LD50 (Toxicology)

This lesson introduces students to a basic toxicological analysis, LD50 (or ED50). The range of concentrations tested will require the use of a logarithmic scale in the resulting graph.

DOCUMENT LINK: This link allows students to make a copy of the "LD50 (Toxicology)Activity" Google document/student worksheet. This document/worksheet must be submitted using the Google Form below (link also included on the "LD50 (Toxicology) Activity" document/worksheet.

The video below provides instructions for manipulating the dataset and graphing using a logarithmic scale. Be sure to include the resulting graph in the appropriate section of the "LD50 (Toxicology) Activity" document before it is submitted using the Google form above.

For 2022 Students, the spreadsheet that you will create should only include columns with "Simple Green Concentration" and "Brine Shrimp % Mortality" so, begin watching the video at 4:30....
