For those who just added the class

We had a lot of fun in class on Friday! If you were absent you really missed out on some fun, but we don't want you to miss out on the assignment as well. In groups of 3, we instructed the groups to take their vial of 5 termites and place them on a sheet of printer paper that has a black line drawn around it with a pen we handed out. Students were instructed to make observations and develop a hypothesis that would explain the phenomena they were observing. Here is a link to a youtube video that shows what most students observed.


So the termites seem to follow the circle drawn on the paper. Why might that be? Some students hypothesized that the behavior is caused by the dark color on the paper (perhaps termites like dark colors). Others hypothesized that the behavior is caused by the indentation that would have been left by the pen. The students then designed an experiment to test their hypothesis. They had various materials available to them (pens, pencils, markers, paper, transparency sheets, etc). We were too limited on time to really spend the time that would be needed to run several different experiments, but collectively as a class we learned the following:
1. It is important, but quite difficult to test for only one variable (i.e. when you use a felt tip pen to test to see if it is the indentation that the termites like to follow, you have changed another variable in doing so: the type of ink used is now different.)
2. The sample size we had in class was too small. Out of the 5 termites we gave to the students, only 3 would follow the line because 1 would get lost and another would have ended up dead from being moved around so much.
3. We are testing for termite behavior, which seems to depend upon the treatment that we apply to the paper. Therefore, the independent variable is what? What is the dependent variable? (come see your TA if you need help with this).
4. It is really important to have a control group for every experiment you conduct. Otherwise, you don't know what your data actually mean.
The assignment handed out was a copy of a "sample exam" that students will fill out and turn in this Friday. The assignment is to write a one paragraph answer to the question "How can the scientific method be used to understand termite behavior?". You must use all of the associated vocabulary terms in this paragraph.

Exam Tips

All of us TA's are frequently asked "How should I study for the test?" It's a question I wish every TA would just address in a straightforward manner so I will do my best to do that here...
What's on the exam?
25 Multiple choice ?'s
2 written questions that will be the exact format as your termite training paragraph.

  • Question 1 will be from Monday or Wednesday of weeks 2-5 (note that week 1 will only be on the multiple choice section)
  • Question 2 will be a Friday question from weeks 3-5. You will be required to write a one paragraph "letter" to your senator describing your opinion on one of the issues. You must provide 2 arguments for whatever side you pick and acknowledge at least 1 argument from the other side. Make sure these arguments are supported! WARNING: You will get marked off for putting "because the government is stupid and shouldn't get involved." or "Only losers smoke medicinal marijuana." Those are just opinions and cannot be supported by evidence.
How I would study for the multiple choice section
1. Make sure to go to a review session! The TA's will go over the vocab terms at these review sessions. This will help clarify confusing terms and be a good refresher for the terms that you haven't heard anything about in several weeks. 
2. Go over the vocab terms again on your own time. Make sure you understand each term well. Be able to define the term and be able to recognize the term if only given the definition.
3. Draw out diagrams, label them, make sure you know how each term relates to the other terms (i.e. how does a synapse relate to an action potential? How do prokaryotes relate to eukaryotes? etc.)
4. Review the slides thoroughly. Do you know why we included each slide? Is there anything that Dr. Cates spent an especially large amount of time on (i.e. gene vs allele).
5. Explain everything to a friend. Make sure you can explain each one of the terms in plain english to a friend or classmate.
6. Go see your TA with any questions! They're here to help you.

How I would study for the written portion of the exam:
M/W questions - Make sure you know how to answer each question. You will need to explain the answer to one of the questions in one paragraph. The best way to prepare for this is to write out each paragraph beforehand and make sure it is exactly what you want it to say. You have the grading rubric... take a look at it! Unfortunately, you can't bring your pre-written paragraph in to the test, but you will have had practice in writing these. If you don't have the time to write each paragraph out - make sure you at LEAST make an outline of your answer. You can go see your TA during office hours if you are uncertain about any aspect of your paragraphs.
Fri questions - 
Review your notes and decide your stance for each of the issues now. Write out your paragraph or at least write an outline.
i.e.  
"Intro: (my stance on the issue is YES)
 Yes Argument 1 (brief explanation of argument)
 Yes Argument 2 (brief explanation of argument)
Additional comments about arguments 1 and 2.
 No argument (brief explanation of argument)
 Why no argument isn't convincing enough to overcome my previous 2 arguments
 Conclusion sentence. "

Finally, some tips for while you're in the testing center:
1. Slow down speed racer. Seriously. If someone said they would give you 5 extra points on the test by staying in the testing center for an extra 20 minutes - would you do it? Well, that's what I'm telling you. I know you might think "I'm a quick test-taker". So am I... and we should totally race sometime! Just not on this test. Take your time with each question and don't get things mixed up! (amino acids/nucleotides, genes/alleles, DNA/RNA, etc.)
2. Draw pictures. You can use a sheet of scratch paper that the testing center stamps to just draw out the processes. This will help you with at least 15 of the 25 multiple choice questions. 
3. Choose the BEST answer. For example, if you see the question... 
What do genes code for? 
a. proteins 
b. amino acids 
c. intelligence 
d. phospholipid bilayers 

You might start to think "I know genes code for proteins BUT proteins are made up of amino acids, so maybe the answer is amino acids? Oh wait, I think I remember reading some part of an article about how intelligence has a genetic component to it as well! So maybe it's that one... Yeah I think I'll pick that one."  and you get it wrong because the best answer here is obviously A. proteins. 

