Reflection Assignment for Week 7


Students will perform an experiment link to a local environmental issue; instructor must approve the topic. Your proposed experiment must have hands on lab work for at least 2 hours.

Learning Objective(s) Addressed by This Activity

  • Describe a local environmental issue.
  • Evaluate the role humans have played and if this issues cause health problems.
  • Understand how the public plays a role in fixing the issue.


Consider the environment in your local area ad pick an environmental topic or issue for which you would like to complete an experiment on (HINT-- it helps to have the same topic for both SC370 & SC370L, you can use the same recourse and general background information). Select an environmental topic that has impact in your area and is one of the topics that we have covered in the past 7 weeks. You must propose and environmental lab and carry out the experiment.

Final Local Experiment Paper Guidelines

Final Local Experiment ***Due Day 7 week7*** More than four decades after the first Earth Day, there are still many environmental concern for communities around the world to address. However progress is being made and it could be argued that awareness about environmental issues is at an all-time high. The assignment is based on hands on experiment that you must select on your own.

Laboratory report on Water Quality

This study on laboratory report aims to investigate the environment issues impacts on the
water quality. The primary focus of the focuses on showing the correlation between human
activities on the environment which pollutes water meant for human consumption.


examination of the water quality uses biological analysis using the coliform test to detect the
presence of Escherichia coli in water supplied in my area for human use. The test confirmed the
presence of E.coli or commonly known as gram-negative bacilli is non- spore which ferments in
lactose to emit H2S gas. The medium which contains ferrous ammonium citrate react with gas
then turn into black color with 2 two days. From the positive results obtained laboratory report
analysis, it is clear that contamination arises from Unhygienic social practices, Poor sanitary
conditions in the environment it is the sources of water and poorly discharged wastes sewage and
domestic wastes.

However, the study further discussed the human contribution to water

pollution, strategies for educating the community on benefits of protecting water from
contamination. Additionally, the study explains how the community can directly participate in
maintaining water quality and safety for human consumption.



Water Quality is vital for human, animal and aquatic lives. Scientists describe water
Quality regarding the composition of chemical, biological and physical characteristics (Angers,
2017). Additionally, some factors such as bacteria, salinity, pesticide and herbicide and heavy
metals contaminants considered when determining the quality of water. Water quality is a
significant environmental issue which can create health risks for the ecosystems (Odume,2017).
Water resources have ecological and social and economic impact to the communities relying on
its supply. The environment becomes polluted due to both human activity and natural processes
such as soil erosion result in water resource losing its values. The Environmental experts
describe water quality as a subject which is more connected to the environmental activities. For
instance, if the environment is not conserved and protected from pollution, human and animal
life will face the danger of consuming contaminated water. However, water quality may not
only vital to public health since used for domestic purposes. Additionally, water quality problem
dictates the way the society use water for activities like industrial processes, production of edible
fish, irrigation of crops and recreation activities such as swimmi...
