Assignment: SCI103 Unit 2 Individual Project (Lab Report)
Measuring pH Levels
Instructions: Enter the Virtual Lab, and conduct the lab tests. Please record your answers on this Lab Report form. When your Lab Report is complete, submit it to the Submissions area of the Virtual Classroom.
The pH Scale: https://youtu.be/Xkrgw2CFwRs
Part I – Lab Tests: Answer the following questions while in the virtual lab.
Section 1: You will test 4 known solutions for pH levels using a standard wide-range indicator. Based on the results obtained in the virtual lab, fill in the following table:
Solution Number pH from Lab Acid, Base, or Neutral? Solution Name (What was in the test tube?)
Solution 1
Solution 2
Solution 3
Solution 4
Section 2: Now that you understand how to read pH measurements, follow the virtual lab to gather pH samples from 3 different lakes. Test these in the virtual lab, and answer the following questions:
What was the pH level measured at Lake 1?
What was the pH level measured at Lake 2?
What was the pH level measured at Lake 3?
Which two lakes have the highest levels of acidity in their water?
Part II – Your Examples: Use the templates below to guide your answers.
Look for at least 3 acids and at least 3 bases around your home. Remember that acids have a pH level lower than 7, pH 7 is neutral, and bases have a pH level higher than 7.
Three examples of acids that I found in my home are:
__________
__________
__________
Describe each of the three acids using complete sentences. Some suggestions…what do they contain, what they are used for and why, what are their properties, what is their pH?

3.
Describe the common attributes of acids:
Three examples of bases that I found in my home are:
__________
__________
__________
Describe each of the three bases using complete sentences. Some suggestions…what do they contain, what they are used for and why, what are their properties, what is their pH?
Describe the common attributes of bases:
Part III – Short Answers: Answer the following questions in short-answer format (3–5 detailed sentences each).
Look at your data for the three lakes in the virtual lab. Acid rain is impacting two of these three lakes. Answer the questions below to explain how the location of each lake relates to its pH level.
What is acid rain?
Which two lakes from the virtual lab are receiving acid rain?
Discuss how the location of each lake (Lake 1, Lake 2, and Lake 3) relates to its pH level. Include some of the impacts of acid rain. Use data from Part 1, including what you observed on the signs for each lake, to justify your points.
Imagine that a lake receives acid rain for an extended period of time. The original pH of the lake was 6, but it has now dropped to pH 3. How many times more acidic has this lake become? Watch this resource video for help: https://www.youtube.com/watch?v=Nf8cuvl62Vc
What negative impacts can this amount of acidification have on the environment?

Assignment Details
Welcome back, Scientists! Chemistry is all around us. This week, you will explore the impact of pH by conducting simulated lab and field tests.
Start this week with the Unit 2 Learning Path in intellipath® (located in the Assignments list). Here, you will be taught the following fundamental aspects of chemistry that you will need to complete this week’s lab activity, the Unit 2 Individual Project:
pH
Acids and bases
Acid rain
Continue on to the Unit 2 Individual Project (instructions below):
Don’t forget to read! You will learn more about the basics of chemistry, such as the following:
Types of elements
Chemical bonds
Chemical reactions
Don’t be a stranger! Your instructor loves hearing from you. Let them know how you are doing this week, and touch base with any questions you might have. You’re doing great!
Lab 2: Measuring pH Levels
For this assignment, you will use the Unit 2 Measuring pH Levels Learning Module to complete the Unit 2 Lab Report worksheet. You will be conducting simulated lab and field tests to determine pH levels of collected samples.
If you haven’t already, download the Lab Report worksheet.
Then, view the Unit 2 Lab: Measuring pH Levels to complete the virtual lab and Lab Report worksheet.
Submit your completed assignment in one of the following ways:
Upload your completed Lab Report.
Upload an image with your completed Lab Report.
Type in your responses to the Lab Report in the IP submission text box.
View the Individual Project Demo for guidance on how to submit your Lab Report as an Individual Project via the Virtual Classroom or the CTU Mobile app.
SCI 103 Unit 2 Individual Project -Specific Grading Criteria
SCI103 Unit 2 Individual Project Grading CriteriaMax PointsThe pH values, solutions, and acid/base identifications are accurate.10The three lake pH’s are accurate, and the two most acidic lakes are identified correctly.10Three to five sentences are used to describe acids found in the home and their common attributes.10Three to five sentences are used to describe bases found in the home and their common attributes.10Three to five sentences are used to explain what acid rain is. Data from Part 1 is used to discuss how each lake’s location causes varying impacts of acid rain.15The acidic concentration change from pH 6 to pH 3 is given correctly, and environmental impacts of this change are accurately presented in 3–5 sentences.15Uses proper spelling, punctuation, and grammar to write clearly and effectively.5Total points earned:75
