Key Ideas Purpose of nitrogen and phosphorus Why extra nitrogen and phosphorus is added to soil Different types of plants need different amounts of nitrogen and phosphorus How nitrogen and phosphorus get into water systems Eutrophication, hypoxia and dead zones

Create a hypothesis. Which soil do you predict will have more nitrogen and/or phosphorus and why?

Enriching our Seas to Death Readers – share out on what your article was about Audience – take notes. Key points to know: 1.What is eutrophication? 2.How is it caused? 3.Which nutrient cycles were impacted? 4.What are dead zones 5.What are the actions of humans that have caused this? 6.What are solutions

Exit Card 1.What is eutrophication and what does it cause? 2.Name two problems caused by algae growth (algae is a producer…. That is a good thing, right?) 3.Does nitrogen & phosphorus ( and not carbon or sulfur) cause hypoxia?
