living things are made of cells
• All living things are organized and made of the
same molecules
• All living things grow, develop, and reproduce
• All living things use raw materials, produce, and use
energy
• All living things respond to the environment
• All living things maintain homeostasis
• Populations of living things evolve
what determines if something is a science? -CORRECT ANSWER • Focuses on the
natural world
• Aims to explain the natural world
• Uses testable ideas
• Relies on evidence
• Usually leads to ongoing research
• Involves the scientific community
What does science do? -CORRECT ANSWER it aims to understand the natural
world through observation and reasoning
What are two major types of reasoning used in science? -CORRECT ANSWER •
deductive reasoning- from general to
specific
• inductive reasoning- from specific to
general
What are the main steps of the scientific method? -CORRECT ANSWER - Observation
- Hypothesis
- Prediction
- Experimentation
- Conclusion
hypothesis -CORRECT ANSWER possible explanation for an
observation
prediction -CORRECT ANSWER what you expect if your hypothesis were true
, peer review -CORRECT ANSWER people who read an article and provide feedback
basic research -CORRECT ANSWER is intended to extend the boundaries of what we
