Beautifully explained! Thank you SO much. I’m a middle school Science Teacher and this is a concept many of our students (& some elementary teachers) really struggle with. Your explanation is so straight forward and simplified. Again, thank you. These videos are a goldmine of information!
I watched this for homework and now my recommendation list is filled with science experiments. Hi Mrs.Fliones! (my teacher watches these and plays them in class)
running the same experiment multiple times will generate more data. However it doesn’t guarantee better data. improving the experimental design by controlling for other variables would produce better results. For example, containing the pendulum in a vacuum sealed cube would better control for air resistance variable and produce more consistent and accurate results.
Great videos but I have conducted the pendulum-period investigation many times with students and never found that the amplitude of release affects the period. Always it was the length of the pendulum, assuming all the appropriate controls were in place.
how can you judge whether or not the data is accurate? wouldn’t this require predetermined knowledge of a “correct” result? isn’t the point of the investigation to discover the truth and not be biased by what do you think is correct?

Burning through this series, keep it up!
I have never taught APES and so I can't be much help. Any other teachers willing to lend a hand?

Wonderful clarification for the NGSS.
Omg science 😙😙
Very nice videos. Very useful. Thank you.

Thanks Paul, love the vids!
Lifesaver you are

HI mr. Andersen! Can you recommend a specific textbook that i could use for AP Environmental Science?
Shouldn't the control be constants?
I agree. It would be helpful if you corrected the video to distinguish "controlled variables" from a "control".
good stuff my dude
thx this helped me
Great!⊙
Guess what,
Thank you so much

YOu must do some form of statistical analysis like standard deviation, for starters.
Thx man
oh my GOD I'm so bored. :( I gotta watch it ALL D":
this is so sad can we hit the quaN
