Tanque Verde ChemClub Celebrates Earth Day

Science is amazing!

ChemClub members at Tanque Verde High School (TVHS) in Tucson, AZ, recently participated in the 2014 Tucson Earth Day Festival. The festival is an annual event full of opportunities to showcase local science and environmental programs. We joined forces with our Southern Arizona ACS Local Section to prepare hands-on activities and displays for the public to highlight Chemists Celebrate Earth Day (CCED).

TVHS students brought several demonstrations related to the current CCED theme, “Wonders of Water,” to share. Groups of TVHS students rotated through the day to teach visitors about different properties of water. Our hands-on activities explored the cohesive and adhesive properties of water, changes in surface tension, and conductivity of water. We also collaborated to prepare a water filtration demo to display at the ACS booth. The greatest challenge for this outreach activity was the outdoor location—since the festival takes place in the park, we needed to battle the elements—sun and wind!

For many of our visitors it was a chance to become a scientist for a day, wear goggles, use pipets and a conductivity meter, perhaps for the first time ever!

  1. Congratulations to the ChemClub and Dr. Zreda for representing their school, their club, and themselves so wonderfully well at the 2014 Tucson Earth Day Festival. Looks like the young scientists were captivated by the ChemClub’s participatory demonstrations.
