1 Properties of Matter Review

2 Janice found two sea shells when she went to the beach. They appear to be almost the same size, but they have different shapes. How could she figure out if their volume is the same? A.Weigh each one on a scale to see which is heaviest. B.Fill each one with water to see which will hold the most. C. Drop each one in a beaker of water to see which raises the water level the most. D. Measure the length of each one with a measuring tape to see which is longest.

A.The air is a gas that cannot be compressed by any means. B. The air is a gas that always forms a round shape when compressed. C. The air is a gas that expands to evenly fill the space inside the balloon. D. The air is a gas that will flow evenly and steadily from inside the balloon if punctured.

5 Jacob found a piece of a broken glass bottle. He picked it up and made these observations about it: 1. No color (clear) 2. Makes scratches on wood 3. Has a bumpy surface 4. Broke when I dropped it He thinks the glass is a solid and most of his observations could only apply to a solid. Which one of his observations could possibly apply to a solid, a liquid or a gas? A.1 B.2 C.3 D. 4

6 Dan brought some chocolate chips in a plastic container with his lunch one day. He decided to save them and eat them while he waited for the bus after school. All afternoon his lunch bag sat on the warm windowsill in his classroom. When he finally took the container out after school, the chocolate chips had turned into a hard chunk of chocolate shaped like the bottom of the container. What happened to his chocolate chips? A.They started as a solid, melted, and then became solid again. B. They changed from a solid to a gas before becoming solid once again. C. They were a cool solid to start, then became a warm solid before cooling again. D. They went from being a hard solid to a gas, a liquid, and then to a hard solid again.

7 Lorenzo wants to mail a breakable birthday present to his friend. He has some crumpled newspaper and some crumpled tissue paper that he could use as packing material. Either one of them would protect his present from breaking. He needs to figure out which type of packing material will weigh less, since the amount of postage he has to pay is based on how much his package weighs. What would be the BEST way for him to figure out which one to use? A.Weigh a newspaper, weigh a package of tissue paper, and see which weighs more. B.Weigh a crumpled piece of newspaper, weigh a crumpled piece of tissue paper, and see which weighs more. C.Put ten pieces of crumpled newspaper in the box and weigh it, repeat with ten pieces of crumpled tissue paper, and see which weighs more. D. Pack the box with crumpled newspaper and weigh it, then pack it with crumpled tissue paper, and see which weighs more.

8 If two objects balance like the ones shown below, what must be true? A.Object A has more mass than object B. B. Both objects have the same mass. C. Object A has more volume than object B. D. Both objects have the same volume.

9 Nathan went swimming at the lake over the weekend. While he was playing on the shore, he found a small chunk of cement and a stick, which appeared to be the same size. What would be the best way for Nathan to compare the volume of the stick and of the chunk of cement? A. Place them in a bucket of water and see which one raises the water level the most. B. Place them each on a scale and see which one weighs more. C. Use a ruler to measure the length of each of the objects D. Throw them in the lake and see which one will sink.

10 Maria and Lucy are making peanut butter sandwiches. They learned at school that a substance may be a solid, a liquid or a gas. Maria thinks the peanut butter is a solid, but Lucy thinks it is a liquid. What would be the best way to test it to see if it is a liquid? A.Heat it to see if it gets softer. B. Try to pour it out of the jar. C. Press it to try to make it take up less space. D. See if its volume increases in the freezer.

11 Both cookies and gelatin desserts are solids although their textures are very different. What do they have in common that makes them solids? A.They both may be eaten. B. They both can move around in a container. C. They both keep their own shape. D. They both are made of solids such as sugar.

