Nature of Science

Slide 2

Science is a subject in school as well as a strategy for examining the normal world . Science is a procedure that utilizations OBSERVATION, INVESTIGATION, MODEL BUILDING and ANALYSIS to pick up learning about the normal world

Slide 3

Scientists need to convey their thoughts Communication is the objective of all experimental or academic research.  It supports rehashed testing and elucidating of thoughts Agreement of mainstream researchers is critical to understanding and sharing of thoughts to people in general Science is total , one revelation is regularly made taking into account the work of others. In the event that you don\'t comprehend what other individuals have done, you need to rehash everything yourself!.

Slide 4

Newton\'s laws of Motion Einstein\'s Theory of relativity Drake Equation Scientific clarifications help us to comprehend the characteristic world. In any case, clarifications can change or be further characterized after some time as more bits of knowledge and data get to be accessible. This photo not just demonstrates the change of vitality to mass, yet affirms Einstein\'s thought that a light-molecule will yield up its quantum of vitality at the same time in a solitary burst.

Scientific Discoveries Abacus-190 AD Use of the math device, with its globules in a rack, was initially reported in China in around 190 AD. The Chinese form was the speediest approach to do aggregates for quite a long time and, in the right hands, can in any case outpace electronic number crunchers. Headache medicine 1899 Little tablets of acetylsalicylic corrosive have most likely cured more minor ills than whatever other prescription. Hippocrates was the first to understand the mending force of the substance. When the new century rolled over, German scientific expert Felix Hoffman culminated the cure. Spiked metal 1873 The world\'s most divisive innovation was imagined not to keep individuals in or out, but rather cows. Scanner tag 1973 Barcodes were considered as a sort of visual Morse code by a Philadelphia understudy in 1952. Presently, dark stripes have showed up on practically all that we purchase. Battery-1800 In 1780s, Italian physicist Luigi Galvani found that a dead frog\'s leg would jerk when he touched it with two bits of metal. His companion, educator Alessandro Volta made the main battery which were voltaic cells stacked in a Voltaic heap.

SCIENTIFIC METHOD FOR PROBLEM SOLVING Organized arrangement of investigative methodology Not generally an unbending arrangement of steps Follows a general example Not all strides are tailed, some are rehashed Objective and tries not to have an inclination in the matter of what the outcomes ought to be Experiments must be repeatable Do numerous trials of the analysis to guarantee Validity Sometimes a Hypothesis should be overhauled after experimentation

Slide 7

State the Problem or ask how or for what valid reason something happens Gather foundation data Form HYPOTHESIS or conceivable clarification for an issue utilizing what you know and what you watch Test the speculation by performing a trial, watching, building models, Or mimicking a circumstance utilizing controlled conditions Analyzing the information, record your perceptions in an information table Draw conclusions and choose if your theory is upheld or not

Slide 8

Visualizing With Models Scientists can not see or work with all that they are researching. A model speaks to a thought, occasion or protest little or too substantial to work with. Models permit individuals to have a superior comprehension of the thought.

Slide 9

Variable: an element that can bring about an adjustment in the aftereffects of an examination Dependent variable : the worth that progressions, what you measure, the information Independent variable : what you change in a test to perceive how it will influence the needy variable Constant : an element that does not change when different variables change Control: the standard you used to think about results

Slide 10

HYPOTHESIS A proposed answer to an inquiry or an issue Usually composed as : If … Then… Because Example: If thicker paper towels splash up more water than slender paper towels, then thicker towels will assimilate more water since they have more material. The more particular the theory the better you will have the capacity to assess the lab If= free Then = Dependent

Slide 11

Technology The utilization of science in our regular lives

Slide 12

Standards of Measurement Precision : How nearly estimations are to each other and how deliberately estimations were made (hit a pinpoint center) Accuracy : looks at an estimation to the genuine or acknowledged worth (around a dead center)

Slide 13

Metric System Called the International System of Units or SI, " Le Systeme Internationale de Unites " utilized all through the world Base Units of Metric Measurement: Meter - length Liter - fluid volume M 3 or cm 3 – strong and gas volume ( l x w x h ) Gram - mass Second - time Celsius- - temperature

Slide 14

1km = 1000m 100cm = 1m 1000mm = 1m 1cm = 10mm 1cm 3 =1ml Metric Prefixes

Slide 15

Practice Problems 1000mm = ______cm = ______m 1liter = ______ml 450m = ______km 77 cm = - _____m 160 cm = _______ mm 14 km = _______ m 109 g = _______ kg 250 m = _______ km
