Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoirs.

Students come to understand the basics of engineering associated with the use, selection, and properties of fabrics. A wide variety of natural and synthetic fibers are used in our clothing, home furnishings and in our travel and sports equipment. The specific material chosen for each application depends on how closely the properties of the material match the design needs. This activity focuses on the different characteristics of fabrics and shows students how natural and synthetic fabrics differ from one another. Students weigh the advantages and disadvantages of fabrics when considering the appropriate fabric to be used.

In this video segment adapted from FETCH!, contestants are challenged to use materials from a garbage dump to build a boat that floats, can be steered, and is propelled by something other than oars.

Understanding how phrases are built and function will be an invaluable tool for students. This tutorial features many examples to help the student in grasping grammar concepts.

The goal of this task is to use geometry study the structure of beehives. Beehives have a tremendous simplicity as they are constructed entirely of small, equally sized walls. In order to as useful as possible for the hive, the goal should be to create the largest possible volume using the least amount of materials. In other words, the ratio of the volume of each cell to its surface area needs to be maximized. This then reduces to maximizing the ratio of the surface area of the cell shape to its perimeter.

The Smithsonian's EdGate project provides this illustrated narrative site that explores the mapping of the American West accomplished by the 1804-06 Lewis and Clark expedition.

Learn about drawing shapes using only a compass and straight edge or ruler with out measuring any lengths or angles.

Take a look at how a mine develops from the exploratory stage to reclamation of the land.

One of the great architects of the twentieth century, this Finnish architect, designer, and town planner is featured by MOMA.

A terrific reference for music students and teachers! Explains the fundamentals of the major scale, provides diagrams, and audio clips to help children recognize this piece of music theory.

Listen and learn with this explanation of minor scales. Each description of harmonic, melodic, and minor scales provides an illustrated example, and audio clips.(Flash player is necessary to listen to these.)

These activities introduce students to the International Space Station and how rockets were vital to its construction. The provided lessons correlate to all subject areas.

Students conduct an experiment to determine how varying the composition of a construction material affects its strength. They make several adobe bricks with differing percentages of sand, soil, fibrous material and water. They test the bricks for strength by dropping them onto a concrete surface from progressively greater heights. Students graph the experiment results and use what they learn to design their own special mix that maximizes the bricks' strength. During the course of the experiment, students learn about variables (independent, dependent, control) and the steps of the engineering design process.

A collection of resources about domes that includes basic facts about domes, challenges faced by dome builders, famous domes from around the world, and a lab that helps you understand different kinds of materials used to construct domes. Also includes links to recommended websites on related topics. An excellent site for exploring Roman contributions to engineering and architecture.

Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.
