Changing Materials: Heating and Cooling
Students investigate how heating and cooling can change the properties of some materials.
Key Questions
- Explain how heating can change the state or properties of a material.
- Compare the effects of heating and cooling on different substances.
- Predict what might happen to a material if it is heated or cooled significantly.
Common Core State Standards
About This Topic
Leaders for Change focuses on individuals who worked to make the United States a fairer place for everyone. By studying leaders like Dr. Martin Luther King Jr. and Rosa Parks, students learn about the power of peaceful protest and the importance of standing up for what is right.
This topic aligns with civics and history standards regarding civil rights and democratic values. It helps students understand that laws can be changed if they are unfair and that every person has the power to make a difference. This topic is most effective when students can engage in 'fairness' simulations and structured discussions about how to solve problems in their own community.
Active Learning Ideas
Simulation Game: The Fairness Test
The teacher gives only students wearing blue shirts a special privilege (like extra recess). The class then discusses how this feels and how it relates to the unfair laws that Dr. King and Rosa Parks worked to change.
Inquiry Circle: The 'I Have a Dream' Mural
In small groups, students discuss one thing they would like to change to make their school or neighborhood fairer. They draw their 'dream' on a large piece of paper and then combine them to create a class mural of change.
Think-Pair-Share: Standing Up
Students think of a time they saw something unfair. They share with a partner and brainstorm one peaceful way they could have helped, just like the leaders they are studying.
Watch Out for These Misconceptions
Common MisconceptionDr. King 'fixed' everything and now everything is fair.
What to Teach Instead
Explain that while Dr. King made things much better, we still have to work every day to be kind and fair to everyone. Active 'kindness challenges' can show students that being a leader for change is an ongoing job for everyone.
Common MisconceptionRosa Parks was just 'tired' when she sat on the bus.
What to Teach Instead
Clarify that she was a brave leader who made a choice to stand up for what was right. Active role-playing of her decision can help students understand the courage it took to challenge an unfair law on purpose.

Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.

Observing Material Properties
Students observe and describe the physical properties of various materials (e.g., color, texture, hardness, flexibility).

Sorting Materials by Properties
Students sort and group materials based on shared observable properties.

Changing Materials: Mixing
Students explore how mixing different materials can create new substances with new properties.

Making and Unmaking Simple Changes
Students explore simple changes to materials that can be easily undone (like bending paper) and those that are harder to undo (like tearing paper).
