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.
The first step of an experiment is called?
Any experiment should start with a hypothesis.

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 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
When did scientists start to experiment on animals?
Scientists have been experimenting on animals for centuries, with recorded experiments dating back to ancient Greece and Rome. The use of animals in scientific research became more formalized in the 19th and 20th centuries as the field of biology and medicine advanced. Today, animal experimentation is a common practice in various scientific disciplines.

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.
Why is it a good idea to put your research question into context before you start researching?
I, II, and IV only
