Hi all! I am currently a pre-service teacher teaching a mini unit on subatomic particles. With regards to the number of protons, neutrons, and electrons, my students struggled with this concept. I tried using M&M's in order for differentiating the three particles. Does anyone have any additional activities that you found beneficial to your students? I would love any feedback that you all have, thanks!

Hi Michael,

I found an article with an activity that may be of help! I'm not sure the age of your students, so you may have to change a few things to meet the specific needs of your class, but this article describes how a teacher had students create their own models of an atom. Then, they presented to the class and the models hung around the room for the rest of the year for review. Let me know what you think!

Does anyone else have any ideas to help?

So sorry, Mike! I included a slash at the end, and that made the link unreachable. My apologies!
