Apples rot and turn brown because they take in oxygen and give off carbon dioxide. If apples are stored in cool temperatures, they will rot slower than they would in room temperature. Other conditions such as humidity, and the storage atmosphere also effect how quickly apples rot.
Apples to Oregon, written by Oregon author Deborah Hopkinson, is a delightful tall tale containing the best elements of a good “whopper." After reading the book, students make “growing” bracelets and learn about the basic elements plants really need to grow and thrive.

Pumpkins are a great manipulative for math and science exploration. These activities are ideal to follow up field trips and make the most of the natural connections between pumpkins and math and science.
While pumpkins are called vegetables, they are actually fruits. Technically, a fruit is the edible fleshy part of the plant that surrounds the seeds. In this activity students investigate the insides of these fruits, what the cavities look like, how seeds are attached at the ribs, and the number of seeds in pumpkins of different sizes.
