In science, we use symbols to represent quantities. We assign these quantities specific measurement units. Copy and complete Table in your notebook.

$$\begin{matrix} \text{Electrical quantity} & \text{Electrical quantity symbol} & \text{Unit of measurement} & \text{Unit of measurement symbol}\\ \text{patential difference} & \text{ } & \text{ } & \text{ }\\ \end{matrix}$$

For each of the following futuristic scenarios, decide whether it is plausible according to our present understanding of science or whether it is unlikely to be possible. Explain clearly.
A single great galactic civilization exists. It originated on a single planet long ago but is now made up of beings from many different planets, all assimilated into the galactic culture.

The Latin root -frict- means "to break." A refractory animal is one that "breaks away." The root -fract-*appears in some scientific and mathematical terms, such as fraction. A fraction is a part "broken away" from a larger whole. Explain how the root -fract- contributes to the meaning of below italicized word.
"The fracto-stnatus clouds were ragged and appeared in long, threadlike layers."

Jude is making a poster for his science project. The poster board is $22$ inches wide by $27$ inches tall. He wants to cover two thirds of the area with text or pictures and leave a top margin $3$ times as wide as the side margins and a bottom margin twice as wide as the side margins.

What should be the widths of the margins?

The following sentence maybe contain an appositive phrase. Draw one line under each appositive phrase and two lines under the word or words to which the phrase refers. If the sentence contains no appositive phrase, write None at the end of the sentence

The Museum of Science and Industry, located in Chicago's Hyde Park neighborhood, is near the University of Chicago.

For each definition below, choose the key term that best matches the definition. a. someone who eats few or no animal foods b. the ABCs of healthful living. carbohydrate, daily value (DV), Dietary Guidelines for, Americans, fat, Food Guide Pyramid, mineral, nutrient, nutrient deficiency, nutrient density, nutrition, protein, Recommended Dietary, Allowances (RDAs), vegetarian, vitamin.

Forensic Science An inequality that is used to calculate the height $h$ of an adult male from the length $r$ of his radius is

$$|h-(3.32 r+85.43)| \leq 4.57$$

where $h$ and $r$ are both in centimeters. Use this inequality to calculate the range of heights that an adult male with a radius of $26.36$ cm might reach, rounded to the nearest tenth of a centimeter.

In science, we measure quantities and use symbols to represent quantities. We also assign measurement units. Copy and complete Table in your notebook. Internal Resistance.

$$\begin{matrix} \text{Electrical} & \text{Electrical} & \text{Unit of} & \text{Unit of}\\ \text{quantity} & \text{quantity symbol} & \text{measurement} & \text{measurement symbol}\\ \text{resistance} & \text{ } & \text{ } & \text{ }\\ \end{matrix}$$

A high school Family and Consumer Science class has $12 \frac{1}{2}$ pounds of flour with which to make soft taco shells. There are $12 \frac{1}{2}$ cups of flour in a pound, and it takes about $\frac{1}{3}$ cup of flour per shell. How many soft taco shells can they make?

The Latin root -frict- means "to break." A refractory animal is one that "breaks away." The root -fract-*appears in some scientific and mathematical terms, such as fraction. A fraction is a part "broken away" from a larger whole. Explain how the root -fract- contributes to the meaning of below italicized word.
"The fractious boys caused a good deal of trouble at school."

Determine whether each statement makes sense or does not make sense, and explain your reasoning.

In a whispering gallery at our science museum, I stood at one focus, my friend stood at the other focus, and we had a clear conversation, very little of which was heard by the $25$ museum visitors standing between us.

Advances in medical science and healthier lifestyles have resulted in longer life expectancies. The life expectancy of a male whose current age is x years old is $f(x)=0.0069502 x^{2}-1.6357 x+93.76 \ (60 \leq x \leq 75)$ years. What is the life expectancy of a male whose current age is 65? A male whose current age is 75?

Study the chart that explains the process archaeologists follow when excavating for evidence of how early hominids lived. Which of the following is the missing step? A Geologists examine seeds and animal bones at the site B Archaeologists record the description and location of each artifact C Botanists analyze blood stains found on artifacts D Zoologists determine the age of the rocks surrounding the dig

Most people think of science as being a specific, exact discipline, with a "correct" answer for every problem. Yet you were introduced to the concept of uncertainty in scientific measurements. What is meant by "uncertainty"? How does uncertainty creep into measurements? How is uncertainty indicated in scientific measurements? Can uncertainty ever be completely eliminated in experiments? Explain.
