Atoms: Atom Models
For a couple of years, I have assigned Mr. Niven's Atom Project to my students. I have typed up my own instructions (as some of his statements wouldn't make sense to my students), but required the same elements as Mr. Niven. I've greatly enjoyed the resulting projects and appreciate the "able to hang from the ceiling" requirement. Getting them to hang is a bit of a chore, but once they're up, they're enjoyable to look at and they don't take up precious space on lab tables or elsewhere.
Once the projects have been turned in, I like to have students take turns sharing the information they found. To keep other students paying attention, I have them take notes of the highlights. Then, after everyone has presented, they are given a brief quiz ("This element is the most abundant in the universe.") during which they can use their notes. For students who have paid attention, it should be an easy way to boost their grade.
FYI The models pictured here were created by my students. And, with regard to the second model, it did have the appropriate number of electrons... they started to fall off while being stored.
