Science NetLinks Engineers Week Feature
Science NetLinks | Resource Collection | K-12
29 Lessons, tools, podcasts and other resources from our science expert, the American Association for the Advancement of Science, created to introduce engineering concepts and careers to students of all ages.

Engineering Project Spotlight
Xpeditions | Activity | 9-12
Show students how geography and engineering are connected in this freshwater resource-management project.

Roller Coasting Through Function
Illuminations | Lesson | 6-8
Using tables and graphs to analyze the falls of different roller coasters, students determine the time it takes for a roller coaster to reach the bottom of its tallest drop. They conclude the study by creating their own roller coaster and analyzing its fall.

The Water-Treatment Process
Xpeditions | Activity | 5-12
Students learn the process of making water potable and how engineering makes the process possible.

Waterworks Around the World
Xpeditions | Activity | 9-12
Students learn about freshwater projects implemented globally by an engineering company and identify the geographic location of each project.

Break It Down
Science NetLinks | Interactive | 3-5
Use ramps, switches and gears to move a marble toward the lever that ultimately raises the flagpole, and learn a lot about systems and systems design along the way.

Building Height
Illuminations | Lesson and Activity | 6-8
Students use a clinometer and isosceles right triangles to measure the height of a building. The class will compare measurements, discuss the variations in their results, and select the best measure of central tendency to report the most accurate height.

The Bridge Over the Hellespont
EDSITEment | Interactive | 9-12
Xerxes's Phoenician and Egyptian engineers built two bridges across the Hellespont, the waterway between Asia Minor (modern Turkey) and Greece. This waterway also connects the Black Sea to the Aegean part of the Mediterranean Sea. With this interactive, build your own bridge to cross the Hellespont!

Deanne Bell believes engineering is for girls
History Explorer | Podcast | 5-12
Deanne Bell, engineer and co-host of PBS's "Design Squad," talks about inspiring inventive creativity in young people, especially girls. Listen to the podcast or read the transcript.

I Hear the Locomotives
EDSITEment | Lesson Plan | 3-5
Analyzing archival material such as photos, documents, and posters, students can truly appreciate the phenomenon of the Transcontinental Railroad. Help your class make connections between the arrival of the railroads and many of the changes occurring in the United States and its territories

Gecko Feet
Science NetLinks | Podcast | 6-12
Nature is a great engineer, in part because useful natural materials have millions of years to evolve and improve. Hear how engineers are trying to imitate the amazing properties of the gecko’s toes.

Invention Playhouse
History Explorer | Interactive | K-12
Explore the playful side of invention and the inventive side of play in the Invention Playhouse, part of the Invention at Play online exhibition from the Lemelson Center at the Smithsonian's National Museum of American History. Through the use of four interactive games, students will learn how play-the ordinary and everyday "work of childhood"-connects to the creative impulse of both historic and contemporary inventors.

Contractor for a Day
Illuminations | Lesson | 6-8
Break out the tool belts and hard hats! In this lesson students explore the surface area in the same way a contractor might when providing an estimate to a potential customer. Once the customer accepts the estimate, a more detailed measurement is taken and a quote prepared.

Leonardo Da Vinci: Creative Genius
EDSITEment | Lesson Plan | 6-8
Students will discover why Leonardo is considered the ultimate Renaissance man. They will learn about his famous notebooks, focusing upon his machines of motion, then zooming in on the flying machines. As a culminating activity, the students will describe how Leonardo epitomizes the Renaissance man, by discussing this remarkable artist and inventor through the amazing variety of his creativity.

Thomas Edison’s Inventions in 1900 and Today: From New to You
EDSITEment | Lesson Plan | 3-5
The purpose of this lesson is to familiarize students with life and technology around 1900 in order to better understand how Edison influenced both. Through comparing and contrasting life and technology in the early part of the twentieth century with technology found in their own homes and experiences, students will gain a greater understanding of how far the fields of industry and entertainment have progressed since Edison's day and of how Edison's work was the foundation for technology they enjoy today.

Wheelchairs
Science NetLinks | Podcast | 6-12
Generally, the developed countries export new technology to poorer, developing ones. But when it comes to wheelchairs, it can work the other way around. This story looks at an organization that counts on some of the world's poorest countries to develop some of the most innovative new ideas.
