In this project, you will demonstrate your mastery of the following course outcomes:
Determine fundamental approaches to scientific research in addressing questions related to the natural world
Develop questions about fundamental aspects of the natural world that inform personal assumptions, beliefs, and values using empirical evidence
Investigate questions about fundamental aspects of the natural world that inform personal assumptions, beliefs, and values using empirical evidence
Articulate the value of the natural sciences for their impact on contemporary issues
Overview
This course will introduce you to fundamental ideas in the natural sciences and how scientists study phenomena in the natural world. Having a well-rounded understanding of scientific research is much more than just an academic pursuit. We encounter natural science every day. Consider news headlines about vaccine development, debate about climate change, privatizing space exploration, how bees affect our environment, and whether intestinal health impacts mental health. Think about the conversations you’ve had with friends and family about weather, gardening, cancer, or black holes. These are all natural science topics!
Being scientifically literate helps you to better understand the world, solve problems, and make informed judgments. It also allows you to evaluate the credibility of claims you hear in the news or from members of your community. A society that understands how science works thinks critically about information, is empowered to make better decisions, and is less likely to be misled by those who distort evidence to promote their own agenda.
In this project, you will use a recent news article to identify a natural science topic that you are curious about. You will explore how research is conducted about the topic, scientific developments that have affected it, and its societal significance. This will provide you with a deeper understanding of scientific research and the fundamental aspects of the natural world.

Task 1 Comparing and Scaling Planet Sizes Scale drawings and models are used to

Task 1
Comparing and Scaling Planet Sizes
Scale drawings and models are used to represent objects that are too large or too small to be drawn or built at actual size, such as a planet. While the size of a scale model is different than the actual object, the model and the object should be proportional. Scaling uses a ratio called the scale factor, which compares the measurements of the drawing or model to the measurements of the real object. Consult the Math Review for more help with scale factors.
In this task, you will scale the diameter of each planet in our solar system and start building a model of the solar system.
Estimated time to complete: 1 hour
You will need these materials:
4 pieces of paper or poster board, 8.5” x 11”
scissors
pencil or pen
ruler
compass used to draw circles (optional)
calculator (optional)
Part A
Question
The circle represents Earth. Based on the size of Earth, predict the relative sizes of Earth’s moon, Jupiter, and Mercury by drawing them next to Earth. Remember that Jupiter is the largest planet in our solar system, and Mercury is the smallest. Draw your prediction in the space provided and label your circles.

Width:
Part B
The table contains the planets in our solar system in order of their average distance from the Sun and their corresponding diameters. The first step in creating a model of the solar system is to scale these large diameters into smaller, more manageable numbers. Eventually, we’ll represent these numbers using circles drawn on paper.
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Diameter (km)
4879
12,104
12,756
6792
142,984
120,536
51,118
49,528
Scaled Diameter (cm)
3.5
1.9
The ratio between Earth’s actual diameter and its scaled diameter can be used to find the scaled diameter of the other planets. Earth’s diameter of 12,756 kilometers is scaled to 3.5 centimeters as shown in the table. Now let’s find the scaled diameter of Mars as an example. Using the calculations shown, Mars’s diameter of 6,792 would be scaled to 1.9 centimeters.
d × 12,756 = 6,792 × 3.5
d = 1.9 cm
Use this same process to complete the table with the scaled diameters of the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.
Part C
Draw each planet on paper using the scaled diameter found in part B. Use a ruler and, if possible, a compass to draw your planets as shown in the images. Notice that in both of these images the radius (half the diameter) is used to create a circle.
If you need help with circles, visit the Properties of Circles section of the Math Review. For assistance with taking measurements, visit Lab Instruments and Measurements.
Be sure to label each planet with its name, and then cut them out. Place the planets in order based on their average distance from the Sun, shown in the table in part B. Now, compare the sizes of the planets. What relationship do you observe between a planet’s size and its proximity to the Sun? If possible, snap a photograph of your model. Click the Insert Image button to add your image file (.jpg or other) in the answer space.
Part D
The Sun has a diameter of approximately 1,391,400 kilometers. How big would the Sun be in your scaled-down model of the solar system? Explain how you scaled the Sun’s diameter to fit into your model, and describe how its size compares to the planets.
Save your paper planets. You’ll use them in the next task.
Task 2
Comparing and Scaling Planet Distances
Now that we have the size of the planets scaled, we need to know how far apart to place them in order to complete our model. In this task, you will scale the distances between the planets and the Sun and complete your model of the solar system. Once again, consult the Math Review as needed for help with scale factors and proportions.
Estimated time to complete: 1 hour
You will need these materials:
toilet paper
pencil or pen
an object and location to represent the Sun
calculator (optional)
large working space, such as a hallway (Make a partial model if your space is smaller.)
Part A
Arrange the cut-out planets you made in Task 1 in order according to their proximity from the Sun, as shown below. As an alternative, you may cut out the scaled planets.
Sun
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
At a large desk or on the floor, choose a position to represent the Sun, and place Mercury a few inches from it. Predict the relative distances between each of the other planets, and space them out accordingly. Do you think the average distances between each of the planets stays relatively consistent or varies greatly? What leads you to this conclusion?
Part B
In a similar way to how you scaled the size of the planets, you’ll also scale the distances between each of the planets and the Sun. The table contains the planets in our solar system and their average distances from the Sun. To more easily compare these distances, you’ll scale them down using sheets of toilet paper.
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Average Distance from the Sun (million km)
57.9
108.2
149.6
227.9
778.6
1433.5
2872.5
4495.1
Scaled Distance (sheets of toilet paper)
5.0
7.6
The ratio between Earth’s distance from the Sun and its scaled distance can be used to find the scaled distance for the other planets. Earth’s distance of 149.6 million kilometers to the Sun is scaled to 5.0 sheets of toilet paper as shown in the table. Now let’s find the scaled distance between Mars and the Sun as an example. Using the calculations shown, Mars’s distance to the Sun of 227.9 million kilometers would be scaled to 7.6 sheets of toilet paper.
d × 149.6 = 227.9 × 5.0
d = 7.6 sheets
Use this same process to complete the table with the scaled distances for the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.
Part C
Using the data from part B, show the distance from the Sun to each planet by rolling out the correct number of sheets of toilet paper. Place each scaled planet you created in Task 1 at the end of the sheets of toilet paper. For example, Earth would be 5 sheets away from the Sun, while Mercury would be 1.9 sheets away.
Now that you’ve created a scale model of the solar system, describe the relative distances between the planets. What patterns, or similarities, do you notice? How do these distances affect the amount of time it takes each planet to orbit the Sun? If possible, snap a photograph of your model. Click the Insert Image button to add your image file (.jpg or other) in the answer space.
Part D
Astronomers believe that there is a large cloud of frozen comets called the Oort cloud, which surrounds our solar system. It lies approximately 50,000 times farther from the Sun than Earth. Approximately how many squares of toilet paper would you need to put the Oort cloud on your model? Explain how you arrived at your answer.
Part E
Check out how large the Sun appears when the Moon is one pixel wide using this online model of the solar system. Unlike this website, we used one proportion, or scale factor, for the planets’ diameters and another scale factor for the planets’ distances from the Sun. Why do you think it is common to use two different methods of scaling for the planet’s diameters and distances when creating a model?
Part F
Compare your finished model of the solar system to the predictions you originally made about the planets comparative sizes and distances. In what ways were your original predictions about the scale of the solar system correct or incorrect? How has your understanding of the scale of the solar system changed?
Reroll the toilet paper for later use. Recycle the paper planets.

