3. Use appropriate equipment and technology accurately to measure (in SI or
appropriate units), process, and analyze data.
4. Use evidence from the scientific investigation to develop descriptions,
explanations, generalizations, predictions, and models.
5. Think critically and logically to develop and communicate the relationship
between the variables of the scientific investigation.
Standard #2:
Students demonstrate knowledge of properties, form, changes and interactions of
physical and chemical systems.
Competencies:
I. Examine, describe, compare, and classify matter based on common chemical and
physical properties in a laboratory setting.
2. Explain that energy (light, heat, magnetic, electric, sound, chemical, nuclear, and
mechanical) is transferred, converted and conserved under nonnal conditions.
3. Examine and describe the relationship of kinetic energy to the physical changes in
state.
4. Classify matter as either elements or compounds (mixtures).
5. Examine, describe, model, and demonstrate that substances react chemically in
characteristic ways with other substances to fonn new substances (compounds)
with different chemical and physical properties, while conserving mass.
6. Analyze the effect of multiple forces on movement, speed and direction of an
object, and measure (in SI or appropriate units) and graph the position, direction,
and speed of an object.
7. Demonstrate safe and proper usage of equipment and chemicals while working
cooperatively in a laboratory setting.
8. Compare and contrast the models of the structure of the atom (early Greek
through electron cloud).
9. Examine and describe properties of acids, bases, and neutral solutions. Classify
common household products based on their pH and with the use of indicators.
Standard #3:
Students demonstrate knowledge of characteristics, structures and function of living
things, the process and diversity of life, and how living organisms interacts with each
other and their environment.
'-
Competencies:
1. Recognize sunlight as the major source of energy in living systems.
2. Trace the flow of energy through living systems and demonstrate the conservation ..
of energy and matter within such systems. ii
