New Unit - Energy
• Create a new Energy AHA
Connections Visual Outline
on pages 46 and 47
• Turn your comp book
sideways and create an
Energy KWL chart on page
48
• Create a new unit page for
Energy on page 49 by
writing the word “Energy”
in the center of the page.
Fill the remainder of the
page with words and
pictures that come to mind
when you hear the word
“Energy”

Roller Coasters
• Watch the roller coaster from:
http://www.funderstanding.com/coaster
• Answer the following questions:
1. Why didn’t the roller coaster make it all the
way through at first?
2. What could you change to make it work?
(include all possibilities).
a
Roller Coaster Project
 Challenge: design and create a roller coaster that lets the
marble travel all the way through.
 Requirements:


Marble must land in the cup at the end of the roller coaster
Have at least 1 hill and 1 loop
Include a diagram with PE and KE labeled
Record the length of the roller coaster, time it takes for the
marble to go through it, mass of the marble, and height of the
first hill
Calculate speed of the marble, and potential energy using
formulas.
Conduct 5 trials
Answer the conclusion questions
Create a poster showing your design and how you have applied
your understanding of potential and kinetic energy

Forces on a Roller Coaster
• What forces are acting on the roller coaster
that might affect its speed?
 Friction
- due to surfaces touching
- the frictional force on the roller coaster is
between the track and the marble.
This arrow represents friction. It
is pushing against the
movement of the roller coaster.
- Air resistance may also be included here
 Gravity
- due to the pull of gravity to the center of the Earth.
- the gravitational force pulls the marble down
 Be prepared to draw arrows representing
friction and gravity on your roller coaster poster
This arrow represents gravity. It
is pushing down on the roller
coaster.
Representing K.E. and P.E.
 Use a bar graph to represent potential energy
(PE) and kinetic energy (KE) at different places on
the roller coaster.
At point A, a bar graph for PE
and KE would look like this:
A
C
B
D
What would a bar graph look like
for points B, C and D?
 Be prepared to label important areas for PE and KE
on your roller coaster poster.
