for the 1st one, it was an experimental error. Just one of the rubric points says data collection. and we didn't have 0 DV or IV but the line breaks were still incorrect :/
Hmm, I don't see a problem with your explanation of the error... then again, maybe the proctor was just harsh?
Did you describe the error and explain how it affected the data?
"artificially inflated the data (made the values for time too high)"

"artificially inflated the data (made the values for time too high)"
Describe as in human/random/etc error

For example,
The data was collected by a manually operated stopwatch read by eye, so human reaction time may have artificially inflated the time recorded. Due to the limited precision of a human being, this can be best described as a human error.

It's not really on the rules, but it's kind of given (I guess?). Maybe the grader was just tired of grading tests and graded based off word choice/sophisticated-ness/whatever.

Yup, it was described as human. We split our paragraphs into equipment, human, and built-in errors. We were also DQd at that event tho SO maybe they just didn't care anymore. Thank you anyway :)

My question is more about the "important info about data collection" rubric point, since it seems we had it explicitly stated. how do you usually satisfy this?

Does anyone know how to write a standard of comparison, like what qualifies as one. We always just use the control group thing, and that part is one that we have struggled on in the past two competitions. Thanks! :)

The control group is the standard of comparison. You have to make sure that it is a part of the experiment with the manipulated variable being unmanipulated. For example, a pendulum experiment with a cup and marbles would have their SOC be the cup without any marbles. In experiments where this is harder to define and the manipulated variable is not a quantity, but a type, you have to choose the one that is most "neutral." For example, a paper airplane with copy paper, tissue paper, and card stock would probably choose the copy paper because it is medium thickness and would have an air resistance in between that of the other types.
Last year I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Now I know stuff about amphibians, reptiles, water, and more experiments, yay again!
I'm planning to learn stuff about oceanography, fossils, and more water, yay for the third time!

Hey, does anyone have new prompt ideas to practice? My partners and I have been stuck in a rut of pendulums, rolling/bouncing balls, and properties of water (these are pretty much the only prompts at the invitational level, but that's besides the point) and we need to practice more experiments.

One prompt I had was with a seesaw. It was pretty fun.
