In Figure 1, the light waves travel in straight lines until they meet the surface of the mirror. Because the mirror is curved, all the light waves reflect off the surface of the mirror in paths that are parallel to one another.  \nItem 2  \nUIN: 1908M016_01  \nItem Type: Multiple Choice  \nStandards Alignment: DCI: PS4.B; SEP: AQDP; CCC: C and E  \nKey: A  \nRationale: Figure 2 shows that the light waves that reach the lens pass through the lens, so the light waves are transmitted through the lens and not reflected by the lens.  \nAnswer B is invalid because the lens does not affect the color of the light waves.  \nAnswer C is invalid because the lens does not affect the distance the light waves travel.  \nAnswer D is invalid because the lens does not actively transfer matter from one side to the other.  \n1 The UIN (Unique Identification Number) can be used to find an item in the New Jersey Digital Item Library ( [https://nj.digitalitemlibrary.com/](https://nj.digitalitemlibrary.com/))  \nItem 3  \nUIN: 1908M016_05  \nItem Type: Technology Enhanced  \nStandards Alignment: DCI: PS4.A; SEP: OECI; CCC: SFSR/AT/Paper Key: Lighthouse: B, C; Foghorn: A, C Key: A correct response will look like this:  \nRationale: Row 1: Light waves consist of electromagnetic radiation and do not require a medium through which to travel. The foghorn uses sound waves that require a medium through which to travel. In this case, the sound waves are transmitted by the compression and expansion of air particles. Row 2: Figure 1 and Figure 2 show that the signal system used by lighthouses is designed to focus light waves in a specific direction. However, sound waves are emitted by the foghorn in all directions. Row 3: Light is a form of energy. The signal system used by a foghorn emits sound, which is also a form of energy.  \nItems 4-7  \nDomain: Life Science  \nPhenomenon: Bat activity can be affected by artificial lighting.  \nItem 4  \nUIN: 1908M022_01  \nItem Type: Multiple Choice  \nStandards Alignment: DCI: LS2.C; SEP: AQDP; CCC: C and E  \nKey: D  \nRationale: The data show that, of the colors tested, red light has the least effect on the bats’ behavior compared with when no artificial light is present.  \nAnswer A is invalid because the data in Figure 1 show that green light affects bat activity but do not explain why this happens.  \nAnswer B is invalid because Figure 1 shows data on the number of times bats passed by different colored lightsand does not include data on how bats can distinguish green and red insects.  \nAnswer C is invalid because the data in Figure 1 do not provide information about how the combination of green and red light affects bat activity.  \nItem 5  \nUIN: 1908M022_02  \nItem Type: Technology Enhanced  \nStandards Alignment: DCI: LS1.D; SEP: PACI; CCC: C and ESR/AT/Paper Key: Box Y: C; Box Z: B  \nKey: A correct response will look like this:  \nRationale: The independent variable is the color of light, which the researchers manipulate and is indicated on the x-axis of Figure 1. Light acts as a stimulus to the bats’ nervous system, which coordinates the behavioral response of the bats to the light.  \nItem 6  \nUIN: 1908M022_03  \nItem Type: Multiple Choice  \nStandards Alignment: DCI: LS1.D; SEP: EAE; CCC: S and SM  \nKey: A  \nRationale: Student 1’s claim explains how the nervous system coordinates a response to a stimulus by sending messages to the muscular system.
