ALEX Lesson Plans Subject: Mathematics (9 - 12), or Science (8 - 12) Title: Density Description: Density is the ratio of mass to volume. Density will be introduced to students by a demonstration of coke verses diet coke. The teacher will then solve density problems for the students on the board. The class will then complete a lab on the density of plastics. After lab the students will compare results. Each group will present a Powerpoint presentation of their results.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.Subject: Mathematics (7 - 12), or Technology Education (9 - 12) Title: Water Tank Creations Part I Description: In this lesson students will study the surface area and volume of three-dimensional shapes by creating a water tank comprised of these shapes. Students will work in groups of 4-5 to research water tanks, develop scale drawings and build a scale model. Teacher will evaluate the project using a rubric and students will assess one anothers cooperative skills using a rubric.
