Combustion Process

Strand/Standard CHEM.2.3 Plan and carry out an investigation to observe the change in properties of substances in a chemical reaction, and relate the macroscopically observed properties to the molecular level changes in bonds and the symbolic notation used in chemistry. Emphasize that the visible macroscopic changes in chemical reactions are a result of changes on the molecular level. Examples of observable properties could include changes in color or the production of a solid or gaseous product. (PS1.B)

Lesson Performance Expectations

Students investigate the products of a combustion reaction. Students will learn tests to identify gases.

Thermal Energy Conversion Using Peltier Power

Strand/Standard PHYS. 2.4 Design a solution by constructing a device that converts one form of energy into another form of energy to solve a complex real‐life problem. Define the problem, identify criteria and constraints, develop possible solutions using models, analyze data to make improvements from iteratively testing solutions, and optimize a solution. Examples of energy transformation could include electrical energy to mechanical energy, mechanical energy to electrical energy, or electromagnetic radiation to thermal energy. (PS3.A, PS3.B, ETS1.A, ETS1.B, ETS1.C) (PS4.A, PS4.B, PS4.C).

Lesson Performance Expectations

Students will build and map the energy flow through a circuit. Students will observe energy transformed from heat into electrical energy with a thermoelectric device (Peltier Plate).

Heat Exchangers

Strand/Standard PHYS 2.4 Define a problem and propose a solution for a major global challenge that specifies qualitative and quantitative criteria and constraints and that accounts for societal needs and wants. Emphasize problems that require the application of conservation of energy principles through energy transfers and transformations. Examples could include feasibility studies to examining the capacity renewable energy resources to perform functions currently performed by nonrenewable fuels.

Lesson Performance Expectations

Students will design an energy efficient heating and cooling system for a home, using the principles of energy exchange. Students will understand the economic and environmental significance of conserving heat and preventing energy waste in home heating and cooling.

Exploring Energy Conversions with Wind Power

Strand/Standard: Physics 2.4 Design a solution by constructing a device that converts one form of energy into another form of energy to solve a complex real-life problem. Define the problem, identify criteria and constraints, develop possible solutions using models, analyze data to make improvements from iteratively testing solutions, and optimize a solution. Examples of energy transformation could include electrical energy to mechanical energy, mechanical energy to electrical energy, or electromagnetic radiation to thermal energy. (PS3.A, PS3.B, ETS1.A, ETS1.B, ETS1.C)

Lesson Performance Expectations

Students will create a device that converts kinetic wind energy into electricity and evaluate their design.
