They use library and internet resources to investigate the product to answer the three questions. Students choose or are assigned a synthetic product to research. What are the negative and positive impacts to society of making and using the synthetic product, compared to making and using a more natural product with a similar function?.What chemical processes are used to make the synthetic product?.What natural resources are used to make the synthetic product?.The teacher uses this product to model answers to the three questions students need to answer in their research: This is done by using an example of a synthetic product that students make in the classroom: a gel worm (not for eating.) Students make it by combining a sodium alginate solution with a calcium chloride solution. The teacher models and describes the kinds of information students will be looking for in their research project on a synthetic product. Making and using synthetic materials have both positive and negative impacts on society.A synthetic substance may be chemically identical to a naturally-occurring substance.Some examples of synthetic materials are plastics, medicines, and new fuels.Synthetic materials are made by chemically changing the starting substances to create a material with different characteristics.Synthetic materials are made from natural resources.Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
