d. the amount of cereal 2. Sarah wants to know if mice prefer peanut butter over cheese. In what order should she do the following steps? W Write a report about her findings. X Place a bowl of peanut butter and a block of cheese next to each other in a mouse cage. Y One at a time, place ten mice in the cage and observe which food they prefer. Z Predict which food the mice will prefer. a. Y then X then W then Z b. Z then X then Y then W c. Y then Z then X then W

d. Z then Y then X then W 3. According to the chart provided, how much precipitation is produced in a considerable tornado such as a scale 4 or 5 tornado? a. 12-plus centimeters of rain b. 1 to 5 plus centimeters of rain c. 10-plus centimeters of rain d. can not be determined from this data 4. Medical researchers are designing a new medicine prototype to help relieve symptoms of the common cold. In order to get the best results it is very important to take the correct amount. The correct dosage is exactly 0.5 grams.

Which tool would best help people measure out the correct amount to use? a. Microscope b. graduated cylinder c. A balance d. thermometer 5. Two American car manufacturing companies, Ford and Chevy, have realized that people are willing to pay relatively larges amounts of money for transportation. Select the step from the engineer design process that best represents the actions of Ford and Chevy in this scenario. a. EDP Step-Develop possible solutions

b. EDP Step-Modify and re-rest the prototype c. EDP Step-Test the prototype d. EDP Step-Identify a need 6. Modern technology items are often very useful, but they can also have drawbacks Which use of recent technology has resulted in harm to the environment? a. identifying areas of Earth using global positioning system (GPS) b. disposing of unwanted cell phone batteries in landfills c. searching online information using a personal digital device d. building outdoor furniture using recycled plastics

7. Batman does not have any kind of superpower. Instead he wears a lightly armored suit which protects him from bullets, and he uses infrared devices to allow him to see in the dark. Although Batman is a fictional character, in reality we actually have bullet-proof vests and night vision devices like this. Are these kind of technology items assistive or adaptive? a. The Batman suit permanently gives him super-strength. So it is assistive. b. They are temporary aids, but they do not change the body. So they are assistive. c. By day he is Bruce Wayne, but at night he is Batman. This change is adaptive. d. Batmans armored suit is assistive, but the infrared devices are adaptive. Pencils down, get out a pen to grade your paper.

Use a Dichotomous Key? TOC # 19 Shape Island SPI 0807.5.1 Can I use a simple

classification key to identify an unknown organism Shape Island You are a biologist who has lived for more than a year on Shape Island. There are unique organisms on this island that need to be classified. During your year on the island, you have identified several new organisms and assigned a two part scientific name to each of them. There are 12 creatures left to be named! Being the thorough scientist that you are, you have pledged to finish this job before you sail home. You will use your classification key which contains prefixes,

suffixes, and root words to guide you. SPI 0807.5.1 Can I use a simple classification key to identify an unknown organism Greek & Meaning Latin roots, prefixes, And

Partners! #1 Analyzing Results If you gave species 1 a common name, such as round-face-nonose, would any other scientist know which of the newly discovered organisms you were referring to? Explain. How many SPI 0807.5.1 Can I use a simple classification key to identify an unknown

organism Elbow Partners! #2 Organizing Data Describe two characteristics that are shared by all of your newly discovered specimens. SPI 0807.5.1 Can I use a simple classification key to identify an unknown

organism Whole Group! #3 Making Inferences Choose four specimens. Make a branching diagrams that classifies the specimens. SPI 0807.5.1 Can I use a simple classification key to identify an unknown

organism #4 Applying Conclusions Individual work! One more organism exists on Shape Island, but you have not been able to capture it. However, your supplies are running out, and you must start sailing for home. You have had a good look at the unusual animal and can draw it in detail. Draw an animal that is different from all of the others, and give it a

two-part scientific name.
