Chemical Mystery #5: How to burn water
The video displays a neat trick you can do for your students. What do you suppose is the secret behind this trick? Hint: It has to do with chemistry!

Yesterday I posted about Day 1 of the Chemistry Camp
My goal with this summer camp was to expose students to the chemistry of things around us - plants, food, batteries, fuel, etc. Fortunately, by studying plant pigments and photosynthesis, students were able to learn about and utilize common lab techniques.
Oh summertime! My non-teacher friends and neighbors like to point out that it must be great having summers off from work. I try to explain that I’m still working although it’s really nice having a break from the students. And I know that a lot of colleagues in my PLN on Twitter are enjoying their break from students too while still spending some time working on upcoming challenges and curriculum designs.

In a previous blog post, I shared my thoughts about the importance of science teachers (and all teachers, really) supporting their claims about lesson efficacy with evidence. While this doesn’t always need to be a formal research study, it can often be valuable to publish findings that will be helpful to other science teachers.
If videos are the method of choice for my students’ free time learning, then why do they sometimes struggle to hear and make sense of the chemistry content in the short teaching videos created by their teacher?
n teaching we regularly change our class structures and routines and we implement new “interventions” in hopes of changing classroom dynamics or reaching more students. I know that most of the time I make these decisions based upon anecdotal evidence, perhaps after glancing at a handful of exit tickets from my students or based upon how I “felt” the class went. Recently, though, I’m finding myself a little more hesitant when making a claim about my class. I require that my students support their claims with evidence, so why wouldn’t I also support mine with evidence?
I have been involved in several types of community outreach projects to promote science education and chemistry. One of the best was a biannual event I worked on with teachers from each elementary school in our district and from our middle school. It was a Science Extravaganza.
The “Elephant Toothpaste” experiment is a very popular, albeit messy chemistry demonstration. To carry out this experiment, place a 250 mL graduated cylinder on something that you wouldn’t mind getting messy.
