"If we show matched and mismatched colors and words to students, then it will be harder for the students to identify the mismatched ones because it will confuse them a lot." This is a very effective hypothesis.
True
False
True and False
If we show mismatched colors and words to students, then it will take them a longer time to figure out correct match of words and colors. The independent variable is
mismatched colors
mismatched words
mismatched colors and words
time it takes for the students to find a match
If we show mismatched colors and words to students, then it will take them a longer time to figure out correct match of words and colors. The dependent variable is
time it takes to figure out a match
mismatched words and colors
mismatched colors
mismatched words
"Stroop Effect is not that hard for some students. Our hypothesis was both correct and incorrect. Things we can improve on would be our behavior. My group and I were loud and playing around. One of our group members did his own experiment. Next time we do this activity, we will make sure that we follow all lab safety rules." Is this a good lab report conclusion?
Yes, because it has all the parts
No, because hypothesis is undecided
Yes and no, because the experiment is invalid
"Student A had a time of 20 seconds then 35 seconds. Student B had a time of 40 seconds then 45 seconds. The students did 2 trials." Why are multiple trials important?
to get believable data
to get perfect data
to get reliable data
to get a good grade
"If we combine glue, water and borax in correct order, then we will create Gak." Is this an effective hypothesis?
Yes, because it has if and because
No, because the variables are not specific
Yes and no, because it's short but unclear
"If we combine glue, water and borax in correct order, then we will create the best quality Gak." Identify the independent variable
best quality Gak
glue, water and borax
correct order of glue, water and borax

"In conclusion, my bottle rocket was successful in its launch on it’s final trial. One thing that I could’ve done better with my first trial was making the parachute smaller. Something that I could’ve done better was making sure my parachute was well strapped onto my bottle." Is the lab report conclusion complete?
Yes, it has all the parts
No, it's missing hypothesis
