What happened to my room?
Each year the students make a molecular and brochure of their favorite molecule. We then have a voting period over two days where current and former students as well as teachers vote on the models. The votes are entered on a Google form accessed using any internet device. Congratulations go out to all my students for producing these wonderful representations.
This years winners (by popular vote) are as follows...
|First Place Period G and An Overall Winner|
