Understanding Scientific Experiments: Key Vocabulary and Concepts

This guide covers essential scientific vocabulary related to experiments and hypotheses. It introduces key terms such as hypothesis, control group, experimental group, and independent and dependent variables. You will also learn about plotting data on graphs, including the x-axis and y-axis, as well as fundamental concepts like inference, volume, mass, weight, temperature, and constants in experiments. This foundational knowledge is crucial for conducting and analyzing scientific research effectively.

  1. Science Fundamentals Unit Vocabulary

  2. Hypothesis An “if…then” statement that is an explanation for a problem that can be tested by making observations or performing experiments.

  3. Control Group • A group that does not receive the independent variable in an experiment.

  4. Experimental Group • The group that is exposed to the independent variable in an experiment

  5. Independent Variable • A factor that is changed or manipulated in an experiment

  6. Dependent Variable • The variable that is measured in an experiment

  7. X - Axis • The line on a graph that runs horizontally (from left to right) through zero

  8. Y - Axis • The line on a graph that runs vertically (up to down) through zero.

  9. Inference • Reaching a conclusion by using logical reasoning

  10. Volume • The amount of space occupied by a solid, liquid, or gas.

  11. Mass • The amount of matter in an object.

  12. Weight • The force exerted on an object due to gravity.

  13. Temperature • A measure of the hotness or coldness contained in matter – also a measure of the kinetic energy of matter.

  14. Meter • The metric base unit of length

  15. Liter • The metric base unit of volume

  16. Gram • The metric base unit for mass

  17. Celsius • Temperature scale in which water freezes at 0 and boils at 100

  18. Constants • Variables in an experiment that are kept the same for all groups and trials

  19. Quantitative • Description of a measurement using numbers

  20. Qualitative • Description using words

  21. Bias • Prejudice in favor of or against one thing, person, or group compared with another, that can alter the results of an experiment