On February 7, 2018, a nurse employed at the Flinn Corporation noticed an increase in the number of employees who were sick. She was concerned that there may be a Salmonella outbreak at the company. She has interviewed each of the employees at the corporation. She has taken samples and sent them out for testing but has not received the results. She asks you, the local epidemiologist, to investigate to see if an outbreak exists and if so what the source of the outbreak is. You follow the Center for Disease Control and Prevention’s steps in outbreak investigation (https://www.cdc.gov/csels/dsepd/ss1978/lesson6/section1.html) and report your findings to her. Please note that we will not address all outbreak investigation steps in this assignment.
Use the attached Excel worksheet to produce graphs and statistics to answer the questions below. Submit your report as a Word doc and include figures and tables you generate. The report should be easy to follow and interpret and should be written as an academic paper in proper APA formatting. Please see the grading rubric for additional details on the paper, such as the length for the body of the paper.
1. Look at the Excel Spreadsheet attached. There are 3 worksheets (see tabs on bottom of page – “Nurse’s Interview”, “Epi Curve”, “Retrospective Cohort Study”). The first sheet “Nurse’s Interview” has a line list of employees who work at Flinn Corporation. This sheet represents the data the nurse has collected from those employees in an interview. Do you think that an outbreak exists? Why would you recommend to further investigate? Discuss your reasoning. (Step 2: Establish outbreak)
2. Research salmonellosis using academic sources. Are the symptoms that the ill employees exhibit consistent with salmonellosis? Provide a brief summary (1-2 paragraphs) of the disease and discuss the chain of infection for this disease. Use in-text citations in proper APA format and include all sources in your reference section. (Step 3: Verify diagnosis)
3. Identify the percentage of ill employees with each symptom. For example, 1 out of 12 ill employees had blood in stool (Bs) = 8.3%. (Step 4: Working case definition)
4. Conduct descriptive epidemiology (Step 6). Describe the characteristics of the ill employees to determine trends and risk factors.
a. Person – Calculate the percentage of ill employees that are male/female. Determine the mean age of the ill employees.
b. Place – What percentage of ill employees ate at the cafeteria? What percentage of well employees ate at the cafeteria?
c. Time – Using the data collected in the Nurse’s Interview, fill in the column “# of cases” in the “Epi Curve” worksheet. Use 0 if there are no cases. As you fill in the data, the graph will automatically generate. Choose an appropriate title for the graph. Copy and paste graph into your report. What type of epidemic curve is it ? (Hint: read https://www.cdc.gov/csels/dsepd/ss1978/lesson6/section2.html#step6)
5. Based on the information you have gathered, you have developed an hypothesis that there is a food being served at the cafeteria that is causing the employees to become ill. You need to further test this hypothesis by conducting a retrospective cohort study (Step 8). Use the worksheet “Retrospective Cohort Study” to calculate attack rates and risk ratios. The first food item Baked Chicken is done for you. You can also consult https://www.cdc.gov/csels/dsepd/ss1978/lesson6/section2.html#step8 for help. Report the Risk ratio for each food item. Based on risk ratios, which is food is most likely to be the source of the illness? Explain.
6. Based on your findings, what would you recommend for prevention and control measures? Apply food safety principles from academic sources to discuss further prevention of Salmonella outbreaks in the cafeteria. (Step 11) Use in-text citations and include sources in reference section.
7. Include a properly formatted reference section in APA format that includes at least 3 academic sources (popular sources should not be used).
