1. Creating a Rainbow

This fun science experiment will reveal that the sunlight has seven colors that we cannot easily see. Prepare to split the light of the sun into red, orange, yellow, green, blue, and indigo as you discover the creation of a rainbow.

2. Music from Glasses of Water

You can make cool sounds and soft melody with this unique musical instrument: drinking glasses or jars filled with water. The vibrations you make as you hit the glasses turn into sound waves that travel through the water. If you listen carefully and use notes that complement, you can produce heartwarming music.

3. Making Secondary Colors

When you only have primary colors to use, can you still end up with a colorful artwork? But of course! With this fun activity, kids will learn to mix colors to form new ones. It is going to be a fun and exciting mixing experience with your magical paintbrushes.

4. Sinking or Floating?

Did you know that you can do scientific experiments without hurting your purse? Water and the gift of physics can save you in this activity. Find some toys, utensils, or other small objects at home that can fit in your container of water. You will be surprised to see that not everything will sink in the water. The heavier object will sink while lighter ones will float.

5. DIY Hanging Balance Scale

An activity that your little ones can do by themselves. From tying strings to weighing things. Since the Earth has gravity, it can pull down objects to the ground. Between two things you have to measure, the heavier ones will be closer to the surface of the Earth. In this science experiment, you will only need four things, a hanger, strings, and at least two small objects to compare.

6. String Telephone

Can our voice travel without a telephone? If you are about five (5) feet away from your friend, will you be able to hear his/her voice without shouting? In this learning activity, you will understand how our landline phones work. Delight as you are about to experience your voice travel through a string.

This string telephone allows you to hear voices from the other end as the vibrations travel through the tight string while you speak. The sound vibration travels from one end like a wave and turns back into sound again upon reaching the other end.

7. Colorful Water Crawl

A super easy and simple science activity that is fun to look at and exciting for a Pre-K to witness. In this hands-on project, adult supervision is a must. You may use different colors for each cup or just one for all. Either way, it will produce the same effect.

Walking Water Science Experiment 8

The movement of the water in a crawling or walking direction is what we call capillary action. 

It is an inherent ability of the molecules of water to rise and travel. This scenario is akin to what happens to water when it enters the roots of plants. The water goes up through the stem to reach the leaves.

8. Balloon Rocket Ship

Kids can explore science in just about anything, solid, liquid, and even gas. In this activity, you can show your kids the existence of gases that take the shape of their container. A balloon can become oval, round, or heart-shaped once inflated. Once the trapped air is released, you will see that your balloon will boost like a rocket launching as the air rushes out with great energy.

9. Lava Lamp

There are a lot of interesting facts that surround a volcano. These include the formation of diamonds, hot springs, and blistering lava. Most kids will be curious about these phenomena. To impress them and show how lava looks up-close, do this activity at home. Put some vegetable oil and water together in a glass container and drop a pinch of sea salt. Your oil blob will move like lava in the glass.

Adult supervision is necessary since this activity requires a particular vantage point. You can do this using a zip lock bag, a marker, and a glass of water. Light refraction, when total, can make things disappear before your eyes, but the image not totally refracted like the one on the zip lock bag will remain visible.

11. The Mentos Mint Volcano

Dissolving a candy using soda is something you would not want to try inside your tummy. Yes! It is something you have to explain to the younger ones. This activity can be messy. So, instead of staying inside the house, you must go to the porch or a garden area at home. 

It is an experiment that will show you how minty mentos can trigger an eruption of gasses from a bottle of soda drink. You’ll have a bubbly day ahead!

12. The Candle Inside a Glass

Playing with a candle is a definite no-no for kids. But in this activity, parents are encouraged to engage their children in the glass experiment with parental supervision, utmost diligence, and care.

This experiment shows that the pressure from the hotter air inside the glass is higher while the candle is burning. It pushes the water out. However, when the wick goes out, the air cools down. It results in the release of pressure inside the glass, causing the water to get sucked up.

13. Invisible Ink from the Sour Lemon Juice

The next activity is suitable for kids who love to send secret codes or messages and maps for hidden treasures. You’ll find out that when you dilute lemon juice in water, it becomes invisible. However, it oxidizes and turns brown when heated, making it a perfect medium to facilitate secret communication or hide confidential matters.

14. Instant Cloud in a Jar

The study of our water cycle is a bit easy nowadays. You can browse through the pages of your book, ask your parents, or even watch it on Youtube. However, seeing the formation of water vapor into clouds this close is something unique and quite exciting. 

In this experiment, you will be making your clouds inside a jar. You may add some food coloring to make the cloud extra fun to watch and more visible to your eyes.

15. Mini-Tornado

It is not only clouds that you can make inside a bottle. A tornado-making activity can be fun too. With a few drops of dishwashing liquid, glitter, water, and a bottle, you can make a mini-tornado inside your clear bottle. 

In this science experiment, you will learn about the centripetal force that directs the water to the center in a circular motion. It happens when you spin the bottle fast and in a circular path. The vortex you created inside the bottle will look similar to the vortex we can naturally find in hurricanes and tornadoes.
