Zinser tech unit state standards
- 1. Zinser_ Tech Unit State Standards Students will demonstrate an understanding of the following state standards: Elements and their combinations account for all the varied types of matter in the world. As a basis for understanding this concept: a. Students know that during chemical reactions the atoms in the reactants rearrange to form products with different properties. b. Students know all matter is made of atoms, which may combine to form molecules. c. Students know metals have properties in common, such as high electrical and thermal conductivity. Some metals, such as aluminum (Al), iron (Fe), nickel (Ni), copper (Cu), silver (Ag), and gold (Au), are pure elements; others, such as steel and brass, are composed of a combination of elemental metals. d. Students know that each element is made of one kind of atom and that the elements are organized in the periodic table by their chemical properties. h. Students know living organisms and most materials are composed of just a few elements. i. Students know the common properties of salts, such as sodium chloride (NaCl).
