Ice, Water, and Steam: A Heat Adventure

Materials Needed

• Several ice cubes
• Two clear cups or bowls
• Small saucepan or kettle, used only by an adult
• Water
• Oven mitt or thick towel
• Tray or towel for spills
• Paper and crayons
• Three simple labels: Solid, Liquid, and Gas
• Optional: timer, magnifying glass, and a camera for recording observations

Learning Objectives

By the end of the lesson, the child will be able to:

• Name the three states of water: solid, liquid, and gas.
• Explain in simple words that heat can change ice into water and water into steam.
• Use the steps of the scientific method: ask, predict, observe, and share.
• Describe at least one change noticed during the experiment.
• Sort or match examples of solid, liquid, and gas.

Success Criteria

The child is successful when they can:

• Say, “Ice is a solid, water is a liquid, and steam is a gas.”
• Make a prediction before an experiment.
• Use one or more senses safely to observe changes.
• Draw or tell what happened.

Important Safety Note

An adult must handle the hot pan, kettle, and steam. The child should never touch hot water, the pan, or steam. Keep the child several steps away from the heat source. Use words such as, “Steam is hot. We look with our eyes, but we do not touch.”

Introduction: The Ice Mystery

Hook

Show the child an ice cube and ask:

• “What do you think will happen to this ice cube if we leave it in a warm place?”
• “Can ice become water?”
• “Can water become something we cannot hold?”

Say: “Today we are going to be water scientists. We will watch ice, water, and steam change.”

Tell the Learner What They Will Learn

Say: “We will learn that water can be a solid, a liquid, or a gas. Heat helps water change from one state to another.”

Part 1: Meet the Three States of Water

Solid: Ice

Give the child an ice cube to look at and touch briefly.

Say: “Ice is water that is frozen. It is a solid. A solid keeps its shape.”

Ask:

• “Does the ice cube keep its shape?”
• “Is it hard or runny?”

Liquid: Water

Pour water into a clear cup.

Say: “Water is a liquid. A liquid can flow and takes the shape of its container.”

Pour the water into a different-shaped cup, if available.

Ask: “Did the water change shape when it moved to the new cup?”

Gas: Steam

With the child watching from a safe distance, have an adult heat water until steam rises.

Say: “Steam is water that has become a gas because of heat. Gas spreads out and is hard to hold.”

Ask: “Can we hold steam in our hands? How can we see it?”

Part 2: The Scientific Method

Explain that scientists ask questions, make guesses, watch carefully, and share what they find. Use these child-friendly words:

1. Ask: What do we want to find out?
2. Predict: What do we think will happen?
3. Test: What can we do to find out?
4. Observe: What do we see, feel, or hear safely?
5. Share: What happened?

Part 3: I Do — Adult Demonstration

Investigation 1: Heat Turns Ice into Water

1. Place an ice cube in a clear cup or bowl.
2. Ask the child to make a prediction: “Will the ice stay the same, or will it change?”
3. Place the cup in a warm room or sunny spot, away from danger.
4. Invite the child to observe every few minutes.
5. Point out that the ice becomes smaller and water appears.

Say: “The ice is getting heat from the room. The heat is helping the solid ice change into liquid water.”

Quick Check

Ask the child to complete the sentence:

“Heat turns ice into ______.”

Expected answer: water.

Part 4: We Do — Test Water and Steam Together

Investigation 2: Heat Turns Water into Steam

1. Pour a small amount of water into a saucepan or kettle.
2. Ask the child: “What do you predict will happen when the water gets very hot?”
3. An adult heats the water while the child watches from a safe distance.
4. When steam rises, turn off the heat.
5. Ask the child to describe what they noticed.

Use simple language: “The heat made the liquid water change into a gas called steam.”

Safe Observation Questions

• “What did you see above the water?”
• “Did the water move or stay still?”
• “Was the steam safe to touch?”
• “What did the heat do?”

Quick Check

Ask the child to complete the sentence:

“Heat turns water into ______.”

Expected answer: steam.

