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.

This is a story about a potato…not any type of potato though. A potato who sits in the exact same spot on the couch every day using all of his devices (tv, phone, video games, etc). It’s a perfect life until the power goes out one day, and he has to find other things to do. He learns that he needs to have a balance between screen time and activities in the real world. Your job as an engineer is to design a gadget that will remind the potato when he needs to ditch the screens and get up and move. (You must incorporate your iPad.)

You are preparing your family’s emergency kits in case there is a need to leave your home quickly, or stay in your home without electricity or water. You need to be able to create an emergency supply kit that includes a lightweight water filtration device that is low cost. This will provide you with clean water regardless of your water source.

In this project, you will gain knowledge of natural disaster preparedness through the Red Cross Pillowcase project. You will research and experiment with the water cycle to learn how water is naturally filtered. You will then design and build a water filtration device that could filter water in an emergency situation.

Students will create a small planter for a type of soil and water. The planter can be made from any materials the student wants and must be able to maintain its shape and hold the soil and water without leaking.

Students learn about the role engineers and mathematicians play in developing the perfect bungee cord length by simulating and experimenting with bungee jumping using washers and rubber bands. Working as if they are engineers for a (hypothetical) amusement park, students are challenged to develop a show-stopping bungee jumping ride that is safe. To do this, they must find the maximum length of the bungee cord that permits jumpers (such as brave Washy!) to get as close to the ground as possible without going "splat"! This requires them to learn about force and displacement and run an experiment. Student teams collect and plot displacement data and calculate the slope, linear equation of the line of best fit and spring constant using Hooke's law. Students make hypotheses, interpret scatter plots looking for correlations, and consider possible sources of error. An activity worksheet, pre/post quizzes and a PowerPoint® presentation are included.

Student teams investigate the properties of electromagnets. They create their own small electromagnet and experiment with ways to change its strength to pick up more paper clips. Students learn about ways that engineers use electromagnets in everyday applications.

Students will build and launch Magnus Effect gliders and measure the distance they fly. They will analyze the data to judge which material gives the glider the most distance. Then they may do the same process for other variables.

Students construct a bridge that will get Cupid to his destination and withstand all of his Valentines. They will build a bridge with only candy hearts and toothpicks.

Students will work in small groups of 2 or 3 to design a zipline and zipline cart to carry coins from point “A” to point “B”. The goal of this activity is for students transport 82 cents the fastest from point “A” to point “B”. Groups must transport exactly 82 cents from the top of the zip line to the bottom. They must use at least 1 quarter, 1 dime, 1 nickel and 1 penny.

Students explore the many different ways that engineers provide natural lighting to interior spaces. They analyze various methods of daylighting by constructing model houses from foam core board and simulating the sun with a desk lamp. Teams design a daylighting system for their model houses based on their observations and calculations of the optimal use of available sunlight to their structure.

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.

Students will use the engineering design process to design and create a simple protective helmet to understand the role of the human skeletal system in protection, specifically the skull.
Understanding how the human body systems are essential for life: protection (skull protecting the brain), movement (discuss how the helmet design could allow for movement), and support (structure of the helmet supporting the egg).
This activity provides a hands-on, practical application of the engineering design process while reinforcing the importance of the skeletal system, specifically the skull, in protecting vital organs.

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.

Welcome to 2.007! This course is a first subject in engineering design. With your help, this course will be a great learning experience exposing you to interesting material, challenging you to think deeply, and providing skills useful in professional practice. A major element of the course is design of a robot to participate in a challenge that changes from year to year. This year, the theme is cleaning up the planet as inspired by the movie Wall-E.

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.

Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO© MINDSTORMS© NXT bricks and light sensors. They begin by analyzing a set of standard solutions with known concentrations of food coloring, and plot data to graphically determine the relationship between percent reflected light and dye concentration. Then they identify dye concentrations for two unknown solution samples based on how much light they reflect. Students gain an understanding of light scattering applications and how to determine properties of unknown samples based on a set of standard samples.
