Science Experiments

Question: is this like a “1st grade” experiment? please helpp help hel help helppllldglslkfg?

its for a science fair, and all the good topics are taken. suck as static electricity and acids and bases. so me and my partner are making ooze. the one with the cornstarch. is this like a first grade thing. how can i make it more complex. our general topic is Colloids.

Answer: sounds complex enough to me…
i think you should just go with it

Question: Would a ammeter work for an experiment that requires a micro-ammeter?

I wanted to do this experiment I found online where you create a simple solar cell in your kitchen. I went and bought the ammeter we need for it (which cost me 40 bucks) but then i realized it requires a micro-ammeter. Would my experiment still work or can u suggest other experiments using an ammeter. It for our eighth grade science fair and I want to win!
I bought it online so it would be pretty hard to exchange it and the experiment expects 50 micro-amps while my ammeter is a 0-50 scale

Answer: It just depends on the range(s) of the ammeter and the current you are expecting from your solar cell. So long as the current from the solar cell is large enough to register on your ammeter then you should be fine.

Question: Why are my science results so strange? 10ptssss?

So, for my science experiment I did How does the type of drink, with sugar added, affect the time the sugar takes to dissolve?

Answer: A couple of things come to mind looking at your list. If you’re dissolving sugar into any one of the drinks, it would make sense to think the one w/ the least amount of sugar present would dissolve the fastest. But in your experiment, DI water was 3rd (behind cream soda, which should have lots of sugar added) How did you determine the time to complete dissolution? Was it visual? OJ is typically opaque, meaning that you may no have been able to see suspended sugars as well as some of the other, clear drinks – this may have led you to believe a solution was reached sooner than it was. Also, I would expect the carbonation in the sodas to help w/ dissolution too, by agitation.

Ultimately, you formed a hypothesis, tested it, and found results. Try rerunning the experiment, record the pH, and vary temperatures, stirring rate, carbonated vs. flat, the volumes of liquids, and the amounts of sugar added; see if the original results hold up. Also, try running multiple identical experiments (three time in OJ, for example) to see if you’re getting reproducible results. Doing all of this will help you determine what factors truly affect dissolution, and will help you form a more accurate hypothesis.
