A student hypothesizes that plants grow taller when given more sunlight. After the experiment, the data shows no significant difference in height. What conclusion is most appropriate?
Answer: The hypothesis is not supported by the data and should be revised
When data does not support a hypothesis, the correct scientific response is to revise or reject the hypothesis based on the evidence.
Which of the following scenarios demonstrates the use of a model in science?
Answer: A student builds a 3D representation of the solar system to understand planet distances
Scientific models are physical or conceptual representations used to understand systems or phenomena that are difficult to observe directly.
Which safety rule is most important when students are using a heat source during a science experiment?
Answer: Wear safety goggles and keep hair and loose clothing tied back
Wearing goggles and securing hair and clothing are essential safety measures when working near heat sources to prevent burns and accidents.
A class conducts an experiment to see if salt affects the boiling point of water. Which of the following would be the independent variable?
Answer: The amount of salt added to the water
The independent variable is the one the experimenter deliberately changes — in this case, the amount of salt added.
Which of the following best describes scientific inquiry?
Answer: A structured process of asking questions, investigating, and drawing evidence-based conclusions
Scientific inquiry is a flexible, evidence-based process of questioning, investigating, and developing conclusions from data.
A student measures a pencil as 14.5 cm using a ruler. The measurement 14.5 cm is best described as:
Answer: A quantitative observation
A measurement with a numerical value and unit is a quantitative observation, distinguishing it from descriptive qualitative data.
Why do scientists use the International System of Units (SI) when recording data?
Answer: To ensure consistency and allow scientists worldwide to understand and compare results
SI units provide a universal standard that allows scientists from different countries to accurately share and compare data.
