As parents, we all want to give our little ones the best start in life, especially when it comes to learning and curiosity. STEM education (science, technology, engineering, and math) is becoming a cornerstone of early childhood development, sparking creativity, problem-solving skills, and a lifelong love of learning. But how can you bring STEM learning into your home in a way that’s simple, engaging, and fun for your preschooler?
At Discovery Time Learning Center in Alexandria, VA, we believe that learning through play is the best kind of learning. That’s why we’re sharing some easy and exciting STEM activities you can try with your preschoolers right at home. Plus, if you’re looking for a daycare that supports early STEM education, we’re here to help with full-time, part-time, and drop-in options.
Why STEM for Preschoolers?
Before we dive into activities, it’s worth understanding why STEM matters for young children. At the preschool age, kids are naturally curious about the world around them. Introducing STEM concepts early helps nurture this curiosity and builds foundational skills like observation, inquiry, and basic reasoning. These early experiences can boost confidence and set the stage for more advanced learning later on.

5 Fun STEM Activities to Try at Home
Here are some simple STEM activities perfect for preschoolers, using materials you likely already have at home:
1. Sink or Float Experiment
What You Need:
- A large bowl or tub filled with water
- Various small household objects (e.g., a spoon, a leaf, a cork, a coin)
What to Do:
Have your child predict whether each object will sink or float, then test their predictions. Talk about why some objects float and others sink—introduce simple terms like “density” and “buoyancy” in a playful way.
Why It’s Great:
This activity sparks scientific observation and hypothesis skills while being super tactile and fun.
2. Build a Paper Tower
What You Need:
- Paper or lightweight cardstock
- Tape or glue
What to Do:
Challenge your preschooler to build the tallest tower they can with just paper and tape. Encourage them to think about how to make it stable and tall.
Why It’s Great:
This introduces engineering basics and encourages problem-solving and creativity.
3. Color Mixing with Water
What You Need:
- Clear cups or jars
- Water
- Food coloring (red, blue, yellow)
What to Do:
Fill cups with water and add drops of different food coloring. Let your child mix colors in empty cups to discover new colors.
Why It’s Great:
This activity teaches about color theory, experimentation, and cause and effect.
4. Nature Scavenger Hunt
What You Need:
- A list of natural items (leaf, rock, flower, stick)
- A basket or bag
What to Do:
Take a walk outside and have your child find items from the list. Once home, sort the items by size, color, or texture.
Why It’s Great:
This encourages exploration, classification skills, and appreciation of the natural world.
5. Simple Shape Sorting
What You Need:
- Cut-out shapes from paper or foam
- Containers or boxes labeled by shape
What to Do:
Have your preschooler sort shapes into the right containers, or match shapes to objects around the house.
Why It’s Great:
This builds early math and geometry skills through hands-on sorting and matching.
