Intro to Gravity POE
Warm Up:
1) Describe what causes all
objects to fall towards
the center of the Earth.
2) Is there ever a time that
gravity does not work?
CW:
1) Warm up
2) Gravity POE
HW:
1) None
How does POCER Work
P = Predict
You are going to write down a prediction of what you
think is going to happen in the demonstration.
O = Observe
You are going to write down an explanation of what
happened as well as draw a picture of what happened.
R = Explain
You will attempt to explain what you just witnessed. It
will be in the form of answering questions the teacher
provided as well as a summary that you generate.
The $1 Challenge
Do you think you could catch a $1 bill?
Why do you think it was impossible for the student to
catch the $1.00 bill.
(The Earth's gravitational pull makes this challenge
impossible to win. As you release the currency and your
student closes his/her fingers, the currency has already
passed through the fingers.
Different Objects
Do you think all objects fall at the same rate?
Which object do you think will hit the ground first, a
tennis ball or an empty soda can?
Why did these objects hit the ground at the same
time?
I’m Free Falling
What happened to the water when you took your finger
off of the cup?
What happened to the water when you dropped the cup?
Why do you think this happened?
Write the terms “Free Fall, Gravitational Pull and
weightlessness.”
You and your table groups attempt to come up with a
definition to define each term.
(The gravitational force pulls the water through the hole
in the container as long as the container remains
motionless. But when the container is set in motion
(dropped) and allowed to free fall toward the empty tray,
the water remains inside the container because there is an
equal amount of gravity being exerted on the container
and the water inside the container.)
Exit Ticket
Explain why Scientists and Humans care about
Gravity. Why is it something important that we think
about?
Gravity: It’s Grreeaatt!!!
Warm Up:
1) Is there ever a time when
you feel gravity pulling
on you with a stronger
force? Explain when you
might have felt this.
CW:
1) Warm up
2) Gravity Video
HW:
1) None
3-2-1 Classroom Contact,
Episode #22: "Gravity"
We are going to begin watching a video about
Gravity.
Your task is to fill out the worksheet as we go
through the video.
Exit Ticket
Describe a time and/or a place when a person can feel
weightless and extremely heavy simultaneously.
Explain why the person would feel this way.
Space Weight
Warm Up:
1) If I were to leave Earth
and go to a different
planet, would I weigh the
same? Why or why not?
CW:
1) Warm up
2) Space Weight
HW:
1) None
Space Weight
You will need to log into Mr. Sutphin’s web page
(sutphinscience.weebly.com) and click on the 6th grade tab.
Once on the 6th grade page, click on the Scientific Inquiry and
Lab safety tab.
Scroll down to the bottom and click on the Space Weight Tab.
You will then need to calculate your weight on each planet and
star as well as the # of G’s exerted.
When you are done with your calculations, you need to take
notes on the “What is Going On” section of the website.
You can take your notes on the back of your worksheet.
You need to create a bar graph for each planet using their
personal weight data.
Space Weight wrap Up
Warm Up:
1) Do you weigh the same
on all of the planets. Yes
or no and why?
CW:
1) Warm up
2) Space Weight
HW:
1) None
Space Weight Article
With your lab group, read through your notes and
come up with 3 main ideas from the article. (What
are the three most important things that you think
the article wants you to understand)
Most important ideas
from your reading.
Mass is a measurement of the amount of atoms/matter
Mass attracts Mass ( like to magnets have an attraction)
The amount of attraction depends on the size of the masses.
Like the sun would have WAY more attraction then Pluto
because of the masses.
Scales measure the force of the attraction ( pull to the
center of the earth)/ the amount of the gravity pulling upon
you.
Planet Graphing
On a piece graph paper, create a bar graph of your weight
on all of the planets and Dwarf planets in our Solar
System.
Answer the following questions at the bottom of your
graph:
1.
2.
3.
What trend do you notice with your weight when
comparing all of the different planets? (Are all of the
planets the same size)
What do you think causes the difference in weights?
Compare and Contrast the words Weight and Mass.
1.
(How are they similar and how are they different)
