Announcements

Please turn in your “Heal the Bay” permission

slip

You are expected to return to DVD on the bus

Your HTB materials will be used in your projects;

therefore missing the field trip will result in poor

grades on your projects and in class

Homework Quiz – Conservation of Energy

Two forms

Calculators (NOT PHONES) are allowed

Advanced Question has multiplication, algebra,

and exponents

Leave answer with square root if you don’t have a

calculator

U1D6 quizzes will be returned during this time

Reflect on M/T’s HW Quiz

Based on your score, does this change any of

your numbers in your learning log (1/29 or 30)?

Review Today’s Homework Quiz What is the definition of “Conservation of

Energy”?

What is the equation for “Conservation of Energy”?

Review Today’s Homework Quiz Which position has:

The most KE? The most PE? Approximately equal amounts of KE & PE?

Review Today’s Homework Quiz If position #1 had 14J of potential energy…

How much KE & PE would the other positions probably have?

PE = KE =

PE = KE = PE =

KE =

PE = KE =

PE = KE =

Review Today’s Quiz A cow is at rest at 6m high and then is

dropped. What is its velocity when it is still 3m above the ground?

6 meters

3 meters

Brainstorming Based on the materials you have or will have in

the future Brainstorm 12 different steps:

Must have different causes and effects! Brainstorm 3 simple “Final Tasks” related to your topic

Recall Specifications Only Step 1 has human interaction One object rises to max of 2 feet A different object falls to min of 0 feet 8 Steps minimum. A step: Cause Effect 30 seconds to 5 minutes
