The Nature of Science Chapter 1

 Science is the pursuit of observing facts in order to understand the world we live in

Go Bananas!  Observing facts  Use your senses  Inference  Use what you already know

 Pure Science is the search for scientific knowledge  Technology is the application of that knowledge

 Science is a process not a set of facts.  Information about the world around us is always changing.

 Always starts with a question.  Searching for an answer is doing Science

A problem solving attitude think critically about a question test possible answers collect data unbiased observations

The Scientific Method a systematic approach to problem solving a way of thinking using logic and reason NOT a rigid set of steps

Scientific Theory explanation that has been tested by repeated observations always being questioned and examined a possible explanation

Scientific Law a summary of natural events states a repeated observation about nature quantitative/qualitative

Scientific Model a representation of an object or event can be studied to understand the real object or event

Facts and Fiction Historical Facts a true statement about the existence of something or about a past event

based on physical evidence  fossil, skeleton, ruins based on recorded evidence  writings, drawings

Facts and Fiction Scientific Facts based on observation  using the 5 senses  must be measurable and repeatable

Facts and Fiction Tools scientists use to make observations microscope telescope spectrophotometer

Facts and Fiction Universal Statements either includes everything or excludes everything can’t be proven by observation

Facts and Fiction Value judgments placing value on things observation can not determine value

Facts and Fiction Biblical Truth the Bible claims to be the Word of God (II Tim 3:16) eternal spiritual importance

Evidence  fulfilled prophecy  accurate records of history  accurate descriptions of world  inner testimony of believer

Mathematics Language of Science International System of Units SI Units are used for consistency Table 1-1 page 16

SI Units based on the metric systemmetric system Prefixes for very large or very small measurements Table 1-2 &1-3 page 16

SI Units Practice on page 17 Making Measurements page 18 copy Vocab into Notes

Scientific Notation method for recording very large or very small numbers reduces the number of zeros (powers of 10)

Significant Numbers the digits in a measurement that are known with certainty shows the accuracy of the tool being used

Significant Numbers Accuracy – extent to which the measurement approaches the true value Precision – degree of exactness of a measurement
