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 draw 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.
What is the pressure inside a bottle of soda pop? Read this short article to find the surprising answer to this question, and also to learn how to do an experiment to answer this question for yourself!
Liquid nitrogen is used to visualize the aerosol particles emitted while speaking, coughing, breathing, and sneezing. The ability of various masks to block these droplets was also tested.
The Ruben's Tube (also known as a Flame Tube) is a classic experiment used in physics classes. There's also a bit of chemistry to be learned while experimenting with a Ruben's Tube...
Germany issued a pair of stamps that honor two fundamentally huge accomplishments in science in 1994. The Quantum Theory and Ohm’s Law. They were really well designed stamps and very accurate in their science.
Have you heard that TERC, a nonprofit, has launched a STEM Teacher Leadership Network funded by the National Science Foundation? The online community is for aspiring or current teacher leaders, researchers and administration to improve STEM education, effect policy and discuss the changes to the future of STEM education in a collaborative online collegial network.
