For many years, the Saijo Formation widely distributed in Higashi-Hiroshima has been used to observe strata in science classes. We reconsider viewpoints of observation of the Saijo Formation on the basis of its sedimentological features. The proposal of the viewpoints were discrimination of the sedimentary facies and consideration of the relation between features of strata and function of running water. We also selected an outcrop which a teacher can use as a teaching material with consideration for the viewpoints, and we proposed a learning program to observe the Saijo Formation on the outcrop. The program was carried out in a science class of an elementary school. In consequence, we found that some students achieved the object of the program.
