The cell is the fundamental structural and functional unit of all known living organisms.

Living systems are organized in a structured way, from simple to complex levels.

Atoms, molecules, organelles and cells are components of the cellular level.

The level above cellular, including tissues, organs, and organ systems.

A biological theory stating that all organisms are made of cells, and that cells are the basic unit of life.

The properties that arise from the interactions of components at a specific level of hierarchical organization, that cannot be predicted by simply looking at the components themselves.

A group of organisms of the same species living in the same area.

A community of organisms and their physical environment.

The highest level of organization; encompasses all Earth's ecosystems.

Understanding the natural world using observation and reasoning.

Using general principles to predict specific outcomes.

Developing general rules from specific observations.

Describing the natural world using the senses or measurement tools.

Different compositional layers inside the earth

A possible explanation for an observation that can be tested to determine its validity.

Hypotheses are not always fixed. When new data is collected, the hypothesis can be changed or refined.

A good hypothesis allows you to make predictions that can be tested with experiments.

An experiment tests the predictions made from a hypothesis. The results either support the hypothesis or lead to its rejection or modification.

The scientific method is an iterative process, meaning that scientists constantly refine their understanding of the natural world through a cycle of observation, hypothesis, prediction, experiment, and analysis.

The starting point of the scientific method, involving noticing something in the world around us.

A hypothesis that can be tested through experiments or observations to prove or disprove it.

One observation can lead to several different possible explanations, requiring further investigation to determine the most likely explanation.

A controlled test designed to investigate a specific hypothesis by manipulating one variable while keeping others constant.

A control group in an experiment is a group that does not receive the treatment or manipulation being tested, serving as a baseline for comparison.

Predictions are specific statements about what will happen in an experiment based on a proposed hypothesis.

A hypothesis is considered more valid when experiments consistently produce results consistent with the predictions made based on that hypothesis.

A hypothesis is rejected when results from experiments contradict the predictions made based on that hypothesis.

A hypothesis gains credibility through repeated testing and surviving multiple attempts to falsify it. This means the hypothesis has been tested against other possible explanations and has emerged as a stronger explanation.

A scientific theory is formed when multiple experiments and observations consistently support a hypothesis. This means the hypothesis has been repeatedly tested and supported through a large body of evidence.

Good experimental design means keeping all conditions constant except for the variable being tested. This ensures any changes observed are due to the manipulated variable and not other factors.

Correlation means two things happen at the same time, but doesn't necessarily mean one caused the other. Causation means one event directly causes another.

Scientific experiments and observations must be repeatable. This ensures that the results are not due to chance or error. If someone else can get the same result, it increases confidence in the findings.

A well-supported explanation of natural phenomena based on a body of evidence from multiple sources.

Evolution is considered a scientific law due to its consistent, extensive support by observations and experiments, making it a fundamental principle.

A casual or tentative guess, often without strong evidence.

Scientific theory is a well-established explanation supported by extensive evidence, while everyday theory is a casual guess.

Atomic theory, gravity, and germ theory are examples of well-established scientific theories.

A research design where neither the participant nor the researcher knows which treatment group the participant is assigned to. This helps minimize bias.

Breaking down complex systems into simpler parts to understand them better.

Studying how the interactions between individual parts create emergent properties in a complex system.

The results of an experiment confirm the proposed explanation, increasing confidence in the hypothesis.

A simplified representation of a complex system, showing how its parts interact. Models help organize thoughts and suggest experiments.

A well-established explanation supported by a large body of evidence and scientific reasoning. It's the highest level of scientific understanding.

In science, a theory is a well-supported explanation, not a guess. In everyday use, "theory" often means a hunch or an idea.

The use of scientific knowledge to solve practical problems and create technologies that benefit humanity.