12 George's science teacher has a mixture of table salt and iron filings. Which of the following would be the best way to separate the salt and the iron filings? A. use a magnet to pull the iron filings from the salt B. add food coloring to the mixture to make the salt change color C. pour them into a beaker of water and see if the iron filings float D. heat up the mixture to see if the salt or the iron filings will burn away

13 Carrie has a container that contains thousands of mixed glass beads and iron beads of different shapes and sizes. Which of the following is the best way to separate them? A.The glass beads will float, so she could add water to the container and the glass will float to the top. B. The iron beads are magnetic, so she could separate the glass from the iron with a strong magnet. C. The iron beads might be heavier, so she could shake the container until the iron beads settle to the bottom. D. The iron beads are smaller, so she could pour the beads through a strainer and the glass beads will separate.

14 Imagine you have a bucket of saltwater. Which of the following would be the best way to remove the water so that you're left with only salt? A.Stir the saltwater for a long time. The salt will form a crystal. B. Leave the saltwater to sit for a long time. The salt will settle to the bottom. C. Boil the saltwater. The water will evaporate and only the salt will remain. D. Freeze the saltwater. The water will sink to the bottom and the salt will rise to the top.

15 Abdul uses sugar cubes to sweeten his tea. He wonders whether stirring his tea will make the sugar cube dissolve faster or slower. If Abdul stirs his tea, what effect does it have on the rate at which the sugar cube dissolves? A.The rate that the sugar cube dissolves will speed up. B. The rate that the sugar cube dissolves will slow down. C. The rate that the sugar cube dissolves will remain the same. D. The rate that the sugar cube dissolves will slow down and then stop.

16 Which of the following solids will not dissolve in boiling water? A. baking soda B. sand C. sugar D. sugar

17 Imagine that you have four buckets full of dark, muddy water. One bucket is frozen, one bucket is boiled, one bucket is shaken up, and one bucket is passed through a paper filter. Which bucket is most likely to become lighter in color? A.The frozen bucket, because the mud separates from the water. B. The shaken bucket, because shaking causes the mud to dissolve. C. The boiled bucket, because the dirt in the muddy water evaporates. D. The filtered bucket, because larger particles of dirt were strained out.

18 Jason has a mixed container of iron pellets, foam pellets, glass pellets, and salt pellets. He needs to do the following things to separate these solids: A. Add water to the container and stir to dissolve the salt. B. Heat the water until it evaporates and leaves the salt. C. Remove the iron pellets with a magnet. D. Collect the floating foam pellets and the glass ones that have stuck to the bottom. Which answer choice puts these steps in the correct order? A.A, C, B, D B.C, A, D, B C.D, A, B, C D. B, D, C, A

19 Imagine a thick ten-kilogram block of soap and a thin ten- kilogram sheet of soap. Which answer correctly explains which will dissolve first when they are both placed underwater? A.The sheet will dissolve first because it has more surface area. B.The sheet will dissolve first because it has less mass than the block. C.The block will dissolve first because it is less spread out than the sheet. D. The sheet and the block weigh the same, so they will take the same amount of time to dissolve.

20 Kayla wants to know if a sugar cube in a bowl of water will dissolve more quickly if it is stirred with a spoon than if it is left alone. Which answer explains the effect that stirring will have? A.Stirring makes the sugar move around, and it dissolves more slowly because it is not staying still. B.The sugar will dissolve more slowly because the movement of the water makes it stick together. C.The sugar dissolves more quickly because the motion of the spoon creates heat, which melts the sugar. D. When the sugar is stirred, more surface area will come into contact with the water, so the sugar dissolves more quickly.

21 Sam drops a sugar cube weighing one gram in a cup of cold water and lets it sit until the sugar cube dissolves. Malcolm adds one gram of powdered sugar to a cup of hot water and stirs it with a spoon. Rosa adds a one-gram packet of sugar granules to a cup of cold water and stirs it with a spoon. Angela adds a sugar crystal weighing one gram to a cup of hot water and does not stir it. Whose sugar is most likely to dissolve the fastest, and whose is slowest? A.Malcolm's sugar dissolves fastest, and Sam's dissolves slowest. B. Rosa's sugar dissolves fastest, and Malcolm's dissolves slowest. C. Sam's sugar dissolves fastest, and Angela's dissolves slowest D. Angela's sugar dissolves fastest, and Rosa's dissolves slowest.
