Chapter1 Science Form 1=What is SCIENCE part 1

Hmmm,What is Science???Science is a systematic study of natural phenomena and how they affect our lives .This is divided into two which is scientific knowledge and technology .Scientific knowledge is the information obtained from the study of natural phenomena and technology means the application of scientific knowledge for the use of mankind.Snow, tsunami, earthquake, volkanism, global warming are the examples of natural phenomena. Communication such as TV satellites, telephone and laptop.Transportation such as Cars, aeroplane, bus. Agriculture such as Hydroponic method, tractor,and fertilizer. Medical such as Vaccines, antibiotic, X-ray are the examples of technology.
There is a lot of career in science ,I listed 15 career that i know
They are 1)Geologist
               2)Botanist
               3)Pharmacist
               4)Doctor
               5)Teacher
               6)Astronaut
               7)Oceanographer
               8)Physicist
               9)Microbiologist
             10)Chemist
             11)Dentist
             12)Zoologist
             13)Biologist
             14)Engineer
             15)Forensic scientist



In science we also learn what these careers learn such as Biology .They study about  living things such as plants, animals,and humans.Geologist study about rocks, soil, minerals, charcoal, and natural gas. Meteorology study about weather and climate change such as rain and storm.

In this chapter we will also learn about  science laboratory it is about the apparatus and the use of it.

To heat small amount of chemical

• Boiling Tube

To hold small amounts of chemical

• Test Tube

To hold larger amount of chemical

• Beaker
• Conical Flask
• Flat Bottom Flask

To measure volume of liquid

• Measuring cylinder

To measure volume of liquid accurately

• Burette

To measure a fixed volume of liquid

• Pipette 

To support apparatus during heating

• Tripod Stand 

To spread heat evenly during heating

• Wire Gauze

To filter or separate insoluble from mixtures

• Filter Funnel

To contain gas

• Gas Jar

To hold or support apparatus

• Retort Stand With Clamp 

To evaporate excess soluent

• Evaporating Dish

Next, we also learn about physical quantities and their units.What are physical quantities??Physical quantities are a physical characteristic that can be measured. The base quantities are length, mass, time, temperature and electric current .

Length
Length is the distance between two points.The S.I. unit for length is meter ,millimeter,
kilometer , centimeter .The symbol of the S.I. unit is m,cm,km,mm.We use measuring tape and ruler to measure length.

Mass
Mass of an object is the quantity of matter. The S.I. unit for mass is kilogram, milligram, gram. The symbol of the S.I. unit is kg,mg,g.We use lever balance and triple beam balance for mass

Time
The S.I. unit for time is second,minute,hour,day,month,year,and decade.The symbol of S.I. unit for time is s,min,hr.We use stopwatch for time.

Temperature
The temperature is the degree of heat of an object.The S.I. unit for temperature is kelvin and celcius .The symbol of the S.I. unit is K and `C .We use clinical thermometer and laboratory thermometer for temperature.

Electric Current    
The S.I. unit for electric current is ampere. The symbol of S.I. unit for electric current is A.An ammeter is used to measure electric current in a circuit .
