Visitors to The Dalles Farmers Market, young and old alike, were invited to take a few minutes from their shopping for fresh produce to learn a little bit about chemistry. Our ChemClub from The Dalles, Oregon, received a ChemClub Community Activities Grant to fund hands-on activities last summer and fall at our local outdoor Saturday market. Each activity related to color in some way. Our inspiration was the National Chemistry Week 2015 theme Chemistry Colors Our World.
We offered the activities once a month, from June through October, at the markets community education booth. The five activities were:
- Nano bookmarks.Visitors made bookmarks by pulling rectangles of black posterboard through a single drop of clear fingernail polish floated on the surface of a pan of water.
- Radial chromatography.Visitors decorated squares of fabric using Sharpie markers and drops of rubbing alcohol.
- Solar S’mores.Visitors made s’mores using solar ovens made out of pizza boxes. The activity highlighted the idea that white light is made up of all the colors of the rainbow.
- Chem in a Bag.Visitors looked for clues that chemistry was happening in a bag with calcium chloride, baking soda, universal indicator, and water. They observed bubbles, a color change, and a temperature change.
- Chemeleons. Visitors painted different acids and bases onto pictures of chemeleons that had been soaked in purple cabbage juice. Depending on the pH of the solution, it resulted in a different color on the paper.
Every activity began with participants getting a safety stamp. After they listened to the brief safety rules, each person got a fruit-themed rubber stamp inked on their hand. For each of our activities that a child visited, they received an entry into an end-of-market drawing for fun science toys from Educational Innovations. We had a great time, and many people got a chance to try some summer science!
The Stuttgart High School chapter in Stuttgart, Arkansas celebrated National Chemistry Week with a wow! The AP chemistry students created a life-size periodic table of cupcakes that was enjoyed the entire week. The students also celebrated NCW at the local elementary school in Stuttgart by presenting 20 minutes of chemical demonstrations to each of the six 3rd grade classes. The students wowed the 3rd graders with different demos they worked on. The ChemClub students finished each session with a big finale of elephant’s toothpaste in a carved pumpkin. This turned out to be everyone’s favorite! Continue reading “A BIG NCW Celebration!”
This year’s National Chemistry Week (NCW) crime-based theme of “Solving Mysteries Through Chemistry” captured everyone’s interest! Our ChemClub is part of Prince of Peace, a K through 12 Catholic school on the Mississippi River, in Clinton, Iowa. With all grades located in the same building, the elementary students were able to come to the science lab for NCW. It was a chance for them to wear goggles and be crime detectives. They did tests with fiber, fingerprints, and blood. My students discovered that they like teaching!
ACS recently developed a web seminar that took place September 15, 2016 on the NSTA Learning Center. The presenters were Erica Jacobsen, a chemical education consultant who develops materials for the American Chemical Society and Rachel Murillo, teacher of forensic science and anatomy/physiology at McBride High School in Long Beach, California.
This web seminar is in support of this years celebration of National Chemistry Week (NCW) celebration and its theme of Solving Mysteries Through Chemistry. NCW is an annual event that connects American Chemical Society (ACS) members with their community, schools, and others to share the importance of chemistry in everyday life.
The co-presenters shared resources useful for NCW, for integrating forensics into classroom curriculum, and for informal presentations to share science. ChemClub advisors will find ready-to-use demonstrations, lab investigations, videos, background information, and more. Although the resources presented focused on the middle school and high school levels, many can be adapted to earlier grade levels.
