9. Name three things the speaker will do. (any three of the following are acceptable):

- The speaker will find out where the glimmering girl has gone. - The speaker will kiss the glimmering girl's lips. - The speaker will take the glimmering girl's hands. - The speaker will walk among long dappled grass. - The speaker will pluck the silver apples of the moon. - The speaker will pluck the golden apples of the sun. 10. Identify the mood of the poem and explain what the poet does to create this mood. Answers may vary, as long as they are supported by the poem. For example, students may respond that the mood is wistful. Students may then explain that the poet creates a wistful mood by stating in detail the intention and hopes of the speaker in pursuing the glimmering girl. The repeated imagery of things disappearing-the stars "flickering out" in line 6, the "glimmering girl" who fades in the air, the plucking of apples until "time and times are done"-also contributes to the wistful mood.

3 Explain how using a table is similar to using a double number line and how it is different.

Possible answer:

Double number lines and tables both show corresponding values in a proportional relationship. The ratios formed by corresponding values are always equivalent in both a table and a double number line. A double number line usually starts at 0 and increases incrementally. A table does not necessarily start at 0 and may not increase incrementally.

Interpreting Graphs of Proportional Relationships

The graph shows the cost of apples at a local market. Use the graph to answer problems 1?3.

1 What is the cost of 1 apple and of 3 apples? How do you know?

Possible answer: One apple costs $0.75, and 3 apples cost $2.25. The points (1, 0.75) and (3, 2.25) are on the graph. The x-coordinate of 1 corresponds to the y-coordinate of 0.75, and the x-coordinate of 3 corresponds to the y-coordinate of 2.25.

3 What does the point (2, 1.5) represent in this context? Possible answer: The cost of 2 apples is $1.50.

The graph shows Manuela's earnings for the number of hours she spends tutoring. Use the graph to answer problems 4 and 5.

4 How much does Manuela earn for each hour of tutoring? Explain.

Possible answer:

$10 per hour; Possible explanation: The graph goes through the point (1, 10). The y-coordinate associated with the x-coordinate of 1 is the constant of proportionality.

The graph shows the cost per pound of chicken salad. Use the graph to answer problems 9 and 10.

9 Randy claims that he can purchase 3.5 pounds of chicken salad for $23.50. Is he correct? Explain. No; Possible explanation: According to the graph, 3.5 corresponds to the point halfway between 22.5 and 30, and 23.5 is not halfway.

10 Explain how you can determine how much chicken salad may be purchased for $52.50. Possible answer: You can find the x-coordinate that corresponds with the y-value of 52.5 on the graph.

Acids, Bases, and Salts Cloze

Hydrochloric acid____ is a strong acid which can be used to clean rust off of steel. Sodium hydroxide, commonly known as lye, is a highly caustic base that is used to make soap. Both of these substances can cause severe burns if they come in contact with human skin. However, when these two very dangerous substances combine, they form ___table salt ____ and ___water____, both of which are completely harmless.

This process of combining acids and bases to make salts and water is known as ____neutralization___. In this reaction, the acid and base _____cancel_____ each other out.

There are many different kinds of salts. In general, a salt is a compound of positive and negative ___ions____. Often the positive ions are ___metals____ such as sodium and the negative ions are ___non-metals___ such as chlorine.

In the absence of water, these ions can form ___crystals______ which have a high ___melting____ point and are brittle. Many salts ___dissolve_____ readily in water.
