Scientific Method Ecology- 2015-2016

What is the scientific method? Common steps scientists use to gather information and answer questions https://www.youtube.com/watch?v=GKGtkzgKfkc - We are going to watch this video clip, it is 10 minutes long. No notes are necessary, just watch and enjoy!

Observation Seeing or noticing something

Hypothesis An explanation for a question or problem that can be tested

Experiment A procedure that tests a hypothesis

Control and Variable Control: Group in which conditions stay the same Variable: Group in which conditions are changed

Data Information obtained from the experiment

Analysis Review of the results and determining if the hypothesis was answered…

Reporting Results Sharing the results with others so they can try to duplicate your results (Experiments are only valid if they can be repeated by others)

Qualitative Observation An observation using the five senses The car is red The fan is loud The table is smooth

Quantitative Observation Observation using measurement or numbers Length, mass, time, volume, density, counting, area, temperature…

Length The distance between two points Meters (m), cm and mm

Mass The amount of matter in an object Grams (g, mg, kg)

Area The surface of an object Area = length x width (A= L x W) Units: cm2

Volume The amount of space an object takes up Liquid volume is calculated using mL Solid volume is L x W x H Units: cm3

Temperature The amount of heat present in an object Celsius (and in the US Fahrenheit)

Time The indefinite continued progress of existence and events Seconds, minutes, hours, days, weeks…
