In the present curriculum, it is difficult to understand the early developmental process of the animal by only the photographs in the textbooks, and it is difficult to settle the theory and knowledge that have not been experienced in the cognitive structure. Therefore, this study was conducted as a preliminary biology teacher because it is thought that it should be applied not only to students' living knowledge but also to real life and related to future society. The purpose of this study is to help understand the early development of the animal to observe the development of the sea urchin. This study used Strongylocentrotus purpuratus collected from Sokcho of East coast. Experiments were conducted at a quarry in Baekmigil, Seosin - myeon, Hwaseong, Gyeonggi - do. 2 hours, 4 hours, 8 hours, 16 hours, 32 hours, 64 hours, 128 hours, and lapse of time from the fertilized membrane of Strongylocentrotus purpuratus to the blastocyst And blastocysts were observed. These observations can be used as learning materials, and experiments provide students with the opportunity to experience and establish cognitive structures.

The floristic study for 3 mountains were carried out in August and september in 2016 respectively. The results are followings; the plant taxa of Mt. Bakwolsan areas consist of 62 taxa totally: 31 families 53 genera 47 species 3 varieties, the plant taxa of Mt. Cheongmyeongsan areas consist of 54 taxa totally: 28 families 48 genera 37 species 8 varieties, the plant taxa of Mt. Bonghwangsan areas consist of 49 taxa totally: 29 families 44 genera 38 species 5 varieties 1 formas. Korean endemic plants were founded 1 taxa in Mt. Bonghwangsan. 3 taxa in Mt. Bakwolsan, 2 taxa in Mt. Cheongmyeongsan and 4 taxa in Mt. Bonghwangsan of specially designated plants which were determined by the Ministry of Environment were founded. Rare and endangered species also discovered 1 taxon from Mt. Bakwolsan. The vegetation in the survey area shows general characters of vegetation in the area near the West Sea of Korea, but It is difficult to say that it represents general vegetation of the area because of the lack of specialty or rare plants. The vegetation status of investigated area was comparatively well conserved, but damage was increasing rapidly by development, deforestation, and tramp which inducedby the disturbances of human beings.
