Ice & Snow

Mastery Evidence

• Explain that ice and snow are frozen water (solid) and that water can change between solid and liquid
• Describe an iceberg as a huge piece of ice floating in the ocean with most of it hidden below the surface
• State that ice floats because frozen water is lighter than liquid water

Assessment Prompt

“Does [child] know that icebergs are like floating ice mountains with most of the ice hidden under the water — and that the polar regions are covered in ice because it's so cold the water stays frozen?”
