3 2006 Jupiterimages 3 What did the boy have to do to make his skateboard start moving faster? A. Push on the ground with his foot B. Push against the air with his hands C. Pull the skateboard up in the front 4 The balance is a system because it has A. parts working together to measure mass B. tools to measure length C. a process used in pulling 5 This is a picture of a mobile. How is this mobile a system? A. The stars, paper clips, and straws work together to balance. B. The stars, paper clips, and straws make a pretty picture. C. The stars do not balance on the mobile in the picture. SAISD, TEA 02 Science FMA Mar 11 Page 3

4 Left Right 6 The scale shown above is balanced. What action would lift up the pan that holds the apple? A. Taking a bite out of the apple B. Adding weights to the left pan C. Taking away weights from the right pan 7 A student removes one of the weights from the right pan. She replaces it with another weight that is of equal mass. What are the new positions of the pans in the balance? A. The pan holding the apple is higher. B. The two pans are still in balance. C. The pan holding the weights is higher.

5 Left Center of Beam Right 8 How many cubes do you think need to be placed on the end of the right side of the beam so that the beam is balanced? A. 3 cubes B. 9 cubes C. 15 cubes Systems Fulcrum moves Beam Balance (center) Equal-Arm Balance Fulcrum does not move No pails Stuff fits in the pails 9 Which characteristic needs to go in the center of the Venn Diagram? A. Both fulcrums move. B. Both have pails. C. Both can balance. SAISD, TEA 02 Science FMA Mar 11 Page 5

6 10 What is the correct mass for the cookie? (There are no hidden cubes in the pan.) A. 4 cubes B. 8 cubes C. 12 cubes 11 Students wanted to find out which food occupied the most space. To make a fair test, the students measured a mass of 10 cubes of food in each cup. The students drew the following results in their journal. Oat Cereal Sunflower Seeds Macaroni Peas Which food occupied the most space? A. Oat cereal B. Sunflower seeds C. Macaroni SAISD, TEA 02 Science FMA Mar 11 Page 6

7 Food Cubes Cereal Sunflower Seeds Macaroni Split Peas 12 Students recorded the mass of cupfuls of food in the above table. Use the information in the table to decide which line plot students would create to show where to place a sticky dot for macaroni. Macaroni A Number of Cubes Macaroni B Number of Cubes Macaroni C Number of Cubes SAISD, TEA 02 Science FMA Mar 11 Page 7

8 13 Which is the best question to ask about sound when using the materials below? A. What kind of sound does a wooden stick make on a wood floor? B. How does the pitch change when water is added to the bottles? C. How does the volume change when water is added to the bottles? SAISD, TEA 02 Science FMA Mar 11 Page 8

9 Use the following picture to answer questions 14 and cm Some images 2009 Jupiterimages 14 A student wants to make a high pitch sound. In order to make the highest pitch sound on the tool above, the student needs to move the cup closest to the A. 10 centimeter mark B. 15 centimeter mark C. 20 centimeter mark 15 Look at the string beam above. Which answer below is the best explanation of why the string beam is a system? A. When fingers carefully pluck the string it makes sound, like a musical instrument. B. When put together the meter stick, string, and cup make sound, like a musical instrument. C. The numbers on the meter stick make different sounds. SAISD, TEA 02 Science FMA Mar 11 Page 9

10 25 cm 10 cm Some items 2009 Jupiterimages 16 A student held a ruler at the edge of a desk with 25 centimeters hanging over the edge. The student plucked the tip of the ruler to make a sound (see the picture above). The student then held the ruler at the edge of a desk with 10 centimeters hanging over the edge. The student made a different sound. Which conclusion is most correct? A. The pitch was lower the second time because the length of the ruler was shorter. B. The pitch was higher the second time because the length of the ruler was shorter. C. The pitch was higher the second time because the width of the ruler was longer. 17 When you make sounds by plucking a rubber band, you make the rubber band move back and forth very quickly. This movement is called A. loudness B. pitch C. vibration SAISD, TEA 02 Science FMA Mar 11 Page 10

11 18 A student hits the bottles above with the same force to look for a high or low pattern of sound. What is the student testing? A. Pitch B. Loudness C. Vibration 19 If you tie a string around a doorknob, pull on the string slowly, and keep plucking it with your finger as you pull, what happens to the pitch? 20 The students made a list of ways to make the sound in the above instrument different. Which one will NOT change the sound? A. Change the length of the strings to be longer or shorter on the instrument. B. Move the place where you pluck the strings closer to the top or bottom of the instrument. C. Tighten the strings very tight. A. As you tighten the string, the pitch gets lower. B. The pitch stays the same. C. As you tighten the string, the pitch gets higher. SAISD, TEA 02 Science FMA Mar 11 Page 11
