Lesson Duration
45 minutes per day for 5 days
Learning Objectives
- Students will be able to understand the concept of physical changes and chemical changes.
- Students will be able to identify the differences between physical changes and chemical changes by conducting experiments.
- Students will be able to differentiate mixtures from compounds and elements.
- Students will be able to explain the properties of solids, liquids, and gases and how they can be changed through physical and chemical changes.
Day 1
Do Now (5 minutes)
- Students will be asked to write down a physical change and a chemical change that they have observed or experienced in their daily lives.
Mini Lesson (10 minutes)
- Introduction to physical changes and chemical changes
- Importance of understanding the differences between the two
Practice (25 minutes)
- Students will be divided into pairs to conduct experiments to determine if the changes they observe are physical or chemical.
- Each pair will be given a list of materials and instructions for the experiment.
- Students will record their observations and discuss their findings with the class.
Exit Ticket (5 minutes)
- Students will answer a few questions about the experiment and their understanding of physical and chemical changes.
Day 2
Do Now (5 minutes)
- Students will be asked to differentiate mixtures from compounds and elements.
Mini Lesson (10 minutes)
- Introduction to mixtures, compounds, and elements
- Explanation of how they differ from physical and chemical changes
Practice (25 minutes)
- Students will be given different substances to classify as mixtures, compounds, or elements.
- Each student will also be asked to explain their reasoning behind their classification.
- Students will share their findings with the class.
Exit Ticket (5 minutes)
- Students will answer a few questions about mixtures, compounds, and elements.
Day 3
Do Now (5 minutes)
- Students will be asked to name the three states of matter and give examples of each.
Mini Lesson (10 minutes)
- Properties of solids, liquids, and gases
- Explanation of how they can be changed through physical and chemical changes
Practice (25 minutes)
- Students will observe the change of state of water through different methods.
- Each pair will be asked to explain their observations and how they can be classified as physical or chemical changes.
- Students will share their findings with the class.
Exit Ticket (5 minutes)
- Students will answer a few questions about the properties of solids, liquids, and gases.
Day 4
Do Now (5 minutes)
- Students will be asked to give examples of physical and chemical changes that affect the environment.
Mini Lesson (10 minutes)
- The impact of physical and chemical changes on the environment
- Discussions on ways to reduce the negative effects
Practice (25 minutes)
- Students will be asked to come up with a project that involves reducing the negative effects of physical and chemical changes on the environment.
- Each group will present their project to the class.
Exit Ticket (5 minutes)
- Students will answer a few questions about the impact of physical and chemical changes on the environment.
Day 5
Do Now (5 minutes)
- Students will be asked to reflect on what they have learned in the past 4 days.
Mini Lesson (10 minutes)
- Review of the concepts learned in the past 4 days
Practice (25 minutes)
- Students will be given an activity to reinforce the concepts learned in the past 4 days.
- Each student will be asked to explain their answers.
Exit Ticket (5 minutes)
- Students will answer a few questions about what they have learned in the past 5 days.
