Notes for adults

Age 1 · 5 min · Easy

A short sensory activity to touch ice, watch colored water, and discover what happens when colors mix.

Learning objectives

• Explore ice or water by briefly touching or pointing.
• Notice a change in the ice or colored water.
• Show interest through gestures, sounds, or words.

What you need

• A wide, shallow tray
• Water
• Food coloring in two colors
• Two large containers for freezing the water
• A towel to dry hands and the surface

Safety notes

An adult must supervise closely throughout and never leave the child alone with water or ice. Use only food-grade coloring and check for allergies and sensitivities; do not use regular paint. Make blocks too large to fit in the child's mouth, and remove them before they become small enough to fit. Do not let the child put ice in their mouth. If they try, hold the ice yourself and let them touch only the melted water. Offer only brief touches to avoid discomfort from the cold, and stop if the child does not want to continue. Discard the water when finished.

How to do it

1. Before playtime, freeze water with a little food coloring in two large containers, using one color in each.
2. Place the tray on a stable surface and settle your child close beside you.
3. Remove the blocks from the containers and place them on the tray. Say, “Look at the colorful ice!”
4. Briefly touch one block and describe how cold it feels.
5. Invite your child to touch the ice for a moment or point to it. Keep the blocks within your reach.
6. Watch the ice melt, then gently tilt the tray to bring the colors together.
7. When you finish, remove the ice, discard the water, and dry your child's hands.

Teaching suggestions

• Use simple phrases such as “It's cold” and “The water turned purple.”
• Accept looks, gestures, and sounds as responses; your child does not need to speak.
• If your child does not want to touch, let them watch you move the tray.
• Connect the discovery to the water your child sees when washing their hands.

Variations

• Make it easier: Use one block in a single color. Your child can simply watch or touch the melted water.
• Make it more challenging: Show the two colors separately, then invite your child to point to the water after the colors mix.
• Explore more: Another time, watch some uncolored ice melt on the tray together.

Talk about it

• What do you see?
• How does the ice feel?
• What happened to the water?
• What color is it now?

What to look for

• Notice whether your child points to, looks at, or briefly touches the ice or water.
• Notice whether your child watches the ice melt or the colors mix.
• Look for gestures, sounds, or words that show interest.
