Set a great
example for your students by going green. Learn how to
adapt your lab and activities for minimal environmental
impact, and consider using the summer to reorganize and
restock your chemical storeroom for green chemistry.
We’ll even give you a hand by waiving the hazmat fee

Need an
easy, inexpensive way to strain water from field
collection containers or an aquarium? Here’s how to do
it.
-
Cut a piece of cheesecloth slightly larger than the
opening of your lab sink.
- Place the cheesecloth over the sink and tape it securely
at the edges.
- Pour the water through the cheesecloth, which will block
any detritus and prevent it from clogging your sink.
- Discard the cheesecloth and detritus.
