Science Experiments for Kids can be a great way to get them excited about learning new things and to help them develop a deeper grasp of the world around them. We all know kids are always curious to learn and explore new things. In this blog, you’ll learn about 5 fascinating science experiments with step-by-step instructions and explanations :
5 Best Science Experiments for Kids To Learn
1. Volcano Eruption
- An empty water bottle
- Baking soda
- Red food colouring
- Dish soap
Step 1: Place the empty water bottle on a tray or a large container
Step 2: If desired, add a few drops of red food colouring to the water bottle to make it look like real lava.
Step 3: Fill the water bottle about 1/3 full with vinegar.
Step 4: Add a spoonful of baking soda to the vinegar in the water bottle.
Step 5: Now, watch the volcano erupt!
Baking soda contains sodium bicarbonate, when you mix it with vinegar (acetic acid), it produces carbon dioxide gas. When the pressure within the water bottle builds up until it eventually forces its way out in the form of bubbles, creating volcanic eruption.
2. Glowing Bouncy Egg:
- White vinegar
- Raw egg
- Clear jar or container with a lid
- Step 1: Put the raw egg in the jar or any container.
- Step 2: Fill the jar with enough white vinegar to thoroughly cover the egg.
- Step 3: Cover it and leave it for two to three days. Remove the egg from the vinegar after a few days and give it a gentle washing under running water.
Do you know the shell of the egg is made of calcium carbonate, which reacts with the acetic acid in vinegar to produce carbon dioxide gas. The gas bubbles off, leaving behind the egg’s membrane and yolk, creating a bouncy, translucent egg.
3. Dancing Raisins:
- Clear glass
- Carbonated beverage ( soda or sparkling water)
- Fresh raisins
Step 1: Fill the glass or jar about halfway with the carbonated beverage.
Step 2: Drop a few raisins into the glass and watch them dance up and down.
When you fill the glass with carbonated beverage and drop raisins on it then you’ll be able to see the rough surface of the raisins develops bubbles from the carbon dioxide gas in the carbonated beverage. The raisins are attracted to these bubbles and float to the top. The raisins drop back down once the bubbles at the top pop, giving the illusion that they are dancing.
4. Lava Lamp:
- Clear plastic bottle
- Food colouring
- Vegetable oil
- Alka-Seltzer tablets
- Step 1: Fill the bottle with vegetable oil until the container is roughly two-thirds full.
- Step 2: Add a few drops of food colouring to the oil.
- Step 3: Fill the remaining space with water but leave a little space at the top.
- Step 4: Break an Alka-Seltzer tablet and drop one piece into the jar.
- Step 5: Observe the bubbling and colour-mixing effect resembling a lava lamp.
When water and the Alka-Seltzer tablet interact, carbon dioxide gas bubbles are created. The colourful water is carried up by the bubbles as they rise through the oil, producing a captivating lava lamp effect.
5. Rainbow Milk Experiment
- A shallow dish or plate
- Cotton swabs
- Food colouring
- Dish soap
- Whole milk
- Step 1: Pour enough whole milk into the shallow dish until the bottom is completely covered.
- Step 2: Add a few drops of various food colouring in different spots on the milk’s surface.
- Step 3: Dish soap should be applied to the cotton swab’s tip.
- Step 4: Gently press the cotton swab with soap to the milk’s surface close to the coloured areas and observe
The food colouring floats on the milk’s surface because of its lower density. When you add dish soap, it reduces the surface tension of the milk, causing the colours to disperse and producing a beautiful swirling effect resembling a rainbow.
Science experiments for kids provide hours of excitement and also offer valuable learning experiences for kids. These Science Experiments for Kids help them gain a better understanding of their surrounding. Early exposure to the wonders of science can ignite a child’s love for learning and exploration of life.
