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.

NOTE-TAKING

NOTE-TAKING

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. Detailed info to support main ideas. This could be definitions, sketches, examples, etc. Main ideas you learn or discover.

HOW HEAT MOVES

• 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.

Main ideas! Topic!

WHAT IS HEAT?

• Heat
• Thermal energy of an object that is transferred to something cooler.
• Energy ALWAYS moves from high to low!

Main idea Supporting information

CONDUCTION

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

Main idea Supporting information

CONVECTION

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

Main idea Supporting information

RADIATION

• 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.

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.

• 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
