Model for a scientific argument
A conjecture, conclusion, explanation, descriptive statement, or an answer to a research question
Measurements of observations that show trends over time, differences between groups, or relationships between variables (and other reasons, such as conclusions of findings from other studies and accepted theories, models, laws, or unifying concepts)
The evidence and claim are explained by a rational
A statement that explains why the evidence and other reasons support the claim, and why the evidence and others reasons should count as support
