| 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} |

Science
Acids and Bases
Year 7
30 minutes
20 students
The lesson aligns with the Australian National Curriculum for Science, particularly focusing on:
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction to Acids and Bases | 5 min | Briefly introduce the concepts of acids and bases. Discuss their importance and uses. |
| 2 | Group Activity: Card Filling | 10 min | Distribute printable cards to each student. Explain what they need to fill in on the cards regarding acids and bases. |
| 3 | Demonstration (Optional) | 5 min | Show examples of common acids and bases, either in class or via video. Discuss reactions if applicable. |
| 4 | Random Check/Collect Cards | 5 min | Collect or randomly check the cards students filled in to assess understanding. Ensure to provide feedback individually. |
| 5 | Recap & Conclusion | 5 min | Summarize key points discussed in the lesson. Answer any lingering questions from students. |
Students will be assigned a short written reflection on what they learned about acids and bases. The reflections will be submitted in the next class without individual presentations.
“Good morning, everyone! Today, we’re going to dive into an exciting topic in science—acids and bases! First, I want you to think about what you already know. Can anyone tell me what an acid is? Yes, great answers! Acids are substances that can donate protons, and they often taste sour. Now, how about bases? That’s right; bases can accept protons and usually taste bitter.
Acids and bases are everywhere in our daily lives. For example, vinegar is an acid that we use in cooking, and baking soda is a base that helps our cakes rise. Understanding these concepts is not just important for science class; it helps us understand chemistry in the world around us. By the end of this lesson, you’ll know more about these substances, their properties, and their uses!”
“Now, let’s get into some hands-on learning! I’m going to hand out printable cards to each of you. The cards have two sections: one for acids and one for bases. Your task is to fill in the cards with examples of each substance that we regularly encounter in our lives and also write down where we typically use them. You’ve got 10 minutes to work on this, and remember, you can consult your notes if you need to!
As you work on these cards, I want you to think critically—why do we use these acids and bases in particular situations? Ready, set, go!”
[Teacher circulates the room to assist students as needed and encourage discussion.]
“Alright class, who’s excited for some demonstrations? Just as a side note, if you’re ever curious about what happens when an acid meets a base, I have some samples right here.
[If applicable, show vinegar and baking soda or play a short video demonstrating a reaction. Ensure safety protocols are followed.]
“Here I have vinegar, which is an acid. And here is baking soda, a base. Watch closely as I mix them. What do you observe? That’s right—the mixture fizzes! This is a neutralization reaction. Acids and bases often react to form water and salt, which can be quite fun to observe as you see here. Do any of you have similar experiences you’ve seen or heard about?”
“Now that we’ve explored acids and bases, I’d like to check in on the cards you filled out. I will randomly collect some of your cards, so make sure you’ve completed them.
[Teacher collects cards or might ask students to raise their cards up for quick checks.]
“I’ll provide some feedback based on what I see. Great work, everyone! It’s important that you understand the properties and examples of acids and bases because they are fundamental to so many reactions in nature and science. Let’s take a moment to glance over the ideas you’ve put down.”
“Alright, everyone! To wrap up our lesson today, let’s summarize what we learned. Can someone remind me what the properties of acids are? Yes, they tend to taste sour and have a pH less than 7! And how about bases? Correct—they taste bitter and have a pH greater than 7!
Remember, understanding these concepts helps us make sense of many reactions that occur both in the lab and in everyday life.
Finally, do you have any questions about what we covered today?
For your homework, I’d like you to write a short reflection on what you learned about acids and bases today. Be sure to include an example of each and where you might encounter them in real life. You’ll submit these in our next class.
Thank you for your engagement today! I’m looking forward to reading your reflections!”
