teaching part 3

this morning when i arrived at school


we started today by "unearthing" our samples from the tobacco and sawdust mixtures we made on tuesday. the sawdust yielded some great blues but the tobacco was rather un-inspiring. the salt and ammonia was also pretty dramatic.

samples from tobacco (see top, bottom left) and sawdust (all others), both mixed with ammonia and vinegar
