Chemists celebrate Earth Day: volunteers?

This year, Chemists celebrate Earth Day on April 20, 10 am to 4 pm, at the St Louis Science Center.

Volunteers are needed to staff tables of activities:

• Kids and Chemistry is seeking volunteers for chemistry outreach fun. No experience necessary: tables will be set up and each will have a leader for instruction. Contact Sheryl Loux at sjloux@gmail.com to volunteer; a commitment of at least 2 hours would be appreciated. Parking will be free to volunteers and entrance is always free.
• Greg Wall is also looking for volunteers for other activities around the theme: Rethink Recycling: It’s Easy to be Green. Contact him at gwall37@msn.com.
