Montessori science classroom for toddlers

In Montessori education, science is fundamental in fostering curiosity, critical thinking, problem-solving skills, and a love for learning in children. Montessori science curriculum covers a wide range of scientific topics, including biology, chemistry, physics, and earth science. Children are encouraged to conduct experiments, observe and record their findings, and develop critical thinking skills. The Montessori science curriculum also emphasizes the interconnectedness of all living things and the importance of caring for the environment. Children learn about sustainability, conservation, and the impact of human activities on the planet.

Montessori science activities for toddlers focus on hands-on, sensory-based experiences that encourage curiosity and exploration. Here are some simple and engaging Montessori principle-inspired science activities for toddlers, complete with steps to follow.

1
Sink or float experiment with water, leaf, cork and stone

Sink or Float Experiment

This classic activity teaches basic physics concepts by letting children explore density and buoyancy.

Materials

  • A small tub of water
  • Various objects (e.g., a plastic spoon, cork, stone, leaf, small toy, etc.)

Steps:

  1. Set up: Fill a tub with water and place the objects in a tray next to it.
  2. Introduce the concept: Explain to the child that some things sink, and some things float. Show an example, like a stone sinking and a leaf floating.
  3. Explore: Encourage your toddler to choose an object, make a guess (“Do you think it will sink or float?”), then place it in the water to see what happens.
  4. Observe: After each object, ask, “Did it sink or float?” Let them watch how the different materials react with water.
  5. Expand: You can add more objects over time, ask them to organize objects into “sinking” and “floating” piles, or have them test their toys.

Toddler planting seeds in a Montessori activity

Planting Seeds

This activity introduces toddlers to botany and the life cycle of plants. It’s hands-on, fun, and lets them see the growth process.

Materials

  • Small pots or cups
  • Soil
  • Seeds (e.g., beans, sunflower seeds)
  • Small watering can or dropper

Steps:

  1. Prepare: Fill a small pot or cup halfway with soil. Place everything on a table or tray.
  2. Introduce: Show the child a seed and explain that it will grow into a plant with sunlight, water, and care.
  3. Plant: Let the child put a few seeds into the soil and then cover them lightly with more soil.
  4. Water: Using a small watering can or dropper, let the child add a little water. Explain that plants need water to grow.
  5. Observe: Place the pots on a sunny windowsill and encourage the child to observe the plants daily. Talk about how they’re growing roots, stems, and leaves over time.
3
Toddler exploring magnetic and non-magnetic objects

Magnet Exploration

Magnets are a wonderful way to introduce the concept of attraction and magnetism.

Materials

  • A child-safe magnet
  • Assorted items, some magnetic and some non-magnetic (e.g., paper clips, spoon, plastic toys, coins, clothespins)

Steps:

  1. Set up: Arrange the items in a tray, with the magnet next to them.
  2. Introduce: Show the child how the magnet attracts certain objects.
  3. Explore: Let the child try picking up different objects to see which ones stick to the magnet. You can ask, “What do you think will happen with this one?”
  4. Sort: After they’ve tested each object, have them separate the magnetic and non-magnetic items into different piles.
  5. Expand: Explain that some materials are magnetic and others aren’t, and talk about examples they might find in their everyday environment.
4
Montessori color mixing with water experiment

Color Mixing with Water

This activity introduces the concept of primary and secondary colors in a visual, interactive way.

Materials

  • Clear cups of water
  • Food coloring in primary colors (red, blue, yellow)
  • Small spoons or droppers

Steps:

  1. Set up: Place the cups of water and food coloring on a tray.
  2. Introduce: Explain that they can combine two colors to make a new one. For example, blue and yellow make green.
  3. Mix: Let them add a drop of one color into the water, then add a drop of another color, and watch how the colors change.
  4. Observe: Encourage the child to predict the result before mixing each combination.
  5. Experiment: Let them create different color mixtures and explore how varying amounts of color affect the results.
5
Nature walk and sorting activity with leaves, rocks and sticks

Nature Walk and Sorting

A nature walk is an excellent way to explore the natural world and practice sorting and observation.

Materials

  • A small basket or bag
  • Tray with sections (optional)
  • Outdoor space (e.g., backyard, park)

Steps:

  1. Go on a Walk: Take a short walk outdoors and encourage your toddler to collect interesting things they find, such as leaves, sticks, small stones, and acorns.
  2. Observe: Once back inside, empty the collection onto a tray. Let them examine each item.
  3. Sort: Invite them to sort items by categories like color, size, shape, or texture. You can guide them by saying, “Let’s put all the smooth things here.”
  4. Discuss: Talk about each item and what they noticed. For instance, “This leaf is green, and this one is brown,” or “These rocks are smooth, and these sticks are rough.”
  5. Expand: Over time, you can compare different seasons and notice changes in the types of natural items found.
6
Toddler doing a baking soda and vinegar volcano experiment

Simple Baking Soda and Vinegar Volcano

This safe, fizzy reaction introduces chemistry and the concept of reactions.

Materials

  • Baking soda
  • Vinegar
  • Small container or cup
  • Food coloring (optional)
  • Small spoon or dropper

Steps:

  1. Set up: Place a small container on a tray. Add a little baking soda to the container.
  2. Introduce: Explain that when we add vinegar, it will cause a reaction that makes bubbles.
  3. Add vinegar: Help the child slowly add a small amount of vinegar using a dropper or small cup.
  4. Observe: Watch as the reaction fizzes and bubbles! They can add more vinegar to see the effect again.
  5. Experiment: Try adding a few drops of food coloring to the vinegar to create colorful reactions.

These activities engage a toddler’s natural curiosity and introduce scientific concepts in a Montessori-aligned, hands-on way. Each activity provides opportunities for observation, exploration, and open-ended discussion, fostering a love for learning and exploration at an early age.
