  2. 3 science experiments for kids that help the environment 


Science is undoubtedly one of the most exciting and fun fields of study that exists, but many times in school it is not taught as it should be. The result is that students loathe it and decide not to be interested in it. This is why solutions must be sought to try to teach science in a more entertaining way, and this is where science experiments come into play. ๐Ÿ”ฌ In this article weโ€™ll show you some science experiments for kids that are, for sure, very interesting for children of all ages. science-experiments-for-kids

Why are experiments so useful while teaching science


As mentioned above, science can be somewhat tedious in school and that is why teachers, tutors and parents must try to capture the attention of children so that they show interest in it. Science experiments for kids are a very good solution to this, as there is no better way to teach science, than by showing it. ๐Ÿงช


3 science experiments for kids that help the environment


As you already know, science covers a lot of different fields of study: physics, mathematics, biology, chemistry... and it is very difficult to address all of these in only one article. That's why we are going to focus only on science experiments for kids that help the environment. That is, eco-friendly experiments that use mostly natural materials, ๐ŸŒฑ as they are a very interesting, simple option, and that can teach a lot of concepts to your child. ๐Ÿค”

It is very important to emphasize the scientific method in these experiments for kids. The scientific method is based on proposing hypotheses about what will happen when an experiment is performed. So your child should ask himself what he thinks will happen when these experiments are performed, in order to also enhance his capacity for deduction. ๐Ÿง 

Homemade water purifier

This is a very interesting and simple experiment to perform. For this one we only need: 

  • Plastic bottles ๐Ÿงด
  • Cotton
  • Small stones 
  • Large stones
  • Sand 

We will cut 2 bottles in half, and place some cotton in the hole of one of them. Inside this we place sand and small stones, while in the second bottle we will place the big stones. Now the first bottle is introduced inside the second one, so that both are connected to each other, forming a conduit. Finally, a container or bottle is placed at the end of the conduit, where the filtered water will fall. 

If we throw dirty water through the beginning of the conduit, as it passes through the different filters formed by cotton, sand, small stones and large stones, the water will be purified. ๐Ÿ’ง The more times you pass the water through the purifier, the cleaner it will be. 

Making homemade compost

Compost is a natural fertilizer obtained from the degradation of organic matter. It is widely used in gardening and agriculture, as it is a perfect fertilizer. To make it, it is necessary: 

  • A very large container 
  • Soil 
  • Organic matter that you have generated at home
  • Leaves, branches and wood of trees ๐Ÿƒ

The process is very simple, as you only need to mix everything inside the container, cover it tightly, stir and wait. The decomposition process is carried out by microorganisms and can generate bad odor, ๐Ÿคข that is why we recommended that you do this at outside and not indoors.  

Can you put an egg in a bottle? 

This is a clear example of a science experiment for kids who love science, because it explains concepts that are somewhat more complex than in the previous experiments. The materials needed are: 

  • Vinegar 
  • Egg ๐Ÿฅš
  • Bottle ๐Ÿงด
  • Matches 
  • One candle ๐Ÿ•ฏ๏ธ

The first step is to place the egg in a container with vinegar for at least 24 hours (if you leave it 48 hours better). This is necessary because under normal conditions the egg shell is hard and under no circumstances would it enter the bottle. What the vinegar does is to react with the calcium carbonate in the egg shell, making the egg look like rubber. 

The next step is to put a lit candle into the bottle (this is a step that you as a parent should perform, to avoid unnecessary risks). Now what you have to do is to place the egg over the mouth of the bottle and wait for the experiment to take effect. โฒ๏ธ 

If you have done everything right you should be surprised to see how the egg has entered the bottle by itself and you will wonder how it happened. Well, the egg has acted as a stopper for the bottle, which has caused the flame to consume all the air that was inside the bottle. When this happened, a vacuum was generated, which caused a negative pressure to be exerted on the egg, which, thanks to being rubbery, allowed it to be sucked into the bottle. If you were to do this same thing with a hard-boiled egg, it would crack. ๐Ÿ˜…

See? There are many cool experiments for kids that, while teaching science in a fun way, can also help the environment, as they are using recycled materials or natural resources. Let us know if you do one of these at home! We are looking forward to seeing the results!
