Objectives
- To enhance students' knowledge of the vast possibilities that lie
within a kernel of corn through independent observations of visual materials,
particularly scientific photographs.
- To teach students the principles of using visual materials as sources
of information.
Activity Summary
Students will examine a photomicrograph of a kernel of corn. Clues to
interpretation of the photograph will lead them to discover that within
the common corn kernel lays a whole world unseen by the naked eye. The
Story of Corn Scavenger Hunt Activity will lead students to investigate
the unique properties of corn and the many uses of corn byproducts. The
Webliography also provides a number of online
resources students will find useful and interesting when investigating
the many uses of corn.
Extension Activity
The science of photomicrographs isn't a recent development. Soon after
photographic technology was developed, people were eager to apply this
new device to the world of the microscopic. Taking
a Photomicrograph .... in 1904 provides a look at a most interesting
camera designed to take microscopic photographs-in 1904! Since that time,
photo technology has come a long way.
Students will find the microscopic world fascinating and interesting.
They may even want to develop their own Mystery Photo Activity. Use the
following steps to prepare your students for this experience:
- Search for the word "photomicrograph" using a common search
engine.
- Have students select and print an image from one of the collections.
- After cutting and trimming the image, mount it on a piece of cardstock.
- Using 3x5 cards, have students write two Mystery Photo Clues. Tape
the clue cards face down to the bottom border of the cardstock.
- On the reverse side of the cardstock, have students identify the
object and add any appropriate background information to help the viewer
interpret the image.
- Display the images on a Mystery Photo classroom bulletin board.
