Students consider the Earth's major types of landforms such as mountains, rivers, plains, hills, canyons, oceans and plateaus. Student teams build three-dimensional models of landscapes, depicting several of these landforms. Once the models are built, they act as civil and transportation engineers to design and build roads through the landscapes they have created. The worksheet is provided in English and Spanish.

Working in teams of three, students perform quantitative observational experiments on the motion of LEGO MINDSTORMS(TM) NXT robotic vehicles powered by the stored potential energy of rubber bands. They experiment with different vehicle modifications (such as wheel type, payload, rubber band type and lubrication) and monitor the effects on vehicle performance. The main point of the activity, however, is for students to understand that through the manipulation of mechanics, a rubber band can be used in a rather non-traditional configuration to power a vehicle. In addition, this activity reinforces the idea that elastic energy can be stored as potential energy.

Many hunters dream of shooting a buck so big that it makes headlines. So why would a hunter who kills the trophy of a lifetime decline to have it measured and entered in the record books?

Videos featuring Case IH harvesting equipment, including Axial-Flow Combines, Module Express Cotton pickers, and more.

This content contains grade level Personal Finance Case Studies, resources to help teachers teach, helpful guides for teachers to write their own case studies and sample case presentations and videos of past students. These are great resources to enhance your teachings, use as projects or year end assignments and to prepare students for case based instruction in their future post secondary or at case competitions.

Students will learn the consequences of not paying one’s debts and the choices of last resort for out-of-control debt. Students will explain how using [types of predatory loans] can cause a vicious cycle of debt. Bankruptcy is also introduced, and the various costs associated with bankruptcy are outlined. The students will discover what steps a person can take to avoid filing for bankruptcy, including seeing a credit counselor.

Students examine books, selected from the American Library Association Challenged/Banned Books list, and write persuasive pieces expressing their views about what should be done with the books at their school.

Students learn about power generation using river currents. A white paper is a focused analysis often used to describe how a technology solves a problem. In this literacy activity, students write a simplified version of a white paper on an alternative electrical power generation technology. In the process, they develop their critical thinking skills and become aware of the challenge and promise of technological innovation that engineers help to make possible. This activity is geared towards fifth grade and older students and computer capabilities are required. Some portions of the activity may be appropriate with younger students. CAPTION: Upper Left: Trey Taylor, President of Verdant Power, talks about green power with a New York City sixth-grade class. Lower Left: Verdant Power logo. Center: Verdant Power's turbine evaluation vessel in New York's East River. In the background is a conventional power plant. Upper Right: The propeller-like turbine can be raised and lowered from the platform of the turbine evaluation vessel. Lower Right: Near the East River, Mr. Taylor explains to the class how water currents can generate electric power.

This awesome science video outlines how and why engineers ask themselves "what-if" questions as they identify variables in the solutions to the problems they are working on.

Become a detective to solve the case of the smelly backpack! Act out the clues and draw conclusions to solve the mystery.

When Detective Bentley cannot figure out why his backpack is smelly, he retraces the events in his day to find clues. Taking on the role of detectives, the viewers act out the events of Bentley’s day and use textual clues to solve the case.

Learning Objective:
Draw conclusions from the facts presented in text and support those assertions with textual evidence.

Give a customer the correct amount of cash back in all "big bills."

This is a lesson about the role of robots in space exploration. Learners will examine their prior notions of robots and then consider the characteristics and capabilities of a robot, like the Cassini-Huygens spacecraft, that would be sent into space to explore another planet. Students compare robotic functions to human body functions. The lesson prepares students to design, build, diagram, and explain their own models of robots for space exploration in the Saturn system. This is activity 5 of 6 in the Saturn Educators Guide.

This is a lesson about light in the outer solar system. Learners will demonstrate the effect of the inverse square law of illumination with distance and connect this to the functioning of solar panels at Saturn. Requires a silicon solar cell (available at an electronics parts store for a few dollars) and a multimeter.

Shadows, shadows, everywhere! In this lesson, students read fiction, informational text, and poetry about shadows to extend their knowledge of the concept before casting their own shadow poetry.

This activity was designed for blind learners, but all types of learners can use it to gain hands-on experience with various tools and materials used in design and construction. The students will make molds and duplicates for an engraved image.
