Changing Materials: Mixing
Students explore how mixing different materials can create new substances with new properties.
Key Questions
- Analyze what happens when two different materials are mixed together.
- Differentiate between a mixture and a new substance formed by mixing.
- Design an experiment to create a new material by mixing.
Common Core State Standards
About This Topic
Inventors and Creators explores the Americans whose ideas and inventions changed the way we live. By studying figures like Thomas Edison (lightbulb) and the Wright Brothers (airplane), students learn about the process of problem-solving, persistence, and innovation.
This topic aligns with history and economics standards regarding technology and its impact on society. It encourages students to see themselves as 'problem-solvers' and to think about how they can use their own creativity to help others. This topic is most engaging when students can participate in 'invention challenges' where they must design a solution to a common classroom problem.
Active Learning Ideas
Inquiry Circle: The Invention Timeline
In small groups, students look at pictures of an invention (like a phone) from different times. They must put them in order and discuss how each new version solved a problem that the old one had.
Simulation Game: The Invention Lab
Students are given a 'problem' (e.g., 'How can we keep our pencils from rolling off our desks?'). They use recycled materials to build a prototype of an invention that solves the problem and then present it to the class.
Think-Pair-Share: What's Next?
Students think of one thing they wish existed to make their life easier (like a robot that cleans their room). They share their idea with a partner and explain how it would work and who it would help.
Watch Out for These Misconceptions
Common MisconceptionInventors always get it right the first time.
What to Teach Instead
Emphasize the importance of 'failing forward.' Tell the story of how many times Edison tried to make the lightbulb before it worked. Active 'persistence' games can help students realize that mistakes are just part of the learning process.
Common MisconceptionInventions are only 'high-tech' things like computers.
What to Teach Instead
Show students that simple things like a zipper, a paperclip, or a wheel are also inventions. Active 'invention hunts' in the classroom can help them see that almost everything they use was once someone's new idea.

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: Heating and Cooling
Students investigate how heating and cooling can change the properties of some materials.

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).
