1 SCI-5 MES- Lamb Variables, measurement and scientific method Exam not valid for Paper Pencil Test Sessions [Exam ID:2NFVGJ 1 According to this chart, which two materials conducted the least amount of heat? A Bricks and Water B Rocks and Glass C Wood and Bricks D Water and Wood

2 2 Which month has the least rain? A August B July C October D September 3 When conducting an experiment, a careful guess is called a A result B hypothesis C variable D constant 4 The larger the mass of a planet, the greater the pull of gravity on that planet s surface. According to the information in the chart, which of these planets has a mass closest to the Earth s mass? A Mars B Jupiter C Venus D Mercury

3 5 A science class went on a field trip and made a graph of the different kinds of insects that they saw. Which group of insects was seen the most? A B C D

6 The science class wants to find out which of these two cars is the fastest. All variables should be kept the same EXCEPT A the height of the ramp they use. B the weight of the cars being tested.

The class wants to know what will happen to these healthy plants by the end of the week. What is the independent variable?

4 6 The science class wants to find out which of these two cars is the fastest. All variables should be kept the same EXCEPT A the height of the ramp they use. B the weight of the cars being tested. C the amount of force used to push the cars. D the amount of friction on the ramp. 7 In the experiment pictured, the plants are fed once daily for one week. The class wants to know what will happen to these healthy plants by the end of the week. What is the independent variable? A How much water the plants are given each day B What the plants are watered with each day C How long it takes the plants to die D The number of times the plants are watered each day 8 A student tested the Jumbo White Marshmallows and the Gooey-Tooey Marshmallows to see which type melted the fastest. What is the dependent variable? A Taste of marshmallows B Melting time of marshmallows C Brand of marshmallows D Color of marshmallows

A Slope of the hill B Amount of water C Size of the rocks D Type of dirt 10 A student designed an investigation to

5 9 In an experiment, Jackson tested to see how the size of rocks affects the amount of dirt that washes away when water flows downhill. Which variable was manipulated? A Slope of the hill B Amount of water C Size of the rocks D Type of dirt 10 A student designed an investigation to test the effect of light color on plant growth. What was the manipulated (independent) variable in the investigation? A Height of plant B Size of pot C Color of the bulb D Hours of light

6 11 This data was collected in a 5th grade class experiment. The students had four different bean plant groups which they exposed to various amounts of light. What can be concluded from this data? A The plants that were given three hours of light per day died. B Bean plants grow best when given 9 hours of light per day. C Bean plants need as much sunlight per day as possible. D The plants given 9 hours of light per day grew very large beans. 12 Students conducted an experiment to determine if the rate of stirring would affect the speed that salt dissolves in water. Students used three identical cups with 100 ml of water in each cup. One tablespoon of salt was added to each cup. Cup 1 was stirred rapidly, cup 2 was stirred slowly, and cup 3 was not stirred at all. After 2 minutes, students observed: - Cup 1 had no salt remaining - Cup 2 had some salt remaining - Cup 3 had most of its salt remaining Which of the statements represent a conclusion students could draw from the experiment? The slowest rate of stirring had the greatest effect on the speed of the salt dissolving in the water. The rate of stirring had no effect on the salt dissolving in the water. The experiment did not work and no conclusions can be made. The fastest rate of stirring had the greatest effect on the salt dissolving in the water.

13 According to the data collected and recorded in the graph below, which material conducted the most heat? A Glass B Water C Bricks D Rocks 14 Which item is an inference?

7 13 According to the data collected and recorded in the graph below, which material conducted the most heat? A Glass B Water C Bricks D Rocks 14 Which item is an inference? A I smell cookies baking in the oven. B It must be time to buy new tires. C I saw 6 students running in the hallway. D I hear a dog barking. 15 A group of students was preparing an activity to determine whether certain materials will float or sink when placed on water. Before the experiment started, one student said, I think the sponge will float. This statement was A a conclusion B an observation C a fact D a prediction

8 16 Which hypothesis best matches this question? A If migration is a major part in the bird's life, then the bird will live longer. B If birds migrate, then the areas they fly to will get new prey. C If an experiment is done on bird migration, then an area's natural resources will decline. D If birds are tagged, then their location can be documented as they migrate over time. E If a location is known for having migratory birds, then it is a good place to do experiments. 17 Students conducted an experiment to see if the temperature of water affects how fast salt will dissolve. Select the correct hypothesis for the experiment above. Hot water causes the salt to dissolve faster. The graph shows that heat makes the salt dissolve faster. If the temperature is increased, then the salt will dissolve faster. When the heat was added, the salt dissolved faster. 18 When conducting an experiment, a careful guess is called a A variable B hypothesis C constant D result

9 19 A student observes a mineral that is colorless and harder than glass. Based on the chart, which mineral is the student observing? A Garnet B Amphibole C Feldspar D Quartz

10 20 About how much longer is the jackknife clam than the razor clam? A 7 centimeters B 10 centimeters C 12 centimeters D 5 centimeters 21 What is the volume of liquid in the graduated cylinder? A 21 ml B 20 ml C 22 ml D 19 ml

11 22 What is the volume of liquid in the graduated cylinder? A 23 ml B 20 ml C 24 ml D 22 ml 23 What is the mass of the marker? A 14 grams B 114 grams C 10 grams D 4 grams

12 24 Which balance shows an object with a mass greater than 200 grams? A B C D 25 By looking at the picture, which is an inference? A The girl is wearing a dress. B The boy on the left is sitting. C The boy on the right is standing. D The girl was reading a book.
