Lesson 6.2: Energy

SLIDESMANIA.COM

SWBAT: I can explain the law of
conservation of energy.

Vocabulary

Chemical energy: energy stored in the bonds of
chemical substances

Radiant energy: light energy

●8.P.2 Explain the environmental implications associated with the various methods of obtaining, managing and using
energy resources.

○8.P.2.1 Explain the environmental consequences of the various methods of obtaining, transforming, and distributing
energy.

○8.P.2.2 Explain the implications of the depletion of renewable and nonrenewable energy resources and the
importance of conservation.

CONSERVATION OF ENERGY:

ENERGY CAN NEITHER BE CREATED

NOR DESTROYED; BUT, IT MAY BE

TRANSFORMED

●

An energy transformation is the change
of energy from one form to another.
○Chemical: energy is stored in the bonds of a
chemical substance
■Energy is released when the bonds are
broken

■Glucose, fossil fuels, burning wood!

○

Mechanical

■Kinetic: energy due to an object in motion

■Potential: the energy held by an object
because of its position relative to other
objects

○Thermal: heat energy - sometimes the result
of inefficient energy transformations

○Electrical: the power an atom's charged
particles have to cause an action or move an
object

○Radiant: light energy (can be UV radiation
or solar energy)

ENERGY TRANSFORMATIONS

Multiple Choice

Batteries have _________ energy.

• mechanical

• thermal

• chemical

Multiple Choice

The sun gives off __________ energy.

• mechanical

• electrical

• radiant

TRANSFORMATIONS OF ENERGY EXAMPLE:
TURNING ON A LIGHT

Mechanical energy

Radiant energy
Thermal Energy

Radiant energy

Potential to kinetic energy

Electrical energy

Thermal energy

Loss of electrical energy

due to resistance

Multiple Choice

Energy transformations occur when...

• energy is created through conduction

• energy changes from one form to another

• two forces slide together that are touching

• a chemical reaction takes place

Types of energy sources used

to produce Electrical Energy

Solar

Nuclear

Wind

Hydroelectric

Geothermal

Tidal

Biomass

Fossil fuels

Types of energy sources used

to produce Electrical Energy

Nuclear

Wind

Hydroelectric

Geothermal

Tidal

Biomass

Fossil fuels

●Each of these
energy sources is
used to generate
mechanical
energy which
then spins a
turbine.

●That mechanical
energy is then
transformed into
electrical energy
by a generator!

Turbine: a device that harnesses the
kinetic energy of some fluid (water,
steam, air) and turns this into the
rotational motion of the device itself.

Breakout rooms

1. You may work independently or together and may switch rooms.

2. Failure to work effectively and be appropriate will result in your removal

from a group breakout room for the rest of the semester and parent

contact.

3. Go to Lesson 6.2 to get the link for the Formative - there is a how to video

within the assignment to help you out!

4. Go to Formative to access the PhET: Energy Forms and Changes Virtual Lab

5. Follow the directions to complete the assignment!

6. Raise your hand if you need help! :) Be patient!
