Experimental Design B/C

[Phenylethylamine]

Alright, I think I get what you guys are saying. During the first part, the person with experience should be writing up the hypothesis, problem, thesis, etc. (the stuff before the data) while the other two are conducting the experiment. Then, the less experienced one should be recording the data on the graph while the other two are interpreting it and finding the results and conclusion. Is that right?

When I did this event, we did complete parallel processing (after deciding on an experiment together): one person did the beginning, problem-statement part, while another began executing the actual experiment, and the third started the write up (doing the parts that didn't require specific results first, like "potential sources of error" and "related experiments"). By the time the person doing the write up got to actually having to discuss the results, the experimenter would have some data for them.

Typically the first person (doing the problem statement etc.) would finish first, and start cleaning up or help the experimenter finish up their graphs. In your case, it would definitely be the latter, since the experimenter will be the least experienced person and will need the most help. You can still parallel-process to some extent, though.

When I do the event, I do all the writing, while my partners do all the math and the actual experiment. this is good because over time I have had 5 different people be my partners. I have the rubric memorized and have my partners provide me with information.

On my team, people train for each specific part of the event (we have it divided into three particular sections, more or less described in one of my previous posts). I was always the writer for the end part; currently I'm doing Protein, which conflicts with Experimental at our States, so someone else has taken over my part – another person who only ever does the end part. We have other people who are specifically really good at the first and second parts, too, but they would never do the third part.

Before competition, my partners and I meet up and discuss how the parts should be split. Usually, the "problem, hypothesis, conclusion" sort of stuff is one person. "materials, procedure, observations" tends to be the person performing the experiment. All the math is given to one person, who could also participate in the experiment. I like to be well-rounded so if different partners are needed I could fulfill most any roles.

I have found it most efficient for all three of us to come up with an experiment, then I write while they perform the experiment. This works well because my partners aren't always experienced ones.

Yes, this is more or less what I was describing, except that rather than assigning parts before the event at each competition, we have set parts from the moment we start the event (I mean, it's not that set in stone, people have been known to switch, but the idea is that you maintain the same part so you can get really, really good at it over years).

Yes, definitely, working together to come up with the experiment is ideal, because nobody can really do anything else until you know what your experiment is (and you want to spend as little time as possible coming up with the best possible experiment).

lol sorry for the huge quote block. -.-'

I understand that getting really really good at one role has its uses. I suppose that's how your school does it. For mine, the partners switch almost every year, so i guess our method works better. Sort of depends on how the school approaches this event.

True, our method pretty much relies on the fact that the kids doing the event in C Division started out doing it in B Division, so it works best when there's a lot of communication between the junior high and high school teams in a district.

Anyone know how much of the rubric you have to get the points for in order to be competitive (say top 20) at Nationals?(B division)? Does it always come down to tiebreaks? Or is it still good if you only miss a point or two?

At MD regionals we got NO points for our SOC and a half point deducted for my partner not putting units in something (I forget what) but still got first?!

To answer the questions about how to split it up, this probably isn't the best, but I just did everything up to the procedure, my sister started with the stuff after that, and when I finished, I joined her in the analysis and conclusion parts. Our third person was responsible for writing our names and team on each page, drawing the graph, and stuff.

Probably 60/64 of the points... I still need to find out about what we got...
I should email Al Causey right?

I'd ask my coach first, but, yes, you could directly email him.

Well, I don't know about nationals b/c I wasn't in experimental design competition team last year, but you would be surprised at the gaps in scores between teams. The key is to create a simple experiment that is easy to understand, not some lengthy, fancy, advanced one. At regionals a couple weeks ago, we were given a bunch of different powders, salts, and tablets, and then hot water, cold water, cups, a ton of stuff. You know what we did? How long does it take for an alka-seltzer tablet to dissolve

I would imagine at nationals it would be much closer between the teams.

queston to u guys..... What does the ruling mean by the levels of indepedent, dependent, and controlled variables. Need answer ASAP.. Thnx

[zyzzyva98]

Independent Variable is what you change in your experiment.
Dependent Variable is what is affected by that change.
Controlled Variables do not change.

and "independent x axis" is an aliteration
