KWIPPED is a highly efficient, no-cost resource for chemistry teachers looking to rent equipment for projects. If you need to source equipment that is too expensive to buy, KWIPPED.com is a great way to find short or long-term rentals that will fit your budget.
This is a series of experiments, PhET Interactive Simulation activities, and clicker questions to relate macroscopic and molecular representations of homogenenous solutions. Graphing skills are also used.
A measured value has little or no true meaning and thus, it is useless, unless the figures (digits) in that value were deemed to be significant and the significant figures were properly determined and reported. Deciding the appropriate number of significant figures for the reporting of numerical data is not an obvious or easy task.
Poisons are among the favorite weapons of mystery writers, if not murderers. Guns may be quicker, but poisons have a cachet that you really can't beat. On the other hand, murder by poison has become increasingly dangerous - to the perpetrator!
