Bell Ringer 60sec

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 andKE

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 60sec

1. What is 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 averageKE? Thermometer –is a tool!

Energy Target 3

I can plan and conduct an investigation that provides evidence that thermal energy transfer moves toward equal.

Agenda: Ice cream lab

Bell Ringer 60sec

Oct 21, 2023

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.

Agenda

1. Ice cream analysis of Law of Conservation

2.Pop cycle transformation chart

3 Laws of Thermodynamics

T-1

I can describe the different forms of PE and KE.

Agenda

Practice identifying forma of energy transformations on smart board the in teams with puzzle pieces you put in order and them make an energy flow chart.

Bell Ringer 60sec

Label the energy transformations of

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 #

------

Name the type of systemYour Full Name #

“Potato Clock”Hour

(resource & page #)

1. Type of energy transformation

_____Chemical_PE__ Picture

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!!

Tape up where you see your special #!!!

Bell Ringer 60sec Just Breath!

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

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.

Coaster virtual lab

Bell Ringer 60sec Oct. 30

Thermal energy transfer fan, Diagram the energy transfers.

Agenda:

Energy Exam- take your time!

Turn over when done, I will collect.

Read Science World when done!

Bell Ringer 60sec Oct. 31

Diagram the energy transfer of a mousetrap car.

Practice for retest

Nov.1 Be Happy Luke’s 1st BD

How to retest:

1. Staple completed NOTES and Q&A’s

to the BACK of your test.

2. Turn in on tall desk.

3. Retest-Complete only the Targets

you did all the practice for to go for the 4.

4. Staple Retestto the BACK

Of your other papers on tall desk.

5. Put on“re-grade please”tray.

Bell Ringer 60sec Nov. 4

Calculate the PE energy of the rollercoaster on the board. PE = mass gravity height

PE= 25 kg 9.8 m/s2 4 Meters PE= ______Joules

What is the KE at the bottom of that first hill?

What is the PE and KE half way down the hill?

PE + KE = Total Energy

Law of conservation says:

Matter, energy and momentum Can NOT be created nor destroy only transfer or transform
