Chemistry textbooks report a wealth of numerical data to identify periodic trends in the properties of elements, but what do all the numbers mean? In Plotting Trends: A Periodic Table Activity—ChemTopic™ Lab Activity, use microscale reaction plates and straws of different lengths to construct three-dimensional bar-type charts of the physical properties of the elements and clearly reveal the meaning of periodic trends. Available as part of The Periodic Table—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
