Unit Scientific Method
Unit 1 Scientific Method
Using one or more of your 5 senses to gather information about the world
see, hear, taste, smell, feel
Examples of observations
dog bark, smelling smoke, counting 12 green seeds
information collected through observations; evidence
interpret an observation
examples of inferences
dog barks, you infer someone is at the door; baby cries- hungry, wet, hurt
put things together in groups based on characteristic that they share to make it easier to study
how do we classify shapes
size, shape, color, how it's used
smaller version of an object. makes it easier for scientists to study.
examples of models
drawings, physical models
why do scientists communicate with eachother?
what is science inquiry?
it is thinking like a scientist: being inquisitive, asking why, and searching for answers
What is the standard system of measurement used by scientists around the world?
International System of Units or SI
why are si units easy to use
they are based on units of 10
What do scientists use to measure length?
What two instruments are used by scientists to measure length?
metric rulers and meter sticks
What are some common SI prefixes?
What is the volume of a liquid?
the amount fo space the liquid takes up
What is the unit of measure scientists use to measure liquid volume?
What instrument is used to measure liquid volume?

a balance is used to measure mass
unit of measure used to measure mass
Larger masses are measured in. . .
used to measure the temperature of something
water freezes at
water boils at. . .
unit used to measure time. . .
how do scientists share the data they gather?
Steps to a scientific investigation:
1. pose a question
2. create a hypothesis
the factor that you change in an experiment is called...
independent or manipulated variable
the factor that chages the result of the independent variable
responding or dependent variable
an experiment in which all factors except for one are kept constant
a statement that describes how a particular variable is to be measured or how a term is to be defined.
the observations and measurements you make in an experiment
a statement that sums up what you have learned from an experiment.
Where do scientists record their measurements and data
used to display data in a number of separate, or distinct, categories
used to show how one variable (responding variable) changes in response to another variable (control)
a graph or chart that shows a category compared to 100%
A question or purpose to guide your activity
problem, question, or objective
The background information to help answer the problem question
an educated guess written as an if. . . then statement
list of items used ot conduct experiment
sequential list of the steps to complete experiment
details about what is observed during the lab using your five senses. recorded in tables, graphs, diagrams
a summary of data collected based on facts, not opinions. an interpretation of the data
An answer to the problem question based on data collected and applied to real life situations. Flaws in experiment are explained.
