Science Study Skills

Development of good study skills is an essential part of education. Study skills, just like athletic skills have to be developed. Good study skills require practice and patience. 

Please review the following:  


Identify and list skills that could help improve the time you spend in studying.

Please develop and submit a presentation that demonstrates your understanding of how to improving your study skills. Please address the prompts in your presentation.

Laws and Theories

Many time you'll hear "well it's just a theory" or "a law was made to be broken". In science theories and laws have very specific meanings. 

Please review the follow:


Explain the proper use of the word "theory" as related to science

Compare and contrast "theory" and "law"

Please develop and submit a presentation that demonstrates your understanding of theories and laws as they relate to science.

Scientific Method

The bases of scientific method is consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.


Above is the standard flow chart for the scientific method.

Below is a side by side comparison of the scientific method and engineering method. Notice the similarities and differences.

Please review the following:


Explain the scientific method

Explain the development of a hypothesis 

How many variables are tested in a single experiment


Please develop and submit a presentation that demonstrates your understanding of the scientific method.

Accuracy vs. Precision

Accuracy and Precision:

Accuracy refers to the closeness of a measured value to a standard or known value. ... 

Precision refers to the closeness of two or more measurements to each other.


Givenan object with a known mass of 2.2 kilograms

Your procedure requires you mass the known object 5 times. Each time your scale reads 2.18 kg. The precision would be excellent and the accuracy is very good with a .02 kg error. 

However, let's say your scale reads 1.7 kg, 1.9kg, 3.0kg, 2.2kg, and 1.0kg the precision (how close the scale readings are to one another) and accuracy (how close the readings are to the known value) both are unreliable.

One last case, the readings are 1.7kg, 1.65kg, 1.73kg, 1.7kg and 1.75kg the precision is good but, the accuracy is unreliable.

Accuracy and precision become increasingly important as we begin to standardize equipment in the medical field. Daily all medical equipment must be tested and standard deviation established for each piece of equipment (meaning determine the precision and accuracy of the equipment that's being used).

Standard SI Units

Worldwide scientists have agreed to use a single measurement system called Le Systeme International d Unites or SI units.

SI Base System is defined as the modern form of the metric system and is the most widely used system of measurements. The system is built on seven basic units, which are the ampere, Kelvin, second, meter, kilogram, candela, mole, and a set of twenty prefixes to the unit names and unit symbols that may be used when specifying multiples and fractions of the units.

Prefixes added to the SI base units are used to represent quantities that are larger or smaller than the base units.
