As the world gets more digital, the world will need more sensors. A sensor is something that records the environment around it. Sensors can measure temperature, light, or sound among other things. Where can you find a sensor?  This resource is part of the Agricultural Cyberbiosecurity Education Resource Collection that contains resources for formal and non-formal agricultural educators working with middle school aged youth. Published as Open Educational Resources, all resources are provided in durable (pdf) and customizable (MS Word) formats. They are hosted on  GoOpenVA in a unique resource collection, Ag Cybersecurity Virginia Tech, at https://goopenva.org/curated-collections/143 and on on Virginia Tech’s stable repository, VTechWorks at https://doi.org/10.21061/cyberbiosecurity

This lesson explores the similarities between how a human being moves/walks and how a robot moves. This allows students to see the human body as a system, i.e., from the perspective of an engineer. It shows how movement results from (i) decision making, i.e., deciding to walk and move, and (ii) implementing the decision by conveying the decision to the muscle (human) or motor (robot).

With advances in AI, it is more important than ever that we consider how humans and computers will interact. How do you want the robots of the future to behave towards you and others? For this activity, students will make a “robot zine” where they will sketch an original robot design, identify how their robot will sense the world around it and write a code of conduct to describe how their robot will interact with humans.

Students learn how roadways are designed and constructed, and discuss the advantages and limitations of the current roadway construction process. They look at current practices of roadway monitoring, discuss the limitations, and consider ways to further road monitoring research. To conclude, student groups compete to design smooth, cost-efficient and sound model road bases using gravel, sand, water and rubber (representing asphalt). This lesson prepares students for the associated activity in which they act as civil engineers hired by USDOT to research through their own model experimentation how to best use piezoelectric materials to detect road damage by showing how piezoelectric transducers can indicate road damage.

Acting as civil engineers hired by the U.S. Department of Transportation to research how to best use piezoelectric materials to detect road damage, student groups are challenged to independently create their own experiment procedures, working with given materials and tools. The general approach is that they set up model roads using rubber mats to simulate asphalt and piezoelectric transducers to simulate the in-ground road sensors. They drop heavy bolts at various locations on the “road,” collecting data and then analyzing the voltage changes across the piezoelectric transducers caused by the vibrations of the bolt hitting the rubber. After making notches in the rubber “road” to simulate cracks and potholes, they collect more data to see if the piezo elements detect the damage. Students write up their research and conclusions as if presenting evidence to USDOT officials about how the voltage changes across the piezo elements can be used to indicate road damage and extrapolated to determine when roads need maintenance service.

Developed by the Science Museum of Western Virginia, this educator outline is intended to assist in guiding middle school-aged students through various activities using the Rokit Smart robot kit. The Rokit Smart utilizes Arduino, a widely-used open-source environment for programming that enables users to create interactive electronic objects.  Designed through modules, the activities can be grouped to fit after-school, summer camp, or other student enrichment needs.  

Students learn how different characteristics of shapes—side lengths, perimeter and area—change when the shapes are scaled, either enlarged or reduced. Student pairs conduct a “scaling investigation” to measure and calculate shape dimensions (rectangle, quarter circle, triangle; lengths, perimeters, areas) from a bedroom floorplan provided at three scales. They analyze their data to notice the mathematical relationships that hold true during the scaling process. They see how this can be useful in real-world situations like when engineers design wearable or implantable biosensors. This prepares students for the associated activity in which they use this knowledge to help them reduce or enlarge their drawings as part of the process of designing their own wearables products. Pre/post-activity quizzes, a worksheet and wrap-up concepts handout are provided.

Students apply their knowledge of scale and geometry to design wearables that would help people in their daily lives, perhaps for medical reasons or convenience. Like engineers, student teams follow the steps of the design process, to research the wearable technology field (watching online videos and conducting online research), brainstorm a need that supports some aspect of human life, imagine their own unique designs, and then sketch prototypes (using Paint®). They compare the drawn prototype size to its intended real-life, manufactured size, determining estimated length and width dimensions, determining the scale factor, and the resulting difference in areas. After considering real-world safety concerns relevant to wearables (news article) and getting preliminary user feedback (peer critique), they adjust their drawn designs for improvement. To conclude, they recap their work in short class presentations.

This activity is about how you form mental images of your body's position in space, independent of vision. Can you take a sip of water from a cup with your eyes closed? If so, how are you able to navigate this maneuver without seeing the cup? Find out here!
