 March Forensic Science Lesson Plans Date Objectives Activities Standards 3/2 Mon Using microscopy, distinguish between different types of fibers. Solve a crime by comparing fiber characteristics Discuss fibers notes “Picking up the Pieces” Lab- (A lab on Fiber Analysis) : Part 1- Microscope analysis of fibers; Part 2- Behavior of fibers in flame HW: Quiz over hair and fibers on Wednesday MSCS 1: BM 1, 2 3/4 Wed Differentiate between 3 types of soils. Analyze the pH, color, and texture of different soils Operate a stereoscopic microscope Hair and Fiber Quiz (10 mins) Read through “Soil Analysis” Lab (15 mins): What is pH? Using the Vernier Interfaces and pH probes to gather data Soil Analysis Lab (50 mins)- Analyze 3 soil samples- color, particle size, pH, etc. HW: Glass Reading worksheet MSCS 1: BM 1, 2 MSCS 3: BM 1 3/6 Fri Identify the ways glass is analyzed as trace evidence Define refractive index and density Describe how bullet hole patterns in glass can solve a crime Glass as Trace Evidence (15 mins): Bullet holes in glass- determine bullet order and what side of the glass the bullet went through, Fracture Matching, Light Bulb filaments- Was the light on or off? Bullet Hole Order Lab (30 mins) Notes- PPT- glass, paint, and other trace evidence (20 mins) Demo: Refractive index water vs. glycerin (glass stirring rods) MSCS 1: BM 1, 2 MSCS 2: BM 4 3/10 Tues Define density and apply its equation to determine the mass, the volume, or the density of an object. Measure the density of different glass samples to solve a crime scene scenario Review Glass as Trace Evidence Mystery Canisters lab (30 mins) Density notes- equation, How to find mass and volume, How does density relate to trace evidence?- glass Glass Density Lab (30 mins)- Lab worksheet HW: Density problems for homework (15 mins) MSCS 1: BM 1, 2 MSCS 2: BM 4 3/12 Thurs Explain how trace evidence was key to finding and convicting a suspect in a historical case study (Atlanta Child Murders). Identify the types of trace evidence and discuss the methods used to analyze trace evidence. Atlanta Child Murders Case Study (30 mins)- Read case study; Questions: Summarize the case study, How is trace evidence involved in this case study? Trace Evidence Webquest (online Forensics lab) (45 mins) Test Review: Trace Evidence HW: Trace Evidence Test next class MSCS 6: BM 1 3/17 Tues Evaluate student knowledge of trace evidence Test (40 mins) Read “Firearms” and complete Question Sheet (20 mins)- Types of firearms, Components of a cartridge case, Definition of ballistics HW: Finish question sheet MSCS 1: BM 2 3/19 Thurs Identify the types of firearms Describe the components of a cartridge Explain ballistics and identify how it can be used to solve a crime Begin Chapter 4: Firearms- Pre-assessment (10 mins) What types of firearms are there? What is the difference between a handgun and a shoulder firearm? What is ballistics? Firearms and ballistics notes- PPT (30 mins)- Notes and Video shorts Bullet Comparison Activity (30 mins) MSCS 1: BM 1, 2 3/23 Mon List examples of different types of forces, as they pertain to ballistics Describe situations that illustrate Newton’s three laws of motion Ballistics Notes/Discussion (75 mins) Forces acting on a bullet- Internal ballistics, External ballistics, Terminal ballistics, Newton’s Laws of motion Ballistics/Physics Webquest (60 mins)- How does gravity impact a bullet? How does muzzle velocity impact a bullet? Forces acting on a bullet HW: Finish webquest for homework MSCS 2: BM 5 3/25 Wed List examples of different types of forces, as they pertain to ballistics Describe situations that illustrate Newton’s three laws of motion Use angles and trigonometry to determine missing variables in a ballistics problem Review ballistics; turn in webquest Discussion: What variables can be learned from a bullet hole embedded in a wall? (20 mins) Discuss angles and their importance in determining bullet trajectory Trigonometry- finding missing variables SOHCAHTOA (Sin, Cosine, and Tangent) Trigonometry practice problems (20 mins) Begin “Where’s the Shooter Lab” (35 mins) Use a protractor to find angles MSCS 2: BM 5 3/27 Fri Evaluate student understanding over unit List examples of different types of forces, as they pertain to ballistics Describe situations that illustrate Newton’s three laws of motion Review Ballistics and Firearms (10 mins) Firearms and Ballistics Qest (30 mins) CSI Facts vs. Fallacies MSCS 2: BM 5 MSCS 1: BM 2
