The Future of Education

Experimental studies encourage students to learn and apply knowledge and skills via experience. The role of the teacher is shifted to the students and students work independently through the learning process. Learning becomes long-lasting, and inspires students a love of science even in tough subjects.
Experiment-based studies create a permanent perception of subjects by incorporating, hands on experience. Students, whom are researches in this case go through several scientific processes. Observation, research, material collection, sample preparation, data collection, results and discussion. In order to come up with an experiment, the individual must be the supervisor of himself. Therefore the observation skills of students are developed through embodying awareness for the environment. Scanning through articles and previous research, investigating in materials hold a longer period in the experiment process. Setting each experimental group in great care so that the dependant, independent and constant variables don’t change, is another function acknowledged through this period. Consequently, evaluating the final results and criticizing the experiment develops a self-sufficient evaluation ability. In the following procedure, students are able to apply to scientific programs for a chance to be recognised by valuable foundations and educational institutions for their projects and findings to be more sustainable and put into action. This experiment based study focuses on the effect of zeolite in heavy metal absorption from soil.
Wastewater generated during the production and use of heavy metals contains a high concentration of toxic heavy metals and pollutants. The leakage of toxic heavy metals into the receiving environment results as a damage to the living things via the food chain and reaches human beings through consumption. The significant source of heavy metals is sewage, wastewater, exhaust gases, and mining. The elimination of heavy metals from soil is highly expensive and challenging. This study involves an economical, sustainable and efficient way to prevent heavy metals to combine with spring waters by adding zeolite into the soil. The most common heavy metals found on land are lead, nickel, and copper. Therefore this study focuses on these three compounds. After testing with various concentrations ranging from %12.5 to %90 for 4 weeks, it has come to the conclusion that a %60 zeolite for copper, %50 for nickel and %25 for lead are optimum for the eradication of heavy metal.
