We then had a very pleasant surprise: a shootout between Ben, Brandon, and Kaitlin, aiming at a target on the screen using Mr. Lieberman's handy-dandy uzzi-- which is a gun for those of us who don't know. The competition went smoothly except for a single misfire, which thankfully did not harm anybody. The result was a tie between Brandon and Ben each with one point, and Kaitlin in second with zero.
now a few definitions:
- Accurate: hitting what you are aiming for (the target)
- Precise: being consistent every time; your work is reproducible
Other than that, today was a typical day in the classroom: lecture notes.
We now (in theory) know the metric system: 1g=10dg=100cg=1,000mg=1,000,000um (micrograms)=1,000,000,000 ng=1,000,000,000,000 pg=.001 kg.
The hierarchy of metric prefixes goes like this:
kilo=1000
(none)=1
deci= 1/10
centi= 1/100
milli = 1/1,000
micro= 1/1,000,000
nano= 1/1,000,000,000
pico= 1/1,000,000,000,000
And there is mega and giga and tera, but if you care about those, you probably know what they mean.
We also learned about temperature: Scientist use celsius, in some cases they use kelvin, we use farenheit. The conversion equation is: t(f)=9/5c+32. The way I remember it is how to get from 100 to 212 using 9/5 and 32: multiple by 9/5 to get 180, add 32 to get 212, maybe that helps.
And last but probably not least, taking measurements: Always estimate one digit past the last readable digit. So that means if you are measuring in millimeters, you want to measure to the point "x". If a box happens to be about 11 mm, plus a tiny bit, you would record 11.1 mm.
If you did not understand this I am embedding the notes for todays lecture here:
YUS, it worked. If you do not understand, comment.
This is Matt P, and always will be.
Michelle T. you have been privileged with the honor of being our next scribe.
