Electric Current and Circuits
Compare the drift speed of conduction electrons in a current-carrying wire to the signal speed of changes in current. They also distinguish between DC and AC and describe how AC is converted to DC.
Curated OER
Series/Parallel Circuits
Students engage in a lesson that is concerned with the concept of series and parallel circuits. They conduct research using a variety of resources. They have class discussion and the lesson includes information for the teacher to use.
Curated OER
Understanding Pi.
Students study the relationship between circumference and diameter to come up with Pi. "In this pi lesson, students measure, record and find the ratio "circumference/diameter" and their average which is an approximation of pi.

Through Other Eyes
High schoolers describe the structures of crustaceans and the features that give organisms capabilities that exceed those of humans. In this investigative lesson plan students replicate some of the features of photo-receptors in a...
Curated OER
What "Ohm's" You?
Students use the CBL and voltage probe to observe electricity. In this algebra lesson plan, students use the TI calculator with the CBL to explore Ohm's Law. They discuss exponential equations and how it relates to Ohm's Law.
Curated OER
Stellar Spectroscopy
Students investigate white light. In this science lesson, students participate in a variety of experiments in which they study light. Students use spectroscopes to view the components of light.
Curated OER
Electrical Resistivity
Students examine how materials oppose the flow of an electrical current. In this resistivity lesson students complete several experiments on the differences between resistance and resistivity.
Curated OER
Series and Parallel Circuits
Students explore the differences between a parallel and a series circuit.In this current lesson students complete several experiments using a light bulb.
Curated OER
Ohm's Law
Students explain the meaning of Ohm's Law, and plot a graph of voltage versus current, by explaining how the slope is the resistance of the circuit.
