1 FORMATIVE MINI ASSESSMENTS Third Grading Period February 1-5 STUDENT NAME DATE Science Grade 5 Read each question and choose the best answer. Be sure to mark all of your answers. Sand, small pebbles, iron filings, and sawdust 1 Which tool would be best to use to remove iron fillings from the mixtures? A C B D SAISD 05 Science FMA February 10 Page 1

2 2 A student looked under a microscope at some crystals that were created as a result of evaporation. Crystal shape can be used as a means of classification because it is a F solution G physical property H mixture J chemical property 3 In an activity, 20 grams of salt are dissolved in 70 grams of pure water. The water is then heated on a hot plate. When the water evaporates completely, how much salt will be left? A 0 grams B 18 grams C 20 grams D 22 grams SAISD 05 Science FMA February 10 Page 2

3 4 Looking at the thermometers below, a possible conclusion that can be drawn is that Thermometer A Thermometer B 5 In an experiment, salt and sand are mixed together. Which of these procedures could be used to most easily separate the salt from the sand? A Stir mixture into a glass of water Pour the mixture in the glass through a filter Evaporate the water B Pour the mixture onto a piece of paper Brush the mixture into a pile Drag a magnet through the pile C Put the mixture in a pan Heat the pan for 10 minutes Let the hot mixture cool slowly F thermometer A is showing the boiling point of water in degrees Celsius. Thermometer B is showing the freezing point of water in degrees Celsius. G thermometer A is showing the freezing point of water in degrees Celsius. Thermometer B is showing the boiling point of water in degrees Celsius. H thermometers A and B are showing the freezing point of water in degrees Celsius. J thermometer A is showing the temperature of a sunny day in Texas in degrees Celsius. Thermometer B is showing a cold winter day in Texas in degrees Celsius. D Spread the mixture into a thin layer Look at the mixture through a magnifying glass Separate the crystals with a pin SAISD 05 Science FMA February 10 Page 3

4 6 Which of the following thermometers shows the boiling point of water in a pan? F 7 White sand and kosher salt are both white powders. When mixed together, they look like one white powder. Which of these would be best to use to separate the white sand from the kosher salt? A A magnifying glass and a needle to physically separate the powders from each other B Heat to melt one of the powders to a liquid form to be poured off C A magnet to attract the white sand and not the salt D A cup of water to place the powders in and observe which will be filtered and which will dissolve G Syringe System H tip plunger barrel 2010 Clipart.com J 8 The tool above is used in scientific laboratories to draw liquids out of tall graduated cups. It is called a syringe. The syringe can be considered a system because F it has structures that interact G it has processes that cause change H it has cycles that repeat themselves J it is a tool that helps do a job SAISD 05 Science FMA February 10 Page 4

5 Solution Trail 1 Trial 2 Trial 3 50 ml water 45 min 43 min 47 min 50 ml water and 5 g salt 70 min 75 min 82 min 50 ml water and 10 g salt 120 min 125 min 119 min 9 The table shows the time it took to freeze water in two different salt solutions with different salt content. According to the table A freezing rates are the same in each trial B water with more salt takes longer to freeze C water loses heat at a rate of 1 C per minute D salt dissolves more quickly in small amounts of water 10 Using only the equipment above, which plan below is the best test to answer the question, What kind of water evaporates faster, saltwater or freshwater? F Pour some water in each beaker. Put one spoonful of salt in each beaker. Time how long it takes for the water in each beaker to evaporate. G Pour 50 milliliters of water in each beaker. Put one spoonful of salt in each beaker. Place both beakers under the lamps and time how long it takes for the water in each beaker to evaporate. H Pour 50 milliliters of water in each beaker. Put one spoonful of salt in one beaker. Place both beakers under the lamps and time how long it takes for the water in each beaker to evaporate. J Pour water in one beaker. Put one spoonful of salt in one beaker. Place both beakers under the lamps and time how long it takes for the water in each beaker to evaporate. SAISD 05 Science FMA February 10 Page 5

6 MATTER Solid Liquid Gas Keeps its shape when it changes containers Takes the shape of its container Fills the shape of its container L Orange Juice Air 11 According to the chart above, which of these objects could be placed in box L? A Saltwater B Gravel C Chocolate milk D Oxygen SAISD 05 Science FMA February 10 Page 6

7 12 Which sentence below best explains the expected change of a balanced pan in the following experiment? A student placed a rock with the mass of 250 grams in the right pan and a toy car with the mass of 300 grams in the left pan. F The left pan will drop because the rock is 50 grams heavier. G The right pan will drop because the toy is 50 grams heavier. H The left pan will drop because the toy is 50 grams heavier. J The right pan will drop because the rock is 50 grams heavier. 14 Which procedure is BEST to test the hypothesis that salt dissolves faster in hot water than cold water? F Fill two equal containers with water. Heat one until it boils. Add equal amounts of salt to the hot and cold containers and record how long it takes the salt in each of them to dissolve. G Fill two equal containers with water. Heat one container until it boils. Add equal amounts of sugar to one and salt to the other. Record how long it take each of them to dissolve. H Fill two equal containers with water. Heat both of them until they boil. Add salt to both and record how long it takes the salt in each of them to dissolve. J Fill two equal containers with water. Heat both of them until they boil. Add equal amounts of sugar to one and salt to the other and record how long it takes each of them to dissolve. 13 Students wanted to add Kool Aid to a pitcher of water. Students continued to stir as they added one scoop of powdered Kool Aid to the water at a time. Students checked after each scoop to see if all of the Kool Aid dissolved. After a time, Kool Aid would no longer dissolve into the water and crystals started to appear at the bottom of the pitcher. The best explanation for this is that A the solution was red B the solution was diluted C the solution was powder D the solution was saturated SAISD 05 Science FMA February 10 Page 7
