NB 2: Identify one form of energy and where it can
be seen your life.
Agenda:
• Work in groups to identify forms of energy seen
in various photos.

Monday, August 26th
LT 1: I can identify the different forms of energy.
LT 2: I can identify where energy conversions occur
in a system.
Agenda:
• Go over learning log feedback.
• Officially define the term energy.
• Discuss the conservation of energy.
• Try to identify where energy conversions take place
in a sample activity.
Homework: Roller coaster Energy reading and
questions.
What is Energy?
We have identified many forms of energy. We
know that energy can be stored for future
use (potential) or in motion (kinetic). But
what IS energy? All energy allows work to be
done or causes a change. Therefore, we
define energy as the ability to do work.
Page :
Energy is the ability to work.
Energy Flows
A major idea in science is the Conservation of
Energy. What this means is that energy is
neither created or destroyed. It simply converts
to different forms. Energy does not get “used
up,” it gets changed from one form to another.
In the case of chemical potential energy,
sometimes some help is needed to cause the
conversion. This help is provided in activation
energy.
Identifying Energy Conversions
Today you are going to work with a bag of
materials. You have one goal: Identify any
energy conversions that you see take place
while you play with the materials. You will
be sharing your findings with the class
tomorrow. Please turn to page 4 of your
notebook. We are going to create a data
table to record observations.
Rules
During the exploration:
1. Treat the equipment respectfully and gently.
2. Stay at your own seat.
3. Work only within your group with the
assigned materials.
Tuesday, August 27th
LT 2: I can identify where energy conversions occur
in a system.
Agenda:
•Go over homework.
•Go over energy conversions from yesterday. We
will make any changes in notebooks.
•Define Conservation of Energy in notebooks.
•Energy conversion practice sheets.
Homework: NONE… but, you should begin
reviewing flashcards nightly.
Roller Coaster Energy Questions
What makes a roller coaster move?
How does a roller coaster gain gravitational
potential energy?
Roller Coaster Energy Questions
At what point on the track is the gravitational
potential energy greatest?
What happens to the gravitational energy as the
roller coaster car beings to go down the first hill?
Roller Coaster Energy Questions
Not all energy is transferred to the kinetic and
potential forms. What does some of the potential
and kinetic energy also get transferred into?
Conservation of Energy
P6
The Law of Conservation of Energy: Energy is
neither created nor destroyed. Energy is
converted from one form to another.
Wednesday, August 28th
LT 2: I can identify where energy conversions occur
in a system.
Agenda:
•Mini Assessment over LT 1.
•Discuss variables. Define in notebook.
•Begin collecting data for Energy in a bouncing
ball.
Homework: Energy and Power sheets. These are
due on FRIDAY
Variables
Variables are what get changed in an
experiment. Only ONE variable should be
changed in an experiment. That variable is
called the independent variable. The variable
that gets changed by the investigator should
affect one outcome, called the dependent
variable.
Variables
P8
Independent Variable: The variable
changed by the investigator. (I change
it ☺)
Dependent Variable: What gets affected
by the independent variable.
