In this experiment, two chemicals that can be found around the house will be mixed within a plastic baggie, and several chemical changes will be observed.
Engineers create and use new materials, as well as new combinations of existing materials to design innovative new products and technologies—all based upon the chemical and physical properties of given substances. In this activity, students act as materials engineers as they learn about and use chemical and physical properties including tessellated geometric designs and shape to build better smartphone cases. Guided by the steps of the engineering design process, they analyze various materials and substances for their properties, design/test/improve a prototype model, and create a dot plot of their prototype testing results.
Students will complete a laboratory experiment, followed by answering questions as to whether the changes were physical or chemical in nature.
