Read and answer the following questions in complete sentences.
Science
Science is a systematic knowledge acquirement process about a system of previous knowledge. Instead, knowledge is a set of principles or universal laws that express, and can predict, the behavior of system under given conditions.
Sciences are classified in two main groups:
1. Factual Sciences: are the based on natural observable facts, as Biology, Physics, Chemistry and the disciplines that flow from them. Factual sciences (or factic) use two study methods: the experimental scientific, and the informative scientific. Both use two objective methods: the deductive-hypothetical and the inductive-hypothetical.
2. Formal Sciences: are the established in the logic reasoning and work with human mind-created ideas. Its work method is the inductive-logical. Examples of this sciences are Math, Sociology, Anthropology, Psychology, Economics, Philosophy, and the disciplines that flow from them.
Factual sciences are those which studies start from observation of natural facts to form a set of organized and trusted facts. As mentioned, biology, physics and chemistry are examples of factic sciences.
· Biology is the science that studies living being in structure, origin, development and functions.
· Physics is the science that studies energy transformations and its relationships with matter.
· Chemistry is the science that studies composition, structure, and properties of matter, and its changes.
Biology, Physics, and Chemistry are closely related sciences, because all the biological process involve transfer, storage, and movements of matter and energy. Besides, energy transfer, its storage and manipulation in living being depends on substances and chemical reactions. On the other side, Astronomy, a branch of Physics, has a close relationship with life because its origin was determined by the stellar evolution. That is, every atom that form part of living, was originated in a star. For example, iron contained in hemoglobin of blood was originated at the moment when atomic nucleus of different elements on a star merged to form heavier elements, among themselves iron.
1.- In 5 lines, write only the main ideas and how does the science relates with Chemistry, Physics and Biology.
______
2- From Sampier definition, what is a scientific experiment?
______
3- What is an observation?
______
4- In few words, how do you plan an experiment?

______
8- What is the difference between Random errors and Systematic errors in experimental measurements?
______
9- What is the difference between precision and accuracy?
______
10- List 4 examples showing the difference between precision and accuracy.
______
11- Define independent and dependent variable.
______
12- Why is making a graph useful?
______
13- Choose 5 security laboratory rules from your laboratory book and write why are they important.
______
______
14- If there is a fire in the laboratory what procedure do you follow?
______
15- Which material will you use to measure precise amounts of volume? Explain.
______
16- Which material will you use to grow bacterial cultures?
______
17- If you are asked to prepare 100 ml of any solution, which material will you use to measure the 100 ml?
______
18- Using a flow chart, design an experiment in which you will prepare 100ml. of a 10% NaCl solution (10 g of NaCL in a total volume of 100 ml.) and then you will separate the water from the salt.
Be sure to include:
- Material that you will use (drawings or pictures)
- Explanation of every step.
Hint:
- At least, you will use 5 different materials that we saw in the lab session to make the solution, and 4 to separate the components of the solution (NaCl and Water)
