Introduce Exciting Stem Activities For Toddlers

STEM activities, STEM Preschool, and STEM toys for toddlers are the trendy topics of today. And for a good reason! Yes, STEM (science, technology, engineering, and math) subjects are the way of the future. When you hear the word STEM, you might be thinking about high-tech toys or STEM kits that are expensive. Today, we will look at STEM activities for toddlers that use simple items found around the house or at a local discount store.

No need to wait until grade school; you can introduce STEM activities for toddlers now. Keep in mind these easy STEM activities will not look like the complicated science experiments you remember from school. The principles will be the same, but we keep things easy, simple, and fun with readily available materials.

Before we get started, for clarification, when using the term “toddler,” we refer to children ages 2-3 years old.

STEM Play For Toddlers

At this stage, STEM activities for toddlers are all about curiosity and play. Giving your toddler the freedom to explore their surroundings, see how things work, and investigate cause and effect. You will see a lot of observation, questioning, experimenting, analyzing, concluding, and sharing. Remember, toddlers learn best through exploratory play and hands-on experiences!

Play is vital to your toddler’s learning and development. Fortunately, toddlers come by it naturally and are drawn to STEM activities because they are curious! You might not have thought of play as part of the STEM-based learning process, but it is crucial.

The best way to support STEM learning is through play and to make available materials, tools, and resources. For example:

  • Keep on hand open-ended supplies that may be used in multiple ways, like building sets and materials. Building teaches toddlers a variety of concepts and skills, all while they play and create.
  • Select resources and materials that encourage creativity and play while helping toddlers understand STEM ideas.
  • Encourage their play and curiosity through open-ended questions. Ask “Why?” and “What?” to start them thinking about building and playing in exciting new ways.

It is quite simple to incorporate quick STEM activities into your toddler’s routine. Let them be inquisitive, and most importantly,…Let Them Play!

What Are STEM Activities For Toddlers?

STEM projects for toddlers support the concept that science, technology, engineering, and math work together to help them become innovators, creative problem solvers, and critical thinkers!

In other words, a toddler STEM activity is a simple, structured but open-ended activity that allows your toddler to instinctively and curiously explore, which is essential to their growth and development. Furthermore, they learn to use their thinking skills to increase logic and creativity while boosting their fine and gross motor development.

The best part about STEM activities is the focus is on the process and NOT the results. STEM projects for toddlers work by incorporating STEM thinking into their daily activities.

For example, your toddler might:

  • Experiment with various materials.
  • Explore with their senses, such as taste, touch, and smell.
  • Investigate the basics of geometry and physics, including motion, gravity, and balance.
  • Measure, weigh, and count as part of their exploration.
  • Physically manipulate, connect, and shape objects to see how things go together and work.
  • Test cause and effect.
  • Utilize tools like a magnifying glass to investigate their surroundings.
  • Use STEM building materials to create something new.

The following STEM activities for 2-3 years olds are easily adapted to your toddler’s skill level. Use them to encourage STEM-thinking and inspire your own STEM ideas.

Since a toddler’s development is as individual as they are, your child may or may not be ready for the more challenging STEM activities. Start with the simplest STEM challenges, and slowly increase the difficulty when your toddler is prepared for more complicated STEM activities and projects.

Let the fun engineering activities begin. All building and engineering activities are fantastic for STEM projects and hands-on STEM activities. But what could be better than an edible structure? Your toddler can build towers, sculptures, and geometric shapes while designing, testing, and problem-solving. When they are finished, they can enjoy the “fruits” of their labor one piece at a time.

What a great way to start snack time?

STEM Food Activities

Who says we can’t play with our food? How exciting to gather up a few edible materials and enjoy some STEM activities with food. Using these hands-on STEM activities, your toddler can build structures, steeples, columns, and bridges. Due to the variety of building materials, your child can experiment with what shapes and pieces make the sturdiest base and design. Expand the STEM play by adding Popsicle sticks or paper. The possibilities are endless!

play icon symbol Toothpick Marshmallow Tower

For this toothpick and marshmallow tower, you will need a box of toothpicks, a bag of marshmallows (regular or mini), and a flat surface; trays work nicely. We recommend starting with a limited amount of toothpicks and marshmallows to not overwhelm your toddler. Then add more if you see they are really engaged.

Before you begin this marshmallow toothpick tower challenge, you might talk about building a tower. “How high should we make it?” “What does it need to help it stand tall?” Then let your toddler jump in and get hands-on experience, which is how they learn best.

Start the marshmallow STEM challenge with the base. Encourage your toddler to build simple shapes like triangles and squares. The act of picking up the marshmallows and sticking the toothpicks into them is also great for fine motor development.

Once they have a few shapes built, together, you can work on connecting them to create a more expansive, stable base. Now comes the fun part, up you go! Have your toddler work on building up as tall as they possibly can. Be prepared for some trial and error. They may have to design and redesign, all of which is why this a STEM activity. In the end, measure the height, maybe take a picture and enjoy a tasty marshmallow snack.

Try one or more of these quick engineering challenges depending on your toddler’s skill level.

  • Cup Stacking STEM Challenge 1: Who can stack the tallest cup tower?
  • Cup Stacking STEM Challenge 2: Can you build a tower as tall as (X)? Let your toddler decide what X equals, for example, as tall as the couch, door, or your toddler.
  • Cup Stacking STEM Challenge 3: Who can build the tallest (X) cup tower? You determine the number for X based on the number of cups you have.

Optional: Index Card STEM Challenge: Add playing cards, index cards, card-stock, cardboard pieces, or Popsicle sticks between stacking cups to make a stable base that disperses the weight of the cups. Can you build an even taller tower with this extra support?

play icon symbol Boat Float STEM Challenge

This simple boat-building activity is a blast.

You will need:

  • A container of water to act as a lake or sea.
  • Each boat will require a 6″ x 6″ square piece of foil.
  • Have a pile of pennies available for testing.

Ask your toddler to shape the foil into a boat. Now test to see if the boat floats on the water.

To add an additional dimension to the activity, you can add pennies to the boat one at a time.

  • “How many pennies will the boat hold before it sinks?”
  • “Does the shape of the boat’s bottom make a difference?” For example, if they made a wide bottom boat or a narrow bottom boat.

For even further STEM-based learning, try two water containers, one with tap water and one with salt water.

  • “Does the type of water matter with regards to floating and sinking?”
  • “Which container of water and boat holds the most pennies?”

Playdough STEM Activities

Building with playdough is loads of fun and offers so many benefits from fine motor development to encouraging easy STEM activities for toddlers. Playdough is simple to make and inspires exploration, building, creativity, discovery, and imaginative play.
