Evidence and Investigation

Specific Outcomes:

1. I can recognize evidence of recent human activity, and recognize evidence of animal activity in a natural outdoor setting.


 

2. I can observe a set of footprints, and infer the direction and speed of travel.

 

3. I can 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. I can 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.

Footprints Experiment

Through investigation, we discovered that the distance between our walking stride is smaller than our running stride. In other words, when we walk, our footsteps are closer together. The depth of our footprints are also deeper when running than walking.

Footprints and Tracks

Through observation, we were able to determine the order of events when looking at tire tracks and footprints.

Analyzing Handwriting

Characteristics to look for:

  • Form of the letters (loops, slant, how the I's are dotted, how the T's are crossed).

  • Line thickness/ thinness as well as how hard the writing utensil has been pressed on the writing surface.

  • Arrangement (spacing, letter size, formatting, how letters are joined, punctuation).

  • Content (spelling, punctuation, phrasing, grammar, style of writing, word choices).
