A Mystery---Whodunnit????? Part 2

Student fingerprinting

Academic Objectives:

Mysteries allow students to read and think. They will use deductive reasoning and research skills to solve a mystery. They become enthused about plot development, character analysis, clues, and gathering of evidence and possible solutions. In this particular lesson, the students will be able to:

· Expand reading by looking for particular elements in the story

· Analyze clues

· Make a prediction, based on the assessment of the clues

· Make an assessment of your type of fingerprint

Technological Objectives:

· Students will use Standard 1

Pre-Requisite Technology Skills:

· Open Netscape

· Find Bookmark

· Use the scroll bar

· Know how to use the cursor and mouse

· Correctly type the URL

Materials:

· Computer with internet access

· Piece of paper and pencil, if possible use the paper with the first prediction

· Student fingerprint( This will be done in class prior to the second day)

Procedures:

Prior Activities

1. Have students make a copy of their own fingerprint

2. With a pencil, color a dark patch, roughly one inch by two inches, on a piece of scratch paper

3. Press had with the pencil and cover the entire area evenly

4. The patch will serve as the “ink pad” for your fingerprints

5. Begin with the index finger and gently rub the fingertip across the graphite on the scratch paper, three times.

6. You do not need to rub your finger very hard, the print will appear more clearly with little graphite on it

7. Cut a piece of tape to cover the dark spot on your finger

8. Press the tape on your finger and watch your fingerprint appear

9. Carefully remove the tape from your finger and place it on a bland piece of paper

10. You will see a clear image of the fingerprint

11. Follow the same procedure with the other fingers

Actual Work Day Activities

· Go to Peggy Steffen’s Home Page

· Go to Bookmark at the top of the screen. If there is no established bookmark, type in the URL http://www.cyberbee.com/whodunnit//crime/html

· Log your type of fingerprint on the worksheet, with your initial prediction

· Click on back to index at the bottom of the page

· At the bottom of the page, click on foot to height

· Read the information and try to mathematically compute the size of the suspect’s foot

· At the bottom of the page, click another category

· After all four categories are reviewed

· Click again on the Crime Scene

· Review the crime scene and suspects’ profile

· Then make a determination as to who the criminal really is (Prediction #2_

· Compare your results to your first prediction

Assessment:

An accurate evaluation of the crime scene, suspects, individual profiles, fingerprint analysis, teeth impression, and foot to height computation will generate a correct response about who committed the crime.
