A.1. Knows High Expectations Snow Day Materials: pencils and paper
Purpose: To allow students to continue learning from the home via technology. Instructions: completed assignments and questions to from 8-11 AM and 12-3 PM on snow days. 1. Read and interact with the slide presentation. 2. Complete the bell ringer and exit question by providing the gradecam number/letter choice (1. A, 2. B) the same as in class. 3. Answer the formative assessment questions. Example: Lab 1. The candle consumes O2. Energy conversion 1. PE stands for potential energy. 2. KE stands for kinetic energy.

No Pass A.1. Knows High Expectations Purpose & Life Connection Materials: pencils and paper Purpose: To solve equations that equate initial energy to final energy. Hook: A pole-vaulter converts kinetic energy into potential energy in order to propel themselves high into the air. At no time did the pole-vaulter’s mechanical energy ever increase. However, the potential and kinetic energy levels were constantly changing.

Conservation of Mechanical Energy (KE + PE) beginning = (KE + PE) end
Pass B.5. Higher Order Thinking DI: Energy Conversion Calculations No Electronic Devices Mechanical energy is the total kinetic and potential energy of an object. ME = KE + PE *Friction is ignored Conservation of Mechanical Energy (KE + PE) beginning = (KE + PE) end Calculating Kinetic Energy; KE = 1/2mv2 (m = mass, v = velocity), final answer is in joules (J) Calculating Potential Energy: PE = mgh (m = mass, g = gravity (9.8 m/s2), h = height), final answer is in joules (J) Three step method to solve problems dealing with conservation of energy. Read and understand (what information are you given?) Plan and solve (What formulas contain given values?) Look back and check (Is your answer reasonable?)

Assessment: Formative
Pass B.5. Higher Order Thinking DI: Energy Conversion Calculations No Electronic Devices Assessment: Formative (1-knowledge, 2-Skill) What is the first step to solving a problem dealing with conservation of mechanical energy? A 1.0 kg brick is dropped from rest and hits the ground at a speed of 5.0 m/s. Ignoring air resistance, calculate the gravitational potential energy of the brick before it was dropped.

As the pendulum swings downward PE is converted into KE
No Pass B.5. Higher Order Thinking DI: Gravitational Potential Energy No Electronic Devices The gravitational potential energy of an object is converted to the kinetic energy of motion as the object falls. Kinetic and potential energy undergo constant conversion as a pendulum swings. At the highest point in its swing the pendulum has its greatest PE at near the lowest point the greatest KE. As the pendulum swings downward PE is converted into KE As the pendulum swing upward KE is converted into PE as the height increases

E.1. Individual Progress/Learning Exit Question/Formative
No Pass E.1. Individual Progress/Learning Exit Question/Formative 4. At what point does a pole-vaulter have the most gravitational potential energy? At the bottom of the arc. The top point of the arc where they are at the highest point off the ground. The middle point because they have an equal amount of height and speed. After they clear the bar and begin to travel downward.
