PHX 3.1 Investigation Internal

what are the uncertainties for a stopwatch, electronic balance, and ruler

0.01s, 0.01g, 0.6cm

how many controlled variables do you need

they look for 1 but you should write 2-3

what are the 6 things you can write BEFORE collecting data

IV, DV, CV, y=mx+c, theoretical gradient, theoretical y-intercept

what are the four columns of the small table

IV (manipulated), uncertainty in IV (manipulated), DV, uncertainty in DV

how do you calculate the manipulated IV uncertainty

equipment uncertainty % IV x exponent x manipulated IV

how do you calculate uncertainty in DV

max-min/2 + equipment uncertainty

what are the six equations you need to give in your conclusion

line of best fit, error line, uncertainty in gradient, uncertainty in y intercept, unrounded final, rounded final

how do you write the “explanation” (comparing theoretical to experimental)

The theoretical gradient of ___ does/not fit within the range of the experimental gradient (__ to __).

what are the key points for your discussion paragraphs

what, why, over/underestimation, change in graph, link

what goes on your graph axis?

manipulated variable, manipulated unit. DONT FORGET TITLE
