7 scientific experiments to do with children at home

With the holidays there, we will share with you 7 scientific experiments to do with the children at home! It will be a diversion for the whole family!

Hi, Moms and Dads! As the July school holidays are already here for most of the students in the country, we decided to bring, in collaboration with Twinkl, 7 tips of scientific experiments to do with children at home.

We have had numerous requests from moms who have followed our work since the beginning, the children have grown and now need another type of content and support network! Wait for us to have a lot of stuff coming out of the oven for you!!!

Today, we bring these scientific experiments, which in addition to superfun, are still a great opportunity to teach a little science to the children!

Everything you will need is very easy to find in the supermarket. You even have experience that doesn’t make a mess!

To make it easier, we also included the explanation of each of the experiments – at your child’s next science fair, you’ll even get some ideas of what he can build.

It’s like we always say: these moments will become cherished memories between parents and children, right? So choose one of the 7 scientific experiments, gather what you’ll need and get to work!#1 Hair Creepy – Static Electricity

The best thing about this scientific experiment is that children will be able to visualize something that is usually invisible: energy. In that case, static electricity.

This activity is great because it teaches about science with materials that are mega easy to achieve and without making dirt at home.

You’ll only need two things: a balloon and a piece of woolen clothing. Simple, huh?

Just fill the balloon, tie and rub on the garment for 1 minute or a little more.

Then bring the balloon closer to your child’s hair: the strands will get goosebumps and stick to the balloon! You can repeat the process and touch the balloon against the wall: in this case, it is the balloon that will stick.

Explanation: When rubbing the balloon on the woolen clothing, it is loaded with electrons (negative particles). From there it will attract what is positively charged, such as the hair strands. You can even test different objects, such as pieces of paper, to see which ones stick or not.#2 Lava Bottle – Density

Remember when the futuristic air of lava lamps was super trendy? Because this scientific experiment, besides being a success with the children, will still provide you with a certain nostalgia for that time, and it’s a great way to show the little ones what is density.

To make a lava bottle, you will need a clean plastic bottle (it can also be a transparent pot), water, vegetable oil, effervescent tablets (these of baking soda and citric acid that you find in pharmacies) and food coloring.

First, mix the dye and the water. Fill the bottle with colored water up to about 1/4 of the capacity. Pour the vegetable oil into the bottle until it is almost full – the tip here is to use a funnel to avoid spilling the oil.

If there are a few bubbles left, wait a while while the oil and water are apart. Then just throw the effervescent tablet into the bottle – the bubbles will start to form!

If you have a flashlight, leave the room dark and project the light through the bottle. The lava lantern is ready!

Explanation: Since oil and water do not mix, the oil floats on the water because it is less dense than it is. “Less dense” means that if you weigh the same volume of water and oil, the oil will be lighter. As the tablet dissolves in water, it forms carbon dioxide.

The gas is lighter than water and that oil, and so floats to the top, bringing some colored water along. When the air reaches the end of the bottle and is released, the water he has loaded becomes heavy again and sinks.#3 Pepper in water – Surface Tension

To do a scientific experiment that explains the surface tension, just a bowl, ground black pepper, detergent and some water. It is ideal to make children understand the concept in a visual way, bringing science closer to what they can see and touch.

The first step is to put some water on the bottom of the bowl – about 2 inches high is enough. Then sprinkle the ground pepper in the water so that it covers as much of the surface as possible.

It is now that your child will lick his finger with the detergent and try to touch the water: the pepper corns will immediately move away from the finger. It looks magical!

Explanation: The soap is breaking the surface tension of the water! Water has high surface tension, that is, the surface layer of the liquid behaves like an elastic membrane and the molecules (H2O) are very glued together.

But when soap is added, it breaks the surface tension. Thus, the molecules that were close to the finger are pulled by the molecules that are farther away, taking the pepper along with them.#4 Paper Tube – Capillarity

Has your child ever noticed how a piece of paper can function as a kind of “pipe” to pass water from one container to another? Because this scientific experiment will take care of it. And you can do it with two, three or as many glasses as you want.

Here, we recommend at least three, but it’s even more impressive if you do it with four or five glasses. To do the experiment, just have the glasses, water, paper towel and dye, plus books or other type of support that can be used to create a “ladder”.

Assemble stacks of books so that each step of the ladder is the same height as the cup. The first step will be the size of a cup, the second will be the size of two cups, and so on. Place one cup on each step and one at the base of the stack.

Then fill the first glass with water. Place a few drops of dye in the other cups, except for the one at the base of the ladder. Take the sheets of paper towels, twist them and place to connect the first glass to the second, the second to the third, and so on, until the last glass.

It is important that the paper touches the bottom of the glass above and does not touch the bottom of the glass below.

Now just wait: the water will start to come out of the glass that is at the top of the ladder and be transferred to the others, taking the dye along. After a while, only the glass that was on the floor will have water!

This is one of those experiences that you set up and the child is watching throughout the afternoon, for example. Oh, and it’s even cooler if you can use a camera or cell phone to make a time-lapse of the process. It’s great to watch later!

Explanation: Water rises through the paper towel through a process called capillary action. Capillary action is the ability of a liquid to flow upwards, against gravity, in narrow spaces. It’s the same thing that helps water rise from the roots of a plant to the leaves at the top of the trees. Because paper towels (and any paper) are made of cellulose, water is transported in the gaps between cellulose fibers, which act as tubes.#5 Erupting Volcano – Chemical science experiments Reactions
