Our Classroom Report

"What did we learn, and what should we do about it?"

Scientists don't just collect data - they share what they learned with others! Today you'll create an Air Quality Report for our classroom.

Your report should answer:

• What did we measure?
• What did we find?
• What does it mean?
• What should we do about it?

Classroom Air Quality Report

Room: _______________ Date: _______________

Scientists: _______________

---

1. What We Measured

We used a CO2 sensor to measure carbon dioxide levels in our classroom throughout the day.

2. Our Data

Lowest CO2: _______ ppm at _______ (time)

Highest CO2: _______ ppm at _______ (time)

Average CO2: _______ ppm

[Include your graph here!]

3. Air Quality Rating

Based on our data, our classroom air quality is:

• [ ] Excellent (mostly under 600 ppm)
• [ ] Good (mostly 600-800 ppm)
• [ ] Fair (mostly 800-1000 ppm)
• [ ] Needs Improvement (often over 1000 ppm)

4. What We Noticed

Patterns we observed: _________________________________

CO2 went UP when: _________________________________

CO2 went DOWN when: _________________________________

5. Our Recommendations

To improve our classroom air quality, we recommend:

1. _________________________________
2. _________________________________
3. _________________________________

Group Work

Work in small groups to complete the Air Quality Report. Each group member can contribute:

• Data Analyst: Calculates averages and fills in numbers
• Graph Maker: Creates or cleans up the graph
• Writer: Writes the "What We Noticed" section
• Recommendation Expert: Comes up with solutions

Each group will share their report with the class. When presenting:

1. Show your graph and explain what it shows
2. Share your air quality rating
3. Explain the most important pattern you noticed
4. Present your top recommendation

Listeners: Think about questions you have or whether you agree with the recommendations!

What Happens Next?

Your report isn't just a school assignment - it's real science! Consider:

• Share with the principal: They might be interested in your findings!
• Post in the classroom: Remind everyone about ventilation
• Keep monitoring: Check CO2 regularly to see if changes help
• Tell other classes: They might want to do their own investigation!

In this unit, you learned to:

1. Use sensors - Tools that measure things we can't see
2. Collect data - Measurements at regular intervals with notes
3. Make graphs - Visual ways to see patterns in data
4. Communicate findings - Reports that share what you learned
5. Make recommendations - Use evidence to suggest improvements

You are now real air quality scientists!
