Socio-scientific issues-based science instruction addresses societal-related issues to promote contemporary science education. Societal-related issues almost always have to be considered in the cultural environment to which they are relevant. This means that the cultural aspects of socio-scientific issues need to be taken into account to develop…

There is a growing reliance on plastic, even though it is a synthetic material that does not decompose. This article presents a series of six mathematics activities that use plastics as the context to teach environmental education to seventh-grade students. The activities can increase students' awareness of the plastic problem while also serving…

This article reports about a lesson series that focuses on engaging students in sustainability, plastics, and life cycle assessment (LCA). The purpose of the lesson series is to give students insights into sustainability in the context of plastics and to foster awareness of and insights into the benefits of the LCA method. The lesson series…

Designing effective educational measures constitutes a key area of action for achieving global sustainability goals. Therefore, the present study examined a training addressing sustainable consumption practices in plastic reduction, fashion and food. An interactive training was held in a German comprehensive high school with grade 11 students,…

This work analyzes the educational proposals designed by 130 future secondary school teachers (FTs) to address socioecological problems--in this case, the presence of microplastics in the environment--, and the relationship with their own perceptions and commitments regarding these problems. The research design was mixed, with both qualitative and…

The goal of this research was to test the effectiveness of a new science curriculum focused on increasing awareness and knowledge of microplastic pollution in middle school students. The curriculum utilized three teaching methods including lectures, object-mediated learning, and peer collaboration to enhance student engagement and learning. The 84…

This study presents the design and application of a didactic sequence aimed at enhancing high school students understanding of recyclable plastic polymers. The proposed teaching strategy incorporates cooperative learning activities to identify different types of plastics, particularly recyclable ones. The goal is to increase student's scientific…

The concept of relative density is introduced in the middle school and high school curricula by an intuitive approach based on the phenomena of immersion and flotation. In high school, the same concept is taught as the ratio between the masses of two bodies of the same volume. This dichotomy of the concept of relative density between the two…

Within the scope of the current study, the researchers developed activities for middle school students to raise their awareness on the harm of plastics and microplastics, which are detrimental to nature and living things. In addition, through the activities developed, the study aimed to provide students with knowledge of and experience with…

Microplastics have been detected in most ecosystems around the world. They affect the environment and organisms in it, including humans and possibly their health. Hence, the analysis of microplastic occurrence in the environment is highly relevant. However, there are only a few practical and easy-to-implement methods published for school use, and…

This STEM research project asks middle school or high school students to work towards creating ecologically friendly packaging. Packaging that can be composted instead of thrown away and collected in landfills and oceans like plastics. This inquiry uses nanocellulose and focuses on water permeability. The fibers of nanocellulose can be dried to…

The study aims to present how to apply a STEM activity in which physical computing principles and computational thinking processes are used as a differentiation practice to be used in the education of gifted students. In the activity, the students designed smart packaging that will provide healthy long-term storage of foods to solve the greenhouse…

As e-commerce increases, the demand for packaging materials and the potential for generating waste and negative environmental impacts also rise. Packing peanuts are a type of plastic packaging material that are used to protect goods during the shipping process. Petroleum-based plastics are common packaging materials due to their low cost, light…

Hands-on learning is a staple in high school science education, as it provides students with a fast-learning curve and a great degree of field competency. However, due to the safety risks associated with high school students in university chemistry laboratory settings, high school students rarely engage in authentic hands-on chemical learning. To…

This study investigated students' meaning-making of polymeric concepts during modelling and discuss students' creation of visible representations in chemistry. The analysis combines a phenomenographic and social semiotic approach and leads to the finding and description of 21 different meaning-making processes. We refer to meaning-making as the…
