Experimental Design

[haven chuck]

Wow, that sounds very difficult to think of and to execute. nejanimb, Did they tell you what to do or did you have to come up with that experiment?

[Avis_de-Incendia]

Lol, I just thought of that off the top of my head.

I feel smarts now! :3

You should feel smart because that's one of the most creative ideas I've ever heard of; I just assumed the paper was for the write up. Imagine me trying to measure bubbles floating around randomly in the air.

[nejanimb]

That's exactly what we did. We did the height above the paper where the bubbles were blown as our independent variable, and the diameter of the spatter mark as our dependent variable.

They gave several suggests as to possible ideas, including velocity of waving the wand, and all kinds of strange things. You still had to come up with your own actual strategy and experiment though.

I would of done how long it takes for different sizes of paper to dry when soaked in water.

[Avis_de-Incendia]

Well, after taking that idea, I think i can write the procedure...

1. Take bubble wand and place in bubble solution.
2. Blow softly into the bubble wand as to produce only 1 bubble.
3. Take 1 sheet of paper and pop the bubble on to the paper; this will leave the "imprint" of the bubble.
4. Measure and record the diameter of the bubble.
5. Take 1/4 cup water and pour into bubble solution.
6. Repeat steps 1-4 with the new bubble solution.
8. Repeat step 5-6 until water is all gone.
9. Analyze data.

Well? What do you guys think?

[yoyosciencekid23]

wow
that is a good lab

but this event irks me now in PA
we got 34 out of 35 teams.

[Avis_de-Incendia]

Well, it's a really popular event.

[EastStroudsburg13]

Oh, trust me, it's not the easiest thing in the world. We got 14th, which isn't too bad when you think that we only had 2 people and we were both freshmen.

Well it isn't bad but it would have helped and made it easier if we had and extra person who could help with the writing or experiment because if we did, we might not have had to rush as much.

Yeah, I know. It's not like no one else was free...I think....I actually thought we did better than that though. Maybe the stuff was too short because we didn't have enough time.
