Lego Stoichiometry

In this Activity, students use building-block car kits to explore stoichiometry in a concrete manner. They determine the relationship between the number and mass of each required car component (the pieces in the kit) and the mass of the final product (the completed car). This Activity works well as either an introduction or review of stoichiometry.

Measurements for a Rainy Day

In this Activity, students collect data outdoors on a rainy day using plates and paper towels and use the information to calculate the rate of rainfall. This Activity reinforces ideas about density, mass, volume, area, length, and units.
