1. Where does energy come from?
2. How did you get energy today?
3. What is the source of all energy
for plants and us?
Energy Unit- Target 1
I can describe different forms of
PE and KE energy.
Agenda:
1. Bell Ringer 3 Q&A’s
2. Power Point Notes – Types of PE and KE
Oct. 16 Day 43
Bell Ringer
60sec
State the Law of Conservation
Energy can’t be created nor destroyed only
transformed (changed) or transferred(moved)!
(Note 1st and 6th need last 2 of KE type’s notes from PP)
*Staple Targets (red sheet) into notebook!
T-2 I can describe the 3 ways
energy transfers(moves).
Agenda:
1. Law of Conservation
2. Three ways energy transfers
“Popcycle” – energy cycle activity
Oct. 17 Day 44
Bell Ringer
1. What is
60sec
Temperature?
The Average Kinetic Energy in a
substance.
Faster KE molecules= hotter temp.
2. What is heat (Thermal Energy)?
Its a type of energy that can only be
detected if it is different.
Heat flows from hot
colder.
3. What do we use to detect the
average KE?
Energy Target 3
Thermometer –is a tool!
I can plan and conduct an investigation that provides evidence
that thermal energy transfer moves toward equal.
Agenda: Ice cream lab

Explain how the results of the Ice Cream lab’s
temperature (Average KE) support the
“Law of Conservation”.
Energy out of milk was ___degrees
Energy into the big bags rock salt and ice
was____ degrees. (See graphs on board)
They should be the same amount.
Why not exactly the same exchange?
Why not the exact same mass before and after?
I can describe energy
transformations and the transfer
between them.

T-5 I can make a model to show energy transformation
and transfer through a system.
Agenda:
1. Make a poster and label the transformation and transfer
through a system.
Tape up where you see your special #

Transfers by conduction
To do what:
Potato
It is the PE to boost the electrons
(It’s the 1.5volt battery)
Repeat at least 2 more times!!

T-5 I can make a model to show energy transformation
and transfer through a system.
Agenda:
1. Make FINAL COPY of poster and label the transformation
and transfer through a system.
2. Use “Energy Poster Viewing Evaluation”
form to evaluate yours.
3. We will walk around and look for 15 sec on each.
4. You can choose 2 or 3 others to evaluate.
****Only 2 people allowed at a station at a time!!
Energy Unit- T-3
I can calculate PE and KE for total energy.
Was all of the energy conserved?
Prove it!
Calculate each!
PE=mgh
KE=.5 mv2
Agenda: 1. Copy the Law
Law of conservation- says
Energy can’t be created nor destroyed only
transformed (changed) or transferred(moved)!
2. Compare the PE and KE of your egg and use
the Law of conservation to explain the results!
Calculate the PE of your egg:
PE= mass gravity height
PE = ___kg 9.8 m/s2 20 M
PE= _____ NM
PE = _____ Joule
KE = .5 (mass x Velocity2)
KE = ___kg __ m/s
KE= _____ NM
KE = _____ Joule

p
Law of conservation: PE + KE = Total Energy
Subtract the PE- KE = ________
You have to account for where the energy
went!
List all possibilities:
 _______________________
 _______________________
 ________________________
The biggest waste of
energy is in the form of
heat due to friction!!
Keep this in mind as you start designing your mouse trap car.
Remember to get 2 smooth pens& eye hooks.
