Science Mystery, Part II: What Tape Lift Reveals

The police investigators collected material from the carpet by tape lift. The next pages in your folder include photographs of the microscope analysis of the materials in the carpet. By determining what was found, you may have more clues to solve the mystery of who kidnapped Mr. Body and stole his painting.

Hair or Grass? (photo from CSIRO)



Click here to see how we determined what fibers the first sample were

and whether the second sample was dog hair or grass.

Don't forget to write the clues on your worksheet.

If you would like to do the experiments next week yourself, we will be working with chromotography. You will need some white coffee filters or thick paper towels, like Viva, some pencils or straws, tape and an assortment of ink pens and markers with brown ink. A set of food coloring would be nice to play around with as well.

If you are just following along with us completing the experiments, you don't need anything.
