I was recently reading the June 30, 2025 blog posting on the National Science Teachers Association website. 

The blog was posted by Ken Roy and the title of his blog post was "Dealing with Chemical Waste in the Science Instructional Space."

Unattended hazardous chemical waste can be unsafe, and at times, dangerous.  In Ken's blog posting, he shares 10 key factors to consider for an appropriate chemical disposal program in school.
