Congratulations on becoming a PAEMST finalist. Now what? After the grueling application process, you realize that you now have to write an addendum. Here are some tidbits to help you navigate this hectic week.
Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.
Learn a bit about the chemical reactions that occur during a lightning strike, and how you can demonstrate these reactions in your classroom.
Flash rocks, typically pieces of quartz that produce light when struck together, are an example of the complex phenomenon of triboluminescence. The green chemistry aspects for the flash rock demonstration are considered, and LEGO models illustrating quartz crystals, piezoelectric materials, and nonpiezoelectric materials are presented.
You can solve Chemical Mystery #20 if you know your chemistry...and your magic!
This is the second blog post describing a classroom activity relating seawater chemistry to oceanic shipping. Included are questions that challenge students to apply conclusions drawn from observations to making predictions.
The "Two-Faced" thionin reaction involves causing a purple solution to fade to colorless by shining light on the solution. I wondered if it could be demonstrated the color of light that caused this transition.
Some explorations and explanations regarding superconductors and the quantum levitation (also known as quantum locking) experiment.
This year so many in-person events at school have not been able to happen due to COVID restrictions. One activity that the author's science honor society students have enjoyed greatly is the Skype with a Scientist Live sessions. Students register in advance and then have the opportunity to be face to face with a scientist.
Cold weather brings about the opportunity to demonstrate glass transition temperatures of polypropylene containers.
