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?
Nora Walsh outlines the interactive notebook pages she uses for her unit on Solutions. All of the documents and foldables are available for download.
The use of multiple representations helps to characterize students' understandings and their misconceptions. Stacey Lowery Bretz shared multiple resources and strategies for using them in her ChemEd X Talk. The recording is available here!
Many chemistry teachers use models and diagrams to help students describe how matter behaves at the particle level. On April 14, 2022, Doug Ragan explained how he uses colored magnets in his classroom to represent things such as subatomic particles, states of matter, balancing chemical equations, types of bonding, molecular geometry and much more. View a recording of his presentation and access materials he uses.
Chad Husting uses a few simple gas law experiments to introduce his students to the particulate level of chemistry.
After teaching the concepts and calculations for acid and base strength, concentration, percent ionization, and pH I noticed many of my students were struggling to make meaningful connections between these calculations.This lesson was created to strengthen the understanding of the relationships between these concepts and skills.
Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.
This activity aims to boost students’ confidence in representing the atomic world. It also aims to educate both students and the general public about the “chemicals” found in everyday objects.
Are you having a hard time describing 3-D drawings or or showing motion of particles in your digital assignments? GIFs can help!
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
