Answer: The correct order of the scientific method steps is:
- Propose a hypothesis.
- Conduct an experiment.
- Analyze the data.
- Draw conclusions.
Explanation:
The scientific method is an empirical method to get new knowledge, the process initiates with making a question about that what you need to know (0.), that question conducts you to make a hypothesis (1.), which is a conjecture based on the knowledge while the question is formulated. Once you have the hypothesis, you must test it, so you should do an experiment (2.). This experiment will produce data that must be analyzed (3.) to give you arguments to draw conclusions (4.).

Answer:
Flux melting is what melts the material.
Explanation:
When water or carbon dioxide are added to a rock, the rock begins to melt at lower temperatures, creating magma or molten rock.
It is very important to control the conditions of an experiment because FAILURE TO DO THIS WILL MAKE THE RESULTS OF THE EXPERIMENT INVALID.
A controlled experiment refers to an experiment that is conducted under controlled conditions. Conducting experiments under controlled conditions helps scientists to minimize the changes in all other variables with the exception of the ones been tested.
