Students build their own two-cell batteries. They also determine which electrolyte solution is best suited for making batteries.

This lesson plan examines the properties of elements and the periodic table. Students learn the basic definition of an element and the 18 elements that build most of the matter in the universe. The periodic table is described as one method of organization for the elements. The concepts of physical and chemical properties are also reviewed.

Students develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper. They explore what engineers can do to help reduce poor air quality.

Students build their own simple conductivity tester and explore whether given solid materials and solutions of liquids are good conductors of electricity.
