Mrs. Wachholz's Class Information
Dearborn Public Schools
Today students received their fingerprint study guide for their test this Friday. A copy can be found here: Fingerprint Test Study Guide
We also looked at a case study of Brandon Mayfield, who was falsely accused of a bombing using a fingerprint. Students were asked to find the claim, evidence, and reasoning given in the article. A copy can be found here: case_study_brandon_mayfield
Try this for extra practice…I’ll check it if you want me to!
Check out this online practice test below…can you answer these?

Students today used superglue and iodine to visual fingerprints in the chemistry lab.
Student groups ‘presented’ their fingerprint matches (with CER) to the class (aka the jury). We constructively criticized their evidence and reasoning as related to the claim that fingerprint ___ matched fingerprint ___.
Monday we will be in the lab, superglue fuming and iodine fuming for fingerprints.
There is a test this week, probably Thursday or Friday. Students will be receiving a study guide.
Just an FYI that there is a fingerprint test next week. Students will be receiving a study guide, but they can start studying now by looking over their guided notes and the powerpoint on this blog.
For fingerprint practice, they can also try these ‘games’…

Fingerprint matching activity with CER
Today we did a group activity with fingerprint matching and students had to substantiate their matches using the CER (Claim, Evidence, Reasoning) template.
Today we dusted for fingerprints in class. Here is the powerpoint directions that went along with the lab.
For the past 2 days we have been working on a data collection and graphing activity involving fingerprints. Students analyzed their own prints, collected class data, and then all of the forensic science class’ data. They have compiled them into data tables, bar graphs, and pie charts. The assignment is due THURSDAY. No more time in class will be given to work on this.
Today in class we started guided notes on fingerprints. Students finished rolling their prints in class if they didn’t finish yesterday. We will be using the notes and prints to help in fingerprint identification.
