  1. INVESTIGATION Mrs. R. Crist

  2. INVESTIGATION ☑ recognize evidence of human activity in an outdoor setting ☑ recognize evidence of animal activity in an outdoor setting ☑ infer the direction and speed of travel of a set of footprints ☑ recognize characteristics of evidence and make inferences ☑ investigate evidence and link it to a possible source: ☑ classify footprints, tire prints, and soil samples ☑ analyze the ink using chromatography ☑ analyze handwriting samples to identify handwriting ☑ compare samples of fabric ☑ classify fingerprints Mrs. R. Crist

  3. ESSENTIAL QUESTION What sources are collected for evidence? Mrs. R. Crist

  4. ESSENTIAL UNDERSTANDING Evidence is collected from a variety of sources. Mrs. R. Crist

  5. ESSENTIAL QUESTION What is important in analyzing evidence? Mrs. R. Crist

  7. ☑ recognize evidence of human activity in an outdoor setting • Guess & Collect: • Tire tracks • Footprints • Fabric • Litter • Observe & Infer: • activities • participants Mrs. R. Crist

  8. ☑ recognize evidence of animal activity in an outdoor setting • Guess & Collect: • Footprints • feathers • Fur • Scat • Evidence of feeding • Observe & Infer: • activities • participants Mrs. R. Crist

  9. ☑ infer the direction and speed of travel of footprints • Track/Trace: • Human prints • running • Walking • Track/Trace: • Animal prints • Walking • running Mrs. R. Crist

  10. ☑ recognize characteristics of evidence and make inferences • Describe: • Shoe Sort • types • size • Describe: • Animal prints • pads • size • claws • # of paws, hooves Mrs. R. Crist

  11. ☑ recognize characteristics of evidence and make inferences • Describe: • Direction of Travel • jumping • All feet are close together and there is a great distance between the tracks • Walking • No bunching of feet, a short distance between each print • running • All feet are distinct, a large distance between the prints Mrs. R. Crist

  12. ☑ recognize characteristics of evidence and make inferences • Humans • Walking: • Shallow print • Clear and uniform • Shorter stride • Running: • deeper print • deeper toe (pushing off) or deeper heel (landing) • some smudging due to speed • longer stride due to speed Mrs. R. Crist

  13. ☑ recognize characteristics of evidence and make inferences • Describe: • classmates • Choose 3 similar • Choose 1 2 describe • Have the 3 guess which one you chose • Wanted: • Personal profile • Photo • description Mrs. R. Crist

  14. ☑ investigate evidence and link it to a possible source: tire prints and soil samples • Describe: • tire tracks • tread • size • source • Describe: • soil • size • density • source/location Mrs. R. Crist

  15. ☑ investigate evidence and link it to a possible source: ink & handwriting • Chromatography: • Black markers • Control variable • Independent variable • Procedures: • Graphology: • handwriting • size • slant • Other: Mrs. R. Crist

  16. ☑ investigate evidence and link it to a possible source: ink & handwriting • Graphology: • Slant: • Left: in control • Right: friendly • Straight: thinker • Pressure • Hard: agitated • mid: deals with stress • Light: flexible • Size • Tiny: intelligent • Large: confident • Huge: theatrical • Wide: friendly • Narrow: shy • Curved: friendly Mrs. R.
