Physical Science- Beginning of year review.
This is a draft cheat sheet. It is a work in progress and is not finished yet.
Science SkillsObserving | Measuring | Organizing | Classifying | Hypothesizing | Predicting | Analyzing | Inferring | Modeling |
Specialized Fields in ScienceBiochemistry Biology+chemistry | Organic Chemistry Most substances that contain carbon | Inorganic Chemistry Most substances that don't contain carbon | Mechanics Study of Motion of Objects | Thermodynamics Heat + its properties | Nuclear Physics Processes in the nucleus of an atom | Astrophysics Celestial bodies | Acoustics Sound + its properties | Optics Light + its properties |
Physical SciencePhysical Science Study of non-living things. Matter+Energy | Chemistry Matter + its changes | Physics Study of all forms of energy, changes among forms | Specialist Person studying a specific field of a subject | Specialization Work in one part of a subject |
| | FormulasArea (cm2) L x W | Volume (cm3) L x W x H or B x H | Volume(Irregular shape) (cm3) V(displaced liquid, mL)= V(object, cm3) | Density g / cm3 |
MeasurementsVolume Amount of space in an object | Density Arrangement of particles in a substance, how closely packed they are in a specific amount of space. Heavy/Light have to do with density | Mass Amount of matter in an object | Temperature Average amount of kinetic energy of the particles in a substance, Hot/Cold |
| | Metric / SIEnglish system Used in USA | S.I - International System of Units Standard used worldwide | Metric Staircase K-h-da-UNIT-d-c-m |
Scientific ExperimentsConstant Factor that remains unchanged | Independent Variable You control; adjustable | Dependent Variable Stimulus that we don't change but is changed by other variables | Control Part of experiment that remains unchanged to compare the results | Scientific Method Series of steps used to investigate a scientific question; steps can be skipped or repeated |
Scientific MethodState the Problem Ask a question about the problem to learn about/solve | Background Research Textbooks, internet, scientific journals, encyclopedias, newspapers | Formulate a Hypothesis Suggest a solution to the problem | Design an experiment Organized process designed to test hypothesis. List all materials and procedure in correct step-by-step order | Collect + Organize Data Detailed charts, graphs, models, drawings | Analyze Data Study data carefully | Draw a Conclusion Is the hypothesis right or wrong? Restate it. Based on analysis of data. |
