Enter the substances in the table. Make sure we can edit the table and copy the table. If not, we may need to do this in an embedded file. Test substances in class (closed toed shoes, long pants/skirts are required) and complete the table. Use table/test results to develop a dichotomous key. You won't have time to perform every test on every powder. Based on your initial observation, you need to be able to narrow down the possible powders and only perform the necessary tests on each powder.
