The CASTLE™ Approach
CASTLE is a high school electricity
curriculum that leads students from initial

understanding of electrical phenomena. A
sequence of self-guided experiments uses
large capacitors and transient bulb lighting
to help students confront misconceptions,
grasp the physics of current propulsion and
build intuitive explanatory models.
Typical Experiments
Core Curriculum investigates:
1. What is happening in the wires?
2. What do the bulbs do to moving
charge?
3. Where does the moving charge
originate?
4. What makes charge move in a
circuit?
5. How do wires distribute electric
pressure in a circuit?
6. How are values of circuit variables
measured?
Advanced Curriculum investigates:
7. Does all matter contain charge?
What are electrons?
8. What is the cause of distant action
effects?
9. What pushes on tiny charge carriers
like electrons?
10. How do semiconductors work?
What is AC?
11. How do motors and generators
work?
12. How are magnetic and
electromagnetic fields produced?

Connection to
Galvanometer
Graph shows voltage drop across various lengths for
three different material wires. The slope of the line
(along with wire diameter and current) is used to
calculate the resistivity of the material.

1.3 mm diameter)
For the experiment shown, the GLX Power Amplifier produces a 10 second voltage ramp to apply a varying
current through a brass wire. The current is measured directly by the Power Amplifier, and the voltage drop
over the selected section of wire is measured by the Galvanometer Sensor. A graph of voltage drop vs. current
is created, and the slope of this line is the resistance of that length of wire. See pages 10-14 for more information
on the GLX and Power Amplifier.

cutting-edge energy technology.
Fan
Fuel Cell
SE-8573
Electrolyzer
Hydrogen
Storage Tank
Electricity from the solar panel is used in
the process of electrolysis to split water
into oxygen and hydrogen.
The hydrogen is used as fuel in the fuel cell.
The process that takes place in the fuel cell
is the opposite of electrolysis: the hydrogen
is combined with oxygen to make water
and produce electricity.
In this demonstration, the electricity
produced by the fuel cell is used to operate a fan. The fuel cell has an efficiency of
about 50%.
This apparatus uses Proton Exchange
Membrane (PEM) technology. A PEM is a
proton-conducting polymer membrane that
is covered with a layer of catalyst material
on both sides. These two layers form the
cell’s cathode and anode. One PEM is used
to separate the hydrogen from the water,
and a second PEM is used to re-combine
the hydrogen with oxygen to make water.

A The hydrogen and oxygen accumulate
Hyrunner Hydrogen Car
in their respective tanks. Since there
are two hydrogen atoms for each oxygen atom in a water molecule, twice
as much hydrogen gas is collected. The
hydrogen gas collection tank will fill
completely in about two minutes.
A Disconnect the power supply and the
Hyrunner is ready to hit the road!

The energy from a fuel cell can be used to
do work on any system. In the case of the
Hyrunner, the energy is used to move the
car across the floor at a maximum speed of
20 cm/s. The Hyrunner is well-constructed,

PASCO’s Hyrunner Hydrogen Car is an
outstanding example of a promising energy
source for the future. The hydrogen fuel cell
is an amazing device that combines hydrogen
with oxygen to produce water and energy.
Hydrogen fuel cells boast an efficiency that
is roughly twice that of internal combustion
engines.
The fuel cell contains
a Proton Exchange
Membrane which
facilitates energy
production.
with all components visible for student
inspection and a more thorough
understanding of its workings.
How it Works
A Place distilled water into the two storage
tanks to force any air out of the gas collection chambers.
A Next, plug the included power supply
into the hydrogen fuel cell. Using the
energy from the power supply, the water
in the storage tanks is electrolyzed, creating both hydrogen and oxygen gas.
