Students construct a homopolar motor following certain procedures. In this physics lesson, students explain how generators and motors work. They compare and contrast the characteristics of both.

In this dilemmas and problem solving worksheet, learners read 8 problematic situations. Students write a solution for what could be done to solve each problem.

Here, learners review telling time using an analog clock. They use a clock to tell time, make a paper clock, and discuss the concept of elapsed time. However, the lesson is not always easy to follow, nor are the questions clear.

Students explore the five essential parts of every robot and design their own robots to perform everyday tasks. They explore robots created for fighting competitions by reading and discussing "When Nerds Collide: Robots at War."

In this lesson, students explore the history, relevance and current application of international tribunals for war crimes. Students look at cases from the Nuremberg trials, Tokyo trials and the Bosnian War.

Students demonstrate the process of science by posing questions and investigating phenomena through language, methods and instruments of science as they experiment at four teacher-created stations to explain the fundamentals of magnetism.

Students explore the basis of Iago's persuasive power by analyzing his astonishing command of rhetoric and figurative language. The diverse set of activities below include short group performances, writing exercises and the guided use of...

Sixth graders use a laser along with computer microphone probeware and the appropriate software, 6th graders determine the speed of rotating objects.An audio amplifier is connected to a solar cell to change the laser light signal into a...

Ninth graders use online tutorials, class discussion, presentations and scientific articles to explore types of cells along with cell structure, function and behavior. They explore ethical questions related to cells and disease.

Students use video learning and construct electromagnets and use them to collect data, graph, and share with others.

Learners discuss benefits of global positioning systems (GPS) and practice using them on the school grounds. A personal navigator, such as, the Garmin eTrex is necessary for this lesson.

Fifth graders, in groups, create paper bag "globes", complete with magnetic poles. They use compasses to determine and label various locations (N. and S. Poles, Prime Meridian, Equator, etc.) and finish it by drawing in the continents...

Students work together to identify sources of hazardous waste in their community. They discover the threat it poses to the environment. They examine how to properly dispose of hazardous waste as well.

Learners examine the effect of hazardous chemicals on humans. They discover how the chemicals are cleaned up and the facilities in their neighborhood. They identify federal and local agencies that oversee environmental hazards

Seventh graders define race, ethnic group, and culture. They identify the ways in which words are used in political cartoons and examine the way visual elements in a cartoon determine the meaning of words and enhance their impact. They...

Learners gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. They build a conductivity tester to determine whether different objects are...

Students participate in a scavenger hunt and a drawing activity to examine the use of Global Positioning Systems including a handheld GPS receiver for personal navigation. They practice using the GPS receivers while collecting data from...

Students investigate how a simple series circuit functions. They design and construct a working portable flashlight, develop a written plan for the flashlight, test their flashlight for functionality and reliability, and draw the series...

Middle schoolers visualize a communication system. They encode, decode, transmit, receive and store messages. Students use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve...

Students discuss certain properties of salt and how it is used every day as well as harmful uses. They experiment with salt to see it conduct electricity, form crystals and water freezing temperature. They complete a worksheet to record...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Students review the difference between "wants" and "needs." Students apply acquired knowledge by preparing for a pretend camping trip. Students plan out their trip together and then revise their list twice.

Students analyze an engineering problem. They contrast paper and pencil mastery of concepts with hands-on mastery. They present their design and rationale behind it, whether it works or not.
