RESEARCH PURPOSES

The Meaning Of RESEARCH PURPOSES

• In the context of a science experiment, this problem can be written.
• In the form of questions or in the form of statements to be tested.
• It can be done, and is not is a personal opinion.

Which One is REASONS RESEARCH?

• red flowers are better in comparison yellow flowers.
• Is it a plant that is exposed to sunlight will directly produce brighter flower colors in comparison which is not exposed to the sun?

A GROUP CAN CHOOSE ONE EXPERIMENT WITH THE LINK IDEA OF RESEARCH ABOVE OR CHOOSE ANOTHER SIMPLE EXPERIMENT RELATED IN YOJUR DAILY LIFE

DISCUSS WITH YOUR GROUP�MAKE A QUESTION AS A RESEASONS PURPOSES FROM OBSERVATION BELOW?

• Mother often watered the plants use rice rinse water.
• Dad drinks coffee from a cup if at home but when he bought from stalls use glass and from the coffee shop using a glass styrofoam.
• There are no plants living in it soil around the washing area clothes. Organic waste at home usually collected in a particular hole to decompose with the soil. This waste consists of leaves dried, pieces of bark or stem vegetables and leftovers.
• To save daily expenses buy vegetables and cooking spices, our family will plant vegetables and kitchen spices often used for cooking.

How To Write RESEARCH PURPOSES

• Can be written in the form of a statement or question, for example:
• "Investigating the influence of (independent variable) on (dependent variable)“ or
• “How does (independent variable) affect (dependent variable)?“
• Example: Investigating the effect of the amount of fertilizer added to the plants to increase the height of the kale plants.
• How does the effect of the amount of fertilizer added to the plants to increase the height of the kale plants.

HYPOTHESIS AND VARIABLES

A DETECTIVE

• when you become a detective surveying the place In the event of a theft case, you find that there are no doors or windows damaged, and no items were dropped, then the suspicion arises that the theft was carried out by someone who already knew the family and know the situation in the house.

It happened somewhere during the day, what did you observe? Did you expect something to happen?

Scientific Reasons

• When it is cloudy, there is a lot of water vapor contained in the cloud.
• The more water vapor the clouds will form the thicker it gets, so the steam will be sent down in the form of rain.

HYPOTHESIS

​

• Estimation temporary or presumptive answers to the aims of the experiment investigated.
• It must be true logical or reasonable.
• It is more complete if it is supported by reasons from a scientific or scientific perspective.

EXAMPLE ILUSTRATION

• Ketut will investigate the path he can take in the shortest time(quickest) to walk from his house to school. For example, there isthree different paths he will try. One day he tried one route. Hemeasure the time taken from home to school on each routethe. Because Ketut just wanted to find out the fastest route, so himself will walk along each of these paths.
• HYPOTHESIS : If Ketut takes a shorter path to school, then it will take him less time to reach school
• INDEPENDENT VARIABLE : The path taken by Ketut.
• DEPENDENT VARIABLE : The time taken to reach school.
• CONTROLLED VARIABLE : Ketut's walking speed, Starting point (Ketut's house), End point (school), Time of day, Weather conditions

ILUSTRATION 1

• Doni have two bean plants, both planted in the same type of soil and given the same amount of water. One plant, Plant A, place in a sunny windowsill. The other plant, Plant B, place in a dark closet. He is curious about how light affects plant growth.
• RESEARCH PURPOSES : Does amount of light affect the growth of plants? OR the investigate the effect of amount of light on growth of plants?
• HYPOTHESIS : if the plants are different places then it affect the growth of plant
• INDEPENDENT VARIABLE : amount of light
• DEPENDENT VARIABLE : the growth of plants
• CONTROLLED VARIABLE : type of soil, amount of water, type of plant, pot size, temperature
