Assignment:

You are a wildlife biologist and you are studying DDT levels in Great Blue Herons (a large bird that typically eats fish). We actually get one that hangs out at the pond on the MC campus.

You are taking blood samples from the birds you capture and measuring DDT levels. You captured one bird at each location. Below you see your data.

Location	Level of DDT in Blood (mg/ml)
MC Pond	67
Rock Creek Park	107
Seneca Creek State Park	34
Great Falls	49
Black Hill Regional Park	21

1. Using Excel, graph the data using the appropriate type of graph. Include title and label your axes.

2. Why might certain parks have birds with higher DDT levels?

3. Would great blue herons typically have higher or lower DDT levels than smallmouth bass fish? Why do you think this? What do you know about DDT that supports your answer?
