Interactive notebook Find the next blank page in your notebook Label it: Energy 6.P.3.1: Add this to your table of contents

Today’s Objective…. To figure out how thermal energy is it transferred? To figure out how chemical energy can be released and transferred?

Write in notebook: Heat (Thermal Energy) Transfer Energy (heat) can be transferred from 1 system to another or from a system to the environment in different ways (radiation, conduction, convection)

Write / Draw in notebook Examples of Heat Transfer

Write in notebook Conduction Energy (heat) flows throughout materials or across space from HOT (WARMER) objects to COLD (COOLER) objects

Thermal Energy… Today we will review how Thermal (heat) energy can travel (3 main ways…) You will receive a graphic organizer to record this information You will write all the information from each slide onto your handout You will also draw a picture

Thermal Energy Write this: Heat energy due to the motion of all the particles in an object Heat

Conduction Box Write this: Heat traveling through solids when two things are touching Draw this: (example: pan on a stove burner; heat from the burner travels into the metal pan, causing the temperature of the pan to rise) Molecules or atoms collide to each other randomly and during this collision they transfer some part of their energy. With the same way, all energy transferred to the end of the object until it reaches thermal balance. As you can see from the picture, atoms at the bottom of the object first gain energy, their kinetic energies increase, they start to move and vibrate rapidly and collide other atoms and transfer heat. Conduction is commonly seen in solids and a little bit in liquids. In conduction, energy transfer is slow with respect to convection and radiation. Metals are good conductors of heat and electricity.

Radiation Box Write this: Heat moving across the space between two objects that are not touching Draw this: (If you hold your hand over a pan, near a hot plate or near an iron to see if it is hot)

Convection Box Write this: Heat traveling through liquids and gases in a circular pattern (convection currents) Draw this:

Remember…..write this on the bottom of your graphic organizer If 2 things are touching…. conduction If something heated is rising or circulating in liquids or gases….. convection If heat moves across spaces between 2 things that are not touching…. radiation

Now its your turn…. You will receive a pie chart handout We will go over the directions now…. Then I will pass out scissors and glue bottles Remember, if I see anyone putting glue on their hands, I will take up all the glue (you are wasting my classroom supplies) BEFORE YOU GLUE YOUR STATEMENTS DOWN, YOU MUST RAISE YOUR HAND FOR ME TO CHECK IT FIRST!!!!
