Forensics Lab

This week we transformed our classroom into a forensics lab to test some evidence fresh in from the crime scene.  Our analysts learned about chromatography and matched ink band samples from different pens to find the culprit who wrote the ransom note in The Case of the Dognapping.  They also compared physical properties of three different mystery powders confiscated from suspects in The Case of the Crummy Cake. Students then looked at the chemical properties of the substances as they tested their reactions to water and vinegar to identify each and catch the culprit.

For math, third grade worked on more median, mode, and range. For more review students can watch this video: Mean, Median, and Mode Toads.

We also did part two of our Critical Thinking Series.  We discovered the 5 Standards of Critical Thinking (clear, relevant, fair, accurate, and logical).
