You are watching: Observing studying and experimenting to find the nature of things
1 chapter #1 arrival to scientific research
2 note 1.1 What is science? scientific research is observing, studying, and experimenting to find the nature that things. 3 major branches of scientific research 1.Biological (botany, zoology, ecology) 2.Physical (chemistry and physics) 3.Earth science (geology, meteorology)
3 What is technology? the is making use of scientific understanding for practical applications. Makes human life easier…cars, electricity, pencils, computers…
4 Hypothesis- education guess. A scientific theory is one explanation that has actually been experiment by recurring observation. Clinical Theories need to 1.Explain observations just and clearly 2.Experiments must be repeatable 3.You must be able to predict native the concept Theories can readjust
5 Scientific legislation states a recurring observation around nature. Describe by indigenous or numbers. 1.Qualitative- describes in native 2.Quantitative- defines uses number or equations.
6 Equations Rectangle Area equation A=L x W universal Gravitational Equation F=Gm 1 m 2 d 2 perform NOT need in note
7 version is a representation of things or event that deserve to be studied to understand the genuine object or event. Greek theory ModelModern Theory model
8 notes 1.2 The scientific method is a way to organize her thinking about everyday questions also as about questions the you can think of together scientific. Scientific technique Question collect Data type a theory Test the hypothesis Observations draw a Conclusion
9 Hypothesis- a possible answer that can be tested. An education guess. Variable: A change is the aspect that is gift tested in an experiment. You must only have ONE variable.
10 issue is noþeles that has mass and volume (occupies) space. Instances air, smoke, water vapor. Volume: is a measure up of space, such as the capacity of a container.
11 load vs. Mass weight is the traction of heaviness on one object. Weight transforms from location to place. Mass is the quantity of matter. Mass never ever changes. Astronauts in space. Is a great example to aid you mental the difference….
12 Metric conversions RULES: 1.Make the chart (Kind Hector Does better During classical Music) 2.Place # into the chart, placed the DECIMAL allude in the row with the starting UNITS. 3.Only 1 # per row 4.Decimal point out are always on the ideal SIDE that row and a # is top top the left of that heat 5.Move decimal suggest to the best SIDE that the row through the ending UNITS. Kilo Hecto Deca basic deci centi milli Meter Liter Grams
13 notes 1.3 Accuracy describes the commitment of a certain value through the true value.Accuracy describes the covenant of a particular value through the true value. Precision refers to the level of agreement among several dimensions made in the very same manner.Precision describes the degree of agreement among several measurements made in the exact same manner. Neither exact nor preciseNeither exact nor precise Precise but not accuratePrecise however not accurate specific AND accuratePrecise and also accurate
14 heat graph is best for displaying data that change. Independent variable is the one you determined the intervals because that (x-axis) Bottom. Dependent variable is the one that depends what happens in the experiment (y-axis) Side.
15 Bar graph is helpful when you desire to compare data for numerous individual item or events.
16 Pie Charts is best for displaying data that are parts of a whole.

17 clinical notation: is a worth written as a basic number in between 1 & 9.999 multiply by a strength of 10. Examples 65 000 = 6.5 x 10 4 0.00012 = 1.2 x 10 -4 8923100000= 8.9231 x 10 9
