This study examined how to produce new methods of copper (II) sulfate crystallization by using a small-scale chemistry tool such as small-scale reaction surface and petri dish. The making of copper(II) sulfate is included in the 5th grade elementary science textbooks. Various copper(II) compounds were reacted with a 2 M sulfuric acid solution. The result of this study is as follows: Seven small amounts of copper(II) compounds were reacted with a few drops of 2 M sulfuric acid solution at room temperature to make a copper(II) sulfate crystal of triclinic shape. Using the petri dish method, a copper(II) sulfate crystal could be identified within one hour of reacting copper(II) hydroxide, copper(II) carbonate, copper(II) nitrate, copper(II) perchlorate, cupric(II) formate from a few drops of 2 M sulfuric acid solution at room temperature. When using the lap top method for copper(II) perchlorate, cupric formate, a proper crystal could be identified within one hour as well. SSC methods were used for the first time to make a copper sulfate crystal via chemical reaction. We can make a copper(II) sulfate crystal using a simple method which is easier, safer and saves time in class. And since a small quantity of chemicals are being used in SSC chemical methods, waste is greatly reduced. This lessens the amount of environmental problems caused by the experiment. This can be helpful in preserving nature. In addition the cost of chemical and laboratory equipment is greatly reduced because it uses material that we find in our daily lives. There will be continued study of small-scale methods such as improvement of new programs, study and training of teachers, and securing SSC tools. I would like to suggest such as SSC methods are applicable in elementary School Science. I would like it to become a wide spread program.

Substance abuse among teenagers has been spreading widely and become a serious social problem. However, teachers hardly realize its importance. Recently, substance abuse prevention programs show a tendency towards one time education. This study aims to research the effect of substance abuse prevention on high school students using the Life Skills Training Program. Two classes(36 students in the experimental group, 35 in the control group) at W High School in Daejeon were randomly sampled for this study from May to June 2002. Substance knowledge and attitude, problem solving, and assertiveness were examined as Pre and Post-Tests. The data was analyzed using frequencies, t-test, means, and covariance(ANCOVA). The results of this study were as follows； 1. Compared with the control group, substance knowledge in the experimental group was significantly improved(F＝176.317, P＝.000). And compared with the control group, substance attitudes in the experimental group were improved significantly.(F＝207.682, P＝.000). 2. Compared with the control group, cognitions to problem solving in the experimental group was significantly improved(F＝100.937, P＝.000). 3. Compared with the control group, assertiveness behaviors in the experimental group were increased significantly(F＝207.255, P＝.000). The study showed that Substance Abuse Prevention of High School Students was effective in improving substance knowledge and attitude, cognition to problem solving, and assertiveness behavior. Some suggestions based on the result are as follows； 1. Substance abuse preventive programs must be practiced properly and systematically with high school students in their regular classes. 2. Various preventive education programs must be developed for substance abuse where high school students can join in a community center, such as Community Welfare Center, Alcoholic Counseling Center, and Mental Health Center. 3. For the furthering of substance abuse preventive education, there must be continued research about not only students with problems of substance misuse and abuse, but also students without them. 4. There must be early determination of students with problems of substance misuse to be able provide school social workers with the opportunity for intervention.
