8.1: Chemistry 3 Dimensions & Progressions

Unit 2

● Students will be shown a reaction of the formation of Nylon (either a demo or a video) as an inquiry phenomenon. ● Show students the reactants (1,6 Hexanediamine and Sebacoyl Chloride) and have students observe and write as many physical properties as they can. The two substances superfcially appear the same. observations of the reaction and make inferences as to what is happening. Students should also note the new physical properties of the substance that was made. ● Combine the two substances. ● Students write down ● Students explore the chemical identities of polymeric materials frequently used in their everyday lives. They learn how chemical composition affects the physical properties of the materials that they encounter and use frequently, as well as how cross-linking

● I can make observations about a phenomena and inferences about what I think is happening.
