Study Notes

Traits for Generating New Ideas

  • Curiosity, skepticism, creativity, and open-mindedness are essential traits that help scientists generate new ideas.

Publishing Research

  • Publishing peer-reviewed articles in scientific journals allows researchers to share ideas and test/evaluate each other's work.

Scientific Methodology

  • Scientific methodology involves observing and asking questions, making inferences and forming hypotheses, conducting controlled experiments, collecting and analyzing data, and drawing conclusions.

Characteristics of Living Things

  • Living things are made up of units called cells that are based on a universal genetic code, obtain and use materials and energy, respond to their environment, maintain a stable internal environment, grow and develop, reproduce, and change over time.

Biology and Overlapping Fields

  • Biology includes many overlapping fields.

Types of Scientific Statements

  • "The worm is 2 centimeters long" is an observation.

Hypothesis Requirements

  • A hypothesis must be measurable, testable, and observable to be useful in science.

Observations vs. Inferences

  • An observation is a statement about an object based on senses, whereas an inference is a conclusion drawn from an observation.

Skeptical Attitude in Science

  • A skeptical attitude in science means that a new idea will only be accepted if it is backed by evidence.

Unicellular and Multicellular Organisms

  • Unicellular and multicellular organisms are alike in that they are made up of cells, but differ in that unicellular organisms consist of a single cell, whereas multicellular organisms are composed of multiple cells.

Stimuli Examples

  • Examples of stimuli that a bird responds to include light, sound, and touch.

Peer Review

  • To ensure that a scientific work is free of bias and meets standards set by the scientific community, a research group's work is peer-reviewed by anonymous scientific experts.

Characteristics of Organisms

  • A horse and the grass it eats share characteristics such as using energy, responding to stimulus, and maintaining a stable internal environment, but differ in that horses can move from place to place.

Scientific Thinking

  • A bird-watcher's actions, such as observing and taking notes, demonstrate the aspect of scientific thinking known as observation.

Asexual Reproduction

  • Asexual reproduction involves one parent, whereas sexual reproduction involves two parents.
