Final answer:

The major steps of scientific survey, differences between research and survey, experimental research with an example, importance of observation in scientific learning, and the necessity of safety gear in a science lab.


Explanation:

Major Steps of Scientific Survey:

  1. Define the problem: Clearly identify what you want to learn.
  2. Collect information: Gather relevant data through research.
  3. Formulate a hypothesis: Make an educated guess to answer the problem.
  4. Test the hypothesis: Conduct experiments or surveys.
  5. Analyze data: Interpret results objectively.
  6. Draw conclusions: Summarize findings and implications.

Differences Between Research and Survey:

1. Nature: Research involves systematic investigation while surveys focus on gathering data from a specific group.
2. Scope: Research is broader in scope and may involve various methodologies, whereas surveys are more specific and structured.

Experimental Research:

Experimental research involves manipulating variables to observe their effects. For example, testing a new drug on patients to measure its efficacy is experimental research.

Importance of Observation in Scientific Learning:

Observation is crucial in scientific learning as it helps in gathering data, identifying patterns, and formulating hypotheses. Through observation, scientists can make accurate predictions and draw meaningful conclusions.

Wearing Safety Gear in Science Lab:

Aprons, glasses, and gloves are necessary in the science lab to protect against chemical spills, eye injuries, and skin contamination. Safety gear ensures personal safety and minimizes risks during experiments.
