Summary: The Physics Unit will take approximately 4 weeks (1 week per subsection below). Students will have hands-on experiences with basic concepts of physics, such as motion, force, work, energy and machines.

Subsections:

Forces And Motion (Motion, Force Changes Motion, Gravity) and Changing Motion (Forces Affects Motion, Forces Affect Acceleration, Friction Affects Motion)

Work And Energy (Work, Forms Of Energy, Energy Changes)

Simple Machines (Levers, Load and Forces, Wheels and Axles, Pulleys, Inclined Plane)

Lasting Ideas & Results:

Physics is the foundation of all the sciences, and students need to understand the basics in order to understand the world. An object's motion can be described by tracking and measuring its position over time, and these positions/motions can change by pushing or pulling. Many forces act on motion, and work is done when a force is used to move an object. Energy is the ability to do work. Learning these concepts is essential to understanding how things work and move.


 

Essential Question(s):

Why do things move? How can you tell if something has moved? What is gravity? What is speed and how is it different from velocity? How can a force affect motion? How are energy and work are related? How many forms of energy are there? What type of energy does the sun produce? How is energy transformed? Why do sidewalk curbs have ramps? How is a simple machine different from other machines? What simple machine would help you move a heavy load? Which would be easier, walking up a gradual ramp or a steep ramp? Why?

Desired Learner Outcomes: Enter the skills and knowledge students will acquire through the learning activities in this lesson.

Students will be able to...
Students will know...
Explain how motion, speed/velocity, and acceleration are related
Summarize the forces that act on a moving object; gravity, friction
Demonstrate a basic understanding of how forces affect motion
Explain how friction affects motion
Define work and energy
Compare and contrast potential and kinetic energy
Identify different forms of energy and give examples of each
Identify different kinds of simple machines and their uses
Explain how simple machines work together to make compound machines
Motion occurs when an object changes position. Speed is how fast it is moving, while velocity describes its speed and direction. acceleration is a change in speed or direction. Many forces, such as gravity and friction, act on moving objects.
Unbalanced forces change the speed or direction of an object.
Friction works against motion.
Work is done when a force is used to move an object a certain distance and energy is the ability to do work. Potential energy is stored, while kinetic energy is the energy of motion.
Chemical energy, electrical energy, light energy, mechanical energy, thermal energy and nuclear energy are different forms of energy.
Simple machines make it easier to do a task. Levers, wheels and axles, inclined plans, wedges and screws are the six kind of machines, and they each have different uses.
Two or more simple machines form a compound machine, like a bicycle.

Pre-Requisite Knowledge & Skills:
Students will have varied background knowledge of this unit, and don't require any specialized prerequisite knowledge or skills. Ability to use a ruler and a calculator would be greatly beneficial, but can be re-modeled and practiced throughout the unit. Students have previous exposure to this unit, so I hope to build on their prior knowledge.

Procedures:

Daily Procedure/Routine When students enter the classroom, they will immediately take out the previous night's homework for me to check, copy down tonight's homework, take out the question of the day sheet, and work on the question of the day while I check them in. We will then go over the question of the day (QOTD) and the previous night's homework. Another daily procedure in the classroom is that students are chosen randomly using popsicle sticks with their names on them to read or help with a lesson.

Day 1
Do Now: QOTD (on white boards): Why do things move?

To activate prior knowledge of unit, ask students to answer the following questions in small self-selected groups: What causes things to move? How is work related to energy? What are simple machines, and why would you use them? Share out responses before beginning study of unit. Next, read and discuss pages 484-485 in textbook. Create vocabulary guide for chapter. Then, do quick lab of students measuring a 10-meter distance in the hallway, then timing and running that distance. Return to classroom and model and practice the calculation of speed in meters per second. (Daily Assessment: teacher observation)

Day 2

Copy homework (WB 224) Do Now: Buckle Down Activity 1.

Review Do Now. Watch "Forces and Motion" and "Inertia" Study Jams. Read and discuss pages 486-488 in textbook and continue vocabulary guide for force, acceleration, inertia, friction and gravity. Model drawing force diagrams to show all the forces acting on an object. Have students draw a picture of themselves sitting in their chair as a force diagram (force of their weight pushing down and the force of gravity pushing up). Next, complete Inertia and Friction Lab by providing each student with a marble, a cup, and the Inertia and Friction Lab inquiry sheet. (Daily Assessment: teacher observation and lab sheet)

Day 3

Copy Homework (WB 225-226). QOTD (on white boards): Where will you run the fastest, on concrete or on sand? Why?

Modifications: small group and individual support during labs, grouping students both heterogeneously and homogeneously depending on the activity, extension activities provided where appropriate

Reflection:

Day 5 pushed to Day 6, and Day 5 changed to assessment, force diagrams and extension. The Roller Coaster Webquest took longer than expected, so it was extended 1 day. I also added some additional lesson review to make sure students understand kinetic and potential energy. I have made notes in my plans above showing the changes. Also, when I started teaching the forms of energy, I wanted to provide students with additional information sources to help them understand (at a basic level) the different forms of energy. I was afraid the PowerPoint made things too simple and didn't give enough detail. So, I found web sites with audio and visual information about each form of energy to show on the projector and provided students a list of sites (on a printed label) to visit at home or when we go to the computer lab. Also, with the extension of the lesson, a third day was added to make sure students had a better grasp on the different forms of energy and their transformation.

This week, students finished making up the Forces and Motions Quiz. Several students need help understanding these concepts, so I will add additional opportunities for review and reteaching the following week and push back our study of simple machines.
