The Power of Healthy and Energy-Smart Choices
• Save Energy “act
local – Think
Global”
• Exercise – Biking is
a great way to stay
fit. Ride safely!
• Eat Healthy –
Making healthy
smart smoothies is
a great Start!!
Concept 1:
What Is Energy
FORMS OF ENERGY
All forms of energy fall under two
categories
KINETIC:
Kinetic energy is
energy in motion
POTENTIAL:
Potential energy is
stored energy
NGSS:
•
Construct, use, and present
arguments to support the
 RADIANT ENERGY
claim that when the kinetic
 THERMAL ENERGY
energy of an object changes,
 SOUND
energy is transferred to or
 MOTION
from the object.
 ELECTRICAL
ENERGY
 CHEMICAL
ENERGY
 NUCLEAR
ENERGY
 STORED
MECHANICAL
ENERGY
 GRAVITATIONAL
ENERGY
Concept 2:
Energy
Transformation &
Flow
•
NGSS
Construct a scientific explanation
based on evidence for the role of
photosynthesis in the cycling of matter
and flow of energy into and out of
organisms.
Plan an investigation to determine the
relationships among the energy
transferred, type of matter, mass, and
the change in the average kinetic
energy of the particles as measured by
the temperature of the sample.
.
The Law of the Conservation of Energy:
“Energy cannot be created or destroyed
it can only change form” (Einstein).
The question is….
Where did
the energy to
run the
blender or
light bulb
originate???

Healthy Choice 4-H
Energy Bike Reservation
Instructions:
To assemble the 4-H
energy Bike:
•
• To reserve the Energy bike – us the
on-line reservation site: WWW..
There are five locations (host
counties) in NYS
• Complete the registration/request
and make arrangements with one of
the host counties to transport the
bike lab to your location and back to
the host county.

4-H kid-size 20” bike
One tool kit box including: (screwdriver set; metric
and standard Allen wrenches; electrical tape;
adjustable wrench; side cutter pliers.

Identify the four (4) major components.
1. Energy bike
2. Bike trainer stand with the…..
3. ……Generator assembly (number 2. and 3. stay
connected as a single unit during transport)
4. Table-top display unit
Pull the “tightening handle” on the trainer to the
“open” position
Place the bike on the stand so the axels will be evenly
inserted to the trainer stand clamps
Tighten the trainer clamps to the bike axel by rotating
the tightening handle clock-wise.
Be sure the rear bicycle wheel is touching the trainer
“resistance drum” with moderate friction. To do this
reach under the generator and pull up until the rear
bike wheel rests snugly on the resistance drum. Then
tighten the “J” bolt with the large nut. This can
generally be done by hand (without a wrench).
The rear wheel should line up so that it is centered over
the resistance drum.
There are adjustment options if this is necessary. The
generator is attached to an assembly that may be
lowered up or down by loosening two nuts/bolts
Operating the 4-H energy Bike:
Safety Factors:
• Be sure participants have parental permission (this
may not always be possible depending on the kind of
event, but is suggested if a parent is present)
• Be watchful of clothing that could easily get caught in
the bike chain or spinning wheel
• Never let youth operate the bike barefoot
• Avoid letting children to young/too small operate the
bike. It is easy to slip off the pedals and “crash” on
the bike frame – Prevent Avoidable Injuries!!
Leading a fun and Educational Experience:
• Be sure participants have parental permission (this
may not always be possible depending on the kind of
event, but is suggested if a parent is present)
• Be watchful of clothing that could easily get caught in
the bike chain or spinning wheel
• Never let youth operate the bike barefoot
• Avoid letting children to young/too small operate the
bike. It is easy to slip off the pedals and “crash” on
the bike frame – Prevent Avoidable Injuries!!
Share the Healthy Choice Concepts and EnergySmart ideas:
• Choose one youth participant to pedal the bike
• Remember – those not on the bike are an
important part of your audience. Focus the
discussion on them as well as the rider
• Engage the audience in two (2) energy
discussions.
1. Source of Renewable Energy – use the guide
from pages 2 and 3 (“Forms of Energy” and
“Energy Transformation Flow”)to discuss
where almost all energy originates.
Depending on time you can also discuss the
forms of energy and definition of
“renewable” and “non-renewable” energy.
2. “Feel The Power” – let participants
experience the “feel” of generating efficient
and non-efficient light bulbs. They can also
power the 12 volt blender by peddling.
There is a round knob that allows you to
select the various bulbs and blender. Each is
labeled.
