Cross Curricular Connection

While this model explores the circular motion of curves to be used in a physics class, there are many connections to other disciplines that can be taught along side this module, making it a good interdisciplinary unit.

Math

A geometry lesson using Geometer Sketchpad begins by looking at the properties of the chords of a circle. Another geometry concept is that the perpendicular of a chord in a circle will pass through the center of a circle. Since two lines intersect in a point, if these two lines are perpendicular bisectors to two different chords of the same circle, the point where they intersect will be the center of the circle. Once you locate the center of the circle, valuable information can be determined such as the radius, diameter, area and circumference. The center can be used to make central angles, opening the door to more information about the circle. Measurements of the arc of the circle will then lead us into a study of degree and radian conversions and trigonometry.

The lesson that teaches the use of Scion Image reviews the concepts of ratio and proportion and measurement conversions from feet to inches using both fractions and decimals.

Speech and English

To make this unit interdisciplinary, the English teacher can help the students write their reports for the physics module. The English classes could also read articles and do research on books dealing with public transportation, Department of Transportation, automobiles, and the trucking industry. The speech or English teacher could help the students prepare their multimedia presentations.

Social Studies

The social studies teacher could study the historical aspects of the highway system, public transportation, accidents on roadways, the trucking industry, history of motor vehicles, the oil and gas industry and its effects on trucking and fuel cost.

Chemistry

The chemistry teacher can explore the effects of chemical spills and hazardous waste on the environment.
