Document Summary

Chapter 1 matter, measurement and problem solving. The properties of matter are determined by properties of atoms (submicroscopic particles that makes fundamental building block for matter) and molecules (2 or more atoms joined in specific geometrical arrangement) Chemistry: science that seeks to understand behavior of matter by studying behavior of atoms and molecules. Scientific knowledge is empirical (based on observation and experiment) leads to hypothesis (tentative explanation of observation) test hypothesis through experiments (highly controlled procedures to generate observations and see if hypothesis is wrong or correct) Series of similar observations can lead to scientific law (brief statement that summarizes past observation and predicts future ones) or a theory (model for the way nature is and t ries to explain what and why) In summary, this is called the scientific method. Example: law of conservation of mass (antoine lavoisier) in a chemical reaction, matter is neither created nor destroyed (a law summarizes a series of related.

Which of the following statements is TRUE?

A hypothesis is speculation that is difficult to test.
	A scientific law is fact.
	An observation explains why nature does something.
	Once a theory is constructed, it is considered fact.
	A scientific law summarizes a series of related observations.

The scientific method is the backbone of every science experiment, but it's not just for scientists. Most people unconsciously use the scientific method on a daily basis, for example, when performing tasks like cooking or budgeting. In order to help you to better understand the scientific method and the process used, I would like you to give an example of something you have done recently in which you used the scientific method.

In your main post, please trace each step (given below), and don't forget to include your hypothesis and whether you accepted/rejected it at the end.

Steps of the Scientific Method:
1) Make an observation
2) Ask a question
3) Do background research
4) Form a hypothesis
5) Conduct an experiment
6) Analyze your data
7) Make a conclusion --> Do you accept or reject your hypothesis?
