the milk and collect the remaining balls in the filter.
• Wait for the plastic you created to cool and rinse it in water after it cools.

How it happened: What you’re actually making is a type of cheese called “casein”. These small lumps appear when the protein in the milk reacts with the acid in the vinegar; This event is also known as the polymerization reaction. So, what you have made is not exactly real plastic, but its texture makes you feel like plastic.

Making crystals from eggshells can add a special touch to your home:

What you need:

• Clean egg shells in any quantity you desire
• This
• Soluble solids: Table salt, rock salt, sugar, baking soda, sea salt or borax
• Small heat-resistant containers
• Spoon
• food coloring
• Egg carton or small muffin cups

Don’t be afraid of the ingredients required, it’s very simple to make:

• First of all, you need to empty the inside of the egg, by breaking it as close to the narrow end of the egg as possible.
• Clean the egg shells with hot water.
• Then, you need to remove the thin membrane inside the egg by hand, so washing the egg shell in hot water is very important for this process because it will help remove the membrane.
• Once you’ve removed all the membrane, place the eggshells into the egg carton or muffin cups.
• Add half a cup of water to your small heat-resistant bowl (small cups will do for this experiment).
• Add about 1/4 of your soluble solids to the water.
• Continue adding your solids in a controlled manner and stir until the water becomes supersaturated.
• Add food coloring.
• Pour the solution you have prepared into the egg shells, but not excessively.
• While waiting for the water to evaporate, place the egg shells on a solid surface.
• And your crystals are ready!

How it happened: It means that the salts use the energy of hot water to help them dissolve until there is no space left between the molecules in the solution. As the solution cools, the water loses its energy and the crystals are forced to separate from the solution to become a solid again. As evaporation occurs slowly, the crystals begin to grow larger and larger, creating these beautiful decorations!

You can leave extraordinary notes to your lover, friend or child with the invisible writing experiment:

What you need:

• Lemon
• This
• Spoon
• a bowl
• Ear stick
• a white paper

How it is made:

• First, cut the lemon in half and squeeze its juice into a bowl.
• Add a few drops of water into the lemon juice and mix with a spoon.
• Then dip the ear swab into lemon juice and write whatever you want on white paper.
• Don’t forget to tell the person you left the note to bring the white paper closer to a light source…

How it happened: When lemon juice gets hot, it will oxidize and as a result, the writings will look like they are rusted. Moreover, you do not need to try this with just lemon, it is acidic like lemon; You can also make it using orange, onion or vinegar. However, now there is no need to make a fuss with onion or vinegar, we think the best thing is to make it with orange or lemon!

Did you know that water also has surface tension? Come experience this first hand:

What you need:

• Plate
• This
• Black pepper
• Tea spoon
• Some detergent

How it is made:

• Take the plate and fill it with some water.
• Add some black pepper to the water-filled plate.
• Pour a few drops of detergent into the middle of the water.

How it happened: Even though you cannot see it on the surface of the water, there is a very thin membrane formed due to surface tension. The detergent ruptures this membrane, causing a tear on the surface of the liquid. This tearing causes the appearance of black peppers escaping to the side.

Another egg experiment, don’t worry, this one is much simpler than the other one!

What you need:

• Egg
• Glass bottle
• Napkin or newspaper
• Matches or lighter

How it is made:

• Boil the egg and peel it thoroughly after boiling.
• Burn a piece of newspaper or tissue and throw it into the glass bottle.
• Without wasting any time, place the egg right at the end of the glass bottle.
• As time passes, you will see that the bottle literally eats the egg.

So, if you are wondering how this can happen: When the egg was first placed in the mouth of the bottle, the internal and external pressures were equal. However, when you burned paper inside and threw it inside, the burning continued until the oxygen ran out and the egg could not get air from the outside due to the high open air pressure. Since the pressure outside the bottle was greater than the pressure inside, it looked just like the bottle had eaten the egg.
