NEW Behavior Log is filled out for 10/10/16 Copied Objective, HW into assignment list WARM-UP: 1.A carpenter hits a nail with a hammer. Compared to the force the hammer exerts on the nail, the force the nail exerts on the hammer during contact is:      a. less      b. greater      c. the same HINT: See Newton’s 3rd Law 2. What are some ways in which you could travel home from here? How would you describe these routes?

Mantra - Your Turn! Today is a great day for science because: Science is power. We are powerful because: We always make a difference.

Goals * State the Objective(s)/Standard (s)- RI 7.3; W2; Sci 2f * State the Purpose (Big Idea) -SWBAT explain how objects move by using multiple descriptors (speed, velocity, acceleration) and apply kinematic problem solving skills to solve problems in real life situations as told in a pick-your-path-story. SWBAT Compare/Contrast and Apply techniques to measure distance and displacement while analyzing how individuals, events, and ideas interact in real life situations as told in a pick-your-path-story.

Agenda I Do: Vocabulary/ Sample Problems We Do: Frayer Models You Do: Checkpoint Problems, Story Reading Summary/ Feedback/ Questions

Vectors A geometric object (line) that has magnitude (size or length) and direction They can be added to other vectors (tail to arrow tip) For example, we will draw forces as arrows (vectors)

Kinetic Motion Focus on 3 descriptions: Distance (d) Displacement (x) Speed (s) Velocity (v) Acceleration (a)

Distance and Displacement Distance (d): total space traveled Displacement (∆x): How far you have moved from the starting position A cool story about ants…

Link to time and speed

Guided and Independent Practice: Understanding Distance and displacement with graphs and practice problems from work packet Steps to solve: Distance: Add all chunks of movement together Displacement: Final placement – Initial placement

Example 1: Word Problem If we were to travel from Greenwood to Cleveland, what would be our distance and estimated displacement? Greenwood, MS Head south on Main St toward E Henry St for 0.8 mi Turn right to merge onto US-49E N/US-82 W, travel 4.5 mi Turn right onto US-49E N. Travel 15.5 mi Turn left onto MS-8 W. Travel23.9 mi Turn left onto Cotton Row. Travel 0.2 mi Turn right onto S Court St. Travel 0.1 mi Cleveland, MS

Example 2: Graphing distance vs. time! Miss K leaves the house and goes 2 miles in 4.5 minutes She gets stuck in standstill traffic for 1.5 minutes She forgets something and turns around. Takes 2 minutes to get back to the house. She stays for 2 minutes in the house looking for lost item. She heads back out on road, travels 4 miles in 8 minutes

Using slope for speed/velocity

Solving a graph problem:

Example 3: Your turn! Times at rest: Times moving forward: Final displacement:

Story Check-In: So far, what outside ideas, events, and students have shaped the context of the story?

Balloon-Powered Car Challenge! Create a balloon (air) powered race car for maximum speed and distance, and to demonstrate Newton’s Laws of motion. We will test and race them, measure distance, speed, velocity, and acceleration for PRIZES! You can build the cars out of any material, such as tissue roll, match box, spaghetti box, paper etc.

Questions to think/write about... Create and describe a plan to test changes in distance by using a balloon-powered car Basketball Team Challenge: How could you calculate your total displacement running during a basketball game?

Last Items/ Questions HW: Make your balloon car by Wednesday! Leftover Checkpoint Problems? Think about your progress and effort in Units 1 & 2 for Reflection/Celebration once grades are back Need Physics help or want to talk about your grades? Office Hours Saturday, 12-1 at T.B.A.

Connections Friday Volunteers Look around the house or try to think of objects that use simple machines OR Explain how a sport you love may need to use physics to explain how it works

GO GO FEEDBACK FRONTIER! Miss K – In my baggie (Comments on my teaching, living up to my goals, and any personal things you need to privately tell me) Your peers – Feedback to 1 or 2 people… What is something you saw him/her do that matched up with our class values? Why was it really great to see this?
