Teaching the concept and status of bioenergy to learners based on easy and effective test design (Case Study of New Energy - Sustainable)

The aim of this study is to teach the benefits of using new and renewable energies and familiarize students with how to produce biodiesel through easy and effective experimental design. Biodiesel is one of the types of biofuels, new and clean energy from biomass resources, which can be easily provided in order to compensate for the reduction of fossil energy resources and sustainable development and help the environmental pollution crisis, and can be used without changing diesel engines. This fuel is renewable and biodegradable, with less emissions and greenhouse gases, because of these benefits students should be familiar with this new fuel and how it is made. Considering that the document of fundamental evolution in education has paid special attention to the issue of natural resources and familiarizing students with environmental teaching and environmental education, for this purpose, in this article, while introducing biodiesel, an experiment with simple and available materials to prepare biodiesel design. It is easily implemented by students. The ingredients used are vegetable oil purchased from the store, alcohol and a strong base such as sodium hydroxide. In this experiment, the reaction in different conditions in terms of temperature, process time and the ratio of alcohol to oil was examined in the laboratory to obtain the highest efficiency. In this experiment, biodiesel was obtained in optimal conditions with a yield of 96%.
