How to do science experiments for kids isn't as complicated as parents think. Do you want to explore the magical world right at home with your child? Let Mykingdom suggest simple yet inspiring activities that help your little one develop thinking skills and a love of learning.

What to prepare for science experiments with your child?

Don't worry that you need professional tools or deep expertise. Doing science experiments with your child is actually very simple, starting from everyday items in the kitchen or your child's toys.

  • Common materials: Water, vinegar, baking soda, food coloring, empty bottles, bowls, candy, fruits and vegetables... Mykingdom believes you'll be surprised to see how these simple items can create something magical.

  • Safe space: Choose a spacious, easy-to-clean area with plenty of light. You can lay down a tarp or old newspaper to protect the floor.

  • Mental preparation: Most importantly is patience, a joyful spirit, and willingness to explore with your child—and to accept even small "failures"!

  • Science experiment kits: If you want your child to have more professional experiences, Mykingdom has many interesting science toy sets ready. For example, the 26 Magical Chemistry Experiments kit, the Snow-making experiments kit, the Crystal-growing science kit… which will help your child explore the world of liquids safely and colorfully.

5 fun science experiments for kids

Magic Milk

  • Preparation: milk, food coloring, dish soap, cotton swabs.

  • Method: Pour milk into a plate, add a few drops of food coloring, then dab a soap-dipped cotton swab into the center of the plate.

  • Phenomenon: The colors will spread and swirl to create a beautiful effect.

  • Explanation: The soap reduces the surface tension of the milk, causing the molecules to move and produce color effects.

<h3 dir=Water and Oil

  • Preparation: water, cooking oil, food coloring, a glass.

  • Method: Pour water into the glass, add food coloring, then pour the cooking oil on top.

  • Phenomenon: Water and oil do not mix, forming two separate layers.

  • Explanation: Oil is lighter than water and does not dissolve in it, so it rises to the top.

<h3 dir=Eggs float and sink

  • Preparation: two glasses of water, one egg, salt.

  • Method: A glass of plain water, a glass of salted water. Drop the egg into each glass.

  • Phenomenon: The egg sinks in plain water, floats in salted water.

  • Explanation: Salt water has higher density, helping the egg float.

<h3 dir=Rice grains dance

  • Preparation: water, vinegar, baking soda, rice grains.

  • Method: Pour water into the glass, add vinegar and baking soda, then drop in the rice grains.

  • Phenomenon: The grains will jump up and down in the glass.

  • Explanation: The reaction produces CO2 gas, which clings to the grains, making them rise and fall as the gas escapes.

<h3 dir=Invisible Ink

  • Materials: Lemon, water, cotton swabs, white paper, a candle or an iron.

  • Method: Squeeze the lemon to extract juice and mix with a little water. Use a cotton swab dipped in the lemon solution to write/draw on the white paper. Let the paper dry completely. At this point, the writing will disappear. To reveal the writing, lightly heat the paper with a candle or iron (make sure an adult supervises).

  • Explanation: Citric acid in lemon will be oxidized when exposed to heat, causing the writing to appear in a light brown color.

<h2 dir=Notes when performing experiments with your child

  • Safety first: Always supervise your child during the experiments. Ensure safe materials appropriate for your child's age are used.

  • Encourage questions: Let them freely explore and ask questions about what is happening. This helps develop critical thinking and problem-solving abilities.

  • Record results: Encourage your child to write down what they observed, thereby developing noting and analytical skills.
