Students model and design the sound environment for a room. They analyze the sound performance of different materials that represent wallpaper, thick curtains, and sound-absorbing panels. Then, referring to the results of their analysis,...

In this video segment from Cyberchase, learn about the importance of creating a model as the CyberSquad designs a giant "Trojan Ducky" that will help them enter a fort without being noticed. [4:17]

The purpose of this activity is to introduce students to the concept of the engineering design process and to teach them how to apply it. In "Broken Bones," students will explore the steps of the engineering design process. They will...

Design and construct a glider that files! Compare the flights with classmates' prototypes to test the success of your design.

Think about the challenges that faced the Wright Brothers, then see if you can design and fly your own model aircraft. There are other sources provided to help you along the way.

To gain a better understanding of the roles and functions of components of the human respiratory system and our need for clean air, students construct model lungs that include a diaphragm and chest cavity. They see how air moving in and...

Students use their knowledge about how healthy heart valves function to design, construct and implant prototype replacement mitral valves for hypothetical patients' hearts. Building on what they learned in the associated lesson about...

Student teams practice water quality analysis through turbidity measurement and coliform bacteria counts. They use information about water treatment processes to design prototype small-scale water treatment systems and test the influent...

Students identify different bridge designs and construction materials used in modern day engineering. They work in construction teams to create paper bridges and spaghetti bridges based on existing bridge designs. Students progressively...

We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires...

Students learn about how biomedical engineers aid doctors in repairing severely broken bones. They learn about using pins, plates, rods and screws to repair fractures. They do this by designing, creating and testing their own prototype...

Pumps are used to get drinking water to our houses every day! And in disaster situations, pumps are essential to keep flood water out. In this hands-on activity, student groups design, build, test and improve devices to pump water as if...

In Activity 5, as part of the Going Public step, students demonstrate their knowledge of how potential energy may be transferred into kinetic energy. Students design, build and test vehicle prototypes that transfer various types of...

Students learn how engineers harness the energy of the wind to produce power by following the engineering design process as they prototype two types of wind turbines and test to see which works best. Students also learn how engineers...

Part of a materials science engineering course, a project through which students investigate the future of solar electricity by creating prototypes of solar cells. Students complete exercises in "project planning, analysis, design,...

A lesson through which students design and build a small trebuchet from everyday materials. After building and testing their models, students will compete to see whose prototype produces the farthest launch.

Students will design and build a prototype of an artificial limb using a simple syringe system as an introduction to bioengineering. Students will determine which substance water (liquid) or air (gas) will make the appendage more efficient.

A database of 20,000 currently available products from over 2,000 different companies. "Each product record contains a detailed description of the product as well as price, manufacturer and distributor information. You will also find...

An interesting biography of James Ritty and an account of how he invented the cash register. Included are pictures of his designs and the prototypes.

The Red Fort Complex was built as the palace fort of Shahjahanabad - the new capital of the fifth Mughal Emperor of India, Shah Jahan. Named for its massive enclosing walls of red sandstone, it is adjacent to an older fort, the...

Located in the historic centre of Isfahan, the Masjed-e Jame ('Friday mosque’) can be seen as a stunning illustration of the evolution of mosque architecture over twelve centuries, starting in ad 841. It is the oldest preserved edifice...
