Week 5: Environmental Monitoring & Solutions
Grade 7 Science | Rosche | Kairos Academies
Week 5: YOU Complete All Steps Independently
By Week 5, you've built your problem-solving skills through progressive practice. Now it's your turn to integrate concepts across all weeks!
YOUR TURN - Complete All Steps:
Step 1: Which satellite data would you use for each environmental issue? (NDVI for what? Sea surface temp for what? Chlorophyll concentration for what?)
Step 2: Where would you place ground sensors to validate satellite data and catch local problems?
Step 3: How do the 4 environmental issues CONNECT? If nitrogen loading increases, what cascade effects might occur across the other 3 systems?
Step 4: What threshold values would trigger an alert for each issue?
Step 5: What ACTION would you recommend when each alert triggers?
Fading Support Complete: Week 1 showed all 5 steps. Week 2 showed 3 steps. Week 3 showed 2 steps. Week 4 showed 1 step. This week, YOU do it all! This is how scientists work - integrating multiple data sources to understand complex systems.

Technology Analysis βΌ
20 Points | ~18 Minutes
Compare monitoring technologies and understand multi-scale
approaches.
Your Mission: Compare Monitoring Technologies
Compare Monitoring Technologies:
| Technology | Advantages | Limitations | Best For |
|---|---|---|---|
| Satellites | Global coverage, historical data | Low resolution, clouds block view | Large-scale trends |
| Drones | High resolution, flexible timing | Limited range, weather dependent | Local detail |
| Ground sensors | Continuous, precise measurements | Small area, expensive to maintain | Specific locations |
| Citizen science | Large workforce, low cost | Variable quality, training needed | Widespread data |
Multi-Scale Monitoring (Best Practice):
The best monitoring systems combine multiple technologies: satellites for the big picture, drones for medium detail, ground sensors for precision, and citizen science for coverage. This is called "multi-scale monitoring."

βΌ Station 3 β Design a
Monitoring System βΌ
25 Points | ~20 Minutes
Engineer a multi-scale monitoring system to detect environmental
problems early.
Engineering Challenge: Design a Monitoring System
Design Challenge:
A local watershed has problems with fertilizer runoff (Week 4) leading to algae blooms (Week 2). Design a monitoring system that can detect problems BEFORE dead zones form.
Your monitoring system should include:
- What parameters will you measure? (nutrients, oxygen, temperature, etc.)
- What technologies will you use? (Choose at least 2 from Station 2)
- Where will you place sensors/monitoring points?
- How often will you collect data?
- What will trigger an alert? (threshold values)
- What action will you recommend when alerts trigger?
COMPLETING THIS AT HOME?
Consider these real-world constraints as you design:
- Budget: You can't have sensors everywhere - where do you prioritize?
- Response time: How quickly do you need to know about problems?
- Action: What can actually be DONE when you detect a problem?
βΌ Need extra support? Click for design hints βΌ
Design Strategy:
- Think about the PATHWAY: Where do nutrients enter? Where do they accumulate?
- Consider EARLY DETECTION: What's the first sign of a problem?
- Plan for ACTION: What can people actually do with your data?
Sentence Starters:
- "My monitoring system will measure _____ because..."
- "I chose this combination of technologies because..."

Station 3 (25 pts) βΌ
Step-by-step approach to maximize your engineering design
points.
This station tests your engineering design skills. Here's how to maximize your points:
Step-by-Step Approach:
- Identify WHERE to intervene: At the SOURCE (farms), along the PATHWAY (rivers), or at the ENDPOINT (dead zone)?
- Choose COMPLEMENTARY technologies: Satellites for big picture + ground sensors for precision
- Set REALISTIC thresholds: What levels indicate a problem? (Use Week 2 data!)
- Plan the RESPONSE: Who gets alerted? What action can they actually take?
- Connect to prior weeks: How would this system detect the problems from W1-W4?
Pro tip: The best answers explain WHY each component of your system matters and connect back to the environmental issues from Weeks 1-4. Remember: monitoring identifies problems, but ACTION is required to solve them!

Optional deep dives into systems thinking, scientist profiles, and
environmental justice.
Systems Thinking Reflection
Satellites can see things we can't. Use these questions to think about how monitoring connects to solutions.
Cause β Effect Chain
Satellite detects β NDVI β Scientists investigate β Discover deforestation β Alert local authorities
Your turn: How could early detection prevent problems from getting worse?
Trade-Off Thinking
Satellites cover huge areas but can't see underwater. Buoys measure precisely but only one spot...
Your turn: Why do scientists use BOTH satellites and buoys to monitor ocean health?
Feedback Loop

Cycle 4 Synthesis: You've learned about ocean acidification (W1), dead zones (W2), carbon cycle (W3), nitrogen cycle (W4), and monitoring (W5). How does monitoring help us solve ALL of these problems?
Scientist Spotlight: Dr. Efi Foufoula-Georgiou
Dr. Efi Foufoula-Georgiou is a pioneering environmental engineer who uses satellite data and mathematical models to track how rivers, deltas, and coastal ecosystems respond to human impacts - exactly the monitoring challenges you're studying this week! Born in Greece and now working at UC Irvine, she develops algorithms that turn satellite images into actionable environmental data, helping communities predict floods, track sediment pollution, and monitor wetland health.
Her breakthrough work focuses on the Mississippi River Delta - the same system that carries nitrogen pollution to the Gulf of Mexico dead zone you learned about in Weeks 2 and 4. Dr. Foufoula-Georgiou's satellite monitoring systems can detect when nutrient levels spike in river water before they reach the Gulf, giving communities early warning to prepare for algae blooms.
As a woman in engineering and an immigrant to the U.S., Dr. Foufoula-Georgiou faced skepticism early in her career. She's now a member of the National Academy of Engineering. Her message to students: "Environmental monitoring isn't just about technology - it's about justice. The communities most affected by environmental change often have the least access to the data that could protect them. Your job as future scientists is to make monitoring tools accessible to everyone."
Environmental Justice: Who Gets Access to Monitoring Data?
Wealthy communities can afford private air quality monitors, water testing, and access to premium environmental data services. Poor communities - disproportionately Black, Latino, and low-income - often lack even basic environmental monitoring. In St. Louis' North City neighborhoods near chemical plants and industrial facilities, residents for decades complained about cancer clusters and respiratory illness, but lacked the data to prove industrial pollution was the cause.
This is environmental monitoring injustice: polluting industries actively oppose monitoring in fence-line communities because data would prove they're violating regulations. Meanwhile, industry installs extensive monitoring at their own facilities to optimize operations.
Community-based organizations like Missouri Coalition for the Environment and Metropolitan Congregations United in St. Louis fight for "community science" - putting monitoring tools directly in residents' hands. Understanding environmental monitoring means asking: Who controls the data? Who benefits from knowing - or not knowing - pollution levels? And how do we democratize access to environmental information?
Community River Monitoring Project (Optional Extension)
Design a real-world local action project monitoring the Mississippi/Missouri Rivers:
Your Task: Design a student-led monthly water quality monitoring project for a local St. Louis river site. Include: (1) Which parameters reflect C4 cycles (pH for acidification, nutrients for eutrophication, vegetation for carbon)? (2) How will your team collect data? (3) What action could your school take based on findings?
