Using a question and answer format, this page explains the details of how a jet engine can be started. The different types of starters and when they are usually used is discussed.

In this lesson the students will learn how to classify the materials as mixtures, elements and compounds and identify the properties of each group. Also the concept of separation of mixtures will be introduced to the students. Since...

Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a...

With real-life materials and exciting tools to touch and explore, engineering activities are a natural draw for many young children. In this professional development experience with Ready, Jet, Go!, we'll look at teacher practices for...

In this interactive lesson, students will experience the engineering design process as an aerospace engineer assigned to design and test an airplane.

Can you build a blimp that hovers, and then modify it to use balloon power to travel in a straight path across the room? Try it!

Students use their understanding of projectile physics and fluid dynamics to find the water pressure in water guns. By measuring the range of the water jets, they are able to calculate the theoretical pressure. Students create graphs to...

During this performance test, student will design a plane, The plane must be able to take off and land on an average runway and demonstrate satisfactory climbing and turning performance.

Discusses the various types of jet engines and explains how they produce their power. Describes the primary components of jet engines and their respective roles.

From the Smith College Museum of Ancient Inventions website. Description of Heron's invention of the aeolipile - a precursor to the steam engine. Includes a graphic depicting a replica of the device.

Discover how an electrical engineer is using artificial intelligence to make robots "smarter." Consider how robots can be used to explore other planets.

Wikipedia provides an encyclopedia definition of a rocket, including information on rocket history, size, types, and more.

Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project. When a ship rocks back and forth, it can make people seasick, but also it makes it dangerous for jets to land...

This complete chronology of steam power is designed in time line fashion. Next to each year is a detailed description of the invention. Another useful aspect of this site is the "Link to the decades," found at the top of the page. Each...

Today, when most people think of a printer, they think of a laser jet printer that prints ink on paper. But thanks to new technology, engineers have developed 3D printers that can print objects-and even food. As you read, take notes...

Take a trip on an oil rig to view how oil is drilled. This documentary shows how gas and petrol is refined from crude oil. See a pumping jack in action as it harvests "Texas's gold". Follow the crude oil as it travels through pipes to an...
