Discuss the BTN Ozone Improvement story as a class. What questions were raised in the discussion (what are the gaps in their knowledge)? The following KWLH organiser provides students with a framework to explore their knowledge on this topic and consider what they would like to know and learn. Students will develop their own question/s for inquiry.

What do I know? What do I want to know? What have I learnt? How will I find out?

©ABC 2017 Students will investigate in more depth some questions they have about the ozone layer.

Define: What do I want to know?

Key questions to research Students can choose one or more of the following questions or come up with their own:

 What is ozone and why is it important?  What are the consequences of ozone depletion? How do humans contribute to the problem?  Where is the hole in the ozone layer? What is the current status of the hole?  What is the Montreal Protocol and what has it achieved?  How is ozone measured?  How might the world look without the ozone layer to protect it?

Locate: Where do I find the information? What resources will help answer my questions? (Internet, people, resource centre, organisations, print). Discuss with students what a reliable source is.

Select: What information is important for the investigation? Students may need support to sort through and select relevant information.

Organise: How do I make sense of the information? Students can organise their research by creating main headings from their questions. Write each heading on a separate piece of paper. Record the information found for each question.

Present: How do we let others know about this information? Students decide on the best way to present the information. Possibilities could include:  A `Did You Know’ Fact sheet  Create an infographic using Canva  Prezi presentation  Oral presentation  Make a website using Wix  Create an interactive poster using Glogster

Evaluate: What have we learnt? Students reflect on what they have learnt about the ozone layer and respond to the following.  What I learned...  What I found surprising...

The Ozone Layer animation explains what ozone is and how the ozone layer became depleted. Students can use the information in the animation to help them with their research.

1. What did scientists predict would happen by 2065? 2. Describe the impact it would have on people’s lives. 3. What is ozone? 4. What does ozone absorb? 5. What are the consequences of ozone depletion? 6. Name the substance that was causing the hole in the ozone layer. 7. What happened as a result of the Montreal Protocol?

Create a Quiz Use Kahoot! to test students’ knowledge about the ozone layer. Quizzes can be created to recap learning or test personal knowledge. There is also the option to connect with classrooms around the world and play kahoot in real time.
