“…According to Lee (2019), guided-inquiry questions was suitable for an organic chemistry course. Students got an opportunity to develop their higher-order thinking skills and activities to engage in a learning activity (Mistry et al, 2016). Therefore, in this study, several questions were provided as guidelines for students to design green chemistry-based experiment of biodiesel synthesis.…”

The use of non-renewable energy sources such as fossil fuels is very contrary to the concept of sustainable development. The principles of green chemistry can be applied to laboratory work through experiments based on environmental issues such as energy. Biodiesel is an alternative fuel to replace fossil fuels which can be made through the process of transesterification of oils. This research aims to apply the principles of green chemistry in biodiesel synthesis experiments; designing and conducting thoughtful and efficient experiments; characterizing biodiesel products and knowing students' responses to green chemistry-based experiments in biodiesel synthesis. The results showed that the principles of green chemistry were successfully applied in the synthesis of biodiesel. Biodiesel products have a bright yellow colour, pH of 7, and density between 0.866-0.892 g/mL. Water contents range from 1.67-3.3, and acid numbers range from 0.69-4.3. 90/10 tests show the results between range 0.5-3% and kinematic viscosity from 4.195-4.995. Students showed a positive response of 75.36% in designing experimental procedures for green chemistry-based biodiesel synthesis.

“…Other types of experiments at this stage are around developing experimental competencies such as judgement, and examples of this type of activity are those which ask students to make a decision, or to perform some basic level of consideration about experimental procedure. For example, in an entry level inquiry experiment, students are required to design their work‐up procedure in a highly structured activity …”

Designing laboratory activities is a real challenge for those working in higher education. There is often an acknowledged frustration with the status quo, but a lack of clear guidance on what strategies might be useful in considering a redesign. This article aims to address the question: what considerations should be taken into account when designing a laboratory activity? To address it, we first describe an overarching framework for laboratory learning, describing it as a complex learning environment. The reason for this is that two clear overarching guidelines emerge -the first is that the laboratory curriculum should be structured so that each new challenge for student is adequately supported by their prior learning so that they can draw on their knowledge to address the new learning situation, and the second is that guidelines for the kinds of preparation for laboratory learning emerge. Based on this framework, we advocate four core principles for laboratory learning that should be considered when designing a laboratory activity regarding the overall purpose, the role of preparation, the teaching of technique, and the consideration of affective dimensions of learning. We illustrate this framework in practice with examples from our own practice, with suggestions on using the literature on laboratory education as a source for curriculum reform within an institution.

“…Organic inquiry-based laboratories have been published (16)(17)(18)(19)(20) that teach techniques and/or traditional reactions. Mistry et al (17) had students design their own liquid-liquid extraction procedure in a guidedinquiry experiment. Students were given a mixture of three compounds to separate that contained an acid and basic compound with characteristic functional groups.…”

Re-casting traditional organic experiments into green guided-inquiry based experiments: student perceptions

Green Chemistry principles can be used to re-cast traditional Organic chemistry experiments into more guided-inquiry based experiments. Inquiry questions related to green chemistry principles and metrics have been incorporated into our laboratory for the development of more guidedinquiry based experiments. Re-casting traditional experiments provides time for guided-inquiry by allowing students to evaluate reaction conditions and wastefulness of reactions. This includes evaluating solvent choices, heating methods, use of renewal materials, and contemplating reactants and products impacts on human health and environment. Students examine the changes as it pertains to green chemistry, the success of the reaction and the potential impacts on the mechanism. Involving students in these discoveries rooted in a guiding question made the Organic experiments guided-inquiry. Students were surveyed about their exposure to green chemistry and guided-inquiry based labs. Examples of some of the re-casted experiments, excerpts from student reports, and student impressions of the theme are presented.
