Procedure: Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.
Test variable (independent variable):

Outcome variable (dependent variable):

Select Intro to begin.
Once the simulation loads, you will drag the protractor onto the screen so that the 0 lines up with the dotted line in the center of the screen.
You will test all three materials in the bottom, blue half of the screen: air, water, and glass.
Record your observations of how the light rays interact as they pass from air, on the top of the screen, through the three materials on the bottom of the screen

Data:
Record the data from each trial in the data chart below. Be sure to fill in the chart completely.
Material
Interactions
List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen.
Evidence
Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.
Trial One
Air on top

Angle:
Index of refraction:
Air on bottom

Trial Two
Air on top

Angle:
Index of refraction:
Water on bottom

Trial Three
Air on top

Angle:
Index of refraction:
Glass on bottom

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.
Did your data support your hypothesis? Use evidence to explain.

Which material refracted the light rays the most: air, water, or glass?

Which material refracted the light rays the least: air, water, or glass?

How does density affect refraction?

Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.

Explain where you observe reflection, refraction, and absorption of light in your everyday activities

What is the biggest difference in central ideas and themes? question 1 options: themes are for stories with characters in them. there is only a central idea if it is explicitly (specifically, outright) stated in a story. central ideas are a main idea specific to the text, while themes are an universal lesson or moral. themes are only found in nonfiction, while central ideas are found in fiction. question 2 (1 point) which of the following is not a true statement about theme? question 2 options: mulitple themes can be found within a single text theme is usually inferred. the theme is always clearly stated by the author or a character. themes should be supported by evidence from the text. question 3 (1 point) what is indirect characterization? question 3 options: all details stated and implied that give the reader information about a character. details such as age, height, or hair color that give the reader information about a character. actions or dialogue said by a character that give the reader information about a character. the description an author gives about the character in the exposition. question 4 (1 point) which sentence best describes lizabeth's development in "marigolds"? question 4 options: lizabeth matures when she recognizes that love is more powerful than hate. lizabeth learns that sympathy and understanding come from recognizing the truth about other people. lizabeth changes her behavior after she recognizes that she needs to be a better example for her brother. lizabeth comes to recognize that the world is too barren to create lasting beauty. question 5 (1 point) how does the resolution of lizabeth's conflict in "marigolds" develop the theme? question 5 options: lizabeth recognizes that she has looked only at herself rather than at other people. lizabeth's destruction of miss lotte's flowers brings about justice over miss lotte's ill-treatment of the children. lizabeth's pursuit of adventure leads her to a more fulfilling life away from the shantytown. the camaraderie of lizbeth and joey creates meaning in both their lives. question 6 (1 point) which of the following quotations best exemplifies lizabeth's childish nature at the beginning of the story? question 6 options: "and one other thing i remember, another incongruency of memory - a brilliant splash of sunny yellow against the dust - miss lottie's marigolds." "by the time i was fourteen, my brother joey and i were the only children left at the house." "'hey, lizabeth,' joey yelled. he never talked when he could yell." "then i lost my head entirely, mad with the power of inciting such rage, and ran out of the bushes chanting madly, 'old witch, fell in a ditch, picked up a penny and through she was rich! '" question 7 (1 point) the story "marigolds" is told in a flashback. lizabeth recounts the details of the incident with miss lottie for the reader years after they have happened. how is this important to the development of lizabeth's character? question 7 options: lizabeth is older now and realizes that she may not have made the best decisions. lizabeth feels sorry for herself now and thinks that miss lottie is still angry. there were so many kids and so little to do, their behaviors should have been overlooked. all of these question 8 (1 point) lizabeth's "world had lost its boundary lines," when she overheard her father crying to her mother. what can we assume about the character of the father because of her reaction to this moment? question 8 options: we can assume that her father is a weak man. we can assume that her father shares his fears with his children and wife often. we can assume that her father is a proud and strong man and that his brokenness is a change in his character. we can assume that until this moment, her father has only cried to lizabeth but not to her mother which explains her surprise.
