Solids & Liquids — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Water in the freezer slowly turns to ice.
The freezer is cold enough to change liquid water into solid ice cubes.
2. Butter in a warm pan starts to melt.
Heat from the pan changes solid butter into a liquid that flows around.
3. An ice cream cone left in the sun will melt.
The hot sun warms the ice cream and changes the solid into a sticky liquid.
4. Juice in a pop mold will freeze into a pop.
Cold air in the freezer pulls heat from the juice, so it turns into a solid pop.
5. Chocolate held in your warm hand can melt.
Body heat is enough to change solid chocolate into a soft, gooey liquid.
6. To freeze something, we make it very cold.
Freezing needs lots of cold air to change a liquid into a solid block.
7. To melt something, we add some heat.
Heat changes a solid into a liquid, which is exactly what melting means.
8. A melted popsicle becomes sticky juice.
When the frozen solid warms up, it goes back to being a liquid again.
9. Water that freezes takes the shape of its tray.
Liquid water fits the tray first, then freezes into that exact cube shape.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
juice in a pop mold
→ freezes solid
freezes solid
butter on a hot pan
→ melts to liquid
melts to liquid
chocolate in a warm hand
→ melts soft and gooey

ice cream in the sun
→ drips into a puddle
drips into a puddle
Cold places freeze liquids into solids, while warm places melt solids back into flowing liquids.
