THERMAL ENERGY

TUESDAY, 1.22.2019 1. Please find your assigned seat quickly and quietly. 2. Fill in your agenda for the week. 3. Today’s plan: • Review agenda • Quiz Retake • Thermal Energy Pre-test

WEDNESDAY, 1.23.2019 1. Pick up a “Focused Notes Template” from the counter. 2. Self-Starter #4 • 4.1) How do you know what you should do when you come to class each day? • 4.2) If you are in this ______________, you are in _______________. • 4.3) In order to be “on time” to class, where should you be when the bell rings? 3. Today’s plan: • Self-Starter • High School 101 • Focused notes overview. • Thermal energy transfer.

HIGH SCHOOL 101 • We will occasionally discuss and practice techniques to help you succeed in high school. • Today’s HS101 topic is: Note -taking • We will try a few different versions of notes so you can decide which one works the best for you.

FOCUSED NOTES • We will use this template for a little while before exploring some other techniques. • This technique was developed by Cornell University and is used at Meridian High and all AVID schools. Theme of lecture/section. Could also be an essential Q. Main ideas you Detailed info to support main ideas. This could learn or be definitions, sketches, examples, etc. discover.

Main ideas! HOW HEAT MOVES Topic! • Heat • The energy in a substance that can be transferred. • Conduction • Direct Contact • Convection • Transferred within liquid (air counts) • Radiation • Transferred through “waves” • NO physical contact between objects. • Works in a vacuum.

WHAT IS HEAT? Main idea Supporting information • Heat • Thermal energy of an object that is transferred to something cooler. • Energy ALWAYS moves from high to low!

Main idea CONDUCTION Supporting information • Conduction • Transfer of heat through direct contact. • Effected by: • Temperature difference • Conductivity (How fast something moves energy)

Main idea CONVECTION Supporting information • Convection • Transferred through a fluid (including air!) • Energy moves from one particle to another in the fluid.

Main idea RADIATION Supporting information • Radiation • Transferred through “waves” • NO physical contact between objects. • Works in a vacuum.

POLAR BEAR PROJECT • Our cub has lost it’s mother! • In the wild, babies often stay put until mother finds them. • Design and build a shelter to keep our cub warm until momma bear find it. • Project: • Get with your group of 4-ish. • Brainstorm things you could use to insulate your cub’s mini-shelter.

THURSDAY, 1.24.2019 • Self-Starter #5: List the type of heat transfers shown in the picture below. 5.1 5.2 5.3

POLAR BEAR PROJECT • Our cub has lost it’s mother! • In the wild, babies often stay put until mother finds them. • Design and build a shelter to keep our cub warm until momma bear find it.

PRE-LAB • Complete the pre-lab with your group of 4-ish. • Use your notes from yesterday to review heat transfer. • Brainstorm materials to use and how they will insulate the cub. • When it is complete, come see me to get your container.

FRIDAY, 1.25.2019 • Get together with your Polar Bear Cub Club and get your mini-shelter ready. • You will need to be able to put the bear and thermometer in and close the lid 5 minutes after the bell rings.

FRIDAY, 1.25.2019 • Today’s Plan: • Get mini shelters ready. • Set them outside and monitor temperatures. • Review basic heat transfer concepts (update notes). • Prep for Monday absence. • Clean up.

TEMP MONITORING • Grab a Polar Bear Lab Summary worksheet. • Record the temp for the control and your cub in the 0 minutes column. • Record the temperature values every two minutes