Anyway, I hope this all helps you in your preparation for the exam. Best of luck!

*DISCLAIMER* - This is not a comprehensive list of things to do that will get you an A on the exam. You are responsible for your own studying! This is merely how I would study if I were going to take the test.

Recent News Stories

I love checking the news and finding information about the topics we have discussed in Bio 100. It makes me feel like the class is more worthwhile when you're learning about these current events.

Legal Marijuana Infused Soda
A new marijuana soda is hitting the shelves in California and stirring some controversy.
Some questions to think about:

  • Are these products causing people to put more pressure on their doctors to get them a prescription for it?
  • If you could put marijuana in a beverage - then would it be able to be used as a topical anesthetic? In other words, could you rub a marijuana solution on your arm before getting a shot so it doesn't hurt? Why or why not?
School Lunches and Government Funding

This news story presents another way the federal government can regulate the sale of junk food. Instead of taxing junk food, the government has been providing additional funding to schools who are serving healthier options.
Some questions to think about:

  • For those who think the government should stay out of it completely: If the government shouldn't decide what to feed students at lunchtime... who should?
  • At the end of the segment they talk about the need for additional funding and how the 6 cent increase makes a big difference. Could this additional funding come from a soda tax? Is that taking it too far?
  • Is it more important for an individual to eat healthily as a child or as an adult? What factors would you need to consider?
New Antidepressant With Fewer Side Effects Gets Approval

This last story is about a new Antidepressant medication that got FDA approval this past week. The drug  works the same way as those discussed in class in combination with another mechanism.

Tips for proofreading your paragraph

Proofreading your paper and your exams while in the testing center will DEFINITELY improve your score. I have had several students go from 70% to 100% on the written portion by simply proofreading their paragraph. Here are some tips for doing so:
1. Read the grading rubric beforehand. These are generally the only things we ever take points off for, so make sure you know exactly what those things are. Check course information on blackboard for a copy of the rubric.
2. Proofread your paragraph once for spelling and grammar. You don't want to lose points on the really simple things. (i.e. "protien" is always a common mistake. Protein is correct).
3. Read your paragraph as though you were the TA grading it. Does the student show the TA that they understand how the terms work together? Does the paragraph actually make sense?
4. Double check to make sure you have used every vocab term.
5. Write up a couple of these you feel least comfortable with and go see your TA to make sure you're on the right track!

If you just added the class

If you have just added the class there are several things you need to do to get caught up. Please review these items before emailing your TA.
1. Read the syllabus in its entirety.
2. Register your iClicker
3. Read the previous 2 entries on this blog.
4. Open up the powerpoint slides from the days that you missed and review them. Make sure you focus on the vocabulary terms that are posted on blackboard as well. If there is something you do not understand about the slides, email your TA (you TA is found on the syllabus).
5. Meet with your TA to get a copy of the "termite assignment" and schedule a time to turn it in to them. Also, you will be given the quiz that was due Monday Jan 10th.

Hope that helps!

FAQs

Is this class for me? This course emphasizes application of biological topics. If you need a biology course as a prerequisite for a science-based program (i.e. nursing) this course may not be right for you. Many of the subjects discussed in class have political implications. The course is designed to teach the science behind many current events. Students who do not wish to learn how biology applies to these societal issues would be better off taking biology 100 from a different professor.

How can I succeed in this class? Your most valuable resource for this course is your TA. Students who work closely with their TA are much more successful. Many of our previous students have said “I wish I knew earlier how helpful it was to meet with my TA.” Also, your TA gets paid to meet with you so you shouldn’t feel like you are bothering them or being difficult.

I am confused, what do I have due and when is it due?
Every week your blackboard quiz is due by Monday at 10:00 am. This will begin with a quiz that is due Monday of week 2. You will also have an assignment due every Friday along with a quiz over the readings we post on blackboard. You will have readings for Friday beginning week 2. We will be teaching you how to do your Friday assignment on Friday of week 2, so the first Friday assignment you turn in will be handed in on Friday of week 3.
Any other assignments (test training paragraph, group project information) will have due dates posted on the announcements page of blackboard along with an announcement made in class.
If you are uncertain about what is due, email your TA.

Is there a final exam?
Nope! You will be done with this class before finals week begins. Rejoice.

I am going to be absent. What should I do to get caught up? Prepare for lecture as you normally would with the vocabulary terms. Review the PowerPoint when you are back from your skiing trip/cousin’s wedding/nap and make sure you understand everything on the slides. If there is something you do not understand, go see your TA with questions and they will be able to explain everything you need to know.

