MST Inquiry UnitIntroduction

This is an MST inquiry unit model, for the lessons have a link between math, science and technology.

Incorporate Bloom’s taxonomy, Gardner’s multiple intelligences.

Adhere to the mandated mathematics, science, technology, and ELA standards.

It contains a Filamentality Web Page, and a MyEnectricalEnergywiki.

Introduction (Continued)

Lessons:

How electricity travels.

How energy can be transferred from one place to another

How interactions with forms of energy can be helpful or harmful.

Lesson 1- Types of Circuits

Collecting Their Data…

Supplies Used…

Did it work?

Why or Why Not?

How you Altered the Circuit…

Circuit 1 Battery, string, bulb

No Because I did not

Circuit 2

Circuit 3

You never knew circuits could be this fun!!!

Lesson 3- Static Energy

Students will complete an activity where they Students will complete an activity where they will test out different objects to see which will test out different objects to see which objects create staticobjects create static

Different materials they will use to test: Different materials they will use to test:

Balloon against person’s hair, paper, and Balloon against person’s hair, paper, and StyrofoamStyrofoam

Carpet/rug and piece of metal (ie. Door Carpet/rug and piece of metal (ie. Door knob)knob)

Now That’s Static!!

What are the uses of Electricity?

Home & School Uses of Electricity:

How to calculate Kilowatt-Hour Usage?

How much electricity we use in the classroom?

Electrical Devices

How many? Estimated Wattage

Computer 4 150 Watts

Fluorescent Lights

9 40 Watts

Compact Refrigerator

1 57 Watts

Some Electrical Devices in our Classroom:

Watts /1000 = (kW)Kilowatts (kW) x Hours of Use = kilowatt Hours (kWh)Kilowatts Hours (kWh) x $0.093(Rate) = Cost of Usage

What is a Kilowatt-Hour?How much coal is needed to

produce 1 kilowatt-Hour of electricity?

Answer: 1 pound of coal

Where do you think this energy is generated from?

What is the kilowatt-Hour usage for three electrical devices in my classroom?

kWh usage = 5.019

A classroom in the United State on average uses?

Answer: one Kilowatt-hour of electricity

What are non-renewable energy sources?

Non-renewable if they cannot be replenished (made again) in a short period of time.

What are renewable energy sources?

renewable energy sources such as solar and wind can be replenished naturally in a short period of time.

Energy Sources

Non-Renewable Sources Renewable sources

Oil

Coal

Gas

BiomassGeothermal

Hydropower Solar Wind

Are you a Energeneous?

Scavenger Hunt: Renewable & Non-

Renewable Energy Sources

 What are the five renewable energy sources?

 What are the uses of electricity?

 

How the electric energy used is measured?

 Why it is important to save (conserve) energy?

 How can you save energy?

 Where does electricity come from?
