ALEX Lesson Plans Subject: Science (8 - 12) Title: Mentos, Soda, and Nucleation Description: In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students will then work in groups to determine what their hypothesis is about what is happening and why. The students will be given a chance to debate with other students about why their hypothesis is correct. This lesson could be used in eighth grade physical science, physical science, chemistry, and/or physics.Subject: Mathematics (9 - 12), or Science (9 - 12) Title: The Composition of Seawater Description: This lesson develops student understanding of ocean water as a true solution. It demonstrates the differences of salinity and "salt" water. This lesson prepares the student to be able to apply the concepts of temperature, density, and layering of the oceans before conducting a lab dealing with these variables.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: Science (9 - 12) Title: Separation of a Mixture Description: Students will use their knowledge of physical properties to separate a mixture of four ingredients. The students are required to design their own laboratory procedure for separating the mixture. The separation process itself encourages mastery of several laboratory techniques.Subject: Information Literacy (K - 12), or Science (9 - 12), or Technology Education (9 - 12) Title: Qualitative Analysis Project Description: Students, working in groups, will identify four unknown substances using analysis procedures practiced in the lab throughout the school year. They will collect data, research the unknown substances, and report findings in a slideshow presentation and web page, and collect an industry brochure.
