This unit is centered on designing a shoe for a customer. Students decide on a particular type of shoe that they want to design and utilize ideas of force, impulse, and friction to meet the needs of a particular customer. Force plates are used study the relationship between force, time, and impulse to allow students to get the mathematical models that allow them to make data informed decisions about their shoe design.

Widespread damage from flooding at the Texas Medical Center in Houston revealed the complex's vulnerabilities. Implementing a long-term hazard mitigation plan is reducing future risks.

This lesson teaches the engineering method for testing wherein one variable is changed while the others are held constant. Students compare the performance of a single paper airplane design while changing the shape, size and position of flaps on the airplane. Students also learn about control surfaces on the tail and wings of an airplane.

Students groups use balsa wood and glue to build their own towers using some of the techniques they learned from the associated lesson. While general guidelines are provided, give students freedom with their designs and encourage them to implement what they have learned about structural engineering. The winning team design is the tower with the highest strength-to-weight ratio.

Students use the scientific method to determine the effect of control surfaces on a paper glider. They construct paper airplanes (model gliders) and test their performance to determine the base characteristics of the planes. Then they change one of the control surfaces and compare the results to their base glider in order to determine the cause and effect relationship of the control surfaces.

Students will understand the structural importance of the arch shape in bridge design. Students will compare and contrast modern arch bridges to historical arch bridges. Students will design and sketch their own arch bridge design.

Students will understand what a cable-stayed bridge is and its structural importance. Students will identify the different key parts of a cable-stayed bridge. Students will study how the forces of compresion and tension are distributed on this type of bridge. Students will make comparisons between cable stayed bridges and other bridges that they are familiar with. Students will design and construct a scale sketch of their own cable-stayed bridge.

Students will understand how suspension bridges work. Students will identify the main parts of a suspension bridge. Students will know the signifigance of suspension bridges to modern construction. Students will design and draw their own suspension bridge. Students will learn what civil engineers put into consideration when designing a suspention bridge.

Students will learn the geometry and structural importance of a truss which allows it to be used to make bridges. Students will work in pairs to design, build, and test the strength of their own small wooden truss bridge. Students will know the importance of materials used in truss bridges.

Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.

Using third grade Michigan Science Standards students will learn about force and motion then design, describe, and create an arcade game for others to play.  Since this is a PBL, many ELA content standards are also included.

Students learn about the many types of expenses associated with building a bridge. Working like engineers, they estimate the cost for materials for a bridge member of varying sizes. After making calculations, they graph their results to compare how costs change depending on the use of different materials (steel vs. concrete). They conclude by creating a proposal for a city bridge design based on their findings.

Engineers use a series of steps called the design process to solve a problem. In this resource, featuring video segments excerpted from DESIGN SQUAD, watch teams of kids work through each of the five steps of the design process: 1) identify the problem; 2) brainstorm; 3) design; 4) build, test, evaluate, and redesign; and 5) share solutions.

As students learn more about the manufacturing process, they use the final prototypes created in the previous activity to evaluate, design and manufacture final products. Teams work with more advanced materials and tools, such as plywood, Plexiglas, metals, epoxies, welding materials and machining tools. (Note: Conduct this activity in the context of a design project that students are working on; this activity is Step 6 in a series of six that guide students through the engineering design loop.)

Student teams design and create LEGO® structures to house and protect temperature sensors. They leave their structures in undisturbed locations for a week, and regularly check and chart the temperatures. This activity engages students in the design and analysis aspects of engineering.

Students are given a biomedical engineering challenge, which they solve while following the steps of the engineering design process. In a design lab environment, student groups design, create and test prototype devices that help people using crutches carry things, such as books and school supplies. The assistive devices must meet a list of constraints, including a device weight limit and minimum load capacity. Students use various hand and power tools to fabricate the devices. They test the practicality of their designs by loading them with objects and then using the modified crutches in the school hallways and classrooms.

After a discussion about what a parachute is and how it works, students create parachutes using different materials that they think will work best. They test their designs, and then contribute to a class discussion (and possible journal writing) to report which paper materials worked best.

In this two-part activity, students design and build Rube Goldberg machines. This open-ended challenge employs the engineering design process and may have a pre-determined purpose, such as rolling a marble into a cup from a distance, or let students decide the purposes.

Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. Students learn the steps that engineers use to design bridges: understanding the problem, determining the potential bridge loads, calculating the highest possible load, and calculating the amount of material needed to resist the loads.

Students learn the engineering design process by following the steps, from problem identification to designing a device and evaluating its efficacy and areas for improvement. A quick story at the beginning of the activity sets up the challenge: A small child put a pebble in his ear and we don't know how to get it out! Acting as biomedical engineers, students are asked to design a device to remove it. Each student pair is provided with a model ear canal and a variety of classroom materials. A worksheet guides the design process as students create devices and attempt to extract pebbles from the ear canal.
