Project Teaching of “Review of the Theme of Scientific Inquiry” in Junior High School Chemistry: Comparing Vitamin C Content in Different Fruits and Vegetables
Abstract The project is to establish“the comparison of vitamin C content in different fruits and vegetables”by the selection of 4 kinds of fruits and vegetables in common life,such as kiwifruit,pear,purple cabbage and cucumber. It builds roadmap to solve the chemical problem by scientific research through preliminary planning project,planning project comparing the vitamin C content in this four kinds of fruits and vegetables,for the students who can experience a solution with a certain mass fraction of the solute and actual value of quantitative calculation based on the chemical equation to form the scientific concept for material,health and the view that properties determine application. It also cultivates the scientific attitude of strict truth-seeking,questioned critically to develop thought of designing experiment plan by control variables,shaping the key ability to conclusion and reflections on evaluation according to evidence reasoning and experimental results.
