5 Cool Science Projects for School Kids

Did you know there is a wide range of science experiments that you can do to impress your kid? Kids do learn a few science experiments at school. But, many of them are explained through oral communication, which eventually leads to boredom among kids. You can make your kids’ day exciting by spending quality time doing some cool science projects.

5 Cool Science Projects for School Kids

If you intend to increase your kids’ knowledge about Science, you should consider conducting some science experiments at home. Kids tend to remain more alert when they witness experiments through their own eyes. There are many household objects, ingredients, and tools to perform standard science experiments, such as the honey analysis experiment, in just a few minutes.

Below are some science experiments that you can do to blow-up your kids’ minds.

1. Growing crystals

The ingredients needed to create growing crystals are:

  • Borax
  • Pipe Cleaners
  • Water
  • Heat
  • Dye

You can bend the pipe into different shapes such as a heart, star, rectangular or triangular. Once you have your desired shape, you need to boil some hot water and put it in a recipient. Afterward, you need to dispose of the pipe cleaner and add the preferred dye in the recipient containing hot water. Spread borax solution evenly on the recipient and wait overnight for the borax to turn into a growing crystal.

Besides, it is crucial to inform your kid that those growing crystals are not candies as it can easily deceive a child’s eye. You need to be alert with your kids while doing this experiment so that there is no risk for them to eat those crystals.

2. Putting pencils through a bag of water

Usually, kids think if you apply pressure on a bag full of water, the bag will explode. This is where you can change that concept by doing an experiment that will leave your kid amazed.

To do this experiment, you will need:

  • Water
  • 10 sharpened pencils
  • A plastic bag

First, you need to fill the plastic bag with water. Hold the bag from the top corner. Afterward, you can start inserting pencils one by one. The technique is simple; you need to quickly insert the pencil on the plastic bag’s first layer. Then, push the sharpened part of the pencil on the other side of the bag. The polymers of a plastic bag do not allow the bag to explode. But remember to be sturdy with this experiment.

3. Self-inflating balloons

Self-inflating balloons will, for sure, leave your kid quite thrilled. A balloon can self inflate by using and following the steps below .

Put baking soda inside an empty bottle and fill a balloon with a small amount of vinegar. Afterward, place the balloon on the mouth of the bottle and make sure there’s no place where air can escape. Vinegar and baking soda, when mixed, will turn into a chemical gas, hence allowing the balloon to inflate on its own.

4. Honey Analysis

You can demonstrate to your kid how to identify good honey and bad honey by using the honey analysis techniques. 

There are 2 very effective methods to test for pure honey:

  • Flame Test
    You need to dip a dry matchstick in the honey and try to light it. If the matchstick lights up instantly, then you know that the honey is pure. And if it takes time, it will be evident there is moisture or added substances in the honey.
  • Thumb Test
    Another method to perform the honey analysis process is by using your thumb. You need to apply a small amount of honey to your thumb and let it remain there for a while. If the honey remains intact, does not spill or spread out, it is a clear indication of pure honey.

5. Pepper powder and water experiment

It can be challenging to explain to your kids about the presence of harmful bacterias found on their outer layer of skin. Hence, you can experiment with your kids to demonstrate the importance of washing hands regularly with soap or taking a bath.

  • Dish soap
  • Pepper powder
  • Water

To begin, put water on a plate and spread the pepper powder evenly. Tell your kids that the pepper powder represents bacteria. Afterward, put a drop of dish soap in the middle of the plate. Let your kid witness how fast the pepper powder dispatches itself away from the dish soap. This is a perfect way to make your kid understand why they should always think about their body hygiene.
