Year-7 Chemistry Chemical Reactions: Conservation of Mass
In this Year-7 Chemistry Chemical Reactions: Conservation of Mass lesson, students will learn what conservation of mass is, how to calculate the masses of reactants and products and how to balance simple chemical equations.
The slides include extension questions, and students can choose from a variety of different tasks.
This lesson includes:
- Title slide with learning objectives
- Starter task
- Group reading (literacy)
- Keywords (vocabulary: conservation, mass, conservation of mass and balanced)
- Task boxes
- Calculating masses numeracy task
- Problem solving (why the mass appears to decrease when a gas is formed) discussion exercise
- Balancing equations walk-through
- Balancing equations practice questions
