They are challenged to find the most effective way to heat a house with solar energy. First, students test the effect of house orientation on solar heating. Later, students conduct an investigation to find out the effect of interior color on heating the air in their model house. Several more investigations are conducted, and students collect and graph all of their data. Students are then challenged to use as many technologies as necessary to get a solar house as hot as possible and to keep it warm as long as possible.
Some programs stay permanently in the machine but most are coded on disks.
Computers can be programmed to store, retrieve, and perform operations on information. These operations include mathematical calculations, word processing, diagram drawing, and the modeling of complex events. Mistakes can occur when people enter programs or data into a computer. Computers themselves can make errors in information processing because of defects in their hardware or software. Tools, such as thermometers and x-ray machines, provide us clues about what is happening inside the body.
