Do Now Draw a roller coaster Label where potential and kinetic energy are highest. Label where work has to occur

Welcome Back!! New Seats!! Assigned---- You are expected to be seated in your assigned seat, notebook opened and working on the due now when attendance is being taken

Expectations Group assignments Assign a person from your table to be the: -Team Leader-Materials Spec. -Recorder-Speaker/Q’s Model Groups: What lab looks like

Expectations Makeup work-In folder Retakes- Upon appointment, must have all homework in to be able to retake an assessment.

Expectations Bathroom Policy-One pass per week Materials-Do you have your notebook/pencil? 1 st time forgetting borrow from teacher/neighbor 2 nd time-conference with Mr. LePera 3 rd time- Call home

Disruptive Behavior Acting in a manner that is hindering the learning environment for others. Sequence of Consequences!!

Sequence of Consequences 1 st -Verbal Warning 2 nd - Asked to move out of group into a group of one. 3 rd -Asked to leave the classroom and go to another class to work and refocus- Student/Teacher conference 4 th - Referral w/call home-removal to dean

Technology Expectations No CELL PHONES!! No Electronics!! I will ask you to hand the device over and you can pick it up in the office after school….If it continues, I will have them call your parents to come and retrieve!!

Leaving class Your area must be picked up and you are only excused when I say you can leave

Goals What are you hoping to learn from this class this semester? What are you still having problems with? What can Mr. LePera do to make your semester a productive one?

Chapter 3, Section 2 Newton’s 1 st Law of Motion: Life and Death before and after Seat Belts

Do Now: Describe why different objects have different inertia? Use Newton’s 1 st Law to describe why using a seatbelt is necessary for safety in riding in cars.

Current Event Read the current event. Answer all questions on a separate sheet of paper. You have 30 minutes to complete

Agenda:  Do Now  Physics Talk

Physics Talk- Read the whole physics talk Use 2-column notes to organize and take notes on the physics talk

How do to 2 column notes Question Word Main Idea Answer Definition Details

Pressure! What is pressure? How do you calculate pressure? Force per area, where force is perpendicular to the surface. P=F/A P=pressure (pascal) F=Force (Newtons) A=Area (m 2 )

PTG Review Groups select problems

Essential Questions Use Newton’s 1 st law to explain why a passenger keeps moving when a vehicle suddenly stops. What evidence do you have from your experiments that collisions at higher speeds will have greater effect on the passenger? How does what you learned in this section help you design a safety device for a collision even though you don’t know the exact circumstances of the collision?
