identified control and appropriate variables.
SPI 0707.Inq.2 Select tools and procedures needed to conduct a
moderately complex experiment.
SPI 0707.Inq.3 Interpret and translate data into a table, graph, or
diagram.
SPI 0707.Inq.4 Draw a conclusion that establishes a cause and effect
relationship supported by evidence.
SPI 0707.Inq.5 Identify a faulty interpretation of data that is due to
bias or experimental error.
SPI 0707.T/E.1 Identify the tools and procedures needed to test the
design features of a prototype.
SPI 0707.T/E.2 Evaluate a protocol to determine if the engineering
design process was successfully applied.
SPI 0707.T/E.3 Distinguish between the intended benefits and the
unintended consequences of a new technology.
SPI 0707.T/E.4 Differentiate between adaptive and assistive
bioengineered products (e.g., food, biofuels, medicines, integrated
pest management).
Controlled Experiment:
an experiment that tests only one factor at a time and consists
of a control group and one or more experimental groups.
O Control Factor:
a factor in the
experiment that does
not change; it stays the
same throughout the
entire experiment.
O Variable:
a factor that changes in
an experiment in order
to test a hypothesis.
O Control Group:
the group in the experiment
that does not change;
"norm" group; constant; a
variable is not applied to this
group; standard of
comparison (you compare all
other groups to the control
group)
O Experimental Group:
a group whose conditions
are changed or manipulated;
the variable is applied to this
group.
A school had a garden with four sections, each with the same type
of soil. Students covered each section with a different type of
weed-control cloth. The students planted 10 pepper plants in each
section through holes cut into the weed-control cloth. The students
kept all the growing conditions in each section the same. What is
the independent variable in this investigation?
A the number of weeds in each section at the end of the
investigation
B the health of the pepper plants at the end of the investigation
C the type of soil in the garden sections
D the type of weed-control cloth
Science Tools
Meter stick, microscope,
spring scale, stop watch
Thermometer, graduated
cylinder, triple beam
balance
Types of Graphs
O Line graph:
O Shows change over time
O Bar graph:
O Compares two or more objects/things
O Pie graph:
O Shows parts of a whole (out of 100%...)
O Table/chart:
O Organize data
The table below shows different types of pollination data for
the fruit from one plant species.
Which graph best represents some of the data in the table?
A
B
C
D
Students set up four petri dishes. Each petri dish contained the same amount of
nutrient material and bacteria. The bacteria were grown under different conditions
for ten days. The diameter of the bacteria colonies was measured after ten days.
Which statement best identifies the error in their investigation?
A Two independent variables were being used.
B The difference in temperatures between each trial was too small.
C Ten days was not enough time to gather accurate information.
D The investigation had only one control.

Engineering Design Process
O Ask: what is the purpose of the creating the
product? Also research.
O Imagine: brainstorm ideas
O Plan: materials list; prototype
O Prototype- replica or first model
O Create: make the product & test
O Improve: make product better and retest
New Technology
Intended Benefit
O An outcome that
occurs by a
purposeful action;
usually a positive
result that the
engineer meant to
happen
Unintended Consequence
O An outcome that is
not the one intended
by a purposeful
action; usually a
negative result that
the engineer didn’t
mean to happen.
Bioengineering
Assistive Bioengineering
O engineering that
results in a product
or process that helps
living organisms but
does not change
them permanently
Adaptive Bioengineering
O engineering that
results in a product
or process that
changes living
organisms
