This unit will be taught to four sixth grade general science classes at Betsy Ross Arts Magnet School in New Haven, CT. Science is departmentalized at Betsy Ross and each class period is approximately fifty-two minutes long. The sixth grade curriculum has four science standards that must be taught throughout the year and these are Ecosystems, Simple Machines, How Technology Impacts Our Waters, and Weather. Two of the standards, Ecosystems and Simple Machines, will be able to be broadened through this proposed unit. Students will gain insight into ecosystems that that exist within their own bodies and to define themselves as being more symbiotic with microorganisms then they could imagine. They will also see that with the new knowledge of using nanotechnology, machines the size of molecules can help to fight diseases. They will learn to convert metric units of measurements to the nanoscale. They will come to understand that instead of taking something large, like a block of wood, and carving it down to the size of a table; they will build from something very small to a larger scale.
