You probably know what happens when you place dry ice in water. Do you know what happens when dry ice is placed in acetone or glycerin? Read this and find out!
Last month, I shared about a new PD opportunity I had the privilege of participating in called Gizmos. You can read about it here. After Thanksgiving break, my Chemistry 1 and Honors Chemistry 1 classes began our Chemical Reactions unit.
Have you ever wondered where the cloud comes from when dry ice is placed in water? If you think the answer is “atmospheric water vapor”, be sure to read this post because experimental evidence suggests that this explanation is wrong.
Science is cool. It allows us to step back and reason why things are the way they are. Most importantly it fuels us to keep questioning why. Asking why is an important aspect of learning, and is a huge part of the way classrooms run, on average a teacher will ask 300-400 questions just in a day (Vogler 2008)! However, what happens when a student does not have the correct answer to a question? Are they deemed wrong? Is it a misconception that we must fix?
Addition of a white solid to a green solution causes the solution to separate into some truly beautiful colors...
After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.
