Student groups create working radios by soldering circuit components supplied from AM radio kits. By carrying out this activity in conjunction with its associated lesson concerning circuits and how AM radios work, students are able to identify each circuit component they are soldering, as well as how their placement causes the radio to work. Besides reinforcing lesson concepts, students also learn how to solder, which is an activity that many engineers perform regularly giving students a chance to be able to engage in a real-life engineering activity.

These 3 lessons are for high ABE/low ASE students at a level D-E Reading level to practice identifying key points in video and text and analyzing the causes and effects of social issues, and identifying solutions to these problems. By watching two short videos and reading EPA materials on the effects of lead exposure and a short article on the specific drinking water crisis in Flint, MI, students will examine key issues, analyze the problem and its causes, identify approaches to solving this problem and ones like it in other locations, and apply this approach to other scenarios that are relevant to their immediate lives.
Bismuth has been known since the early fifteenth century, but was often confused with lead and tin until Claude Geoffrey the Younger clearly proved its distinctiveness in 1753. Bismuth can be found as crystals of the native metal, but is most often obtained from metallurgical byproducts such as lead bullion from smelting of lead, silver, copper, or gold. Bismuth has the lowest thermal conductivity of all metals. Because bismuth melts at 545 degrees kelvin, it is used in low-melting alloys with tin and cadmium for such products as electric fuses, solder, and fire detectors. Bismuth is also used in pharmaceuticals, medicine, and cosmetics such as lipstick and eye polish.
