4. The diagrams show liquid water changing to water vapor in four different situations. Which observation would be evidence that the water is undergoing a phase change? A.Waves form on the top of the pond. B.Water soaks into the wet sand. C.The water splashes out of the swimming pool. D.The water level in the glass of water decreases.

6. The diagram below uses letters A, B, C, D and E to represent processes occurring in a water cycle. In the chart on the next slide, identify the process that is occurring at each letter in the diagram. E

7. LetterProcess that is occurring A B C D E Use the Pen Tool to write your answers in the boxes. Click in each box to see if you are correct. Evaporation Condensation Precipitation Runoff Accumulation

8. Which is the best example of evaporation? Araindrops freezing B an ice cube melting C a puddle drying in the sun D a sponge soaking up water

9. C. a puddle drying in the sun

10. Heavy rains in an aquifer’s recharge zone cause rivers and streams to flood. How will this most likely affect the aquifer? A The total water volume in the aquifer will increase. B The water coming from natural springs will decrease. C The water level in the aquifer will decrease. D The amount of water use by humans will increase.

11. A The total water volume in the aquifer will increase. The water will seep (go) into the aquifer causing it to fill up. This is an example of GROUND WATER.

12. Sand, small pebbles, iron filings, and sawdust What tool can be used to remove iron filings from the mixture?

13. A Magnet

14. A student combined sugar, water, cranberry juice and ice cubes in a pitcher to create a solution. How do you know that a solution is a type of mixture?

15. 1.Made up of 2 or more items. 2.Keeps it own properties 3.Can be separated

16. Which of these is a mixture? A SaltC Lemonade B WaterD Sugar

17. Lemonade

18. Which picture below represents a mixture?

19. There is more than one living organism in the picture.

20. Which set of pictures shows what happens to a glass of salt water when it is left out on a counter for several weeks? 1.C → D → A → B 2.A → C → B → D 3.B → A → C → D 4. D → B → A → C

21. 2.A → C → B → D

22. The picture below shows a ringing bell inside a vacuum jar. As air is pumped from the vacuum jar, the sound level of the ringing bell will decrease until it can no longer be heard. This happens because air must be present in the jar in order for (1) sound to be transferred (2) electricity to flow through the wires (3) the rubber to seal the jar (4) the bell clangor to vibrate

23. (1) sound to be transferred

24. A new substance is found. The substance is extremely lightweight. Most remarkably, it will expand and fill each of the containers below. Which type of matter is this new substance? A. gas B. solid C. liquid

25. A. gas

26. Which of these will change solid iron to a liquid? A Raising the air pressure B Increasing its temperature C Crushing the solid iron D Adding water to the iron

27. B Increasing its temperature

28. Which of the diagrams best shows the arrangement of molecules in a solid? A B D C

29. C

30. The picture shows a puddle on the sidewalk Which best describes what is happening to the water? F As heat is added, the water will melt. G As heat is removed, the water will freeze. H As heat is removed, water vapor will condense. J As heat is added, the water will evaporate.

31. The sun is shining and the current temperature is 27  C. This indicates it is warm outside and could possibly get warmer.

32. An air hose extends above and below the surface of the water. Which statement explains why the air hose looks broken at the surface of the water? A. Light is refracted as it moves from air to water. B. Light is reflected as it moves from air to water. C. Light is absorbed as it moves from air to water. D. Light is destroyed as it moves from air to water.

33. A. Light is refracted as it moves from air to water.

34. This is a picture of the Northern Lights in Alaska. Why is this a good example of both refraction and reflection?

35. Reflection: The light show in the sky is bouncing off the lake or river below making it look like there is another light show in the water. Refraction:The light traveling through the atmosphere is bending and creating different colors. Example: light traveling through a prism.

36. What causes a blue block to appear blue in the sunlight? A. The block absorbs all blue light. B. The block bends (refracts) all blue light. C. Only blue light is reflected by the block. D. Only blue light passes through the block.

37. Only blue light is reflected by the block.

40. Moving water in a river is considered a renewable resource because it

41. can be recycled by nature over time

42. Mark found a metal object under his desk. How can he determine if the object is made of iron?

43. He can place the object next to a magnet to see if it is attracted. Iron is attracted to a magnet.

44. Electric energy flows through the wire filament in a light bulb. The energy flow causes the wire to glow and give off light. What is the source that helps this light come on? A. sound B. wire C. battery D. magnetic

45. C. battery

46. Two juice containers are in a cooler. One is plastic and one is metal. The metal can feels colder than the plastic bottle. Students place a thermometer in each container. They find that the juices in the bottle and in the can are the same temperature. Why does the can feel colder than the bottle? A. The metal can holds colder juice than the plastic bottle. B. Plastic is a better conductor of thermal energy than metal. C. Metal is a better conductor of thermal energy than plastic. D. The outside of the metal can is drier than the plastic bottle.

47. C. Metal is a better conductor of thermal energy than plastic.

48. Students build the complete circuit shown to create a noise with a buzzer. After building the circuit, the students close the switch, but the buzzer does not buzz. What are 2 possible reasons the buzzer will not work?

49. 1.The battery is dead or does not have enough power to cause the buzzer to work. 2.There could be a loose connection somewhere along the circuit line.

50. In Diagram 1, two identical magnets (Y and Z) appear as shown. The magnets can only move up and down in a clear plastic tube. In Diagram 2, a third identical magnet (X) is going to be added What will happen when the third identical magnet is placed in the top of the clear plastic tube? A. Magnet X will flip over. B. Magnet X will be attracted to Magnet Y. C. Magnets (X, Y and Z) will move closer together so that all touch. D. Magnets (X, Y and Z) will form a stack with space between the magnets.
