It is typically specific, measurable, and structured to guide research and experimentation. Such questions often begin with "how" or "why," allowing for systematic investigation and analysis.


What statement best describes a scientific question?

A scientific question is a clear, testable inquiry that seeks to explore relationships between variables or phenomena. It is specific and measurable, allowing for investigation through experimentation or observation. Effective scientific questions typically stem from observations, existing knowledge, or gaps in understanding, guiding research and hypothesis formation.

Which describes the best approach when conducting a scientific experiment?

The best approach when conducting a scientific experiment involves clearly defining a testable hypothesis, designing a controlled experiment to isolate variables, and ensuring reproducibility of results. It’s essential to collect and analyze data systematically, using appropriate statistical methods to validate findings. Finally, documenting the process and results transparently allows for peer review and further investigation by others in the scientific community.


What are the best materials to use for an investigation?

The best materials for an investigation depend on the nature of the inquiry, but generally, high-quality documentation, such as scientific journals, credible websites, and primary sources, are essential. Additionally, tools for data collection, like surveys or instruments for measuring variables, can enhance accuracy. Using reliable software for data analysis also helps in drawing meaningful conclusions. Overall, a mix of qualitative and quantitative materials is often most effective.


What would be the best tool for looking at cells in a scientific investigation?

A microscope would be the best tool for looking at cells in a scientific investigation, as it enables researchers to visualize cells at the microscopic level and study their structures and organelles. Advanced microscopes, such as electron microscopes, offer higher magnification and resolution for detailed cell analysis.


Which of the the following questions is testable in a scientific investigation?

A testable question in a scientific investigation is one that can be answered through observation, experimentation, or measurement. For example, "Does increasing the amount of sunlight a plant receives affect its growth rate?" can be tested by manipulating sunlight exposure and measuring growth. In contrast, questions based on opinion or beliefs, such as "What is the best flavor of ice cream?" are not testable.
