Power Systems Bundle 2
Investigating the Design and Output of Wet Cell Batteries (#205S): This kit introduces students to the concept of energy conversion through the study of a simple electrochemical cell connected to an electric motor. Electrochemical cells are the basis for batteries and contain metals and other chemicals with stored chemical potential energy. Students design and conduct an experiment that uses the unique Lan-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.
Investigating Photovoltaic Cells (#220S): 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 cellsí ability to transform light energy into electricity. They then discuss the advantages and disadvantages of using solar energy. Energy Transfer: Motors, Generators and Sources of Electricity (#213) 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 non-renewable resources into electric current.

Scientific Concepts
•Energy is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical.
•In most reactions, energy is transferred into or out of a system.
•Students design and conduct a scientific investigation.
•Students use appropriate tools and techniques to gather, analyze, and interpret data.
•Students use evidence to develop descriptions, explanations, predictions, and models.
•Energy is transferred in many ways.
•Electrical circuits provide a means of transferring electrical energy.
•The Sun is a major source of energy.
•Students design and conduct a scientific investigation.
•Students develop descriptions, explanations, predictions, and models using evidence.
•Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical. Energy is transferred in many ways.
•Electrical circuits provide a means of transferring electrical energy when heat, light, sound, and chemical changes are produced.
•Important personal and social decisions are made based on perceptions of benefits and risks.
•Electricity and magnetism are two aspects of a single electromagnetic force. Moving electric charges produce magnetic forces and moving magnets produce electric forces. These effects help students understand electric motors and generators.
•The earth does not have infinite resources; increasing human consumption places severe stress on the natural processes that renew some resources, and it depletes those resources that cannot be renewed.
•Materials from human societies affect both physical and chemical cycles of the earth.
•Many factors influence environmental quality.
