  • The purpose of this study is to provide implications for developing science textbooks and curriculum. The textbooks of elementary and secondary school Science were analyzed for their animal-related learning contents. Among learning materials, 165 kinds of animals were presented in Science of elementary school textbooks (37 kinds in Inquiry life, 162 kinds in Science), 167 kinds in Science of middle school, 486 kinds of high school (172 kinds in Science of high school, 180 kinds in Biology I, 366 kinds in Biology II). There are most kinds of animals in Biology II textbooks than in other textbooks. It was appeared that animal species were diverse in order of Class Insecta, Mammalia, Aves in the elementary school Science textbooks, Mammalia, Insecta, Aves in the middle school, Mammalia, Aves, Pisces in the high school.

  • The study was attempted to scrutinize the normal osmotic fragility of erythrocytes in domestic poultry such as chicken, quail and duck making a comparison with that in domestic mammalia such as dog and pig. Osmotic fragility of erythrocytes was determined on blood samples from 10 healthy adult animal in each species. Optical initial hemolysis of erytyrocytes occurred at $0.395{\pm}0.03%$ Nacl for chicken, $0.410{\pm}0.03%$ for duck, $0.440{\pm}0.02%$ for quail, $0.470{\pm}0.05%$ for dog and $0.560{\pm}0.03%$ for pig. Optical complete hemolysis of erytyrocytes occurred at $0.270{\pm}0.02%$ Nacl for chicken, $305{\pm0}.03%$ for duck, $0.360{\pm}0.02%$ for quail, $0.370{\pm}0.03%$ for dog and $0.455{\pm}0.03%$ for p. In other words, erythrocytes of poultry have stronger resistance to osmotic Iysis than that of mammalia, showing the strongest resistance In chicken among the tested poultry.
