Core Skills Analysis
Science
Conner made an antenna from wire and connected it to a television, exploring how a physical object could be used as part of a system for receiving broadcast signals. Through this hands-on activity, Conner encountered the idea that antennas interact with electromagnetic waves, which carry television information through the air. The activity connected an everyday device with practical experimentation and encouraged Conner to notice how materials and connections can affect a system’s operation.
Engineering and Technology
Conner assembled a wire antenna and hooked it up to a television, completing a simple build-and-connect task involving an electronic device. This gave Conner experience with designing a basic component, making a connection, and considering how one part can serve a purpose within a larger system. The activity also introduced practical problem-solving: creating something by hand and putting it to use with familiar technology.
Tips
Tips Turn Conner’s build into a mini investigation by sketching the antenna and television connection, then discussing how antennas receive signals. With adult supervision, compare reception in a few safe locations or orientations and record observations in a simple table. Explore how different antenna shapes are used for different purposes by looking at examples such as radio, television, and satellite antennas. Finish with a short design challenge: draw a revised antenna and explain what question Conner would test to evaluate the design.
