Third Quarter topics- Chemistry:
1. Understand both naturally occuring and synthetic substances are chemicals.
2. Evaluate evidence that elements combine in a multitude of ways to produce compounds that account for all living and nonliving substances.
3. Explain how the periodic table is a model for: classifying elements and identifying the properties of elements.
4. Describe the suitability of materials for use in technological design: electrical conductivity, density, magnetism, solubility, malleability.
5. Identify substances based on characteristic physical properties: density, boiling and melting points, solubility, chemical reactivity, and specific heat.
6. Describe and measure quantities related to chemical/physical changes within a system: temperature, volume, mass, precipitate, and gas production.
7. Identify evidence supporting the law of conservation of matter: during and ordinary chemical reaction matter cannot be created nor destroyed and in a chemical reaction, the total mass of the reactants equals the total mass of the products mass.
8. 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, and asthma.
9. Describe the factors that determine the effects a chemical has on a living organism including: exposure, potency, dose and the resultant concentration of chemicals in the organism, individual susceptibility, and possible means of eliminating or reducing effects.
10. Describe risks and benefits of chemicals including: medicines, food preservatives, crop yield, and sanitation.
