Water Content of Apples - Apples, like many other fruits and vegetables, contain a significant amount of water. This experiment focuses on the apple's water weight. Each student needs an apple slice. Students tie a piece of string around their slices, weigh them on a small scale, and record the weight in their learning logs. The apple slices should be hung to dry.
Students weigh the slices every several days and note the weight in their logs.
In their logs, students hypothesize why there are changes in weight. Using Microscopes - Slice an apple into very thin pieces. Put each under a microscope. Have students work in pairs and discuss the appearance of the apple slice under the microscope. Ask students to draw what they see and write down as many words as they can to describe it.
