Energy Unit 2022

After introducing ourselves, we learned a bit about how the universe is put together from this PREZI

go ahead and match the symbols to the terms

This next video is of the Tacoma Narrows Bridge collapse - and why we should learn physics!

Share a thought or two you had while watching this video

The video below shows what we know about our universe...so far...

over 4 million galaxies have been imaged so far...

Big Bounce, Big Bang,

Please share a thought or two that you had about this video

You're probably starting to get a good idea about what Physics is about (everything!) - and this video might give you some more ideas :-)

After watching this video, please share some thing(s) you are interested in learning more about. Feel free to get creative!

Energy is what makes the universe go - and it seems to be involved with CHANGE. Take a field trip around the room and describe what kind of changes you see at each station (draw, sketch, take a picture, write a description, etc. for each station's things)

How do we know if an object has energy? (where did we observe energy (changes) from the previous question)

Now that you've discussed with your classmates potential similarities and categories of changes and aspects of energy, would you agree with the following model of the 123s of ENERGY? Write down, in your own words that help you understand them, the definitions of each storage mode.

Please include a visual example (pic/vid/sketch) from your stations (or elsewhere) of KINETIC energy storage (and add in a quick description)

Please include a visual example (pic/vid/sketch) from your stations (or elsewhere) of GRAVITATIONAL energy storage (and add in a quick description)

Please include a visual example (pic/vid/sketch) from your stations (or elsewhere) of ELASTIC energy storage (and add in a quick description)

Please include a visual example (pic/vid/sketch) from your stations (or elsewhere) of CHEMICAL energy storage (and add in a quick description)

Please include a visual example (pic/vid/sketch) from your stations (or elsewhere) of INTERNAL / DISSIPATED / Thermal energy storage (and add in a quick description)

Check out this simulation of a skate park.

• Play with the intro part first.

• Click and drag the skater onto the ramp.

• Select the options for pie charts and bar graphs.

• Watch how the energy storage methods increase and decrease as the skater moves.

• Answer the question(s) below.

1) What is happening to the total energy throughhout the skaters motion? (How do you know?)

From the simulation above:

Take a screen shot or draw your own representation showing when the skater has the highest gravitational energy.

Explain why they have the most gravitational energy at that point.

From the simulation above:

Take a screen shot or draw your own representation showing when the skater has the highest kinetic energy. Explain why they have the most kinetic energy at that point.

But what about FRICTION?

• Now click on the middle box that says friction.

• Turn on the pie charts and bar graphs options.

• Place the skater at the top of the ramp and release.

• Answer the questions that follow:

1. Take a screen shot or create your own representation of the energy storage at the beginning, middle, and end.

2. What is happening to where the energy is stored over time?

3. What is happening with the total amount of energy over time?

4. If energy is "going" to thermal storage, does the total still remain the same?

Now click on the playground and get creative!!

Answer the question below.

1. Take a screen shot of your cool creation

2. Take a pic or create your own representation of when your skater has the most kinetic energy, the most gravitational energy, and the most thermal energy.

3. Explain why they have the most of those storage methods at each of those spots.

Pre-tests 😄

We went over the Plan for Success -

PFS AP/Honors Physics

PFS Physics

Please grab, take home, complete, and bring back the sign off forms of the PFS.

Please mark below when you have completed the sign off form, Mr Dunklee will give you full credit when he double-checks your form (and he may try to give you an answer to your question(s)!)

The first six slides of this presentation were interesting,

we chatted a bit, rubbed our hands together and then warmed up our cheeks to explore working, heating, and radiating!

The three ways of moving energy around are Working, Heating, and Radiating...

As it turns out, anything with a temperature above zero Kelvin (absolute zero) gives off radiation, also called blackbody radiation. This may seem weird at first, especially since we only can "see" a small part of this radiation - the visible spectrum, but there is a lot more than meets the eye...

Watch this video...

...and share a thought you had about radiation that we cannot see below...

Netflix has a new documentary about seeing in color, and how different animals see things differently.

Let's do a quick check of our understanding about ways to transfer energy around....

Add in a picture or video of working transfer of energy and explain why that is working transfer

Add in a picture or video of heating transfer of energy and explain why that is heating transfer

Add in a picture or video of radiating transfer of energy and explain why that is radiating transfer

Explain what happens to energy when there is friction involved... does it get used up, or just go somewhere else? Play around with the FLIR cameras or watch the below video if you don't have FLIR cameras
