Grade 7 Science | Rosche | Kairos Academies
Cycle 3 Cumulative Assessment | 100 Points Total | ~75 Minutes
⚠️ ASSESSMENT WEEK - Important Information
- This is your cumulative assessment for Cycle 3 Climate Change unit.
- You may NOT go back once you submit each part.
- Complete all 3 parts in order: Synthesis → Assessment → Misconception Check
- Take breaks between parts - your brain works better with rest!
- Ask Mr. Rosche if you need clarification on any question.
📝 What You Need to Know (Review Guide)
| Week | Key Concepts |
|---|---|
|
Week 1 Greenhouse Effect |
|
|
Week 2 Feedback Loops |
|
|
Cycle 2 Spiral |
|
🎯 Practice These Vocabulary Terms
⚠️ Common Mistakes to Avoid
| ❌ WRONG | ✅ CORRECT |
|---|---|
| "Breaking bonds releases energy" | Breaking bonds REQUIRES energy; forming bonds releases energy |
| "Mass disappears in reactions" | Mass is conserved; atoms rearrange but are never destroyed |
| "Positive feedback is good" | Positive means AMPLIFYING (same direction), not beneficial |
🔗 Part 1: Synthesis Review
20 Points | ~15 Minutes | Connects Week 1 + Week 2
What you'll do:
- Create a diagram connecting greenhouse effect, feedback loops, and human emissions
- Identify the primary driver of climate change
- Explain how the complete system works together
- Connect to Cycle 2 conservation concepts
📝 COMPLETE PART 1
⏸️ Take a 5-minute break before Part 2!
📝 Part 2: Cumulative Assessment
60 Points | ~40 Minutes | All Learning Targets
Sections:
- Section A: Greenhouse Effect (15 pts) - Molecular mechanisms
- Section B: Carbon Cycle & Conservation (15 pts) - Calculations + concepts
- Section C: Albedo & Feedback Loops (15 pts) - System thinking
- Section D: Integration (15 pts) - Connecting everything
⚠️ You cannot go back once you submit. Read carefully!
📝 COMPLETE PART 2
⏸️ Take a 5-minute break before Part 3!
🎯 Part 3: Misconception Check
20 Points | ~20 Minutes | Final Chance!
What this tests:
- Bond Energy: Breaking bonds requires energy (most common mistake!)
- Conservation of Mass: Atoms are never created or destroyed
- These questions are designed to catch common errors - think carefully!
📝 COMPLETE PART 3
🎉 Cycle 3 Complete!
Congratulations on finishing the Climate Change unit!
Key Takeaways:
- CO2 absorbs IR → molecules vibrate → heat trapped
- Carbon is conserved through all Earth systems
- Positive feedback loops accelerate climate change
- Multiple feedbacks interact and amplify each other
