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
Web Resource- www.learningcircuits.co.ukWeb Resource- www.learningcircuits.co.uk
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 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?
Use the Filamentality Web Page hyperlinks to find the answers to the following Scavenger Hunt questions.
