Preschool Science Experiments Hands-On Learning

Hands-On Learning for Preschoolers: 10 Kid-Friendly Science Experiments

As parents or educators, we want to provide the best learning opportunities for our preschoolers. Hands-on learning is an excellent way to engage and stimulate young minds while also teaching them valuable scientific concepts. Science experiments are a great way to introduce preschoolers to basic scientific principles in a fun and engaging way. In this article, we’ll explore ten kid-friendly science experiments that are perfect for preschoolers.


Magic Milk Experiment

The magic milk experiment is an exciting way to teach preschoolers about chemical reactions. For this experiment, you’ll need whole milk, food colouring, and dish soap. Start by pouring the milk into a shallow dish, and then add a few drops of food colouring. Next, add a drop of dish soap to the mixture, and watch as the colours swirl and mix together.


Dancing Raisins Experiment

The dancing raisins experiment is a fun way to teach preschoolers about density and buoyancy. You’ll need a clear glass, raisins, and soda water for this experiment. Begin by filling the glass halfway with soda water and then dropping in a few raisins. Watch as the raisins dance and move up and down in the glass.


Rainbow Walking Water Experiment

The rainbow walking water experiment is a colourful way to teach preschoolers about capillary action. For this experiment, you’ll need three clear glasses, paper towels, and food colouring. Fill the two outer glasses with water and add a few drops of food colouring. Place a paper towel between the two glasses, making sure it touches both the water and the coloured water. Watch as the colours walk up the paper towel and mix in the middle glass.


Balloon Blow-Up Experiment

The balloon blow-up experiment is a fantastic way to teach preschoolers about air pressure. For this experiment, you’ll need a balloon, a bottle, and a straw. Begin by inflating the balloon and then placing the neck of the balloon over the top of the bottle. Next, insert the straw into the balloon, and blow air into the bottle. Watch as the balloon inflates on its own due to the change in air pressure.


Eggshell Geodes Experiment

The eggshell geodes experiment is a unique way to teach preschoolers about crystal formation. You’ll need eggshells, water, alum powder, and food colouring for this experiment. Begin by boiling the eggshells to sterilise them, and then let them dry. Next, mix alum powder, water, and food colouring, and pour the mixture into the eggshells. Let the mixture sit for several days and watch as crystals form inside the eggshells.


Baking Soda Volcano Experiment

The baking soda volcano experiment is a classic experiment that is always a hit with preschoolers. For this experiment, you’ll need baking soda, vinegar, and food colouring. Begin by creating a volcano shape with paper mache or playdough. Next, add baking soda to the crater of the volcano and then pour vinegar and food colouring over the top. Watch as the volcano erupts with fizzing and bubbling.


Lemon Battery Experiment

The lemon battery experiment is a fascinating way to teach preschoolers about electricity. You’ll need a lemon, copper wire, zinc nail, and a light bulb for this experiment. Begin by inserting the copper wire into one end of the lemon, and then insert the zinc nail into the other end. Next, touch the wire to the bottom of the light bulb and watch as the bulb lights up.


Invisible Ink Experiment

The invisible ink experiment is a fun way to teach preschoolers about chemical reactions. You’ll need lemon juice, water, white paper, and a cotton swab for this experiment. Begin by mixing equal parts lemon juice and water together. Dip the cotton swab into the mixture and use it to write a message on the white paper. Let the paper dry completely, and then hold it up to a heat source like a light bulb or a candle flame. Watch as the message appears as the heat reacts with the lemon juice.

Oobleck Experiment

The oobleck experiment is a messy, but fun way to teach preschoolers about non-Newtonian fluids. You’ll need cornstarch and water for this experiment. Begin by mixing equal parts cornstarch and water together. Watch as the mixture turns into a strange, goopy substance that behaves like both a solid and a liquid.


Crystal Snowflakes Experiment

The crystal snowflakes experiment is a beautiful way to teach preschoolers about crystal formation and patterns. You’ll need pipe cleaners, borax, hot water, and string for this experiment. Begin by bending the pipe cleaners into snowflake shapes and tying a piece of string to each one. Next, mix borax with hot water, and then submerge the snowflakes in the mixture. Let the snowflakes sit overnight, and watch as they become covered in beautiful crystal formations.

  • Why Hands-On Learning is Important for Preschoolers

    Hands-on learning is an approach to education that emphasizes active participation, exploration, and discovery. This approach is particularly important for preschoolers because it supports their natural curiosity and eagerness to learn. Preschoolers are at a critical stage of development where they are beginning to make sense of the world around them. They are full of questions and ideas and are eager to experiment and explore. Hands-on learning provides an opportunity for preschoolers to engage with the world in a meaningful way, to make connections between what they are learning and their own experiences, and to develop important skills like problem-solving, critical thinking, and communication.

    Research has shown that hands-on learning is particularly effective for young preschooler because it engages multiple senses and allows for the integration of new information with prior knowledge. This approach also supports the development of a growth mindset, which is the belief that intelligence and abilities can be developed through hard work, practice, and perseverance. By engaging in hands-on learning, preschoolers learn to embrace challenges, make mistakes, and persist in the face of difficulty, all of which are essential for success in school and in life.


    Safety Considerations for Hands-On Learning with Preschoolers

    When engaging in hands-on learning with preschoolers, safety is of the utmost importance. Here are some tips for ensuring that your science experiments are safe and enjoyable for everyone involved:

  • Always supervise preschoolers during science experiments. Even if an experiment seems simple or straightforward, accidents can still happen.
  • Wear safety goggles when necessary. If an experiment involves chemicals or other potentially hazardous materials, make sure that everyone involved is wearing appropriate eye protection.
  • Use caution with hot water and heat sources. If an experiment involves hot water or a heat source, make sure that preschoolers are aware of the potential danger and take necessary precautions.
  • Use caution with scissors and other sharp objects. If an experiment involves cutting materials, make sure that preschoolers are using safety scissors and are being supervised.
  • Follow all instructions and safety guidelines for each experiment. Before beginning an experiment, make sure that you have read and understand all instructions and safety guidelines.
  • By following these safety considerations, you can help ensure that your preschoolers have a safe and enjoyable hands-on learning experience.


    Ten Kid-Friendly Science Experiments for Hands-On Learning

  • Elephant Toothpaste Experiment: In this experiment, preschoolers mix hydrogen peroxide, dry yeast, and warm water to create a chemical reaction that produces a large amount of foam. This experiment is a great way to introduce preschoolers to the concept of chemical reactions and can be done with common household materials.
  • Walking Water Experiment: In this experiment, preschoolers use paper towels to create a “bridge” between cups of colored water. As the water travels up the paper towel, it creates a colorful display that demonstrates the process of capillary action.
  • Baking Soda and Vinegar Experiment: In this classic experiment, preschoolers mix baking soda and vinegar to create a chemical reaction that produces carbon dioxide gas. This experiment is a great way to introduce preschoolers to the concept of chemical reactions and can be done with common household materials.
  • Balloon Rocket Experiment: In this experiment, preschoolers create a simple rocket using a balloon, a straw, and string. By blowing up the balloon and releasing it, preschoolers can observe the rocket’s movement and learn about the principles of motion and force.
