Engineering Design Process PowerPoint

(View Complete Item Description)

This PowerPoint is a generic description of the Engineering Design Process that walks students through the 6 step process that works in a continual loop of defining the problem, generate concepts, develop a solution, construct and test a prototype, evaluate a solution, and present a solution. This PowerPoint offers stopping points to encourage question and answer sessions as well as discussion opportunities if teachers choose to relate it to a particular problem. It was originally posted and authored by Alexandrea Dunkelberger.

Solar Cookers

(View Complete Item Description)

In this project students will research and then build a basic solar cooker shell made out of cardboard. Then they will run a variety of materials through experiments. Data from the experiments will be used to determine which materials should be added to the solar cooker shell to improve its ability to heat up food. This project was created as a collaboration between a science and an engineering/woodshop class. The engineering class researched and build the basic solar cooker cardboard shells. The science class tested additional materials to add to the shells to improve the solar cookers. Then the engineering class, following the directions from reports created by the science class, added the materials to the solar cooker shells to create the final products.

Zipline Target Drop

(View Complete Item Description)

A park ranger needs to build a zipline to drop food supplies to her mentor park ranger at the bottom of a gorge. Unfortunately, she does not have the instructions to build the zipline according to the proper specifications. Without directions, she is unsure of the correct angles to attach her zipline to each tree. Additionally, she needs to figure out how to open the chute to drop the food supplies.  Challenge: Create a zip line that will release from her bucket (paper cup) the food supplies (represented by a marble) onto the target (placed 5/8 of the way down the zipline)  before the gear reaches the opposite end of the zip line.

Ramp and Review (for High School)

(View Complete Item Description)

In this hands-on activity rolling a ball down an incline and having it collide into a cup the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables and review the relationships between these concepts.

Does It Cut It? Understanding Wind Turbine Blade Performance

(View Complete Item Description)

Students gain an understanding of the factors that affect wind turbine operation. Following the steps of the engineering design process, engineering teams use simple materials (cardboard and wooden dowels) to build and test their own turbine blade prototypes with the objective of maximizing electrical power output for a hypothetical situation—helping scientists power their electrical devices while doing research on a remote island. Teams explore how blade size, shape, weight and rotation interact to achieve maximal performance, and relate the power generated to energy consumed on a scale that is relevant to them in daily life. A PowerPoint® presentation, worksheet and post-activity test are provided.

Electric Field Hockey (AR)

(View Complete Item Description)

Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.

Coding and Computer Science-VEX Robotics-Intermediate

(View Complete Item Description)

In this lesson students will become familiar with the Interface, learning how to setup the Robot and sensors. Students also examine Robot virtual worlds. Students then study robot movement by studying motor polarity, how to rename motors, and how to use time as a variable. Students then continue looking at movement by learning how to control speed and direction, studying specifically Motor Power Levels, Turning and Reversing, and Manual Straightening. Students complete the Pathway by learning how to accomplish a specific task with their robot, studying the use of shaft encoders as a variable instead of time, writing conditional statements, and how to use the sensor debug window.

Spaghetti Bridge

(View Complete Item Description)

Civil engineers design structures such as buildings, dams, highways and bridges. Student teams explore the field of engineering by making bridges using spaghetti as their primary building material. Then they test their bridges to see how much weight they can carry before breaking.

Balsa Towers

(View Complete Item Description)

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.
