Did you know science experiments that our children are scientists eager for nature? Since babies, they want to experience everything the world has to offer and test their possibilities in practice, and that’s where scientific experiments come in.
There are some activities related to concepts of science that amuse and arouse curiosity while teaching theory to little ones, do you believe? In this post, Brandili’s Blog has prepared the best ones for you!
To flourish the mini scientists that exist in children and eliminate the possibility of child stress on vacation, continue reading and see 5 fun and simple experiences to do at home:1. What dissolves in water?
For starters, let’s look at an idea of a scientific experiment for younger children who, as we know, are as curious and aweable to see new things as their older siblings. To do this experiment, it takes two glasses with water, spoons, some sugar and some sand.
The first step is to ask the child to analyze the last two materials in separate cups, asking questions such as “Do you think they look alike?” and “What makes them look alike?”. The little ones always deduce that they are similar, because they are made of loose and small grains.
The next step is to put some water in the sugar cup, surprising the children because the material apparently disappears as a magic trick.
Then repeat the process in the sand cup and you will have a very confused son as to why the two, who believe they are similar, reacted in different ways in the liquid.
This is the time to explain the science behind: what happened to sugar was dissolution, a process that involves a solvent (water) and a soluble (sugar grains). With the sand, the process is called suspension – as their particles cannot be dissolved like this, they end up only spreading through the water.
While you’re explaining this, the sand will sit at the bottom of the glass and you can take advantage of the cue to formulate new hypotheses with the little one, such as “Why does it always stop at the bottom?” and “What happens if we put too much sugar in the glass?”.

2. Filling bladders in a fun way
First of all, as this experience can end in a mess, we recommend doing it in the garage or in the garden – always taking precautions regarding possible childhood insolation. Vinegar, baking soda, funnel, bladders and a plastic bottle (can be varied sizes) is all you need.
To begin with, fill or ask the children to fill the bladders, as they need to be elastic to avoid the risk of bursting. Then use the funnel to place the bicarbonate in the bladder and vinegar in the bottle (in a ratio of 1 spoonful of bicarbonate for every 100ml of vinegar) and place the bladder carefully in the mouth of the bottle.
The baking powder will fall into the vinegar and foam a lot, filling the bladder instantly. Pretty cool, huh? The explanation behind is that the chemical reaction between the two components produces the carbon dioxide that generates the bubbles.
3. Are we going to learn about density?
Honey, water, oil, food coloring and a pot is all you need to teach children density with this experience. Some extra objects of different densities (such as noodles, rubber, wrench, etc.) can also be used. The premise of the experiment is that by mixing these liquids and items in the pot, children will be able to see how different their weight/density is.
Only the dye is optional, but we recommend using because there are colors that stimulate children’s learning. To begin, put honey and ask the children if it looks heavy or light. When putting water, those who answered that honey is heavy can prove that they got it right, because the substance is under water.
Repeat the same with the oil and they will notice that it is the lightest, as it is right at the top of the pot. In addition to explaining the weight of materials, it is important to teach children that substances of very different densities do not mix.
The experience continues with the objects: ask which ones they think will sink and test by placing them in the pot mixture.
4. Invisible ink for secret messages
Yes, it’s true: you can make a fascinating invisible paint at home in a super easy and fast way! For this, prepare the materials, which are lemon juice (Sicilian, Orange or any other), brushes, sulfite paper and hair dryer. Children should use the juice to draw or write with the brush on the paper, only taking care not to soak and tear.
Saw? It’s so easy that you can be inserted into the children’s routine spreadsheet at the time mom has to cook and there’s no way to keep the little ones entertained. Look at that cool: Mom prepares the lemonade from lunch while the children pick up the rest of the fruit to write the secret message of the day!
The revelation of the invisible message comes with the help of the hair dryer: with the heat and air, the citric acid of the lemon changes color and gets darker, which is the same reason why we should avoid going to the sun with remnants of the fruit on the skin to avoid the appearance of stains. Soon, do this experience indoors and have fun with the kids.
Oh, and another incredible benefit of this experience is that by putting children to write, it stimulates the evolution of their motor coordination!
5. Soap bubble that does not burst
To finish the post with a golden key, we have apart an excellent idea to encourage friendship between children. For this experience, you only need the ordinary soap bubble liquid and a synthetic wool glove. Ask the children to make the bubbles normally and try to catch them with the glove: the bubbles will be cushioned and will not burst!
This is because of the hydrophobic property of the synthetic glove: its polyester molecules/fibers have low polarity chains that do not form interactions with the bubble, which allows it to only “land” on the hand. In other words, the soap bubble does not wet the glove and loses its water, so it remains intact.
If you have more than one child at home, we suggest having enough wool gloves available for everyone – parents know that they are not always willing to wait patiently for their turn to play, right? To avoid children fighting at the time of the experience, it is good that each has its own glove to have fun at will.
After so many experiences, children deserve a nice rest. To recharge the mini scientists’ batteries, gather them on the couch, prepare a healthy snack, and play in an educational and fun movie on Netflix!
