It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
Science Practice: Constructing Explanations and Designing Solutions
The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
This activity allows for the simple and accurate determination of the heat of vaporization, ΔHvap, of water at 100°C, and ultimately the approximate strength of a hydrogen bond in boiling water, in kJ·mol–1.
Ariel Serkin shares an activity she has explored using natural acid base indicators with her food chemistry elective students.
This empowering activity provides students the opportunity to drive their own lab experience. It allows students to perform research, execute lab techniques and identify an unknown substance.
The Diet Coke and Mentos reaction is used as the basis for this hands on experiment. Students work in groups to research, test, and adapt as needed with the goal to get the highest possible geyser!
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.
You can solve Chemical Mystery #20 if you know your chemistry...and your magic!
