The purpose of this lesson from Science NetLinks, is to explore how technology has been used to enhance human abilities. In this lesson students will explore various ways in which technology has enhanced human abilities. Middle school students are interested in machines that support or enhance life function, so they should also look at ways in which people use various machines to improve speed, mobility, strength, hearing, seeing, etc. Whenever students learn something about the ways that technology helps human beings, they also learn something about human capabilities and limitations.
Horse racing, the so-called "sport of kings," has captivated fans for centuries. One reason is the grace and agility of the horses themselves -- when they're running at top speed, they look as if they're flying down the track. In this Science Update, you'll hear how studying horses may help engineers improve human flight in air and space.
Dr. Evans compares the activity of a normal mouse to one with a mutation in a key gene controlling obesity. Also featured on the DVD Science of Fat, available free from HHMI. This video is 29 seconds in length, and available in MOV (6 MB) and WMV (8 MB). All Obesity videos are located at: http://www.hhmi.org/biointeractive/obesity/video.html.
In this activity from Science NetLinks, students use Internet resources to explore ways in which food provides energy and materials for their bodies. In the elementary grades, particularly the lower-elementary level, children know that there are different foods--some 'good' and some 'bad.' They also seem to understand that a person's height and size can depend on what he/she eats. In this investigation, students will use online resources to help them explore how food can affect their overall health.
A robotic arm that can be worn at home may someday help stroke victims regain lost mobility. It's being developed by Arizona State University bioengineer Jiping He and his colleagues, with support from the National Institutes of Health. The sleeve-like device features four pneumatic muscles, from the shoulder to the wrist, that help the real arm move. As the patient gets stronger over time, the robotic muscles gradually back off.The device is still in the prototype stage, but if it proves successful, it could be a lot cheaper than long-term, one-on-one physical therapy.This resource also includes a text description of the research and links for further inquiry.
