Formative assessment will be critical as the students work their way through the equations and compare them. Students to scaffold one another in small or large groups as needed. Lesson will be taught to the class as a whole with plenty of opportunity for.Students will hand in a paper explaining narratively (in plain language) what both the Seagar and Drake equations are, the formulae, and the numerical values they arrived upon, accompanied by sound reasons.Students will determine a plausible value for each of the estimates, and they must have a reliable source and/or sound reasoning they can articulate for their values/estimates.Students will use computers to research further about both Seagar and Drake equations, especially where the class seems divided or unclear about what reasonable values of variables might be.They will now begin thinking about what numbers/estimates might be reasonably used for each of the variables in the equations. At this point, the class will move away from analyzing how the equations work and are similar/different. Teacher will go through each variable found in the equations and write them down on the whiteboard.Teacher will probe class to answer why we use these equations and how they are similar and different.Teacher will read aloud sticky notes under each header on board.Teacher will ask students about what they discovered about the two equations.After reading and highlighting these similarities and differences students will write out what they have found and post them under proper header on the whiteboard.After students have had some time to get used to the task, the teacher will distribute sticky notes for students to record similarities and differences of each of the equations.Give them plenty of processing time-this sort of comparison of complex mathematical equations may be novel and uncomfortable. Students can work independently or in small groups to initially brainstorm their ideas about similarities and differences. Teacher will split whiteboard into similarities and differences.Students will receive both handouts and read them.Students will be able to distinguish between the Seagar and Drake Equations, through scientific evidence, mathematical calculations, and literacy. In this lesson, students will compare the Seagar and Drake Equations through scientific background, as well as mathematical calculations.
