Five Senses Apple Investigation

The five senses are a great way for young children to practice observation skills.

Provide several varieties of apples and invite children to explore them using sight, smell, touch, taste, and hearing. Listen for the crunch when biting into the apple, feel the skin, and compare the smell and taste of different types.

👉 This activity encourages kids to observe carefully and describe differences.

Magic Milk Experiment

This colorful science activity demonstrates how soap interacts with milk.

Add drops of food coloring to a shallow dish of milk. Touch the milk with a drop of dish soap and watch the colors swirl and move.

👉 Kids observe how the soap changes the surface of the milk, creating exciting patterns.

Dancing Raisins Experiment

Can raisins really dance?

Add raisins to a glass of clear soda or sparkling water and watch what happens. Tiny bubbles attach to the raisins and lift them to the surface. When the bubbles pop, the raisins sink again.

👉Kids can observe this repeating pattern and watch the raisins appear to dance.

Pin

Sink or Float Investigation

Gather everyday objects and test whether they sink or float in water.

Encourage kids to predict what will happen before placing each object into the water. Compare different materials and discuss what they notice.

👉 This investigation introduces kids to ideas about buoyancy and materials.

Walking Water Rainbow Experiment

Set up several cups filled with colored water and connect them with folded paper towels.

Over time, the water travels through the paper towels and moves into the empty cups, mixing colors along the way.

👉 Kids can observe how water moves and how colors combine.

Pin

Egg in Salt Water

Will an egg float or sink?

Place an egg in a glass of plain water and observe what happens. Then add salt to the water and try again.

👉 Kids can compare how the egg behaves in different types of water.

Oobleck

Is it a liquid or a solid?

Oobleck is made from cornstarch and water and behaves like both. When squeezed, it feels solid, but when poured, it flows like a liquid.

👉 Kids can explore how this unusual material changes depending on how it is handled.

Pin

Magnet Discovery Table

Magnets provide wonderful opportunities for exploration.

Provide magnets along with objects made from different materials, such as paper clips, coins, plastic items, and wooden blocks. Kids can test which objects are attracted to magnets.

👉 This investigation introduces basic ideas about magnetic force.

Mirrors and Reflection

Mirrors create exciting opportunities to explore light.

👉 Kids can experiment with mirrors to observe reflections and see how light bounces off surfaces. Try changing the angle of the mirror and noticing how the reflection moves.

Pin

Colored Carnations

Place white carnations in glasses of colored water and observe what happens over time.

As the flowers absorb water, the petals begin to change color. This demonstrates how plants move water through their stems.

👉 You can also try this experiment using celery.

Rain Cloud in a Jar

Where does rain come from?

Fill a jar with water and add a layer of shaving cream on top to represent a cloud. Slowly drip colored water onto the cloud and watch it begin to fall through like rain.

👉 This simple experiment introduces basic weather science concepts.

Seed Germination Jar

Place seeds inside a jar lined with a damp paper towel so children can observe them sprouting.

👉 This setup allows kids to see the roots and shoots develop as the seed begins to grow.

Pin

Rainbow Light Experiment

Use a prism or a glass of water to explore how white light can separate into rainbow colors.

👉 Kids can observe how light bends and spreads into different colors.

Shadow Tracking Experiment

Go outside and trace a shadow with chalk. Return later in the day and trace the shadow again. Compare how the shadow has changed position.

👉 This simple investigation helps children observe patterns in the Sun’s movement.

Ice Melt Investigation

Ice is an excellent material for science exploration.

Observe how ice melts over time, and test different ways to melt it faster using warm water, salt, or tools like droppers and basters.

👉 Kids can compare which method melts the ice the fastest.

What Absorbs Water?

Test different materials to see which ones absorb water.

Try materials such as paper towels, sponges, cloth, foil, and plastic. Place water on each material and observe what happens.

👉 Kids can compare which materials soak up water and which repel it.

Pin

What Melts Investigation

Explore how heat changes materials.

Place small items such as chocolate, butter, crayons, or ice in the sun or near a warm window. Observe which materials melt and which remain unchanged.

👉 Encourage kids to make predictions before observing the results.

Static Electricity Balloon Experiment

Rub a balloon on hair or wool and bring it close to small pieces of paper or pepper. The pieces may jump toward the balloon as the balloon becomes charged with static electricity.

👉 Kids can also observe how the balloon can bend a thin stream of water.

Pin

Pepper and Soap Experiment

Sprinkle black pepper onto the surface of a bowl of water. When a drop of dish soap touches the water, the pepper quickly moves away.

👉 Kids observe how soap changes the surface of the water.

Color Mixing Experiment

Fill cups with red, blue, and yellow colored water. Mix small amounts together to see how new colors form.

👉 Kids can observe how primary colors combine to create secondary colors.

Rubber Band Sound Experiment

Stretch rubber bands around a small box or container and pluck them.

👉 Kids can observe how the rubber bands vibrate and produce sound. Try using rubber bands with different thicknesses to compare the sounds they make.
