| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

Chemistry
Mixtures and Solutions
Year 7
30 minutes
20 students
This lesson corresponds to the national curriculum for Year 7 Science, focusing on the properties and changes of materials and the classification of substances.
| Step Number | Step Title | Length (minutes) | Details |
|---|---|---|---|
| 1 | Introduction to Mixtures | 5 | Briefly explain what mixtures and solutions are. Provide real-life examples. |
| 2 | Discussion and Examples | 10 | Engage students in a discussion about mixtures and solutions. Ask for examples from their lives. |
| 3 | Handout and Card Activity | 7 | Distribute printable cards to students. Instruct them to fill in examples of mixtures and solutions they know. |
| 4 | Group Activity | 5 | Students work in pairs to compare their examples and discuss the differences between mixtures and solutions. |
| 5 | Collection and Random Check | 3 | Randomly collect or check the cards completed by students to assess understanding. |
| 6 | Wrap Up and Summary | 5 | Summarize the key points of the lesson and clarify any remaining questions. |
Assign students to find one example of a mixture and one example of a solution from their home environment and write a short paragraph explaining each. Students will submit their homework via a digital platform without presentations in class.
"Good morning class! Today, we will explore the fascinating world of mixtures and solutions. Can anyone tell me what they think a mixture is?
[Pause for responses.]
"Great thoughts! A mixture is a combination of two or more substances where each keeps its own properties. On the other hand, a solution is a special type of mixture where one substance is dissolved in another. For example, when we mix salt into water, we get a solution. What about some everyday examples of mixtures?
[Encourage students to share their examples.]
"Excellent! Some common mixtures we encounter are things like salad, air, and mud. Now that we have a basic understanding, let’s dive a little deeper."
"Let's discuss this further! I want you all to think about the mixtures and solutions you see in your everyday life. Can anyone give me specific examples?
[Encourage students to raise their hands and respond, noting their examples on the whiteboard.]
"Interesting examples! Did anyone mention a drink, like lemonade? That's a solution, while something like cereal in milk is a mixture. By examining these, we start to see how mixtures and solutions are all around us.
"But why do we categorize them differently? Let's think about that for a moment."
"Now, I’m going to hand out some printable cards to each of you. Please take one and fill in two columns: one for mixtures and one for solutions. Think about the examples we discussed, and also include any others you know.
[Distribute the cards.]
"You’ll have about seven minutes to complete this task. Remember to think critically about what defines a mixture versus a solution!"
"Okay, time is up! Now, I want you to pair up with your neighbor and share what you wrote on your cards. Discuss the differences between your examples of mixtures and solutions.
[Circulate the room to listen in on discussions.]
"Feel free to ask each other questions and clarify any doubts!"
"Let’s wrap up the card activity! I will now randomly collect a few of your cards to check for understanding. Don’t worry, this isn't a test—it's just to help me see how well we're grasping these concepts.
[Choose a few cards to collect and review while students observe.]
"Great job sharing your examples; I can see many of you are getting the hang of it!"
"To summarize what we learned today: a mixture retains the properties of its components, while a solution is a mixture where one substance dissolves in another. We’ve seen examples in our everyday lives and had some great discussions.
"Before we end, does anyone have any final questions or thoughts?
[Encourage a brief Q&A session.]
"Fantastic work today, everyone! For your homework, I want you to find one example of a mixture and one example of a solution at home. Write a short paragraph explaining each one and submit it digitally. I look forward to reading your findings! Have a wonderful day!"
