Toxicology Lab

10/29

The shrimp are hatching! Bring substances tomorrow!!!


Here's the format for the risk assessment for five household test substances you are bringing to school. "Description of risk" should include product information. "Consequences" should be possible health effects.

All of this is part of your lab report for the toxicology lab. Make sure your Introduction and Procedures are written before you start testing on Friday! 

The final lab report is due on Wednesday,  November 4th.

Offrenda projects must go up Monday. 
You can write this on the back of your prelab LD50 calculation sheet.
