 Review of the Summer 2019 Workshops

Legendary Projects: Model Boats for STEM  June 3-6, 2019  Normal, IL

The workshop started with each teacher forming a boat hull from clay. We then layed several layers of foil using spray adhesive over the clay to make an aluminum boat hull. These were pulled through a 20 ft tank to determine speed, capacity, wave generating, and stability. When these models were calculated at 3/4" = 1 ft scale, a penny is about 24 pounds and the boats run at 25% of the actual boat. We used these data to design our race boats. They, too, were first carved from clay, but this time only a half-hull model was formed. Measurements were taken from the model and scaled up to produce boat hulls ranging from 32 to 42 inches long. We were able to measure the water plane area and the pounds per inch immersion and use these data to calculate draft and center of bouyancy. Each teacher cut plywood panels to the right shape and held them together with tape and plastic ties before installing a putty fillet and fiberglass tape on the joints. Weed trimmer motors were modified and installed just aft of the center of bouyancy with the shaft extending through the bottom of the hull using a metal brake line as a stuffing box. Each teacher designed and installed their own rudder system and hooked up the rudder blade(s) and throttle to the radio control servos. We tried various propellers with varying degrees of success. Finally, on last afternoon we launched our boats in a nearby pond with none of them sinking. Throughout the week we spent considerable time discussing how this project could be implemented at the high school level with lots of good ideas being generated. It will be interesting to hear what happens this school year. Please contact me if you would like to see this workshop offered again.

DIY Automation June 24-25, 2019  Normal, IL

This 2-day workshop started wtih using simulation software to design simple circuits, then adding Raspberry Pi computers. Work then shifted to the actual devices with various programs written to control the circuils. Next, motors were added and code written to control their speed and direction. On the second day, various ideas were demonstrated and discussed for using the motors to automate various machines. A wide variety of applications were explored. Please contact me if you would like to see this workshop offered again. Dr. Brad Christensen at This email address is being protected from spambots.

Mathematics in CTE   June 26-27, 2019 Normal, IL

This workshop started with teachers experiencing a few lessons that teach Algebra I and Geometry content through its industrial application. We did not do story problems. Instead, these lessons teach the content the way it is experienced in a specific industry. For example, how are proofs used in a custom hot rod shop? We then gathered data from spaghetti bridges and modified the lesson to apply the concepts in a manufacturing/construction context. The second day involved designing and "crunching the numbers" on an electric vehicle. We first made clay models then measured the to determine scale. These data were used to calculate the force required to overcome rolling resistance, climb a hill, acceleration, and aerodynamic drag. The drag coefficent was determined by using a leaf blower on the clay model.  Finally we were able to select a motor and battery pack and calculate range. The workshop ended with building, flying, and calculating altitude of model rockets. Please contact me if you would like to see this workshop offered again.

Future workshops for Fall and Spring 2019/2020

We have several possibilities for workshops during the 2019/2020 school year including Green Construction, Smart Grid and Home Automation, Mathematics in CTE, and others. Please visit this website often to stay current on what is being offered. Contact Dr. Brad Christensen at This email address is being protected from spambots.

The CTE DIVISION at the Illinois State Board of Education (ISBE), has worked to provide resources for educators and student teachers through the Innovative Curriculum Project. All resources are deposited at the www.Ilcte.Org site for easy access. The mission of this web site resource is for enhancement and instructional program improvement in Career and Technical Education (CTE) programs throughout Illinois by aligning lessons with academic learning standards, workplace skills, and occupational skills standards..

We welcome input from you as  teachers in the field in the form of comments and suggestions, as well as materials that you are willing to share.  Contact the Technology & Engineering facilitator, Dr. Brad Christensen at This email address is being protected from spambots.
