1) Using a wire, a battery and a bulb, what does it require to light the bulb? What is the role of the battery, the bulb and the wire?

1) It requires a complete loop (circuit from one end of an energy source (battery) through an energy receiver (bulb) and return to the other end of the battery to light the bulb. The wire (energy conductor) is the pathway for the energy to flow between the energy source and the energy receiver.

WATT’S MY WORD? Battery the energy source critical contact point –very important place to make contact/touch negative positive Bulb energy user – is evidence of a complete or open circuit

if it lights or does not light What are examples of energy users? Wire completes the pathway between the energy source and

the energy user –wires are metal (copper) Complete circuit a complete/closed loop from one end of the power

source (battery) through the (energy user) bulb and back to the other end of the battery. Evidence of a complete circuit is a lit bulb.

Open circuit a circuit that does not make a complete loop – in an

open circuit the bulb does not light Conductor material that allows the flow of electricity Examples: metals such as copper I nsulator material that does not allow the flow of electricity Examples: glass, plastic, wood Why are insulators important? INSIDE A BULB Support wire

Critical contact point

What is the role of the filament, glass bead, and support wires?

Engaging Scenario You and your friends are at Disneyland. You

decide to go on the Haunted Mansion ride. You get on the ride. The ride starts. Then all of a sudden the ride stops and everything goes pitch black except for the screams and howls inside the Haunted Mansion. Then a voice comes on the speaker. “Ladies and gentlemen, boys and girls this is the ride technician at Disneyland. I have some good news and bad news for you.”

“The good news is that power will be restored. The bad news is that it may not be until tomorrow and you will spend the night in the dark in the Haunted Mansion. There is a way to get out before tomorrow. If you reach into the front of your car you will find a ziplock bag. Inside the bag are a a wire, a battery and a bulb. There is a way to assemble them to make a light to find your way out before tomorrow morning.”

Engaging Scenario

The good news is you find some objects in your ziplock bag that may help you.

• A small bulb• Wire• A battery

You and your friends have a problem.

What is the problem here?

Focus Question

Criteria

• Is a simple question directly related to the scenario that can be investigated with results that can be communicated.

• Cannot be answered “yes” or “no”.

FOCUS QUESTION

With your group discuss a focus question related to the problem presented in the engaging scenario. Record it in your notebook. Be prepared to share with the class. You may wish to use the following sentence starter to help you:

How can we …. ?

1ST NOTEBOOK ENTRY

Focus Question(s)

How can we light the bulb using a battery, wire and bulb?

Prediction

• Write a prediction describing what you think will happen - an answer to the focus question.

• Conditional statements

If ………. then …….. will happen because…..or I think ……. will happen because ……

2ND NOTEBOOK ENTRY

Task

• Diagram at least two ways to light the bulb

• Diagram at least two ways the bulb did not light

• Accurately label your diagrams.

Things to consider

• How are you going to organize your diagrams? (data)

Data Organizer ?

DATAOrganizing and planning

Before you begin solving the problem, How will you organize your data? Discuss with your group the design of

the chart and record it in the notebook. You may not start testing your prediction until your chart is ready.

Making Meaning Conference

• Planned discussion that uses an organizer to make thinking visible.

Making Meaning Conference

• What patterns can we see from our data?

• What about the outliers?• What claims can we make?• What evidence do we have to

support our claims?• An oral rehearsal for writing

Making Meaning Conference

• Discussion Points – Guiding Questions.1. Using a wire, a battery and a bulb, what does

it require to light the bulb? What is the role of the battery, the bulb, and the wire? (What were you going to observe or measure)

2. What are the differences between a closed (a circuit that lights the bulb) and an open (a circuit that does not light the bulb) circuit? What is your evidence?

Examining Your Data

• Look at your diagrams showing when the bulb did not light– Where did the wire touch the bulb?– Where did the bulb touch the battery?

Examining Your Data

• What claims can you make about the ways the bulb did not light?

• What was your evidence?

I claim the bulb did not light because ……….

Examining Your Data

• Look at your diagrams showing when the bulb lit– Where did the wire touch the bulb?– Where did the bulb touch the battery?

Examining Your Data

• These places are called critical contact points

• Be sure to label the critical contact points on your diagrams

Examining Your Data

• What claims can you make about the ways the bulb lit?

CONCLUSIONCONCLUSION

Write a concluding sentence using one of the stems:

“Today I learned … .”

or

“In conclusion, … .”

LESSON CONTENT GOALS

Achieved Curriculum

• How do we know if the intended curriculum is met if effective feedback is not in place?

Feedback “Issues, Evidence, and You.” • For example:• What evidence do you have in your

data to support your claims?

• What claims can you make from your evidence?

• What is another explanation for what happened?
