Overview

Matter and Energy in Grade 7 Science (TEKS) strengthens students’ understanding of how matter is organized, how energy moves, and how change can be explained using evidence. This Lesson Bundle includes 10 TEKS-aligned worksheets that connect models, observations, and scientific reasoning for a focused unit on matter and energy.

What's Included

• ✅ Grade 7 Science | Properties and Classification Worksheet | TEKS-Aligned – Students practice describing properties of matter and using classification criteria to organize substances.
• ✅ Grade 7 Science | Energy Transfer Worksheet | TEKS-Aligned – Students analyze how energy transfers through processes and relate energy changes to observable effects.
• ✅ Grade 7 Science | Atomic Structure Worksheet | TEKS Alligned – Students connect atomic structure to how matter is represented and explain basic subatomic features.
• ✅ Grade 7 Science | States Of Matter Worksheet | TEKS-Aligned – Students compare solid, liquid, and gas states using particle and macroscopic evidence.
• ✅ Grade 7 Science | Reaction Evidence Worksheet | TEKS-Aligned – Students evaluate evidence for chemical reactions and distinguish changes that indicate new substances.
• ✅ Grade 7 Science | Particle Model Worksheet | TEKS Alligned – Students use particle models to represent matter behavior and justify claims with model evidence.
• ✅ Grade 7 Science | Mixtures Separation Worksheet | TEKS Alligned – Students apply separation methods to demonstrate how mixtures can be separated based on properties.
• ✅ Grade 7 Science | Gas Behavior Worksheet | TEKS-Aligned – Students explain gas behavior using particle motion and relationships between variables.
• ✅ Grade 7 Science | Conservation of Mass Worksheet | TEKS-Aligned – Students use conservation of mass reasoning to interpret changes during physical and chemical processes.
• ✅ Grade 7 Science | Bonding Patterns Worksheet | TEKS-Aligned – Students examine bonding patterns and connect them to structures and how substances form.

Skills & Standards

Across the Matter and Energy unit in the TEKS framework, students build skills in modeling, analytical reasoning, and evidence-based explanation. They learn to interpret particle models to describe properties, state changes, and gas behavior; use atomic structure ideas to support representations of matter; and connect bonding patterns to how substances form. Students also practice evaluating reaction evidence by examining what observations count as evidence of new substances, and they apply conservation of mass reasoning to explain why total mass remains constant during interactions. Throughout, learners strengthen crosscutting abilities such as using scientific models to make predictions, analyzing patterns in data and observations, and constructing explanations that incorporate evidence rather than relying on intuition.

How to Use

Plan this Matter and Energy unit for a typical 1–3 week sequence, depending on pacing and class schedules. Use a quick warm-up each day to review prior models or vocabulary (for example, particle motion, energy transfer, or conservation of mass). Follow worksheets with guided practice that includes teacher-led modeling and short student discussions, then use exit tickets to check for evidence-based explanations (e.g., “What observation would count as reaction evidence?”). Finish with an end-of-unit review that blends one task from each major idea area: classification and properties, atomic/particle models, energy and reactions, and conservation and bonding.

Closing

These ready-to-use resources support clear, TEKS-aligned instruction so students can explain how matter and energy interact using models and evidence.
