A. Identify the steps of the scientific method?
DedPeter [7]

Answer:

1. The steps of the scientific method consist of seven things: Ask a question, get the research needed for a experiment, (What are you trying to find out? What materials do I need to complete the experiment? What are the procedures needed to complete the experiment?) create a hypothesis, (your educated guess on what you think the results of the experiment will be) conduct a experiment (complete multiple different trials preferably three) to test your hypothesis, make observations and record data during the experiment, draw a conclusion, (Was your hypothesis correct? Yes or no and explain why it is wrong or right) present your findings.

2. A hypothesis is a educated guess that the scientist believe will be the answer at the end of the experiment which is why they conduct a experiment in the first place to find viable data that will support their hypothesis.

3.  Predictions consist of theories that will test the hypothesis (educated guess) because they're the reasoning to why you believe your guess is correct.

4. A control group consists of variables that do not go through change during a experiment, things that remain the same.

5. Data can be presented in many different ways in the form of graphs, charts, or a research paper. You find the data by completing multiple different trials in a experiment, to make sure you have valid results to write down in your data research.

6. Remember that your hypothesis is your educated guess at the beginning of the experiment, what YOU thought was going to happen during the experiment and if the data you received during the experiment supports your hypothesis.

7. Your procedures, perhaps you measured a variable wrong, perhaps you used to much, or to little of a variable, all depends on your experiment.

8. Having people review and test your data by conducting their own experiments will not only make sure that your data is valid but it insures you even more of your conclusion, making it more accepted by other scientists.

Hope this helps.

I get it! Now I know that atomic theory changed with time because...?
Zinaida [17]

Answer:

okay so i hope this helps

Explanation:

In chemistry and physics, the atomic theory explains how our understanding of the atom has changed over time. Atoms were once thought to be the smallest pieces of matter. However, it is now known that atoms are made up of protons, neutrons, and electrons. These subatomic particles are made up of quarks.
