SCI 207 DEPENDENCE OF MAN ON ENVIRONMENT
SCI 207 NEW Week 1 Assignment Environmental Footprint
1. What are the 3 everyday products and practices that contribute most to your environmental footprint?
Mobility, Goods and services
2. What impacts might result if everyone in the world had the same lifestyle as you? For example, what might the impacts be on:
A. Earth’s climate? We would have a really polluted air more than what it is now
B. The health of ecosystems and biodiversity? It would not have much of a health
C. Humanity’s natural resource base and thus economic security? NO security or natural resource, our natural resources will be contaminated.
SCI 207 NEW Week 1 Lab 1 Introduction to Science
1. What patterns do you observe based on the information in Table 4?
The fewer amounts of fish, the more oxygen there is in the water. They oxygen is measured in 2’s and the less fish there is the more oxygen there is.
1. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?
The more fish there is, the less amount of oxygen there is in the water. According to author’s Mckinsey& Chapman, “for fishes, dissolved oxygen is an abiotic factor that can limit habitat quality and affect survival, growth, and reproduction” (Mckinsey, D. & Chapman, L. 1998, pg. 211, para. 1).
1. What would your experimental approach be to test this hypothesis?
I would add fish to the water and test the oxygen, and then remove fish and test the oxygen with each (ppm) in counts of 2 (ppm). Also, I would use the same spot, and the same time of day.
1. What would be the independent and dependent variables?
