Look for the green book that has your

GRADE CAM number on it. That is your new

seat!! Get a sheet of

notebook paper and be ready for further

instructions when the bell rings!

Bell Work: 4/8/15

• You will use the same sheet of notebook paper all week! You only have 8 minutes to answer all 7 questions!

• Answer Questions 1-7 from Practice Test A on your notebook paper (You only need to write the letter answer).

• We will review answers with Plickers.

Chp. 1: Objectives CoveredO SPI 0707.Inq.1 Design a simple experimental procedure

with an identified control and appropriate variables.O SPI 0707.Inq.2 Select tools and procedures needed to

conduct a moderately complex experiment.O SPI 0707.Inq.3 Interpret and translate data into a table,

graph, or diagram.O SPI 0707.Inq.4 Draw a conclusion that establishes a cause

and effect relationship supported by evidence.O SPI 0707.Inq.5 Identify a faulty interpretation of data that

is due to bias or experimental error.O SPI 0707.T/E.1 Identify the tools and procedures needed to

test the design features of a prototype.O SPI 0707.T/E.2 Evaluate a protocol to determine if the

engineering design process was successfully applied.O SPI 0707.T/E.3 Distinguish between the intended benefits

and the unintended consequences of a new technology.O 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 investigationB the health of the pepper plants at the end of the investigationC the type of soil in the garden sectionsD the type of weed-control cloth

Science ToolsMeter stick,

microscope, spring scale, stop watch

Thermometer, graduated cylinder, triple beam balance

Types of GraphsO Line graph:

O Shows change over timeO Bar graph:

O Compares two or more objects/thingsO 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.

Bell Work: 4/9/15

• You will use the same sheet of notebook paper all 3 weeks! You only have 8 minutes to answer all 7 questions!

• Answer Questions 8-14 from Practice Test A on your notebook paper (You only need to write the letter answer).

• Work on homework if you finish before the time is up.

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 modelO Create: make the product & testO Improve: make product better and

retest

New Technology

Intended BenefitUnintended

Consequence

O An outcome that occurs by a purposeful action; usually a positive result that the engineer meant to happen

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

Adaptive Bioengineering

O engineering that results in a product or process that helps living organisms but does not change them permanently

O engineering that results in a product or process that changes living organisms
