Warm-Up 1/6/15• Get our your INTERACTIVE

NOTEBOOK and your BLUE Fusion Textbook.

• Go to INB52 and write “Energy Vocab Lesson 1” as the title.

• Go to Lesson 1 – pages 100-108 – and copy down the vocabulary words and definitions on INB52.

• When you finish: Complete New Year Word Search from yesterday.

Energy Pre-Test• Answer EVERY question.• Write your name on the back of your

index card and place it in your folder.• When you finish:

• Go to INB51 and design your unit cover page. Write the word ENERGY in large, bold letters. Add color. Draw pictures about ENERGY. You may use your textbook to help you come up with ideas.

Wrap-up

• On INB52, focus on each vocabulary word. Rate it with stars according to the following:

• One star – never heard/seen the word, don’t know it at all

• Two stars – seen it/heard it but not sure what it means

• Three stars – know it and could explain to someone

ANSWERS

Energy!

What is Energy?INB53

• Stop and Jot. On the top of your notes write down: where have you heard the word energy before? What do you think it means?

Q1: What is Energy?

• Energy is anything that can cause matter to change.

• Hitting a baseball, holding a book above your head, digesting food and heating water all take energy!

Q1: What is Energy?

• Energy is anything that can cause matter to change.

• Hitting a baseball, holding a book above your head, digesting food and heating water all take energy!Q2: What text

features in our book can help us

learn about energy?

•Pictures – give examples of energy

•Captions – explain what is happening in the picture and connect it to the text

Q2: What text features in our book can help us learn

about energy?

• Pictures – give examples of energy

• Captions – explain what is happening in the picture and connect it to the text

Wrap-Up

• Draw a picture of a time that you used a LOT of energy!

Thursday Warm-up

•Explain the science behind this comic.

Ice is made when water

gets cool (frozen).

The ice cube is “cool”

Energy•There are two types of Energy:•Kinetic Energy•Potential Energy

Energy•In these two types, there are many different forms of energy:•Chemical, mechanical, sound, heat, light, electrical, nuclear, gravitational

Day 2: Potential and

Kinetic Energy

Potential and Kinetic EnergyINB55

Review: What is Energy?

•Anything that can cause a change in matter.

Two Types of Energy:

1) Kinetic Energy2) Potential Energy

Potential Energy1. Potential Energy is stored energy.2. An object with potential energy has the ability to move or change.

Potential Energy3. Potential energy depends on an object’s position or condition.Example:

Examples:

Kinetic Energy4. Kinetic Energy is the energy of movement.5. It depends on the mass and speed of a moving object.

Examples:

Potential or Kinetic?

• If you see POTENTIAL ENERGY, you should STAY ABSOLUTELY STILL AND SILENT!

• If you see KINETIC ENERGY, you should stand up and say “KINETIC ENERGY” one time!

Potential or Kinetic?

Potential or Kinetic?

Potential or Kinetic?

Potential or Kinetic?

Potential or Kinetic?

Potential or Kinetic?

• Types of Energy• Can transform into other types of energy

IMPROV!• With your table group, come up with a

body signal to represent KINETIC ENERGY and POTENTIAL ENERGY. (2 minutes)

• When I say KE, your group should perform your signal for Kinetic energy.

• When I say PE, your group should perform your signal for Potential energy.

Cut out and glue to p. 55

Thursday Wrap-Up

• Write ONE SENTENCE that describes a time you used POTENTIAL energy. (Get creative – there are so many different forms of energy!)

INB64 – Thermal Energy Notes

• Fold Notes page in half • Glue to iNB64

Thermal Energy Transfer

• Thermal energy transfer is heat moving from a warmer object to a cooler object.

Heat TransferConduction, Convection and Radiation

How is Heat Transferred?There are THREE ways heat can move.

– Conduction

– Convection

– Radiation

CONDUCTION• Heat is transferred from one particle of matter to

another in an object without the movement of the object.

• Conduction = CONTACT• (Requires direct contact between two

surfaces.)

Have you ever…• Touched a metal spoon sitting in a pan of

boiling water only to be surprised by HOW hot it is??

Think back to what you know about metals and nonmetals. What conducts heat better, metal or nonmetal? Why?

Example of Conduction – pot handle on stove

• Think of a metal spoon in a pot of water being heated.

• The fast-moving particles of the fire collide with the slow-moving particles of the cool pot.

• Because of these collisions, the slower particles move faster and heat is transferred.

• Then the particles of the pot collide with the particles in the water, which collide with the particles at one end of the spoon.

• As the particles move faster, the metal spoon gets hotter. This process of conduction is repeated all along the metal until the entire spoon is hot.

EXAMPLE OF CONDUCTION

• A piece of cheese melts as heat is transferred from the meat to the cheese (Contact)

CONVECTION• Convection is the movement that transfers heat

within fluids and air (gas)• Heat is transferred by currents within the fluid or gas

• Convection = VENTS (through air and liquid particles)

• Convection moves in a circular pattern

Examples of Convection:• Have you ever noticed that the air near the

ceiling is warmer than the air near the floor? Or that water in a pool is cooler at the deep end?

• Examples: air movement in a home, pot of heating water.

• Pick one of these examples and draw the circular pattern in your notes.

Explaining Convection

• Convection currents cause the cooler breezes you experience by a large body of water.

• These currents also cause the movement of magma within the earth.

RADIATION• Radiation is the transfer of energy by

electromagnetic waves• Radiation does NOT require matter to transfer

thermal energy• Radiation = Radiates (heat escaping the sun)

Radiation May Come From Other Sources

Have you ever sat too close to a campfire while cooking marshmallows? You’re enjoying the warmth ….. only to notice that your skin is really warm?

Examples of RADIATION

1. Fire2. Heat Lamps3. Sun

WednesdayWrap-Up

• Describe (in words or picture) a time you have observed one of these thermal energy transfers.
