activities that focus on the scientific method, lab reporting, and data collection and management.
As you view the video, you will be prompted to stop and answer the Exercise 1 questions on the
Week One Lab Reporting Form
. Make sure to complete all of the following items before
submission:
•
•
Read through the introductory material.

Week 1 – Assignment
Environmental Footprint
The purpose of this assignment is to provide you with an opportunity to learn more about how
connected you are to the ecosystems and biosphere that you inhabit. You will learn how your
everyday choices impact our environment. Most importantly, you will learn about the benefits of
joining the increasing number of people who are making choices that reduce their environmental
impact.
First, calculate your ecological footprint (If you are having difficulty getting any of the proper
information from the calculator, you may need to try a different web browser. For instance, if
you are using Google Chrome, you may need to use Internet Explorer, Safari, Mozilla, etc. If you
are using one of these and are experiencing difficulties, you may need to try Google Chrome,
etc.).
•
•
Use the Footprint Calculator (Links to an external site.)Links to an external site. to
measure your ecological footprint and learn “how many Earths” it takes to support
your lifestyle. Be sure to choose the “detailed response” option for each question.
Answer each question in the quiz honestly and record your answers and results in the
Environmental Footprint Reporting form
.
Second, calculate your household carbon emissions.
•
•
Use the Household Carbon Footprint Calculator (Links to an external site.)Links to an
external site. to measure your carbon emissions and determine your environmental
impact and the benefits of solutions.
o Section 1: Estimate your current total household emissions (from home energy
use, vehicle use, waste).
o Section 2: Explore actions you can take to reduce your greenhouse gas
emissions, energy use, and waste disposal costs.
o Section 3: See how much you can save (in dollars and emissions) by taking the
actions you chose in Section 2.
Answer each question in the quiz honestly and record your answers and results in the
Environmental Footprint Reporting Form. Complete Tables A and B as well as
assignment questions 1 through 4 in complete sentences on the Environmental
Footprint Reporting Form.
Once you have completed the required sections within the Environmental Footprint Reporting
Form submit the document via Waypoint. The document does not need to include a title page or
other APA formatting; however, if you utilize any outside sources in your answers, you must
reference these sources in proper APA format as outlined in the Ashford Writing Center.
In this class, you have three tutoring services available: Paper Review, Live Chat, and Tutor Email. Click on the Writing Center (AWC) tab in the left-navigation menu, in your online course,
to learn more about these tutoring options and how to get help with your writing.
Lab 1 – Introduction to Science
Exercise 1: The Scientific Method
In this exercise, you will answer the questions based on what you have seen in the videos
throughout the lab. Be sure to pay careful attention to the videos – you will not only need them to
complete this exercise successfully, but also to have a firm understanding of the scientific method
for future labs.
QUESTIONS
1. Make an observation – Write down any observations you have made regarding the effect
of pollution on the environment.
Answer =
2. Do background research – Utilizing the scholarly source (provided here), describe how
pollution might affect yeast.
Answer =
3. Construct a hypothesis – Based on your research from question 2, develop an if-then
hypothesis relating to the effect of pollution on yeast respiration.
Answer =
4. Test with an experiment – Identify the dependent variable, independent variable, and the
controlled variables for the experiment.
Answer =

5. Analyze results – Record your observations of the three test tubes before incubation and
compare them to the observations provided in the video.
Answer =
Test Tube
Yeast with No Pollutant
Yeast with Salt Water
Yeast with Detergent
Initial Appearance
6. Analyze results – Record your observations of the three test tubes after incubation.
Answer =
Test Tube
Yeast with No Pollutant
Yeast with Salt Water
Yeast with Detergent
Final Appearance
7. Analyze results – The table below shows sample data regarding the amount of carbon
dioxide produced by each tube. Determine what type of graph would be the most
appropriate for displaying the data and explain why you chose that graph. Then, make a
graph. Use Microsoft Excel or a free graphing program (for example,
https://nces.ed.gov/nceskids/createagraph/) to create the graph. Submit this with your
post-lab questions.
Sample
Yeast with No Pollutant
Yeast with Salt Water
Yeast with Detergent
Amount CO2 Produced (mL) After 1 Hour
7 mL
0.5 mL
0 mL
Answer =
8. Draw conclusions – Interpret the data from the graph in Question 7. What conclusions
can you make based on this graph?
Answer =

9. Draw conclusions – Based on your observations and your graph, would you reject or
accept the hypothesis you made in Question 3? Why?
Answer =
10. Draw conclusions – Imagine you are an environmental scientist employed by a city. Some
residents have expressed concerns regarding how salt is applied to roadways in the winter
because of the harm it may cause aquatic life in area streams. Propose an experiment
using yeast to determine if salt pollution runoff is a potential concern in your community.
