Abstract	Nanochemistry is an important aspect of modern chemical science. Though few educational institutions teach nanochemistry as a formal course, general exposure of students to nanoscience is yet important. Thus, we present a nanochemical activity that could be used as part of many chemistry courses or laboratories based on ChemToy2. This activity is judged to be fun and enjoyable by students and is conducted over a one-week observation period. During this time, gold and silver nanochemistry results in 45 fundamental states or changes in the five observed solutions. Possible observations include a myriad of colors centered on purples and greens, photochemistry, the common states of matter, the Tyndall effect, surface-wetting phenomena, detergent action, gradients, and discontinuity. Each student's power of observation can be scored at the end of the observation period, and discussions and further activities based upon their findings can proceed. We provide nanochemical results on ChemToy2 to support these activities; data include localized surface plasmon resonance (LSPR), optical light scattering, dynamic light scattering (DLS), nanoparticle-synthesis growth maps, and results of testing by 114 undergraduate students.
