POWER SYSTEMS BUNDLE 1
Kit #AG-S05 $312.35 (Savings of $68 .55)

THIS BUNDLE CONTAINS THE FOLLOWING KITS:
39S Biofuels: Investigating Ethanol Production
and Combustion Developed by SEPUP LITERACY STEM AG REFILLABLE ADD A GROUP
This activity includes three major parts .
• Investigation One - students observe a demonstration of the fermentation of corn and cane sugar, the two food
sources used most commonly to produce ethanol, and the distillation of the fermented stillage to produce fuel .
• Investigation Two - students investigate the energy released by the combustion of ethanol and kerosene and
compares the results .
• Investigation Three - students measure and compare two byproducts - CO and particulate matter - of the two fuels .
2
Students compare results and discuss the trade-offs of biofuels and fossil fuels as sources of energy .
Accommodates 6 groups of four students.
38 Modeling and Comparing Fossil Fuel
and Biofuel Combustion LITERACY STEM AG ADD A GROUP NONCONSUMABLE
In Part One of this activity, students use Lab-Aids Molecular Models to build methane, ethanol, and octane molecules
®
then “combust” them with oxygen molecules . “Combusting” the model molecules helps students determine the
balanced chemical equations for the combustion reactions and compare the amount of carbon dioxide released when
these three fuels are burned . In Part Two students use standard bond energies to calculate and compare the amount of
energy released during the combustion reactions they modeled in Part One . They are then asked to use their data about
the energy released and the CO produced to choose which fuel they think is better .

Accommodates unlimited classes, each with 12 groups of two students.

POWER SYSTEMS BUNDLE 2

Kit #AG-S06 $438.25 (Savings of $96 .25)
THIS BUNDLE CONTAINS THE FOLLOWING KITS:
205S Investigating the Design and Output of
Wet Cell Batteries Developed by SEPUP STEM ADD A GROUP AG LITERACY REFILLABLE
This kit introduces students to the concept of energy conversion through the study of a simple electrochemical cell
connected to an electric motor . Students design and conduct an experiment that uses the unique Lab-Aids Wet Cell
®
Chamber to determine which combination of different metals works best to convert the potential chemical energy into
electric energy . Their results allow them to rank the metals tested in order of reactivity . They also investigate how the
distance between the metals, the direction of current flow and the amount of metal surface area impacts the electrical
output of the wet cell .
Accommodates 6 groups of four students. LITERACY STEM AG

220S Investigating Photovoltaic Cells Developed by SEPUP ADD A GROUP NONCONSUMABLE
Students use photovoltaic cells to transform energy from sunlight into electrical energy as they investigate solar
energy as an example of a renewable energy source . They explore how to power a motor using the photovoltaic cells
and investigate some factors that affect the cells’ ability to transform light energy into electricity . They then discuss
the advantages and disadvantages of using solar energy .
Accommodates unlimited classes, each with 6 groups of four students. AG LITERACY ADD A GROUP
213 Energy Transfer: Motors, Generators and Sources of Electricity STEM NONCONSUMABLE
Students explore the relationship between, and practical applications of, electricity and magnets . They use a battery,
a magnet and a coiled wire to build a simple electric motor and then use a pre-assembled electric motor to generate
electric current . In Activity 2, students read about how electricity is generated for home and commercial use . They
compare the methods and equipment needed to convert energy carried by renewable and nonrenewable resources into
electric current . Six D-cell batteries required but not included with the kit.
Accommodates unlimited classes, each with 6 groups of four students.
