This grade 6–8 reading introduces students to the science behind why roads are salted in winter and how salt helps melt ice to make roads safer. Students learn how water freezes, why icy roads are dangerous, and how adding salt changes the freezing point of water through a process called freezing point depression.

The article explains concepts such as physical changes, particle behavior, freezing point depression, friction, and traction in clear, student-friendly language. Students explore real-world examples including why salted roads are less slippery, how sand and brine are used alongside salt, and how environmental concerns influence winter road management. This resource is perfect for physical science, chemistry, Earth science, weather, and general science classes and supports both content learning and scientific literacy skills.

This resource covers the following topics:

• How Water Freezes
• Freezing Point and Freezing Point Depression
• Physical Changes vs. Chemical Changes
• How Salt Melts Ice
• Particle Motion and Energy
• Friction and Traction on Icy Roads
• Sand, Brine, and Alternative De-icers
• Real-World Uses of Road Salt
• Environmental Impacts of Road Salt
• Balancing Safety and Environmental Protection

✅ Grade 6–8 Reading on Freezing Point Depression: How salt changes freezing temperatures and improves road safety.

Praise For My Other Reading Comprehension Resources:

• "I teach middle school science and need to include informational text in my classroom. These readings are great for independent reading for my grade-level and upper-level readers. The articles address CCSS.ELA-Literacy.RST.6-8.1 (Citing specific textual evidence to support analysis of science and technical texts.) and CCSS.ELA-Literacy.RST.6-8.10 (By the end of grade 8, read and comprehend science/technical texts in the grades 6-8 text complexity band independently and proficiently.). The leveled questions allow you to subtly assign the questions to different ability students working in a group."
• Topics are relevant to the students and current. Graphics draw the students into the article. I'm going to have one printed and waiting in for my substitute folder too!"
• "THANKS!"
• "Thanks for putting together a wonderful resource."
• "I teach Special Education high school science in Maryland in a special school for children with learning disabilities/Autism. I liked the readings and I think students could relate to the topics.

We don't spend enough time teaching scientific literacy to our students. This is either because we don't have the resources to do so effectively or we don't have the time. However, teaching our students to become scientifically literate is vital if we want them to succeed in life. We need them to know about the world they live in and about the issues they face.
