About this reader

This science reading passage, titled 'The Freezing Point of Water', introduces students to a key physical science concept: the freezing point of water. It explains that water freezes at 0 degrees Celsius and describes the physical change that occurs as water turns from a liquid to a solid. The passage also connects this concept to real-life examples like freezing water in a freezer and icy roads in winter. It supports student learning aligned to science standards such as MS-PS1-4 (develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance) and reading informational text standards such as RI.6.1 (cite textual evidence to support analysis). Keywords like 'freezing point', '0 degrees Celsius', 'states of matter', and 'middle school science' make this resource ideal for both classroom use and SEO discoverability. With a Flesch Reading Ease score around 70, the passage is accessible for middle-grade readers and includes 8 comprehension questions that assess main idea, vocabulary, and scientific understanding. This resource is valuable for integrating science and literacy instruction while building background knowledge in physical science.

CONTENT PREVIEW

What Is the Freezing Point?

Water turns from a liquid into a solid at a special temperature called the freezing point. For water, this is exactly 32°F (degrees Fahrenheit) or 0°C (degrees Celsius) under normal conditions. At this temperature, liquid water becomes solid ice!

What Happens to Water Molecules?

Water is made of tiny particles called molecules. These molecules are always moving around when water is a liquid. As the temperature drops, the molecules slow down. At the freezing point, the molecules move so slowly that they lock into a neat, crystal pattern and form solid ice.

Freezing Point Is Like Water’s Bedtime

Think of the freezing point as water’s bedtime. At 32°F (0°C), the water molecules get so tired and slow that they stop running around and “lie down” in an organized ice crystal pattern.

Melting Point and Freezing Point

The melting point of ice is the same as the freezing point of water. This means that ice melts and water freezes at 32°F (0°C). The process works both ways!

Why Does the Freezing Point Matter?

Knowing about the freezing point is important in real life. Weather reports warn people when temperatures are at or below freezing, so drivers can be careful about ice on roads. Farmers protect plants from frost. In winter, pipes in homes can burst if water inside them freezes and expands.

Water’s Wacky Fact

Unlike most liquids, water expands (gets bigger) when it freezes. That’s why ice floats in water and frozen water bottles bulge!

Everyday Connections

Ice skating rinks keep the ice at just the right freezing temperature. Freezers are set colder than 32°F. Many animals survive winter because ice floats, making a safe layer over pond water.

Try It Yourself!

Put a cup of water in the freezer. Use a thermometer to check as it cools. Watch what happens at 32°F (0°C)!

Interesting Fact: Some fish and frogs can live all winter in frozen ponds because the ice floats and keeps the water underneath from freezing solid!

At what temperature does water freeze?

32°F or 0°C100°F or 50°C10°F or -12°C212°F or 100°C

What happens to water molecules as it cools?

They move slowerThey disappearThey speed upThey turn into gas

Why do pipes burst in winter?

Water expands when freezingIce shrinks pipesPipes get too hotAir freezes in pipes
