Grant Joint Union High School District Key Concepts
7. Investigation and Experimentation (throughout the school year)
Note: The abbreviation CCS stands for California Content Standards referenced below.
- Students will use the scientific method to analyze and interpret situations and
solve problems using knowledge developed from more than one area of science.
- Students will use appropriate tools and technology to develop and perform
- Students will recognize the cumulative nature of scientific evidence.
- Students will investigate science-based societal issues.
- Students will formulate explanations using logic and evidence.
Investigation & Experimentation - Grades 9 to 12
Science Content Standards.
1.Scientific progress is made by asking meaningful questions and conducting careful
investigations. As a basis for understanding this concept and addressing the content in
the other four strands, students should develop their own questions and perform
investigations. Students will:
- Select and use appropriate tools and technology (such as computer-linked probes,
spreadsheets, and graphing calculators) to perform tests, collect data, analyze
relationships, and display data.
- Identify and communicate sources of unavoidable experimental error.
- Identify possible reasons for inconsistent results, such as sources of error or
- Formulate explanations by using logic and evidence.
- Solve scientific problems by using quadratic equations and simple trigonometric,
exponential, and logarithmic functions.
- Distinguish between hypothesis and theory as scientific terms.
- Recognize the usefulness and limitations of models and theories as scientific
representations of reality.
- Read and interpret topographic and geologic maps.
- Analyze the locations, sequences, or time intervals that are characteristic of
natural phenomena (e.g., relative ages of rocks, locations of planets over time, and
succession of species in an ecosystem).
- Recognize the issues of statistical variability and the need for controlled tests.
- Recognize the cumulative nature of scientific evidence.
- Analyze situations and solve problems that require combining and applying concepts
from more than one area of science.
- Investigate a science-based societal issue by researching the literature,
analyzing data, and communicating the findings. Examples of issues include
irradiation of food, cloning of animals by somatic cell nuclear transfer, choice of
energy sources, and land and water use decisions in California.
- Know that when an observation does not agree with an accepted scientific theory,
the observation is sometimes mistaken or fraudulent (e.g., the Piltdown Man fossil
or unidentified flying objects) and that the theory is sometimes wrong (e.g., the
Ptolemaic model of the movement of the Sun, Moon, and planets).
