Investigative World of Science Cheat Sheet

Key Definitions

• Science: Systematic study of the natural world through observation and experimentation. ✅

• Hypothesis: A testable prediction based on observations. ✅

• Experiment: A procedure to test a hypothesis under controlled conditions. ✅

• Variable: Any factor that can change in an experiment. ✅

Important Concepts

Scientific Method

• Steps: Observation → Question → Hypothesis → Experiment → Analysis → Conclusion. ✅

• Control Group: The group that does not receive the experimental treatment. ✅

• Independent Variable: The variable that is changed in an experiment. ✅

• Dependent Variable: The variable that is measured in response to changes. ✅

Types of Science

• Physical Science: Study of matter and energy (Physics & Chemistry). ✅

• Life Science: Study of living organisms (Biology). ✅

• Earth Science: Study of the Earth and its processes (Geology, Meteorology). ✅

Key Formulas

• Density: How much mass is contained in a given volume.

• Mass: The amount of matter in an object.

• Volume: The amount of space an object occupies.

Common Mistakes to Avoid

Common Mistake: Confusing independent variable with dependent variable.

Common Mistake: Not controlling variables leading to unreliable results.

Memory Tricks

Tip: "H.O.P.E." — Hypothesis, Observation, Procedure, Experimentation — remember the steps of scientific inquiry.
