Students should develop their own methods of testing these bars for strength. Students conduct an online search of concrete companies. The teacher should designate whether the data to be collected should be national or international. Then the students record the location of the companies on a hard copy of a map. Depending on the ability level of the students, they may wish to make a key and differentiate types of concrete.
Students then discuss plausible explanations for the company locations.
Each student then writes a paper about starting their own business. They should include what type of concrete, company location, reason for location, uses for their type of concrete etc. To better understand the formation of cement, students should have an awareness of the sequence of the formation process. The teacher can capture the graphics on the web page depicting the stages of the process. The students sequence the events either manually or by using a slide show or multi-media program.