When is the test?
It’s on the course schedule on blackboard. Please note the days and times the test is available. Also, please note the testing center’s hours  (testing.byu.edu).

I am going to be absent. Can I get iClicker points? If your absence is university excused, yes. If your absence is related to an illness, death in the family, or other important circumstances, yes. Go see the secretaries in room 109 HRCB and they will give you the iClicker quizzes that you missed from class and you can take them to make up the points.
If you are absent for any other reason (didn’t want to come to class, went snowboarding, etc.) then you cannot make up the iClicker points. Sorry!

I find one of the TA’s attractive. What should I do?
Depends. Some of us are married. Some aren’t. It might be best if you wait until the end of the semester before getting too involved.

I forgot my iClicker. I was in class and was paying attention. Can I have points? Sorry, but no. I get asked this question every day and it is impossible for us to keep track of every student who has forgotten their iClicker and it is not fair for us to give some students points but not others. The easy solution to this is to keep your iClicker in your backpack at all times with a spare set of AAA batteries. The story is the same for broken iClickers, stolen iClickers, and malfunctioning iClickers (This is really rare.) Because most people will forget their iClicker once or run out of batteries we end up throwing out a few iClicker points. See the syllabus for more info on this.

Why do we have those annoying quizzes on Monday?
Great question! I’m glad you asked. Most GE classes have a textbook with assigned readings that you are supposed to complete before class. Generally, the idea is that you become familiar with the subject before it is lectured on so you are able to understand the material better. We want to spend our lecture time explaining things like “how anti-depressants work” rather than spending 20 minutes explaining the definition of “synaptic cleft”. Familiarize yourself with the terms and how they relate to one another and you will do fine on the quizzes. See a TA if you struggle with this.

How do I know who my TA is?
Check blackboard. It says right at the top in bold letters. The TA email addresses are on the syllabus, which can be found under the course information tab on blackboard.

Can I switch Friday sections to be with a friend/ in a different building?
The only way for us to do this is through route y. So unless someone drops, there is nothing that we can do. Sorry!

Do I have to go to Friday section?
If you want the 11 points that come from each Friday and to be prepared for the exams – yes.

But you don’t understand… My BFF’s wedding is on Friday and she will unfriend me on Facebook if I don’t go to the pre-wedding reception planning meal bridal shower event thing. Can I miss Friday class?
As much as we would like to, we can’t play favorites. You can miss whatever you would like to miss, but unfortunately we can’t give you points unless you attend. All early/late work without a university excused absence (or health or family EMERGENCY) gets docked 50% and you won’t be able to make up the quiz. So you will end up missing out on 7 out of 11 points that come from attending Friday and turning your assignment in.

Why don’t we have a textbook? Can I get one if I want?
We don’t use a textbook because we know that 99% of you will sell it back at the end of the semester and never use it again. Instead, we will teach you how to find good reliable biology resources online. You should leave this course knowing how to answer your own biology related questions that will arise in the future.  If you really <3 your textbooks, you can buy one or check one out from the library. We also have some available in the TA lab and on course reserve in the HBLL. Email me for more suggestions about super-awesome biology books.

Is this source I am using for my Friday assignment reliable?
If you are honestly asking this question… probably not. Go see or email your TA to check! Remember, TA’s probably don’t check their email at 2:00 AM the morning before it is due, so it is best to do this well in advance.

How should I study for the exams?
Review the PowerPoints. Write out the paragraphs that answer Mon and Wed questions and review them with your TA. Review your notes from Fridays. Attend a TA review session (the times of these will be posted prior to the exam).

Are Monday quizzes open note?
Yep! However, you cannot work together. We want you to understand the terms we give you. The best way to do this is to look up each term in preparation for the quiz and get a good idea of what it refers to and how it relates to the other terms. We are nice enough to not time the quizzes, so we hope you are nice enough to not cheat.

I am a real whiz with computer stuff and think you should do something differently. Will you implement my idea?
That’s neat. We are always open to suggestions. Please email me your solution and we will consider revising it now or for future semesters. We do know that the technology we use is far from perfect (blackboard, iClickers).

My TA made a mistake grading this assignment/test. Can I get more points?
As it states in the syllabus, you have one week to resolve any grading issues with your TA. So you can - as long as you show it to your TA within a week of receiving the assignment/test grade. After that week is up, we cannot do anything about it.

My iClicker number rubbed off the back. What should I do?
Go to 3704 HBLL. They will work their magic and get you the number for your clicker. Note that 3704 HBLL is only available through the south entrance of the library.

What should I do if my question is not on here?
Email your TA. If it is a personal or private issue – email Dr. Cates. If for some reason your TA doesn’t know how to answer your question then they will forward your email to the appropriate place.

Termite Assignment

We had a lot of fun in class on Friday! If you were absent you really missed out on some fun, but we don't want you to miss out on the assignment as well. In groups of 3, we instructed the groups to take their vial of 5 termites and place them on a sheet of printer paper that has a black line drawn around it with a pen we handed out.

You must use all of the associated vocabulary terms in this paragraph. More assignment sheets will be made available in class today and Wednesday.
