Ice Melting Experience

1409 Words6 Pages
Experience 1: For children to experience the solid form of water, and to understand freezing and melting process. This experience helps children to see the relationship between ice and water. It support children to understand temperature can make water change its form, and for children to recognize the term solid, freezing and melting.
Activity Title: Ice making and ice dig activity
Resource and Equipment:
Equipment to make the ice block: • Stones
• Plastic crystals
• Shells
• Jag
• Toy dinosaurs • Large container (e.g. ice cream container)
Resource and equipment set up the ice play area: • Salt (with few drop of blue food colour)
• a shaker container for the salt x3
• plastic pate spreaders x5
• syringes without the needle x5

Encourage children to making contraption out of the pipes, and play around with water with different equipment. Stimulate children’s thinking by asking questions, such as “what is water like?” “How does it feel?” Then explain the property of “liquid”.
5. Next, pop out the coloured ice cube into the water tough, and emphasis children’s previous learning on “solid”, by asking children: “what do you think this is?”
6. After, measure the temperature of water with ice cube again, and ask children “Do you think the water will stay the same or it will change? Why?” to reinforce children’s learning on “freezing”, “melting” and “constancy and change”.
7. When the ice melted in the liquid water, use the thermometer to measure the temperature of the water to give evidence for those concept.
8. To extent children’s learning, educator can also explained to the children why does the ice (solid water) float on the liquid water, and introduce the concept of “density” and how its’ different to “mass”. After, explain that the ice (solid water) has lower density then water (liquid water). Educator can also read the picture book “who sink the boat” by Pamela Allen to help children understand such

Description of activity:
1. Recall the previous experience with children to review the concept that the temperature helped water change forms. Then talk through the process of cloud- making experiment with children.
2. Boil the kettle. While boil the kettle, shows children the jar and the lid (or the glass cup and the small potpie pan), and let them examine it to be ensure that it is dry and free of holes.
3. Pour about quarter to one-third of hot water into the jar/glass, and let children to feel the warm temperature in the jar in a safe distance. If the side of the jar/glass is cold, use the spoon to swirl the hot water to heats it up.
4. Next, help children to fill the lid/small potpie pan with ice or ice pack, and allows the children to feel the temperature below it. (if use the lid, turned the lid upside down to use it as a container)
5. Then put it on top of the jar/glass to cover it, and rest it for around one to five
