Scientists conduct research before beginning an experiment to understand existing knowledge and theories related to their topic, which helps them formulate hypotheses and design effective experiments. This background research allows them to identify gaps in current understanding, avoid duplicating previous work, and refine their methodologies. Additionally, reviewing relevant literature enables scientists to anticipate potential challenges and improve the reliability and validity of their findings.
What else can I help you with?
Why should you research a topic before creating an experiment?
so you can know more about the topic before you start
What do scientists need to do if they make a mistake and need to retest the experiment?
They need to keep a record of each step, then start the experiment over and try not to make the mistake again or make changes in what they did to see what outcome they get.
Assume that bacteria appeared on the meat in all three jars How would most scientists today explain this observation?
a.) Bacteria was present on the meat at the start of the experiment.
What do scientists do to test a hypothesis?
This is called scientific method. First; you start off with a question, and then you try to guess an answer to your question with a hypothesis, then you run an experiment and analyze the results and come to a conclusion.
What is the step by step directions for conducting an experiment?
To conduct an experiment, start by clearly defining your research question and hypothesis. Next, design the experiment by selecting variables, creating a procedure, and determining how you will collect data. Conduct the experiment, carefully following your procedure while ensuring to control variables. Finally, analyze the collected data, draw conclusions, and communicate your findings.

What is the difference between experiment and hypothesis?
An experiment is the thing that you perform, and a hypothesis is the guess you make at the start (before the experiment) to determin what's going to happen.
How does a hypothesis start?
A hypothesis typically starts with posing a question or making an educated guess about the relationship between variables. It is a testable statement that predicts the outcome of an experiment or research study.
What do you do to start your experiment?
READ the ENTIRE procedure BEFORE you start, noting safety precautions and materials that you'll need.
What do scientists need to do if they make a mistake and need to retest the experiment?
They need to keep a record of each step, then start the experiment over and try not to make the mistake again or make changes in what they did to see what outcome they get.
What do scientists need to carry out before they start working with a new chemical?
whether they will die or not
What is PHEOC?
THE SCIENTIFIC METHOD: A five-step process that scientists use to solve problemsThe acronym for the steps is PHEOCPHEOC is an acronym forPROBLEM: Scientists start with a problem and form a question from the problemHYPOTHESIS: Scientists then make a scientific prediction about the results of an experimentEXPERIMENT: Scientists make a plan to solve the problem and put it into actionOBSERVATION: As the experiment is taking place, a scientist will watch what happens and take notes on what is happeningCONCLUSION: After the experiment is over, scientists make a final statement about the results, and if their prediction was correct or not
Assume that bacteria appeared on the meat in all three jars How would most scientists today explain this observation?
a.) Bacteria was present on the meat at the start of the experiment.
When did scientists start to experiment on animals?
Because it is not legal or ethical to perform toxicology research on humans, scientists use animals such as fish, mice, and other organisms whose bodies respond similarly to those of humans. These are called animal models.
What do scientists do to test a hypothesis?
This is called scientific method. First; you start off with a question, and then you try to guess an answer to your question with a hypothesis, then you run an experiment and analyze the results and come to a conclusion.
What was the challenging situation when raman started his experiment on light?
The challenging situation at the start of Raman's experiment on light was the lack of advanced equipment and resources in India compared to institutions in Western countries. This made it difficult for Raman to conduct his research and prove his findings.
