correct and others have evidence to be
incorrect.
• Other scientists consider the results and
conduct other tests and share those results.
• Over a long number of years, the knowledge
grows and changes.
Take Notes!
• You will be making a timeline from the information
in this movie.
• NOTES:
– WHO - people,
– WHAT - contributions to scientific ideas AND political
issues/ gender constraints of the era
– WHERE - country where they conducted their work,
– WHEN - YEAR(s) of effort
– WHY – why was this discovery important?
2/28/13
• Entry Task
• What is a TIMELINE?
Discuss Answers
• A timeline is a graphic representation of the passage
of time as a line. Either vertical like facebook or
horizontal…
• EXAMPLE
• http://1.bp.blogspot.com/-zr2MhuoWfg/T6BQf69mDLI/AAAAAAAACmk/l_QQlVJsis/s1600/Timeline_Inventions.jpg
• Often, past on the left…current on the right.
• Remember the spaces on the timeline should be
even. For example if you want to span 200 years over
10 inches, every inch would be 20 years.

Answers
•
•
•
•
Average SPEED = Distance/time or
distance PER time
The word per also means “divided by”
This is AVERAGE SPEED because it tells you
nothing about acceleration during that time.

Answers
• REFINE means to edit or take the “junk” out
and only leave the best
• Constructive feedback means positive…you
can sandwich: positive, little negative,
positive….
• Think before you talk and phrase carefully so
you don’t hurt feelings
Cartoon Peer Workshop
•Groups of 2 or 3
•Each person present draft storyboard–
explaining motion and ideas, and what you plan to add
•Suggest what feedback you are looking for –
For example, help representing the laws, or help with your storyline, or help
with the artwork itself, or help with the dialog, etc
•Each listener will jot down some notes or comments for constructive
feedback on the pieces of scrap paper.
•Do be respectful and follow workshop guidelines!
Peer Workshop Etiquette
• All comments have to be constructive. No trash
talking allowed.
• You have to comment on the work in front of you,
not what you would have written if it had been
your idea. Even if you think your idea is better.
• Don't try to rewrite for the author. The author
can do that him/herself. Just point out the areas
of concern.
• (borrowed from Meir Ribalow of a NYC playwright’s group)

4/26/13
• Entry Task
• Say Something Nice
• Please turn in your entry task sheets!!
• Finish WHITE and PURPLE sheets TODAY!!
4/29/13
• Entry Task
• What is a good R/A for the conclusion on the
back of the purple?
• What is the data high? Data low?
• What is a good “S”? (this is the scientific
explanation which compares high and low
data).
ANSWERS
• R/A – The number of salmonberries is greatest
at the forest edge and least in the forest.
• Data High – Forest Edge had 24
• Data Low – Forest had 6
• S – The forest edge has on average 18 more
than the forest. This might be because the
forest has the most shade and salmonberries
need some sun.
Today’s Work
• Write your conclusion and turn in your purple
sheets.
• Start and finish the pink sheets.
• Flip through and check what you’ll need to do.

MSP. See you Thursday for Science MSP!!
4/30/13
• Entry Task
• Read “A true Story?” on page 67 of the Pink
books.
• Which will hit the ground first, a heavy or a
light object?
• Read pages 62-71 in pink books.
Answers
• The heavy and light object will hit the ground
at the same time. I know this is true because
in the text it states, “…they crashed at the
same time. The idea was to prove that objects
all fall at the same rate.”
5/1/13
• Entry Task

rate?

tlaws/u2l3e.cfm
• http://www.physicsclassroom.com/mmedia/n
ewtlaws/efff.cfm
ANSWERS
• Objects of different masses FREE FALL at the
same rate BECAUSE acceleration due to
gravity is always about 10 m/s every second.
• SO, a heavy thing falls 10 m/s faster every
second and so does a light thing.

Pink books.
• Which will hit the ground first, a heavy or a light
object?
• Watch and listen to demonstration…
ANSWERS and 8th grade work:
• The heavy and light object will hit the ground
at the same time. I know this is true because
in the text it states, “…they crashed at the
same time. The idea was to prove that objects
all fall at the same rate.”

5/15/13
• Entry Task
• How do you think electricity “flows” or moves
through a wire?
Answers
• It must have something to do with metal
because electricity flows through metal best.
• We think it might move as a wave because EM
is waves.

5/20/13
• Entry Task
• Make a prediction (hypothesis):
• How does the number of coils of wire (6 vs 12)
affect the number of paper clips you can pick
up with your electromagnet?
8th Grade Hypothesis
• If there are more coils
• Then there will be more electrical fields in the
area causing more magnetic fields
• Because as the electricity flows, it also creates
magnetic fields.
Hypothesis
• If more coils are put on the nail
• Then it will pick up more paperclips
• Because more magnetic force will be created
from the coils.
Finish Electromagnet Activity and Q
