Sorting Objects by Properties – Science Lesson for Kindergarten

Why Do We Sort Things?

Sorting means putting things in groups based on how they are alike or different.

We sort objects by their properties , like:

• hardness
• texture (smooth or rough)
• weight (heavy or light)
• flexibility (bendy or stiff)

This helps us understand how things are similar or different.

Example: Sorting by Texture

Imagine you have 4 objects:

• A wooden block – hard and rough
• A sponge – soft and flexible
• A metal spoon – hard and smooth
• A cotton ball – soft and light

You could sort them into two groups:

• Soft : sponge, cotton ball
• Hard : wooden block, metal spoon

Or by texture:

• Smooth : metal spoon, cotton ball
• Rough : wooden block, sponge
