What Do We Use To Make
Observations?
2. Instruments: devices used to extend our
senses

Investigations
Field Studies
Experiment
Surveys
Types of Data
Qualitative = Data obtained by using
your senses. Descriptive Ex: the
paper feels rough, the leaves are red.
Quantitative = Data obtained by using
tools to take measurements.
Ex: the paper clip weighs gram,
it is 92° outside.
Data Gives Us Ideas
6. Inferences: a conclusion that logically
follows a set of observations.
Inferences can be right or wrong
• Ex: You observe your neighbor’s garden
plants are tall and green.
• You know the neighbor fertilizes the
garden
• INFERENCE: the fertilizer causes the
plants to grow tall and be green.
