The resources above correspond to the standards listed below:
MD.4.0. Chemistry: Students will use scientific skills and processes to explain the composition, structure, and interactions of matter in order to support the predictability of structure and energy transformations.
4.A.1. Structure of Matter: Cite evidence to support the fact that all matter is made up of atoms, which are far too small to see directly through a microscope.
4.A.1.a. Recognize and describe that the atoms of each element are alike but different from atoms of other elements.
4.A.1.b. Recognize and describe that different arrangements of atoms into groups compose all substances.
4.A.1.d. Provide examples to illustrate that elements are substances that do not breakdown into smaller parts during normal investigations involving heating, exposure to electric current or reactions with acids.
4.A.1.e. Cite evidence to explain that all living and non-living things can be broken down to a set of known elements.
