Light is not produced at all. If all of the energy were transferred, the ball would not have enough energy to bounce back away from the wall; and if none were transferred, a sound would not be produced.  \nItems 5–6  \nDomain: Earth and Space Science  \nPhenomenon: A student on the way to school in January observes that some icy roads had been treated with sand and others with salt.  \nItem 5  \nUIN: 518047_01  \nItem Type: Multiple Choice  \nStandards alignment: DCI: ESS3.B; SEP: EAE; CCC: C and E  \nKey: D  \nRationale:  \nThe table shows that tires skid less because sand helps the tires grip the road, and sand is also less expensive than salt. The table also states that sand does not melt ice and has some environmental impacts, making answers A, B, and C invalid.  \nItem 6  \nUIN: 518047_02  \nItem Type: Technology Enhanced  \nStandards alignment: DCI: ESS3.B; SEP: CEDS; CCC: C and E  \nSR/AT/Paper Key: B; A; B  \nKey: A correct response will look like this:  \nRationale:  \nThe table shows:  \nSnow-covered roads: Sand helps the tires grip the road and salt does not help melt snow-covered roads when the air temperature is below 10°F.  \nIcy roads with air temperature of 20°F: Salt works when the temperature is above 10°F.  \nIcy roads with air temperature of 5°F: Sand would be better, since the temperature is below 10°F, and salt only works when the temperature is above 10°F. Sand helps the tires grip the road.  \nItem 7–9  \nDomain: Earth and Space Science  \nPhenomenon: At night, a street light appears bigger and brighter than other street lights on the same street, just like some stars in the sky.  \nItem 7  \nUIN: 518019_05  \nItem Type: Multiple Choice  \nStandards alignment: DCI: ESS1.A; SEP: AID; CCC: S, P, and Q  \nKey: B  \nRationale:  \nTable 1 shows street light X is closest to the student (1 km), and it appears the brightest (medium) . Answer A is the opposite, therefore invalid.  \nTable 2 shows similar information as Table 1 for the relative distance and brightness of stars. The farther away the star is, the less brigh","cbCaisM21ZmEViJN","https://ap.wps.com/l/cbCaisM21ZmEViJN","pdf",573578,"English","# Items 1-2: Physical Science\n## Electric current produces motion\n\n# Items 3-4: Physical Science\n## Energy and bouncing distance; sound and light conversion\n\n# Items 5-6: Earth and Space Science\n## Sand vs salt on icy roads and temperature effects\n\n# Items 7-9: Earth and Space Science\n## Brightness and apparent size of street lights and stars\n\n# Items 10-12: Earth and Space Science\n## Earthquake risk by region","[{\"question\":\"What is the key physical science concept in Items 1–2?\",\"answer\":\"An electric current can produce motion.
