The scientific method is the process created in the seventeenth century through which hypotheses are developed, tested and either proven or disproven. It is the organized process of determining the legitimacy or accuracy of scientific concepts.
A) Define purpose (through observation or asking questions)
I want to know if water freezes faster on its own or with sugar added
Will water freeze faster or slower with the addition of sugar?
Test of the hypothesis and data collection
Place two containers of equal amounts of water, one with sugar added, into the freezer. At intervals of 30 minutes, open the freezer to determine the status of each container. Continue until both have frozen. Write down the times that the containers were checked and when they each reached a fully frozen level.
Review the data.
Decide: Did water freeze faster or slower with the addition of sugar?
Report findings either verbally or in written format.
B) Define purpose (through observation or asking questions)
I want to know if a bean plant will grow more quickly outside or inside.
Which will grow more quickly in the period of 3 weeks - a bean plant placed outside or a bean plant placed inside?
Test the hypothesis and data collection
Plant 4 bean plants in same sized pots with the same type of soil. Place two in an outdoor location and two in an indoor location.
Each day, for 3 weeks, observe and measure plant growth. Ensure that plants receive equal amounts of water.
Review data and determine how plants in both environments progressed in two weeks.
Based on data, determine if there is a conclusive answer to the question of whether a bean plant placed outside or inside will grow more quickly.
Orally or in written form share the results of the experiment.
The scientific method consists of six steps:
The scientific method is employed when creating and executing an experiment. The purpose of the scientific method is to have a systematic way of testing ideas and reporting results in the process of scientific inquiry. A key component of the use of the scientific method is that it ensures that the experiment should be able to be replicated by anyone. If that is not possible, then the results are considered invalid.
The process of executing an experiment using the scientific method also ensures that data is recorded and able to be shared so that any bias on the part of the scientist performing the experiment can be reduced. Furthermore, the communication of the results allows for peers to review the work to ensure that the results are precise and accurate.
