KWIPPED

KWIPPED

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. 

Homogeneous Solutions using PhET Interactive Simulations and labs

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.

Time required: 

This is a combination of activities that will take several class periods or a few class periods and homework if students have computer access outside of classtime. 

Guidelines On Determining And Reporting Significant Figures In Chemical Measurements

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.
