Blood Typing Lab
Blood Typing LAB powerpoint
Today in lab we used our knowledge of antigens, antibodies, and agglutination to determine whether someone committed a crime.
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
More fingerprint practice
Try this for extra practice…I’ll check it if you want me to!
Fingerprint Test on Thursday!
Check out this online practice test below…can you answer these?

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’…
