Summary:
Today was the last day of our study of elements, compounds, and mixtures. Students rotated through seven different stations and observed seven different substances: washing soda, gallium, grass, sugar, wood, charcoal, and the blue bottle.

At each station, they attempted to classify the substance as an element, a compound, or a mixture. Through observation, or consulting their periodic table, or even reading the box or bottle, most groups were able to classify the majority of the substances. At the end of class we went over the answers (see PowerPoint below).
