Students should ask each person to send to them a small sample of the soil that is common in their area. Students can compare the soil samples from around the country and the globe. Create a postage stamp or a post card. The students must research that country and design a postage stamp to be used by its citizens. The stamp might have on it a physical feature, person, or landmark that the country is noted for.
Students present their stamps to the class, explaining why they chose to use the image they used.
On one side they draw an image representative of a place. On the other side they write a message that provides readers with several clues about the place. Post students' cards on a bulletin board. Number each card. Give students a week to read all the cards on their own and to jot down their best guesses as to the place.
