Materials Engineering: Designing Walls

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

Scholars investigate an issue associated with food systems and design their own solutions. Working collaboratively, they follow each step in the design process to complete the 10th lesson of the 13-part Our Hungry Planet series.

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

To begin the learning about dams, learners read (or are read to, depending on the age group) a passage about how dams work. Next, they work in groups to use the materials provided to build a small scale working dam. After the experience,...

In the world of chemistry, efficiency is defined as: the work a system does, divided by the energy given to that system to complete the work. Sal illustrates this important chemistry concept by drawing a PV graph that shows a Carnot...

Design your own video game, engineer accident-proof highways, or even develop a new phone app! The Engineering Design Model can be used with all ages and in all subject areas to create a product, system or service. The resource explains...

How tall is your marshmallow structure? With limited supplies (including uncooked spaghetti noodles, masking tape, and one marshmallow), teams endeavor to support the marshmallow atop the tallest spaghetti structure they can build....

The challenge: determine whether a tank will float. A design activity has groups work as engineering teams in order to determine the stability of given tanks and liquid contents. The teams need to determine the equations to...

Students explore a computer-aided design program. Students chart out roller coaster design, computer graphics and architecture. Students focus on understanding the connections between mathematics, science, technology and innovation.
