Course Plan: Science - Matter and Interactions for Grade 7
Introduction
Welcome to the Science course on Matter and Interactions designed for 7th-grade students! In this course, students will explore the fundamental concepts of matter, its properties, interactions, and the changes it undergoes. Through a combination of inquiry-based learning, hands-on activities, discussions, and assessments, students will gain a deeper understanding of how matter exists in our world and interacts with itself and other forms of matter. This course aligns with the Next Generation Science Standards (NGSS) and aims to develop scientific literacy, critical thinking, and problem-solving skills.

Aims
- Encourage curiosity and questioning about the physical world.
- Foster collaboration and communication skills through group work.
- Promote the use of scientific practices such as inquiry, experimentation, and data analysis.
- Develop an appreciation for the relevance of science in everyday life and future learning.
Course Module Breakdown
Module 1: Introduction to Matter (Lessons 1-3)
Lesson 1: What is Matter?
- Define matter and its significance.
- Explore examples of matter in everyday life.
- Discussion on what is not matter (e.g., light, sound).
Lesson 2: States of Matter
- Identify the three primary states of matter: solids, liquids, and gases.
- Discuss the properties and examples of each state.
- Hands-on activity: Group experiment observing changes in states (e.g., melting ice).
Lesson 3: Changes in States of Matter
- Explain how matter changes states through heating and cooling.
- Illustrate phase changes: melting, freezing, evaporation, and condensation.
- Reflection activity: Journal entry on a recent phase change observed.
Module 2: Properties of Matter (Lessons 4-6)
Lesson 4: Physical Properties of Matter
- Define and identify physical properties (color, texture, density, mass, volume).
- Interactive lab: Measure and record physical properties of different substances.
Lesson 5: Chemical Properties of Matter
- Introduce chemical properties (ability to rust, flammability).
- Discuss the difference between physical and chemical changes.
- Group discussion: Identify chemical properties in household items.
Lesson 6: Measuring Matter
- Teach students how to measure mass, volume, and density.
- Activity: Use balance scales and graduated cylinders to measure different objects and liquids.
Module 3: Interactions of Matter (Lessons 7-10)
Lesson 7: Introduction to Interactions
- Discuss definitions and significance of interactions between different forms of matter.
- Activities: Explore magnets and various materials to understand attraction and friction.
Lesson 8: Forces Acting on Matter
- Identify different forces affecting matter (gravity, friction, buoyancy).
- Lab: Experiment with objects in water to understand buoyancy.
Lesson 9: Chemical Reactions
- Define chemical reactions and the changes that occur during these processes.
- Hands-on experiment: Observe a simple reaction (e.g., vinegar and baking soda) and identify signs of chemical change.
Lesson 10: Conservation of Mass
- Introduce the law of conservation of mass.
- Conduct an experiment to demonstrate that mass is conserved in a reaction.
Module 4: Applications of Matter (Lessons 11-15)
Lesson 11: Mixtures and Solutions
- Differentiate between mixtures and solutions.
- Activity: Create and categorize various mixtures (e.g., sand and salt).
Lesson 12: Properties of Solutions
- Discuss solubility and factors affecting it (temperature, agitation).
- Lab: Test solubility of different substances in water at varying temperatures.
Lesson 13: Properties of Acids and Bases
- Introduce acids and bases and their properties.
- Experiment: Use pH indicators to test various household substances.
Lesson 14: Practical Applications of Matter
- Discuss real-life applications of the concepts learned (e.g., cooking, cleaning).
- Group project: Research and present on a product that relies on specific materials or reactions.
Lesson 15: Review and Assessment
- Review key concepts from the course.
- Administer a formative assessment (quizzes, group discussion, and projects).
- Reflection and feedback on the learning experience.
Conclusion
At the end of this course, students will have a solid grasp of matter and its interactions. They will not only understand the theoretical aspects but also appreciate the practical implications of these concepts in real life. Our journey through the world of matter will empower students with the knowledge and skills to question, explore, and understand their physical environment.
