They identify an environmentally friendly alternative, support their decision with evidence, and make a presentation to the class. They demonstrate their ability to apply scientific skills and processes when they identify attributes and classify materials, examine consequences of using synthetic and natural materials, develop environmentally friendly options, and conduct surveys. Skills and processes Students work independently or with a partner to examine a collection of natural and synthetic materials that have not previously been discussed in class. Knowledge Students create a Venn diagram to compare and contrast natural and synthetic materials that could be used for the same function. Criteria could include specificity, number of points of comparison, and inclusion of unique properties that make synthetics useful.
Students use the survey results as part of a self-assessment of their presentations.
