Blood Typing & Fingerprint Retake
The fingerprint retake is scheduled for Tuesday after school. If students can’t stay after school, it is up to them to make other arrangements for a retake.
We have been working on a text set in relation to blood typing. Specifically the difference between antigens and antibodies and how blood type is determined. Today we watched this video clip about a ‘donuts’ analogy.
Blood!
Today we started a new unit on blood with a brainstorming activity, Give one, Get one. One common misconception is that blood is blue in your body.
We also watched a short video clip about why blood is never blue.
Fingerprint study guide
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

Students today used superglue and iodine to visual fingerprints in the chemistry lab.
Superglue Fuming for Fingerprints
Friday 10-23
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.
FINGERPRINT TEST NEXT WEEK!
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’…
