Competency Goals:: 4: The learner will conduct investigations and utilize technology and information systems to build an understanding of chemistry.
Objectives:
4.01: Understand that both naturally occurring and synthetic substances are chemicals.
4.02: Evaluate evidence that elements combine in a multitude of ways to produce compounds that account for all living and nonliving substances.
4.03: Explain how the periodic table is a model for:
Classifying elements.
Identifying the properties of elements. 4.04: Describe the suitability of materials for use in technological design:
Electrical Conductivity.
Density.
Magnetism.
Solubility.
Malleability. 4.05: Identify substances based on characteristic physical properties:
Density.
Boiling/Melting points.
Solubility.
Chemical reactivity.
Specific heat. 4.06: Describe and measure quantities related to chemical/physical changes within a system:
Temperature.
Volume.
Mass.
Precipitate.
Gas production. 4.07: Identify evidence supporting the law of conservation of matter.
During an ordinary chemical reaction matter cannot be created or destroyed.
In a chemical reaction, the total mass of the reactants equals the total mass of the products. 4.08: Identify evidence that some chemicals may contribute to human health conditions including:
Cancer.
Autoimmune disease.
Birth defects.
Heart disease.
Diabetes.
Learning and behavioral disorders.
Kidney disease.
Asthma. 4.09: Describe factors that determine the effects a chemical has on a living organism including:
Exposure.
Potency.
Dose and the resultant concentration of chemical in the organism.
Individual susceptibility.
Possible means to eliminate or reduce effects. 4.10: Describe risks and benefits of chemicals including:
Medicines.
Food preservatives.
Crop yield.
Sanitation.
