The Essence of Science Measurement and Scientifiq Method

1. The essence of science, measurement, and scientific method SMP ISLAM AL – AZHAR 10 KEMBANGAN

2. Imtaq “ Sempurnakanlah takaran dan timbangan , dan jangan kamu merugikan orang sedikitpun . Janganlah kamu berbuat kerusakan di bumi setelah ( diciptakan ) dengan baik . Itulah yang lebih baik bagimu jika kamu orang beriman ”. ( QS. Al-A’raf:85 )

3. Science Science is the knowledge obtained from the study and verification. The limits of science are based on the human senses. Science theories are analyzed using scientific method and systematized through observation and research and drawing conclusion

4. Why study science ?

5. The object of science

6. Science Laboratory Tools Image and Tool name Function Bunsen burner Place for burning spirits Tripod For supporting apparatus during heating Erlenmeyer For containing chemicals Test tube For containing small amounts of chemical

7. Image and Tool name Function Beaker glass Liquid storage Measure glass For measuring the volume of liquids Rack To keep test tube Dropping pipette For taking small amounts (drops) of liquid Surgical tools For perform surgeries filtration funnel For filtrating liquids

8. Symbol Type of hazardous substance Proper Handling Examples of chemicals Flammable substance Keep away from fire heat Petrol, kerosene, alcohol Explosive substane Follow correct procedure TNT, Ammonium nitrat Corrosive substance Avoid direct contact Strong acid and alkali Poisonous or toxic substance Don’t drink, eat, taste the substance Mercury, cyanide, chlorine gas Irritating or stimulate substance Avoid inhaling the vapour Alcohol, chloroform Radioactive substance Strictly adhere to all safety preauctions Radioactive carbon, uranium Hazard Symbols

9. Observation of Science Observation using sensory perception, including measurements by using the appropriate gauge, observations were conducted to collect data and information. Make an Inference Formulate an explanation based on observation. This description is used to discover patterns that were observed and make estimates. Communicate communicate the results of an investigation into whether oral or writing. things are communicated including data presented in the form of graphs, tables and pictures.

10. Scientific Method The scientific method is the method or approach used in the research of the science. Indeed, the steps in the scientific method are used in various fields of work. The stages in scientific method are carried out sequentially, which are as follow :

11. Determining experimental goal /formulate a problem ( melalui observasi lingkungan ) Make observation ( Pengumpulan data awal ) Writing hypothesis ( Membuat dugaan sementara ) Experimental procedures ( rancangan untuk menguji hipotesis ) Make a conclusion Make a report ( menuliskan laporan penelitian )

12. Variables in the experiment A variable is a factor, condition, element, which can be either a number or the types that determine in an experiment An experiment has three kinds of variables: Free variables ( variabel bebas ) Bound varibles ( variabel terikat ) Control variables ( variabel control )

13. Measurement The measure is an activity to compare a quantity measured by the magnitude of a kind used as a unit. Try to measure the length of the notebooks, desks and books packages you guys!

14. Tools to Measure

15. The unit prefix in the SI and Multiply

16. Exercise The question of whose unit coversion 1. 0,35 km = .... m 2. 4000 Nf = …. F

17. Magnitudes Of Principal

18. Magnitude Of The Derivative Derived quantities and magnitudes of principal. Example: Area, Volume, force, work, etc

19. POST TEST Write down seven points and its international unit of quantity!
