- measuring
-
process skill
obtaining exact information
about a quantitative characteristic (measurable feature)
- astronomy
-
branch of science
study of matter in outer space - stating a hypothesis
-
process skill
an explanation
of why something happens
that can be tested/proved by an experiment
- science
-
knowledge
and process for gaining more knowledge
about our world
various branches (examples) - qualitative property
-
describes an object in measurable terms
information about exact measurement
- chemistry
-
branch of science
study of the make-up of matter - issue
- topic about which people have different points of view
- biology
-
branch of science
study of life - observing
-
process skill
watching/examining carefully
with senses of sight, hearing, touching, tasting, smelling
qualitative observations describe (without using numbers)
quantitative observations measure (numbers & units)
- society
-
many individuals
who must work together
responsibly
in the application of scientific knowledge
- physical property
-
characteristic trait/feature/peculiarity
that defines/describes something
e.g. its colour, physical state, texture, hardness
- ecology
-
branch of science
study of organisms in environments - conclusion
-
result/outcome of an experiment
validation/rejection of hypothesis
- physics
-
branch of science
study of matter & energy - characteristic
-
feature/distinguishing mark/trait/property
that helps to identify (distinguish/tell apart)
or describe recognizably
- technology
-
use
of scientific knowledge
to solve a problem
advantages & disadvantages (examples)
- inferring
-
process skill
giving possible explanation(s)
for an observation
(without proof)
- dependent variable
-
value depends on value of the independent variable (effect)
observed and/or measured by the experimenter
- process skills
-
thinking skills
used in a specific order
by all kinds of people
to find answers to questions
- theory
- a well tested hypothesis
- control/control group
-
all variables are kept constant (unchanged)
independent variable is omitted
to make sure that observed changes are caused by the independent variable
gives a basis for comparison
- predicting
-
process skill
describing what might happen in the future
based on previous observations
- doing experiments
-
process skill
planning
and carrying out
a series of activities
to test a hypotheses, find an answer to a question, or a solution to a problem
- chemical property
-
a capability or power to react chemically
e.g. ability to rust, burn, neutralize, etc.
- using models
-
object, design, idea
to help you understand something
you can not observe
e.g. pictures, diagrams, 3-D representations
- controlled experiment
-
fair test (of a hypothesis)
all variables are kept constant
except one (independent variable)
has a control/control group
must be repeatable
- interpreting data
- explaining data or observations
-
recording data (information):
taking notes
making tables
graphing
sketching
reporting experiments
making mind maps
- different ways to preserve data (information) on paper
- quantitative property
-
describes an object in observable terms
information about appearance, taste, smell, feel, sound
- variable
-
factor
likely to change or vary
can affect the results of an experiment
- experimental group
-
test group
affected by independent variable
- controlled variables
- variables that are kept the same (constant)
- estimating
-
process skill
guessing a measurement
- analyzing data
-
carefully looking at experimental data (in tables or graphs)
to find patterns
that will help you understand the results
- classifying
-
process skill
sorting things
that are somehow alike
into groups
- scientific method
- steps followed to solve problems in science
- defining operationally
-
a method of comparison
using observable/measurable characteristics
to describe or define an object/event
- organizing data
-
putting together data or observations
to make discussion with
and understanding by others easier
- independent variable
-
value changed/controlled by the experimenter
influences the value of the dependent variable (cause)
