Electricity!

9

### Unit S.M.A.R.T. Goal:

Students will attain an 80% passage rate in 3 of 4 trials

### Objective:

Introduce students to the concept of Electricity.

### Life Connection:

Students will answer this question before leaving class today.

### Behavioral Norms:

• Learn from mistakes
• Tolerance
• Participate
• Personal electronics only when appropriate

### Key Concepts:

• Energy in Chemical Processes
• Wave properties
• Information Technologies and Instrumentation Practices

### Warm Up: (5 minutes)

How much wood would a woodchuck chuck if a woodchuck could chuck wood? (Yep, There IS an answer!)

No one figured it out on Tuesday. I am curious to see if anyone figured it out yet!

### Task #1  – Last Lab

Make your own batteries lab! We will be following the directions in the lab guide to do this one. You will be choosing your own groups.

CH 9 Review material

Chapter 9 Exam – 20 questions

Time depending we will look at our last unit today. Start brainstorming about creating a device run by an electric motor. This is one of the performance tasks for Physical Science B Unit 10.

1. Execute the intended goal.
2. Have an attractive design/presentation.
3. Include at least one working electric motor.
4. Have at least one additional input/output such as a microphone, speaker and/or LED light.

Materials:

1. One small electric motor
2. Two alligator clips attached to coated copper wires
3. One D-Cell battery

Crafting Materials:

You may use what is available at the center and/or what you can find in your house.

### Next Generation Science Standards:

HS PS  2-5 Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.

HS PS 3-1 Create a computational model to calculate the change in the energy  of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

HS – PS 3-5 Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
