This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the current, I, for each set resistance value, students plot the three points on a Cartesian plane and note the line that is formed. They also see the direct correlation between the amount of current flowing through the lamp and its brightness.
In this physics lab students will investigate whether Ohm's Law applies to common electric devices (incandescent light bulbs and LEDs). Students will design a controlled experiment, including a written procedure, and then conduct the experiment, collect and graph data. Students may submit their findings in a formal written report or through informal class discussion.
This set of problems provides students practice with calculations dealing with electric circuits. Each problem features an audio clip describing the solution process. 34 problems in the set
In this activity, students use the provided table to organize information about the average monthly time usage and energy consumption for all electrical appliances in their home. Upon collecting data and calculating costs, they draw conclusions regarding the types of appliances which are the biggest consumers of electrical energy. Teachers will need to supply the average cost of a kiloWatt-hour for the local area. Students will create a complete lab write-up at the conclusion of the activity.
In this introductory physics activity, students will investigate the basic requirements for electricity. They will create a simple circuit for a quiz board that will light up when the correct matching pair is selected. Students will create six questions and answers for the quiz board, using electricity vocabulary terms.
In this advanced physics lesson, students will review electricity and circuitry concepts through a Power Point presentation and then dissect a disposable camera to investigate the internal circuit structure.
Students explore the composition and practical application of parallel circuitry, compared to series circuitry. Students design and build parallel circuits and investigate their characteristics, and apply Ohm's law.
Background: students are familiar with static electricity, charge, and sparks. They also know about conservation of energy, forms of energy including potential energy, power, and work. Students will complete a variety of activities using breadboards, which will display various types of circuits and their effect on the flow of electricity.
Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.
In this lesson, students will consider how Germans resisted what the Berlin Wall symbolized during the Cold War by examining the musical cultures that developed in East and West Germany. To do this, students will watch clips from CNN Soundtracks and analyze primary and secondary historical sources such as newspaper articles, cartoons, interviews, and photographs.
This collection uses primary sources to explore the Texas Revolution. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.
The same interactions and outcomes in the simulation were also at work in Addie's body and also at work in our community over the past ninety years. Bacteria populations became more resistant to being killed by antibiotics as trait distributions in the population that granted them a competitive advantage for survival became more prevalent over many generations of exposure to antibiotics.
Think back to all you’ve done to learn about the evolution of bacteria and the spread of antibiotic-resistant bacteria in this unit.
Antibiotic resistance occurs when germs “outsmart” drugs. In today's healthcare and community settings, we are already seeing germs stronger than the drugs we have to treat them. This is an extremely scary situation for patients and healthcare workers alike
