13 answers

To color code the representation of Arcturus, I used data patterns from Table 2. I assigned a unique color to each element listed, using the colored pencils or markers available to me. I then looked at the inverted peaks on the graph to determine the relative abundance of each element in Arcturus. Elements present in greater quantities had larger inverted peaks, so I used more of the corresponding color in my representation. I planned how I would construct the representation, either by adding color directly to the star diagram or using transparencies to layer colors with the diagram as a background. Finally, I used my plan and selected materials to construct the representation, ensuring that the colors corresponded to the data patterns from the graph and table.
Compare your representation
of Arcturus with the photo of
Arcturus taken with a
telescope fitted with a digital
camera. What advantages
and disadvantages are there
to each type of
representation?
A comparison between the representation of Arcturus and the photo of Arcturus taken with a telescope fitted with a digital camera would reveal advantages and disadvantages to each type of representation.

Advantages of the representation:
1. Clear visualization: The representation allows for a clear visualization of the different elements present in Arcturus, as each element is assigned a unique color. This helps in easily identifying the abundance of each element in the star.
2. Simplified representation: The representation simplifies the complex data from Table 2 and the graph into a visual format that is easier to understand and interpret.
3. Artistic expression: The representation allows for artistic expression, as it can incorporate different design elements, such as layering colors or creating a unique star diagram, which adds creativity to the representation.

Disadvantages of the representation:
1. Lack of accuracy: The representation may not accurately represent the physical appearance of Arcturus, as it relies on color coding and design choices. It may not capture the intricate details and structure of the star captured in a photograph.
2. Subjectivity: The representation depends on the individual's interpretation and artistic choices. Different individuals may create different representations based on their artistic preferences, which can lead to subjective representations of Arcturus.
3. Limited dimensionality: The representation may not capture the three-dimensional nature of the star, as it is typically created on a flat surface like paper or transparencies. This limitation can result in a less realistic portrayal of the star compared to a photograph that captures the star's depth and texture.

Advantages of the photograph:
1. Realistic depiction: The photograph provides a realistic depiction of Arcturus, capturing its appearance as seen through a telescope and a digital camera. It accurately represents the colors, details, and structure of the star.
2. Scientific accuracy: The photograph can be used for scientific analysis and study, as it captures the actual appearance of Arcturus. It provides valuable data that can be analyzed in detail.
3. Non-subjective representation: Unlike the representation, which can vary based on individual interpretation, the photograph provides an objective visual representation of Arcturus, with minimal influence from artistic choices.

Disadvantages of the photograph:
1. Technical limitations: The quality of the photograph may be limited by the capabilities of the telescope and the digital camera used. Factors such as resolution, lighting conditions, and atmospheric interference can affect the clarity and accuracy of the image.
2. Limited interpretation: The photograph may not provide detailed information about the composition or abundance of different elements in Arcturus, as that data would require additional analysis beyond the photograph itself.
3. Accessibility: Access to telescopes and high-quality digital cameras may be limited, making it difficult for everyone to capture a photograph of Arcturus. This limits the availability of photographs for comparison and analysis.

In summary, the representation allows for a simplified and visually appealing visualization of Arcturus, while the photograph provides a realistic and scientifically accurate depiction of the star. Each type of representation has its own advantages and disadvantages, and the choice between the two would depend on the purpose and context of the analysis.
he sun has not burned up all of its hydrogen as Arcturus has. By mass, the
sun is 70.6 percent hydrogen, 28.4 percent helium, and 1 percent other
elements. How would a colorful representation of the composition of the sun
compare to the representation of Arcturus that you made?
A colorful representation of the composition of the Sun would differ from the representation of Arcturus that was made.

In the case of Arcturus, the representation included assigning unique colors to each element and using the size of inverted peaks on the graph to determine the quantity of each color present in the representation. This allowed for a visual representation that indicated the relative abundance of different elements in Arcturus.

For the Sun, the representation would require a different color scheme to reflect its composition. The Sun is predominantly made up of hydrogen, with approximately 70.6 percent by mass. This would be the dominant color in the representation. Helium, which makes up around 28.4 percent of the Sun, would be represented by a secondary color. The remaining 1 percent of the Sun's composition, consisting of other elements, would be assigned a separate color.

In comparison to the representation of Arcturus, the representation of the Sun would have a larger portion of the dominant color (representing hydrogen) and a smaller portion of the secondary color (representing helium). The composition of the Sun is primarily hydrogen and helium, with other elements making up a relatively small portion. This stark difference in composition would result in a noticeable contrast between the two representations.

Overall, the colorful representation of the composition of the Sun would emphasize the dominance of hydrogen and helium, while the representation of Arcturus would showcase the relative abundance of different elements based on the inverted peaks on the graph.
How are composite images an example of multiple lines of evidence, which
