18-Wheeler Chemistry

Some truckers haul hazardous materials and chemicals, and hazardous material codes are posted on these trucks to alert emergency service crews to the type of chemical being hauled.  In the event of an accidental spill, crews can then take the necessary steps to protect people and the environment.

Your carschooler can use a code chart to determine what chemicals the trucks they see on the road are hauling.  Then, using a Periodic Table of Elements, they can look up the chemical to learn its symbol, atomic weight, and number.

This activity is a great way to introduce the importance of chemistry in everyday life!
