Our ACS ChemClub (Buena Science League) at Buena High School in Ventura, California, has developed an exciting outreach program for local elementary and middle schools. We travel to the local middle schools and spend the day presenting demonstrations to their science classes. In a day, we typically see six classes, with about thirty students per class. Depending on how we travel to the middle school, we take seven to twelve Science League student demonstrators. We also host an annual Science Show for elementary students in our large auditorium, usually presenting three 40 to 45 minute shows to an audience of 200 students per show.
We also host themed Family Science Nights each quarter for elementary and middle school families. We arrange demonstrations for viewing and hands-on activities for participation. We try to choose demonstrations and activities that relate to the chosen theme. Fourth through eighth grade students attend for an hour and a half in the early evening. About 30 students came to the last one, with a superhero theme. We have about 15 students participating from the high school, and they are pretty committed to the events. Their responsibilities are to learn how to perform specific demonstrations safely and to explain the underlying science.
The 2015-2016 school year was a busy one for the homeschoolers of Union ChemClub in Union, New Jersey. Our monthly ChemClub meetings brought opportunities to learn chemistry while having fun. Some of the experiments we covered were chromatography, iodine clock reactions, double replacement reactions, making “elephant toothpaste” and a “sweet” sugar density column. One of our local universities allowed us to borrow a Milton Roy 20D Spectrophotometer for oneof our labs.
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!
Halloween Chemistry and Mole Day are rising to the top of the most visited list on the ACS ChemClub Activities page. It must be October! If you haven’t visited the page before, ChemClubs offers a new Activity of the Month, well… every month. Each Activity collection focuses on a particular theme. For example, the latest topic is Makeup, Tattoos, and Hair. Each theme has a curated list of links. We comb the web for experiments, demonstrations, informational sites, and videos related to the month’s theme, then categorize and collect them with brief descriptions. ChemClubs also archives past Activity of the Month pages. The Halloween Chemistry and Mole Day pages are typically among the most popular during this time of year.
Mole Day may be over for the year, but bookmark the page for ideas for 2017. There’s still time to use the Halloween collection to get ideas for adding some creepy chemistry and spooky science to your day.
Some things you’ll find on the Halloween Chemistry Activity of the Month page:
- Looking to make chemistry your Halloween wardrobe of choice? Take a look at the Costumes tab for ideas on masquerading as your favorite element or compound.
- One link in the Body Parts tab suggests giving a classic demonstration a Halloween twist. You could probably dig up the materials at your house right now. Fill a plastic zip-seal bag with water, add red food coloring, and seal to create a bag of blood. Then, stab through the bag with skewers or sharpened pencils. The bag won’t leak due to the structure of the polymers that make up the bag.
- Dry ice is indispensable for a bubbling cauldron effect. But, it can also be used to create a crystal ball filled with a swirling fog of the future. Look for the Boo Bubbles link in the Dry Ice tab. I’ve used the homemade container featured in the Sick Science! video at the link with kid-crowd-pleasing results.
