Apply observation and inference skills to recognize and interpret patterns and to distinguish a specific pattern from a group of similar patterns.
Apply knowledge of the properties and interactions of materials to the investigation and identification of a material sample.
1. Recognize evidence of recent human activity, and recognize evidence of animal activity in a natural outdoor setting.
2. Observe a set of footprints, and infer the direction and speed of travel.
3. Recognize that evidence found at the scene of an activity may have unique characteristics that allow an investigator to make inferences about the participants and the nature of the activity, and give examples of how specific evidence may be used.
4. Investigate evidence and link it to a possible source; e.g., by:

4. Investigate evidence and link it to a possible source; e.g., by:
- classifying footprints, tire prints and soil samples from a variety of locations
- analyzing the ink from different pens, using paper chromatography
- analyzing handwriting samples to identify the handwriting of a specific person
- comparing samples of fabric
- classifying fingerprints collected from a variety of surfaces.
