In science class on Tuesday, the first thing we did was correct our homework (the speed problems sheet #2). The answers to it were:
- Formula: s=d/tPlug: s=367km/8h
Chug: s=45.88 km/h - Formula: s=d/t
Plug: s=113.45m/4.7h
Chug: s=24.14 m/h - Formula: d=s*t
Plug: d=31 m/s*25 s
Chug: d=775 m - Formula: d=s*t
Plug: d=303 km/h*5.5 h
Chug: d=1666.5 km - Formula: t=d/s
Plug: t=5832 km/913 kmph
Chug: t=6.39 h
*** We had to convert: 5,832,000 m = 5,832 km - Formula: d=s*t
Plug: d=15,120s*6.8 m/s
Chug: d=102,816 m (1028.16 km)
***We had to convert: 4.2h=15,120 s
- Write an answer to the purpose question: "How does the distance an object is dropped affect the time it takes the object to fall?"
- Make a list of the data from this experiment that supports your answer to #1. In other words, make a list of the data that will convince Ms. D you are right.
- Make a list of scientific facts/theories/explanations that support or explain your answer to #1. (Hint - your textbook or Google doc may help!)
- Describe what is happening on your graph. Be sure to use scientific vocabulary and numbers to support what you are writing! (5 sentences min.)
- What are four specific errors you might have made in this lab?
We made line graphs, and we also talked about positive and negative correlation, and about how distance affects time in our lab.
- Positive correlation is when the x axis of a graph increases, and the y axis also increases.
- Negative correlation is when the x axis increases but the y axis decreases.
- No correlation is when there is no pattern at all. (scatter plot)

JAMES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
HAPPY
THANKSGIVING!!!!!!!
(Video made by me)
Nice video at the end!
ReplyDeleteHappy Thanksgivig to everybody out there!
I noticed a couple of things.
The first thing is that at the first answer you gave the formula and plug on the same line, which looked weird.
Second, the yellow color is a bit to bright.
Third, the turkey looks delicious!
Really good
ReplyDeletei really liked that you put the answers too the speed problems sheet in different colors.
Another thing i also liked was that you explained the correlations of graphs.
One thing i saw was that you put the plug together with the formula on the same line.
Nice turkey!
Great post
ReplyDeleteA thing that could have made your post even better is before the answer to the speed problems you could add the question.
I enjoyed the video a lot. After you saying think about motion and showed the train a random fact came to mind.
At the first showing of motion pictures the entire audience fainted because of a train coming right at the on the screen.
I thought it was great how you explained positive, negative, and no correlation. In case anyone is having trouble understanding it, though, here is a video that helped me.

I hope this helps!! Good job...loved the thanksgiving video!

ReplyDeleteHey there Viktor - LOVED the video and that you got motion into the act!
ReplyDeleteYou have some good comments on here 7th Graders - love the random fact Bryce, nice suggestions from Antonia and Kat and the video link was a great idea Fabi. It is clear, used the same terms as we do in class and the speaker is understandable! Excellent choice! Nice work folks!
Wow Viktor!!I knew that you would do a great job. I really like the colors and the F/P/C. The video was really cool! I also thought you explained it very well =)

I think you did a good job with all the different colors, but for the next time do not use yellow, because it is hard to see.
Also, I think it would have helped if you wrote the questions from the sheet speed too, because in case anyone was missing from school that day, they could see the questions and catch up!
Awsome post!
