Unit Topic or Theme: Science
Grade: 3
Lesson Topic or Theme: Types of energy
Lesson Objectives:
The student will be able to define the different types of energy sources which include tidal, wind, solar, geothermal and hydroelectric power.
The students will be able to classify the different forms of energy sources and will be able to compare and contrast how the different energy sources work for different environments.
The students will be able to apply their knowledge of the different energy sources to create an alternative power plant within the groups assigned.
Instructional Technique: Group work, Computer game, Presentations, worksheets, Video,
Instructional Materials: 2 worksheets, Video https://www.youtube.com/watch?v=av24fEMhDoU computer game https://wonderville.org/asset/save-the-world
Theoretical Perspective: To get a sense of how alternate energy sources can be used in the world depending on location
Procedure:
Introductory Activity
Step-by-step
Work individually on website and complete “Save the World!” worksheet given
Watch video: https://www.youtube.com/watch?v=av24fEMhDoU
Split up into groups and assign different regions (Canada, USA, Japan, India)
Complete worksheet assigned using one laptop per group
Check in with each group after they complete worksheet and have them begin creating their poster
Include on poster: names of group members, name of country, the questions from the worksheet, and a diagram of the energy source used in their country
Closure
Presentations of each region the following class
Adaptations for different learners
A written instruction
Provide examples
Say the instructions out loud
Step by step instructions
Homework
Finish presentations if needed
Evaluation: The teacher will evaluate the
students based off the presentation of their
group posters and the explanations that will
defend their alternative energy plant.

Name:
Save
the World! The
world is at risk and you must save it by
choosing the correct form of alternative
energy. Click on the play button to
start the game. Watch brief tutorial, then
press continue.
Drag each form of alternative energy to
where you think would be the most efficient
to make the generator reach at least 100%. Canada,
Tidal Energy Tides
and currents create mechanical energy.
Underwater turbines capture the mechanical
energy to generate
. Tidal
currents turn a power-generating .
mounted on the seabed. Groups of
underwater turbines are built in places
with strong currents. As the current
moves past the turbine, the water
pressure turns the . Inside
the turbine, the rotor blades connect to
the . Each
revolution of the rotor turns the gears.
The gearbox changes the turning force.
The turbine turns faster with .
force
in every revolution. When
the gears turn, they drive the
generator, creating . Electricity
is distributed through a .
on
the ocean. India,
Hydroelectric Hydroelectric
energy uses water trapped by dams and the
force of .
to create electrical power. Hydroelectric
power creates a constant source of
electricity- enough to power
.
of homes.
The
dam traps water. This area is called a .
Reservoir water flows through a tunnel
inside the dam into a . Inside
the powerhouse, the force of the water
in the tunnel turns a . The
turbine drives a ,
which creates electricity. Electricity
is carried to communities through lines
from the generator. Water
then flows out of the tunnel and return
to the . USA,
Solar Energy Solar
panels, also known as .
cells, are thin plates that transform
the Sun’s heat into electricity. Often,
they are made of small, .
cells.
Solar
cells have a positive side and a
negative side. When .
hits
the panel, it creates an electrical
field, just like a battery. The
cell absorbs photons from sunlight,
freeing electrons. The electrons move to
the
.
of the cell and through the connecting
wire.
4. Solar
panels are wired to a battery bank. .
electricity
is stored in the
battery bank.
Japan,
Geothermal Geothermal
energy uses the Earth’s to
create power. The Earth’s temperature
increases about one degree Celsius every meters
below the surface. This natural heat source
can be used for energy .
Holes
drilled in Earth’s “
“
let steam rise to the surface. As
the from
the heated water rises to the surface,
it powers a turbine. The
turbine powers a generator, which
creates to
power homes and businesses. Cool
water from the cooled steam is through
the system, creating more steam and
continuing the process.
