D Mystery Component 4, This answer is not correct The light bulb would be lit at an intensity of normal brightness if it. was Mystery Component 4,Page 5 of 35,Grade 4 Science Practice Test Answer Key.
Question 4,Reporting Category Scientific Process, Benchmark SC 4 1 1 Describe a testable hypothesis and an experimental procedure. Students are studying different kinds of plants and the conditions that they grow in They have planted. four kinds of young plants, Design and run an experiment that will show the effects of different amounts of water on these plants. Explanation of How to Use Simulation, The student can choose Little Medium or A Lot from the Amount of Water drop down menu. The student can choose Shade or Direct Sun from the Amount of Light drop down menu. After making these choices the student presses the green Start button An animation shows the. plants respond to the chosen conditions and the output table populates with the information shown. depending on the student s choices,Page 6 of 35,Grade 4 Science Practice Test Answer Key. Answer Key,For this item the response correctly, selects each Amount of Water once for a total of three trials.
the Amount of Light kept constant for each of the three trials. selects two different Amount of Water once for a total of two trials. the Amount of Light kept constant for each of the two trials. selects two different Amount of Water twice for a total of four trials. the Amount of light kept constant for each of the four trials. Example of Student Answer,Explanation of Correct Answer. In order to test the plants reactions to different amounts of water the student should test different. levels of water while keeping the amount of sunlight constant The student may test two or three levels. of water and some students may choose to repeat the trials more than once.

Answer Key B, A student notices that apples vary in sweetness and he wants to determine the cause. Which of the following should be done first when developing a scientific investigation based on this. observation,A Perform an experiment, This answer is not correct It is important to determine what is being testing before the experiment.
B Form a hypothesis, This answer is correct Forming a hypothesis is a first step in this inquiry. C Write a conclusion, This answer is not correct Writing a conclusion comes after experimentation and data analysis. D Construct a graph, This answer is not correct Constructing a graph comes after collecting the data to be graphed. Page 8 of 35,Grade 4 Science Practice Test Answer Key. Question 6,Reporting Category Scientific Process, Benchmark SC 4 1 2 Differentiate between an observation and an inference.
Answer Key C, A student performed an activity with soil and water The table below shows the kind of soil that was. added to each of two cans After the soil was added holes were made in the bottom of each can Then. a total of 200 milliliters of water was added to each can The water that dripped from each can was. collected for one minute, Which of the following is an observation in this experiment. A Sunlight heats water in clay faster than water in sand. This answer is not correct Sunlight is not part of this experimental procedure so this statement. cannot be an observation from this experiment,B Plants grow better in clay than in sand. This answer is not correct Growing plants is not part of this experimental procedure so this. statement cannot be an observation from this experiment. C Water flows through sand faster than through clay. This answer is correct An observation is information collected by the five senses In this. experiment the student collected the amount of water that flowed through lualualei clay and sand in. one minute The student was able to see that more water flowed through the sand than through the. clay in the same amount of time,D Insects are more active in sand than in clay. This answer is not correct Insects are not part of this experimental procedure so this statement. cannot be an observation from this experiment,Page 9 of 35.
Grade 4 Science Practice Test Answer Key,Question 7. Reporting Category Scientific Process, Benchmark SC 4 1 2 Differentiate between an observation and an inference. Answer Key A, A student makes a model of a volcano using paper and glue The student s teacher puts on goggles. and an apron The teacher pours baking soda and vinegar into the volcano model For 30 seconds a. white substance bubbles and expands out of the volcano. Which observation allows the student to conclude that a chemical reaction occurred. A A white substance bubbled and expanded, This answer is correct Expansion and bubbling are common pieces of evidence that a chemical. reaction is occurring,B Something happened for 30 seconds.
This answer is not correct The duration of the eruption provides no evidence that would allow the. student to conclude that the eruption was caused by a chemical reaction. C The teacher wore goggles and an apron, This answer is not correct The safety precautions the teacher took while performing the. demonstration provide no evidence that would allow the student to conclude that the eruption was. caused by a chemical reaction,D The volcano was made from paper and glue. This answer is not correct The materials used to make the volcano provide no evidence that would. allow the student to conclude that the eruption was caused by a chemical reaction. Page 10 of 35,Grade 4 Science Practice Test Answer Key. Question 8,Reporting Category Scientific Process, Benchmark SC 4 1 2 Differentiate between and observation and an inference. Answer Key D, Using only the senses of touch and smell a class is examining a substance.
Which of the following statements is most likely to be an inference about the substance. A The substance sticks to the fingers when touched. This answer is not correct This is an observation about the substance s behavior. B The substance has no odor, This answer is not correct This is an observation about the substance s smell. C The substance feels very soft when touched by the fingers. This answer is not correct This is an observation about the substance s texture. D The substance is powdered sugar, This answer is correct This is an inference about what the substance is based on the. observations,Page 11 of 35,Grade 4 Science Practice Test Answer Key. Question 9,Reporting Category Scientific Process, Benchmark SC 4 1 2 Differentiate between an observation and an inference. Answer Key B,Which statement about dolphins is an observation.
A Dolphins are the smartest animals, This answer is not correct This is an interpretation of dolphin behavior. B Dolphins can jump out of the water, This answer is correct This statement is an observation about dolphins. C Dolphins eat too many fish, This answer is not correct This is an opinion about dolphins and their environment. D Dolphins should be protected, This answer is not correct This is an opinion about how people should interact with dolphins. Page 12 of 35,Grade 4 Science Practice Test Answer Key.
Question 10,Reporting Category Scientific Process, Benchmark SC 4 2 1 Describe how the use of technology has influenced the economy demography. and environment of Hawai i,Answer Key D, A weather satellite can take a picture of a hurricane from space and send it to Earth in seconds. How would the people of Hawaii benefit by having a picture of a hurricane so quickly. A The picture can change the direction of the hurricane. This answer is not correct A picture can provide information about the size and location of a. hurricane but it cannot change the path of a hurricane. B People will know how long the hurricane will last. This answer is not correct A picture can provide information about the size and location of a. hurricane but it cannot predict how long a hurricane will last. C The effect of the hurricane on the beach will be changed. This answer is not correct A picture can provide information about the size and location of a. hurricane but it cannot predict how a hurricane will affect a beach. D People can be warned about the approaching hurricane. Grade 4 Science Practice Test Answer Key Page 5 of 35 Question 3 Reporting Category Physical Earth and Space Science Benchmark SC 4 6 2 Explain what is needed for electricity to flow in a circuit to create light and sound Answer Key B A student constructs the circuit shown Use the simulation to build the same circuit
