Matter | Standard Lesson
Students investigate matter as it exists, changes, and cycles through Earth’s systems. They distinguish physical and chemical properties, identify states and phase changes, and connect the conservation of matter to geologic and environmental processes.
| Term | Definition |
|---|---|
| matter | Anything that has mass and takes up space. |
| mass | The amount of matter in an object. |
| volume | The amount of space matter occupies. |
| physical property | A characteristic that can be observed or measured without changing a substance’s identity. |
| chemical property | A characteristic that describes how a substance can change into a new substance. |
| phase change | A change from one state of matter to another without changing chemical identity. |
| solid | A state of matter with definite shape and definite volume. |
| liquid | A state of matter with definite volume but no definite shape. |
| gas | A state of matter with no definite shape or volume. |
| conservation of matter | The principle that matter is not created or destroyed in ordinary physical and chemical changes. |
Display two prompts: 'What is matter?' and 'Where is matter found in Earth systems?' Circulate and note prior knowledge.
Write brief responses individually, then share one idea with a partner.
Define matter, mass, volume, and properties. Use examples from Earth science, emphasizing the difference between physical and chemical properties.
Take guided notes and answer quick oral questions.
Model a phase change using ice and water or a diagram of heating/cooling. Highlight particle motion and conservation of matter.
Observe, record observations, and identify the phase change shown.
Present examples related to Earth science (air, magma, rock, groundwater, clouds, minerals). Guide students to classify state of matter, properties, and possible changes.
Work in pairs to complete the graphic organizer and justify answers using vocabulary.
Lead groups through a short scenario set: evaporation in the water cycle, weathering of rock, combustion in a wildfire, and carbon moving through the atmosphere.
Discuss how matter changes form or location while remaining conserved; record evidence for each scenario.
Provide a short advanced-response task asking students to explain one Earth process using conservation of matter and state changes.
Write a concise CER-style response (Claim, Evidence, Reasoning) in notebooks.
Administer a 3-question exit ticket focused on matter, phase change, and conservation of matter.
Complete independently and submit before leaving.
Clarify misconceptions and preview how matter relates to energy and Earth system interactions.
Share one takeaway or remaining question.
Students summarize in one sentence how matter changes form or location in Earth systems without being created or destroyed.
Formative assessment through guided practice, group analysis, independent CER response, and a 3-question exit ticket measuring understanding of matter, state changes, and conservation of matter.
