Student Experiments on the Topic of Micro-plastics in the Environment for Secondary Education Level II: The Coffee Pad Machine Experiment and Sediment Analysis
AI summary Read the abstract
This paper developed two simple classroom experiments for secondary school students on microplastic topics: extracting microbeads from cosmetic products using a coffee pad machine, and separating microplastics from beach sediment by density — making pollution science accessible to young learners.
Two simple laboratory experiments for addressing the issue of microplastics in the aqueous environment in science teaching are developed. Extraction of microbeads from cosmetic products using a coffee pad machine makes students aware of the potential emission of microplastics into the environment by using these products. Density separation of microplastic particles from beach sediment samples on the other hand demonstrates the difficulty of dealing with the problem once the particles have entered the environment. Using the low-cost experimental set-up facilitates integration of the microplasticsâ topic into laboratory teaching making science lessons vivid and more interesting.
