If I were to teach to chemistry I think these activities listed would be enjoyable before the winter break. One of the links leads to a word document in which the Chemis-tree activity is turned into a project. This project in particular uses ideas we've implemented in our classroom such as allowing the students to choose what will be on their ornament that pertains to chemistry(i.e. model molecule, famous experiment, famous chemist, etc) There are also guidelines that emphasize observations.
