The untold story of the women who helped win World War II by separating the atomic bomb isotopes.
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
This is a program that has an electronic copy of the map for all teachers to see. The entire map is tied to standards that are a version of state, federal and or local standards. Any formative assessment can easily be graded and tied to a standard. The data can be used to break down how the kids are doing in any one standard and plan future lessons accordingly. If we need to change to meet the needs of our students, we can and should immediately. It is not perfect but is trying to maximize data collection and analysis to help teachers and students.
CRISPR and gene drive technology have the potential alter the biology of life on earth, and possibly control some of the most destructive human diseases.
Show the kids an event. Have them develop a model. Have each kid draw and write about the model and force them to ask themselves if this model can explain the event. As a teacher, first say something nice about it and then look for their misconceptions and use this as a formative assessment. Combine the individual models with others. Slowly build a larger model and constantly ask if this really explains the event.
I taught my students how to use the method of initial rates. I taught my students rate laws. However, they strugged to differentiate when to use what method. Upon further probing, they struggled to articulate why one might use one method over the other. They could parrot back some ideas ("The rate law tells you about the particles involved in the rate determining step of the reaction."), but I wasn't convinced of mastery and connections.
This is the first isotope activity I have tried where the students can look inside the model that resembled the atom and find information that reinforced what an isotope actually is. Furthermore, the quantitative data forced them to examine beliefs about different types of averages and what the numbers really mean.
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!
The American Modeling Teachers Association (AMTA) is an international, professional community comprised of over 2800 passionate, innovative, and connected educators. Members include high school and university level STEM educators, educational research professionals, as well as pre-service and retired teachers.
In this "Pick" I'll briefly describe how I use the ChemDraw iPad App for creating structures for my teaching. I also provide a link to a tutorial where I share some tips on how to get started using ChemDraw on your iPad.
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.
