Chemical Reactions Science Unit for 4th & 5th Grade

Bring the excitement of science into your classroom with this hands-on unit all about chemical reactions! This no-prep resource helps students explore how matter changes through interactive lessons, simple experiments, and kid-friendly nonfiction content.

Teaching chemical reactions doesn’t have to feel intimidating or messy. This 10-day NGSS-aligned unit gives you everything you need to spark curiosity and help students build a clear understanding of physical vs. chemical changes.

Teachers often struggle to:

• Clearly explain the difference between physical and chemical changes in a student-friendly way
• Help students identify evidence of chemical reactions, such as bubbling, color change, temperature shifts, or the formation of a new substance
• Teach the concept of reversible vs. irreversible changes in a way that sticks
• Show how heating, cooling, and mixing can change matter through engaging, hands-on experiences
• Encourage students to use accurate scientific vocabulary in both writing and class discussions
• Guide students in making detailed observations and building explanations based on evidence

Our Chemical Reactions Unit solves common teaching challenges with thoughtfully designed resources that make science fun and meaningful. With PowerPoints, reading passages, stations, and an assessment, students will learn key vocabulary, investigate real-life reactions, and apply their learning in engaging ways.
