Re: Food Science B
Hi there,
@coachmom, good that you've scoured the wiki! FYI, I have changed the Food Science article drastically in the last week.
I see your problem now--we've had that problem. My only suggestions are:
1. Go out and buy absolutely fresh stuff. (Our corn syrup was too thick because it was old. New corn syrup worked!
2. Make sure room temperature is the same.
3. Do not heat it to cheat! Unless you can do the absolute same at the contest, do not! In other words, it's not going to help your graph.
4. Make sure it's Karo Corn Syrup, Dark or Light.
5. Remember you're cutting the time when it breaks flow, not when it all runs out.
If all fails above,
6. Do not include this point on your graph. You should not get points off for this.
@AKTU01, First plot your graph the way you have it first. Now click on one of the points in the graph. Right-click on it, and Insert Trend Line or something similar. Now right click the trend line and click format trend line. Now you can select the trend line to be a curve. (Alternatively, you could have a straight trend line, but this competition wishes for a standard CURVE.)
Another bashy solution is to print it out and draw a curve generally following the trend of the points.
Hope it helped both of you,

Re: Food Science B
Thanks, we were wondering about that as well, but what brand and type of molasses have you been using? We've been getting consistent times for the corn syrup, but our molasses times have been going all over the place depending on the type of molasses and the brand, and none of them have seemed to fit in with the rest of the data.knittingfrenzy18 wrote:Hi there,

Re: Food Science B
I'm not sure it matters--we used "Grandma's"? I forget the name exactly. It has a orange yellowish wrapping.
Also make sure the room temperature is constant, no one's using the microwave. Expect the higher viscosity to get a little more all over the place.

Re: Food Science B
Hey, I had my state comp yesterday, and my partner and i didnt know the answer to this question:
What is the common chemical formula for a carbohydrate compound? Or something along those lines... Does anyone know the answer?

Re: Food Science B
Well, all carbs you've seen probably had the formula CxHyOz. THen we look at Wikipedia to check that, and we find...Cm(H2O)n as the general formula of a carbohydrate. Think that was the answer?

Re: Food Science B
Yes, the best general formula is where most commonly and are the same number.
