5 Popular Sciences That Your Children Will Love


The best way of teaching a science minded child is through experiments. This is because a child can’t forget a process that happens right before his eyes. Experimenting helps a child understand basic science concepts much better than when he just reads his text books. The good thing about these experiments is that they can be done either in school or at home. Besides that, the materials that are used are easily available. However, you should be ready to clean up because some can be quite messy. Below is a list of popular science experiments that you can teach your child.

1. Night and Day

This experiment is intended to help your school going child understand how the days and nights are formed. The experiment is very simple because you only need an orange and a flashlight. In fact, you can do this experiment indoors. To get started, simply turn on the flashlight and hold the orange fruit with the other hand. The light of the torch should be directed towards the orange from one direction. You will realize that light will only shine on the side that is directly facing the flashlight. The other side of the orange will remain dark due to lack of light. When the orange is rotated slowly, the light shifts from the part that was shining to the other that was dark. You should explain that days and nights happen because the world rotates around the sun slowly. To make the experiment more interesting, you can have the child hold the flashlight.

2. Evaporation of Water and other Liquids

The aim of this experiment is to teach children how various substances including water change from one state to the other namely: solid, liquid and gaseous. For this experiment, you don’t have to buy anything because you will only need to use a cooking pot and a source of heat. Get an ice cube from the freezer of your fridge and put it in a cooking pot. Since the ice cube is now in solid state, you should place the pot on top of a cooker that is already turned on. The heat of the cooker will make the frozen ice to melt into liquid. When temperature in the port builds up, the water will start boiling and eventually evaporate into the air.

3. Filtration of Water

In this simple experiment, the focus is purify water naturally. You actually need a plastic bottle, sand, gravel and charcoal. The bottle should be cut at the middle to make two halves. The part with the bottle top should be used for holding sand, gravel and charcoal. The sand should make the first layer inside the bottle followed by the charcoal and the gravel. You should make a small hole on the bottle to so that the water can drip down. You should then put water in a different container, mix it with soil. The mixture should then be poured into the filtering bottle. The gravel, sand and charcoal will help in removing the soil from water and other impurities.

4. Heating Properties of Colors

Different colors attract temperature differently. Black naturally absorbs more heat than other colors. That’s why the sun feels hotter when you are in dark clothes. You can demonstrate this fact using ice cubes and several pieces of clothes that are not of the same color. You should get different pieces of cloth that come in various colors including blue, white, black, red, and green. The experiment should be done on a sunny day. The pieces of clothes should be spread outside on the glass. You should then put a piece of ice on each piece of cloth. After about an hour or so, you will realize the ice on the black piece of cloth melts faster than the rest.

5. Process of Osmosis

Osmosis is a process through which substances move from high concentration to low concentration. All you need for this experiment is a tea bag and a cup of hot water. During osmosis, substances move through a semipermeable membrane. As a matter of fact, the membrane serves as a filter that only allows small particles to move into the side with the lowest concentration. When you dip a tea bag into a cup of hot water and allow it to rest for about 10 minutes, you will realize that the teabag will still be intact, but the water will have changed in color.
