Just before attempting our first science experiment for children, here are some educational facts that every little experimenter needs to know. So, like all living things, plants, too, are essentially composed of water. As a result, today water will play a crucial role in our small laboratory. As for the remaining part, we discover several constituent elements, such as phosphorus, sodium, potassium and nitrogen. But where does the green color come from?

Where does the green color of the leaves come from?

Have you ever heard of chlorophyll? The molecule that gives your plants their green color and promotes the process of photosynthesis. A little like human digestion, the latter allows the greenery to grow and develop. So, here is a little overview of everything you need to know in order to realize the small science experiment for children.

In general, fresh plants, not those that have been in your fridge for days, are one of the key points in achieving our first plant experience. So, start filling your glass jars with water. Then add the different food coloring and plunge celery stalks (the latter, you can replace them with a few leaves of romaine lettuce). Leave overnight and discover the spectacular results early in the morning.

In addition, for the most curious among you, we find the same phenomenon in the animal world. Did you know that flamingos have to color their feathers with the food they eat? Rich in pink pigments, shrimps are one of the favorite delicacies of these exotic birds and therefore one of the reasons for the spectacular coloring of their feathers.

Aside from food dyes, you can also play with different types of plants. For this purpose, please favor those containing more water so that they can absorb enough colored pigments. Moreover, you can give free rein to your imagination and combine several colors. To do this, simply separate the rod in half and plunge each half into a different shade. The key point is indeed not to completely separate the rod, but rather to preserve its upper part. Demonstration on one of our examples above. Besides herbs, some flowers, such as roses and chrysanthemums, can also take advantage of this DIY coloring mode.

Scientific experiment for children to try in class or at home

To recreate this experience, you and your little ones do not need specific materials, but rather a little patience. Composed of a few relatively simple steps to follow, this idea is perfectly adapted to young people. What do you need to run your DIY project?

  • glass jar filled with water
  • freshly picked leaf
  • small magnifying glass

Fill your pot with water, put the green leaf in it and place it in a bright place. Wait about 30 minutes and observe what will happen on the surface of your plant. You see the oxygen bubbles? These bubbles are indeed a proof of the photosynthesis mentioned above. In other words, they show that your plant is still alive although it has been cut.

How to grow a bean in a CD box?

As for our next DIY idea, we assure you that there is nothing easier to achieve. This is an easy and super fun gardening for kids and adults alike. Educational and fun at the same time, this next experience is also very gratifying to the extent that your seeds germinate and form roots and leaves for only a few days. So all you need is an empty CD case, a piece of cotton and some dry white beans. A good alternative to these will be wheat, barley or the lens. However, coral lenses are to be avoided because they are usually shelled and therefore will not germinate.

First, it is very important to soak your seeds overnight. Then take your CD box and lay a layer of cotton on it. Moisten it well, but be careful not to drown it. Finally, spread out the seeds and leave everything at room temperature. To speed up germination, you can cover your seeds with another layer of wet cotton. For the next few days, watch for the moisture of your cotton, and if necessary, adjust it with a spray bottle. Your beans should normally germinate in two to three days. If this does not happen, do not insist and renew your little science experiment for children!

Scientific experiment for children: create a mini garden from rubbish!

Grow a small indoor garden from rubbish? Yes, it is quite possible thanks to our next scientific experiment for children who will present you some plants to grow from leftover food. Believe it or not, some food debris can be very easily turned into a healthy and delicious product to eat every day. So instead of letting them end up in the trash, give them a second chance while helping to reduce food waste. Say “stop” to the latter and opt for our next science experiment for children. Small key point to remember: before starting to consolidate your food waste, it is important to ensure that your fruits and vegetables are organic. Why? Because foods sprayed with herbicides do not give a second generation.

Celery, lemongrass, romaine lettuce, shallot, pineapple, carrots, mushrooms, avocado or coriander … these are just some of the options you can try at home. So instead of throwing them out, soak their roots in a container filled with water, just as shown on our examples, and place them in the sun. During the growing season, make sure the water level stays the same. After a few weeks, you can plant your celery, shallot or pineapple in a pot or why not in your garden?

Scientific experiment for children – how to sprout a avocado pit?

The same experience you can achieve with avocado kernel. So, after tasting your delicious little avocado, take its kernel and clean it thoroughly. Then dip it in a little hot water and let it sit for about 30 minutes. At the end of this time, let it dry in the sun or in a well-ventilated area. Then plant four toothpicks and place on a small glass jar as shown above. Note that the pointed side of your core should be placed upward, as well as the water should be changed regularly. If all this has been done correctly, after two weeks, your nucleus must be ready to plant. Now, do not miss the rest of our scientific experiments on the theme of the plant world!
