Star Obituaries (assigned 03/25/2014)
An obituary is a way to honor the passing of a loved one. Obituaries are often published in local newspapers to inform the community of the passing of one of its members. It is a way to announce the death of a loved one so that everyone who would like to honor that person can come participate in the funeral services. Obituaries provide a summary of a person's life, their time and date of passing, their legacy or some key highlights about their life. You can read more about how to write an obituary here and look at the sample obituaries posted there.
YOUR TASK:
Pick a star from the HR diagram picture below (from the Light and Stars Review questions assignment) or research the name of a supernova, planetary nebula, or black hole. You will write an obituary for its future death. Your obituary should include the following information:
You will obviously need to conduct research on your star, so make sure to CITE YOUR SOURCES!
Remember you are using the literary device of personification here, so you should write this stellar obituary as if the star was a person. You should also follow the proper format for writing an obituary.
Also include a picture of the star (cite the source of your photo). Feel free to use your mad photoshop skills to make it look like an obituary-worthy picture or personify the star.
DUE MONDAY MARCH 31st, 2014

Nature of Science Meme (assigned 09/13/2013)
Considering our discussions on the Nature of Science the last few days, you are to create a Nature of Science Meme that embodies one of the following aspects of how science is done in the real world:
In addition to the meme itself, you are to write a WELL-DEVELOPED, one paragraph (about 7-10 sentences) answering the following questions. Remember your paragraph should have a topic sentence, details and an explanation that follow logically, transition words and sentences, and a concluding statement:
YOU CAN UPLOAD BOTH FILE DOCUMENTS ONTO THE SAME ASSIGNMENT SUBMISSION FORM BELOW!
DUE WEDNESDAY SEPTEMBER 18th, 2013
- Scientists's opinions, biases, and personal beliefs influence their research
- A scientific idea is not valid in the scientific community until it has stood up to the scrutiny and critique of other scientists
- Scientists can look at the same set of data and come up with different, valid interpretations
- Scientists will critically assess and evaluate each other's work, even if they agree with the results of that work.
- A scientist may not always get the results they were expecting but that does not mean they are a bad scientist. It is important that they critically analyze their results and attempt to find explanations for it.
- Science is not universal and it is affected by the culture in which it is practiced.
- The scientific method is not a rigid process, and often the scientific process can be messy, repetitive and sometimes seemingly random.
- Science is not able to prove and disprove theories, facts, and laws once and for all.
- Communication, written and spoken, is an integral part of science.
- Collaboration with each other is a vital aspect of doing science.
- Skepticism is an innate and important part of scientific inquiry.
In addition to the meme itself, you are to write a WELL-DEVELOPED, one paragraph (about 7-10 sentences) answering the following questions. Remember your paragraph should have a topic sentence, details and an explanation that follow logically, transition words and sentences, and a concluding statement:
- What aspect of the nature of science did you choose to represent in your meme? Why?
- How does your meme convey this message? Why'd you pick the images and captions to convey that message?

1. Introduction: What was the problem and what was the purpose of the lab (why do we care about how much water a gummy bear can soak up or how much its volume would increase if soaked in water)
2. Procedure:
Please finish writing up the exact protocol for how you are going to measure the volume of the gummy bears in our Gummy Bear lab activity. In addition, please neatly organize your initial volume data and observations into a well organized, clearly labeled chart.
REMEMBER! Your protocol SHOULD:
- BE VERY SPECIFIC AND CLEAR (don't just tell me "measure the volume of gummy bear" because that could mean any number of things. Furthermore, that's the whole point of your procedure, you NEED to tell me EXACTLY HOW you're measuring the volume of the gummy bear")
- Have a RATIONALE/JUSTIFICATION. (i.e you need to answer the question Why does your procedure of measuring the volume make sense...how is what you're doing actually measuring the VOLUME of the gummy bear and not something else. Keep in mind the definition of what "volume" is). Here are some questions to consider when writing your protocol and justification:
- What instruments did you use?
- Why are you using those specific instruments/tools/materials (also consider how the aspects of size of the tools, accuracy, electronic capabilities, etc.)
- EXPLAIN EXACTLY HOW your method is measuring the entire VOLUME of the gummy bear as opposed to another aspect of it, like how many atoms it contains or it's water content, etc.
- What downsides/pitfalls or inaccuracies might be plausible with your particular method?
- Be neat, legible, easy to read and follow (preferably typed).
3. Observations and Data:
- Please organize all your observations and data into NEAT, TYPED and ORGANIZED tables that are CLEARLY LABELED. (You may need to have more than one table. In fact, you SHOULD have more than one table). Remember, if you're using the "v= L x W X H" formula for the gummy bear, you MUST multiply out all the dimensions to get one quantity for the volume of the gummy bear.
- Please also show all your calculations to determine the PERCENT CHANGE in volume for EACH gummy bear.
- Example: See attached document below
4. Conclusions:
- Use the questions on your handout to help guide you as to what kind of thoughts you can include here.
- What can you say about the gummy bears and their abilities to retain water? What patterns did you notice?
- What was the process like in trying to determine the best way to measure the volume and in collaborating and working with your group? Do you think you all worked well in your group?
Please submit an electronic copy to the assignment form below, AND print out a version too.

For your reference, the following is an example of what well-written Protocol and Justification section would look like (DO NOT SIMPLY COPY AND PASTE WHAT IS WRITTEN BELOW, YOUR PROTOCOL MUST BE WRITTEN IN YOUR OWN WORDS):
*Note: The protocols listed below do NOT necessarily mean they are correct protocols to measure a gummy bear's volume. They are just used to merely provide an example.*
Example Protocol and Justification:
*Note: Notice how these examples address each of the purple questions listed above in your assignment instructions.*

*Note: The protocols listed below do NOT necessarily mean they are correct protocols to measure a gummy bear's volume. They are just used to merely provide an example.*
Example Protocol and Justification:
- Using a 12-inch ruler, measure the length (head to toe of gummy bear), width (arm to arm of gummy bear) and depth (back to belly of gummy bear) of each gummy bear in centimeters (cm).
- Rationale/Justification: The accepted formula for volume is length x width (depth) x height. This is because volume is the measure of the amount of space an object takes up. Space is measured in three dimensions: length, width (depth) and height. Thus, it follows then, that the formula for volume would be a combination of all three of these dimensions. Measuring these three dimensions of the gummy bear is logical because the gummy bear is a 3-d solid object and these dimensions are easily measurable on the surface of a gummy bear. We decided to use a ruler to provide our measurements because a gummy bear is large enough to be measured against a ruler, but small enough that a centimeter scale is necessary. One possible pitfall with this method is that because gummy bears are irregularly shaped objects, the calculation of the gummy bear's volume might be slightly skewed because it does not take into account the irregularities and unevenness of the gummy bear's exterior.
- Rationale/Justification: An electronic scale would be suitable because... . It is important to measure the weight of the gummy bear because... ./Measuring the weight of the gummy bear tells us about the volume of the gummy bear because... . Some possible errors with this method include:... .
- Rationale/Justification: We are using a 100mL graduated cylinder and not a 200mL graduated cylinder because... . Observing the change in water level in a graduated cylinder tells us about the volume in a gummy bear because... . Some disadvantages to this method include... .
