Chemapalooza

It was CHEMAPALOOZA on March 16, 2017, in Lake Charles, Louisiana. Barbe High School ChemClub and AP Chemistry students visited their feeder school, S.J. Welsh, to perform multiple experiments and demonstrations with every eighth grade science class. Approximately 400 eighth grade students had the opportunity to observe demonstrations like the Blue Bottle, Dry Ice/Density of Gases, and relighting a candle using the trail it produces after you blow it out. Barbe High School students performed all demonstrations and explained the science concepts behind each one.

In addition to the demonstrations, Barbe students led the middle school students in three hands-on lab experiments. Students rotated in 15-minute intervals between three stations that were designated Maroon, Blue, and Grey, from the school colors. Each station had one hands-on lab investigation and one demonstration. In the hands-on investigations, students learned to pipet using a pipet pump during the Vitamin C Iodine Clock experiment (a green chemistry version) and measured the rate of reaction due to changes in concentration. They learned to take electronic temperature readings using a Vernier Lab Quest for the Thermodynamics lab investigation, in which they determined if the enthalpy of solvation was exothermic or endothermic. Lastly, they performed a chemical reaction to form a gas and a precipitate, to observe some typical signs of a chemical reaction, while also learning how to tare and weigh a reactant and how to read a graduated cylinder’s meniscus.

Each eighth grader was given a cardstock Lab Report to record their data and observations from each station. Participation by all students was phenomenal. CHEMAPALOOZA was a great success and Barbe Students have been invited back next year. We hope to make CHEMAPALOOZA an annual event going forward.

Family Science Night

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.
