5. Chp. 1: Objectives Covered
SPI 0707.Inq.1 Design a simple experimental procedure with an 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).

7. Controlled Experiment: an experiment that tests only one factor at a time and consists of a control group and one or more experimental groups.
Control Factor:
a factor in the experiment that does not change; it stays the same throughout the entire experiment.
Variable:
a factor that changes in an experiment in order to test a hypothesis.
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)
Experimental Group:
a group whose conditions are changed or manipulated; the variable is applied to this group.

8. 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

11. Science Tools Meter stick, microscope, spring scale, stop watch
Thermometer, graduated cylinder, triple beam balance

16. Types of Graphs Line graph: Bar graph: Pie graph: Table/chart:
Shows change over time
Bar graph:
Compares two or more objects/things
Pie graph:
Shows parts of a whole (out of 100%...)
Table/chart:
Organize data

17. 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

27. Students set up four petri dishes
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.

30. Engineering Design Process
Ask: what is the purpose of the creating the product? Also research.
Imagine: brainstorm ideas
Plan: materials list; prototype
Prototype- replica or first model
Create: make the product & test
Improve: make product better and retest

36. Unintended Consequence
New Technology
Intended Benefit
Unintended Consequence
An outcome that occurs by a purposeful action; usually a positive result that the engineer meant to happen
An outcome that is not the one intended by a purposeful action; usually a negative result that the engineer didn’t mean to happen.

39. Assistive Bioengineering Adaptive Bioengineering
engineering that results in a product or process that helps living organisms but does not change them permanently
engineering that results in a product or process that changes living organisms
