How does the blue to white color change occur in the foam of Scrubbing Bubbles or KABOOM Brand cleaners? Watch this video and find out.
During the first week of school, I welcome my students to the What Not To Do Lab. The PDF is available for free at the Laboratory Safety Institute website. I use the cartoon activity to review their Safety Contract handout from the night before (I use the one from FLINN Scientific). With more than 30 safety violations shown, the cartoon serves as a great ice breaker as I have each student introduce themselves and then list a safety infraction being shown on the cartoon.
This can be completed easily within a 50 min class period.
Welcome back y'all! The beginning of the year is so exciting! I feel energized and look forward to meeting my new students. My classroom is neat and tidy, even my lab is organized and clean. And then, it begins. We do a lab, the students get to experience chemistry through some hands-on work, and I need to see what they have learned. Oh, the lab reports!
CLEAPSS is a subscription service, but our YouTube Channnel is an open source. The videos are designed for teachers and technicians in schools. They may just give you ideas. I have just put one up about electrostatics and the effect of magnets on water and oxygen. In a couple of weeks I hope to have a sequel showing the effect of magnets on precipitates and complexes.
Get ready for a splash of color during this year’s National Chemistry Week (NCW) celebration, October 18–24, 2015. The theme “Chemistry Colors Our World!” gives a chance to explore the chemistry of dyes, pigments, and light. An upcoming free webinar can get you started with resources.
PBS has a wonderful new mini-series titled, "The Mystery of Matter: Search for the Elements". At the time of this post, the series is freely available to stream through your local PBS station. (The series is also available for purchase.) The series is broken into three episodes which track the evolution of Chemistry in different time periods through the eyes of seven scientists.
