ALEX Lesson Plans
Subject: Mathematics (9  12), or Science (9  12) Title: Float or Sink?
Description: Students will define density and use the density formula to determine the density, volume, and mass of various items using the correct units for each measurement.
Subject: Mathematics (9  12), or Science (9  12) Title: Transform Me!  Types of Energy
Description: Students will understand the law of conservation of energy and the transformation of energy from one type to another.
Subject: Mathematics (9  12), or Science (8  12), or Technology Education (6  8) Title: Bloodstain Pattern Doesn't Lie......
Description: Students will formulate a hypothesis about the relationship (linear, direct, indirect, etc.) between the distance a drop of blood falls and the diameter of the splatter it makes. To test their hypothesis, the students will work collaboratively to make blood droplets, on paper, from different heights. After graphing droplet diameter and height using a spreadsheet program, individual students will evaluate their hypothesis. Students will use their graphed data to: 1) write an equation for the mathematical relationship of droplet diameter and height. 2) interpolate the height from which a blood droplet made by someone else was dropped. The students will compare data from different groups to determine possible sources for differences.
Subject: Science (9  12), or Transportation, Distribution, and Logistics (9  12) Title: Automotive Brake Serviceinspecting and Machining a Disc Brake Rotor Off the Vehicle.
Description: The proper inspection machining or refinishing of disc brake rotors ensures quality brake repairs with little to no opportunity for returns for customer complaints. This lesson will teach inspection, measuring and machining techniques and procedures.
