Students had to decide if 6 different substances dissolved in water. Those items were: salt, sugar, brown sugar, cinnamon, cocoa power and pepper. Before beginning the lab, students made 5 observations about each substance. By direction of the teacher, they used their sense of taste as well to observe. In 6 different cups, they combine 10 ml of a substance in 200 ml of water and stirred for 1 minute. All combinations appeared to dissolve, but upon further review, students noticed that some did not dissolve completely. In fact, there was little dissolving by the cinnamon and pepper. Student's noticed this when they poured the into the sink. This observation helped students master the concept of what is a mixture and what is not.
I hope you enjoy learning how the garden changes throughout the school year.
