Simple and Fun Science Activities for Preschoolers

activities for preschoolers

While preschoolers can’t comprehend advanced scientific concepts, you can still incorporate some basic experiments into their everyday life. These activities not only spark your kid’s curiosity but also provide easy entertainment. While some activities have the added bonus of sensory or motor skill development, others possess a basic knowledge about elements. Read on for instructions about our fun science activities for preschoolers.

Magic Milk 

You just need to fill a plate or bowl with milk (whole milk works best). Next, drop a few drops of food coloring into the milk. Dip a cotton swab in dish soap, then encourage your child to swirl it around the colorful milk. A small reaction happens when the soap touches the milk that is very intriguing to see. Also, it will create a marbled effect that’ll generate plenty of wow-moment from your kids.

In addition, you can also take this activity one step further by making a pretty painting from it. Simply grab a piece of paper, dip it in the surface of the milk, and hang it up to dry. Tada! You have some artworks to stick on your fridge.

Oil and Water

Teach your preschooler that oil and water don’t mix together with this at-home science experiment. To start, add a few drops of food coloring into  vegetable oil or olive oil. Next, pour the mixture into a glass of water. The oil, which has a lower density than water, will remain at the top of the glass while the denser  food coloring will fall down and create “fireworks” below. Your child will be amazed by the colorful rain shower, and they’ll visually see the effects of density.

Invisible Ink

Kids love mystery things. And, with this unique science experiment, your preschooler can also practice their writing skills. Squeeze a lemon into a bowl, along with a spoonful of water. Your child can grab their paintbrush or a cotton swab, dip it in the lemon juice and draw on a piece of paper. Once the paint is dry, they won’t be able to see it. But, it’ll miraculously appear when it’s close to a source of heat such as a light bulb. And then, slowly explain to them that lemon juice turns darker from oxidation when it heats up. Now, enjoy sending secret letters to each other and make everyone else curious.

Homemade Slime

activities for preschoolers

No kids can turn down the joys of slime. Although you can find many slime tutorials online, the basic recipe only needs a bottle of glue, ½ teaspoon of baking soda, and 1.5 tablespoons of contact solution. Mix everything together in a bowl, adding glitter or food coloring if desired. Also, you adjust by adding warm water for stretchier slime or cornstarch to make it drier.

Once it’s ready, encourage your child to test and explore their slimy creation. Playing with the slime offers a fun sensory and textural experience, which also helps develop your child’s motor skills.

Float and Sink

activities for preschoolers

Fill a large container with water; it can be a kiddie pool or a bathtub. Then layout a variety of objects with different densities. Encourage your kid to guess the outcome every time they put an object in the water. And then, let the experiment begin to see whether it sinks or floats. This activity introduces the concepts of buoyancy and density in the simplest way. The sensory and water play aspects will also keep your preschooler entertained for quite a while.

Shiny Pennies

activities for preschoolers

Although preschoolers don’t necessarily understand chemical reactions, they still find the visual evidence appealing. Also, your kid might want to have a coin collection. So, this activity will teach your child how to make things shinier. Scrounge up some pennies from your wallet or coin jar. The dirtier, the better! First, let your child pour vinegar into a glass. And then, mix in about a teaspoon of salt, stir to combine. Next, have your child drop their dirty pennies in and stir everything around for a few minutes. And, watch your kid admire their new shiny surface after washing them off.

Glass Harp

activities for preschoolers

Your child would be surprised when they see normal things like a glass of water can create beautiful sounds like a real instrument. Gather a handful of glasses and fill them with different amounts of water. Have your child gently tap on the glasses with an object, such as a spoon, to create some catchy tunes. They’ll quickly learn that each glass creates a different noise. While emptier glasses correlate to higher pitches, fuller glasses make deeper sounds. Also, if you can, try to play their favorite kids song with it or go pro with glass harp skills.

Yardstick Catapult

No one can say no to this interesting weapon. A DIY catapult launcher will provide hours of scientific fun with your kid! To make this, glue plastic cups to the end of a yardstick. After it’s dry, position a metal can (like a coffee can) halfway down the yardstick, and attach it with rubber bands. Load small, soft items like lightweight balls into the cups. And, have your child step down or jump on the opposite end of the yardstick to fire. Have your preschooler try with different objects and varying amounts of effort. Or, make a cardboard castle and let the fun begin!

Build a Lego Volcano

There’s nothing better than baking soda and vinegar experiments to discover the fun of chemical reactions! Your child will probably have a lot of extra Lego pieces and this time they can use it with their imagination to make a volcano. Put a bottle or jar in the middle of the Lego volcano to contain the reaction. Remember, the smaller the mouth of your volcano, the stronger the explosion will look like. With 2 main ingredients, which are baking soda and vinegar. Mix in equal amounts and you will have something resembling a volcanic eruption!

It’s never too young to learn about science. And, with a kid’s curiosity, your kid will not only learn some knowledge but also have a lot of fun while doing it. Moreover, some of the experiments can benefit your child’s future life or their first science project. Have fun with your kid and let’s do some science now!
