Knowledge and Skills Statement

Science concepts. The student knows that relationships exist between the structure and properties of matter.

Teachers should use examples that their students may be most familiar with in everyday life. If students are familiar with agriculture, teachers may use examples such as the differences between organic and synthetic fertilizers. If they have many students who cook, teachers might talk about the various surfaces used for cookware (copper, cast iron, Teflon) and why they are used. In an area where oil and gas production is common, students may discuss the combustibility and viscosity of types of oils and other petroleum products.

a characteristic of a particular substance that can be observed during or after a chemical reaction; a quality that can be established only by changing a substance's chemical identity

substance that occupies space, has mass, and is composed of microscopic particles

observable characteristic of matter that can be used to identify particular materials

characteristic of matter that can be used to identify particular materials

something arranged in a definite pattern of organization; the arrangement of particles or parts in a substance or body; the aggregate of elements of an entity in their relationships to each other

Research

Kostova, Irena. "The Role of Complexes of Biogenic Metals in Living Organisms." Inorganics 11, no. 2 (2023): 56. https://doi.org/10.3390/inorganics11020056

Summary:  Biogenic metals and their various inorganic, organometallic, and coordination compounds are comprehensively studied and extensively used in medical practice. Since the biogenic metals have various chemical properties corresponding to their position in the periodic table, their biological functions are different. The application of metal-based compounds as medications is connected with the oxy-reduction properties and the capability to form coordination complexes, which are involved in many bioreactions. The usefulness of these metals as therapeutic and diagnostic agents is also pointed out.
