Question 1: What best describes how scientific theories differ from everyday 'guesses'?
A theory is simply an opinion without supporting evidence
A theory becomes a law if it is proven once
A theory is a well-supported explanation based on evidence and testing
A theory is a step-by-step recipe for experiments
Question 2: Which statement captures the role of controlled experiments in isolating cause?
They ensure every trial uses a different procedure
They change one variable at a time while keeping others constant
They rely on intuition instead of data collection
They avoid using measurements to reduce bias
Question 3: Why is peer review important before publishing scientific results?
It guarantees the research is 100% correct forever
It ensures the study will be widely profitable
It primarily serves to advertise the study
It checks methods and interpretation to catch errors or bias
Question 4: Which scenario shows correct interpretation of correlation versus causation?
If two things vary together, one must cause the other
Two trends coincide, prompting experiments to test for a causal link
Correlation can be used instead of experiments in all fields
Correlation proves causation when samples are large
Question 5: Which principle explains why ecosystems collapse if top predators are removed?
Thermodynamics of closed systems
Genetic drift increasing biodiversity
Homeostasis in individual organisms
Trophic cascades: changes at one level ripple through the food web
Question 6: Which statement best debunks the myth: 'Humans only use 10% of their brains'?
Only neurons, not glia, are used actively
Humans can unlock unused brain areas with willpower
Brains are mostly inactive to save energy
Brain imaging shows widespread activity; most regions have known functions
Question 7: What scientific mindset helps when adapting to surprising data that contradicts expectations?
Always favor complexity over simpler explanations
Ignoring data that contradicts prior work
Doubling down on the original hypothesis without testing
Being willing to revise beliefs based on new evidence
Question 8: Which example shows productive use of models in science?
Using simplified equations to predict trends and then testing those predictions
Rejecting all models because they are simplifications
Assuming a model is the final truth without testing
Using models only for entertainment purposes