Part 5: You Do — Young Scientist Investigation

Choose One Investigation

Let the child choose one activity.

Choice A: Watch an Ice Cube Melt

1. Draw an ice cube on paper.
2. Ask: “What do you predict will happen?”
3. Check the ice every few minutes.
4. Draw what the ice looks like at the beginning and at the end.

Choice B: Compare Warm and Cool Places

1. Place one ice cube in a warm room and one ice cube in a cooler place.
2. Ask: “Which ice cube will melt first?”
3. Observe both ice cubes.
4. Talk about how the warmer place gives the ice more heat.

Choice C: Act Out the Water Changes

• Stand still and hold your body tightly together to act like a solid.
• Move slowly around the room to act like a liquid.
• Stretch your arms and move freely to act like a gas.

Say the state aloud as the child acts it out: “Solid! Liquid! Gas!”

Scientific Method Recording Page

The child may draw pictures or answer orally. Write down the child’s words if needed.

Science Step	Child’s Answer or Drawing
Ask: What are we finding out?	How heat changes water.
Predict: What do you think will happen?	________________________________________________
Observe: What did you see?	________________________________________________
Share: What happened?	________________________________________________

Interactive Sorting Game

Place the labels Solid, Liquid, and Gas on the floor or table. Say or show examples, and ask the child to place each one under the correct label.

• Ice cube — solid
• Water in a cup — liquid
• Steam above hot water — gas
• Frozen popsicle — solid
• Juice — liquid
• Air — gas

For an added challenge, ask: “What helps ice become water?” and “What helps water become steam?”

Real-World Connections

Talk about places where the child may see water change:

• Ice melting in a drink
• A frozen popsicle melting on a warm day
• Water boiling to cook pasta
• Steam rising from a warm bath
• Clouds forming from water in the air

Formative Assessment During the Lesson

Check understanding by asking the child to:

• Point to the solid, liquid, and gas labels.
• Tell what happens to ice when it gets warm.
• Tell what happens to water when it gets very hot.
• Make a prediction before an observation.
• Describe one change using the words heat, ice, water, or steam.

Summative Assessment: Show What You Know

Ask the child to complete one of these demonstrations:

• Draw three pictures labeled solid, liquid, and gas.
• Use an ice cube, a cup of water, and a pretend cloud of steam to explain the changes.
• Tell a short story: “First there was ice. Then heat made it become water. More heat made the water become steam.”

Simple Assessment Checklist

• Names ice as a solid.
• Names water as a liquid.
• Names steam as a gas.
• Explains that heat changes ice into water.
• Explains that heat changes water into steam.
• Uses at least two steps of the scientific method.

Differentiation and Adaptations

For a Child Who Needs More Support

• Use only the words ice, water, and steam at first.
• Offer sentence starters: “I see...,” “I think...,” and “Heat makes...”
• Use gestures: hold still for solid, wave hands for liquid, and spread arms for gas.
• Allow the child to answer by pointing, drawing, or acting instead of speaking.

For a Child Ready for More

• Ask the child to explain why ice melts faster in a warm place.
• Measure how long two ice cubes take to melt.
• Ask what might happen when steam touches a cool surface.
• Introduce the word condensation by showing water droplets that form on the outside of a cold cup.

Flexible Learning Options

• Hands-on: Observe melting ice and rising steam.
• Movement-based: Act out solid, liquid, and gas.
• Art-based: Draw the three states of water.
• Digital: Record a short video of the child explaining the changes, without showing hot equipment close up.
• Conversation-based: Discuss examples from cooking, weather, and daily life.

Conclusion: Tell What We Learned

Review the lesson with the child:

• “Ice is a solid.”
• “Water is a liquid.”
• “Steam is a gas.”
• “Heat can turn ice into water.”
• “More heat can turn water into steam.”
• “Scientists ask, predict, observe, and share.”

Exit Question

Ask: “If you put an ice cube in a warm cup, what will happen, and why?”

Finish by saying: “You were a scientist today. You asked a question, made a prediction, watched carefully, and shared what you discovered.”
