The Top 3 Colourful Science Experiments that Your Child Will Love!
We all love a life that is colourful and vibrant! While Phase 1 continues in Singapore, here are some cool and colourful science experiments that you can try at home as educational activities for your child’s learning!
1.Fluffy Slime Experiment
Fluffy Slime has been a sensation on the Internet, particularly among children and youths! It is relatively simple to make, however, a word of caution: adults should carefully supervise! If you or your child have sensitive skin, remember to wear some gloves! You will need:
- Elmer’s White Glue (2/3 Cup)
- Baking Soda (1/2 teaspoon)
- Water (1/4 Cup)
- Shaving Cream (2-3 Cups)
- Contact Lens Solution (1.5 Tablespoons) Do take note that the contact lens solution MUST have boric acid and sodium borate in its ingredients list for the experiment to work (this is what causes the glue to turn into slime)
- Food Colouring of choice (you can use as many colours as you’d like!)
- A large bowl
Add the white glue into the bowl, followed by the water and baking soda. Mix well. Next, mix in the shaving cream. Once complete, add in the food colouring of choice. If you are using multiple colours, mix each colour in separate batches first! Add in one tablespoon of contact lens solution after that. Begin to knead the mixture. It will be sticky in texture, and it is completely normal that the mixture sticks to your hands. Once kneaded, add in the final half tablespoon of contact lens solution. At this point, the mixture will be less sticky. Do note: If you add in too much contact lens solution, the slime mixture may harden.
Make a batch of different coloured slime and mix them together! They behave in the same manner as play dough and will eventually mix into one colour. The slime can be kept for a week in an airtight container!
2. Rainbow Bubble Experiment
This experiment is just as colourful as the previous! And a great way to introduce chemistry to your little one. All you will need are:
- Baking Soda
- A bowl
- A large tray
- Syringes or droppers
- Food coloring (in every colour of the rainbow)
The first step of the experiment is to ‘dye’ the baking soda. Pour in four tablespoons of baking soda into a bowl. Next, add in 2-3 drops of food colouring, followed by one or two teaspoons of water. Mix well. The mixture should be clumpy, but now water. Repeat for the rest of the colours. Place the different coloured baking soda mixtures into the large tray, according to the colours of the rainbow. Then, fill up the droppers or syringes with vinegar, and let your child drop them into the baking soda. Enjoy what happens next and encourage them to describe what happens!
Want to introduce density and polarity to your child? Check out this cool experiment. All you will need are:
- Vegetable Oil
- A Flask or Bottle
- Food Colouring
- Baking Soda
Fill the flask with vegetable oil, followed by water. The water should sink to the bottom of the flask due to it having a higher a higher density than oil. Next, add in a few drops of food colouring of your choice. The colouring will mix with the water and sink as well, since it also has a higher density than oil! Next comes the fun part – add in a little baking soda into the mixture and observe what happens! Due to the baking soda coming into contact with the water, carbon dioxide forms as a chemical reaction takes place. This carbon dioxide that forms helps to ‘power’ the lava lamp as they stick to the water and colouring, cause the mixture to move upwards within the flask since the gas and liquid combination has a lower density than the oil! Repeat as much as you’d like!
We hope you and your child enjoy these educational activities! Should you and your child be interested in science and scientific endeavors, check our our YMCA Learning Centre STEM programme! This programme aims to spark an interest in students in learning how the world around us works, through experiential learning. Do contact us to find out more!
