1 Example Items Science 6 Science 6 Example Items are a representative set of items for the P. Teachers may use this set of items along with the test blueprint as guides to prepare students for the P. On the last page, the correct answer, content SE and SE justification are listed for each item. The specific part of an SE that an Example Item measures is NOT necessarily the only part of the SE that is assessed on the P. None of these Example Items will appear on the P. Teachers may provide feedback regarding Example Items. (1) ownload the Example Feedback Form and it. The form is located on the homepage of ssessment.dallasisd.org. OR (2) To submit directly, click Example Feedback after you login to the ssessment website. First Semester ode #: 3061

4 EXMPLE ITEMS Science 6, Sem 1 1 s a student holds a glass of iced tea, the temperature of the tea increases and the temperature of his hand decreases. Will the temperature of his hand continue to change? No, because all the heat will flow from his hand to the tea. Yes, because the ice will cause the temperature of the tea to decrease. Yes, because heat will continue to flow back and forth between both objects. No, because heat will stop flowing when both objects reach the same temperature. Use the table to answer the next question. Properties of Unknown Substances Substance Malleability Electrical onductivity Luster High High Yes High Medium Yes Low Medium Yes Low Low No 2 Which substance is a metalloid? 3 Which statement is true? The Earth s crust is made almost entirely of just a few elements. The Earth s crust is made almost entirely of a single element. The Earth s crust is made of approximately equal parts of all the elements. The Earth s crust is made of approximately equal parts of about half the elements. allas IS - Example Items

5 EXMPLE ITEMS Science 6, Sem 1 4 Wind energy is harnessed by using a wind turbine. What type of energy transformation takes place in a wind turbine? Wind hemical hemical Electrical Mechanical Electrical Electrical Mechanical 5 Which statement is correct? symbol represents a compound and a formula represents an element. The Periodic Table has exactly 108 known compounds. n element contains atoms of different compounds. compound contains atoms of different elements. 6 teacher mixed baking soda and vinegar in a plastic bottle. Then she quickly stretched a balloon over the mouth of the bottle. The balloon inflated, which indicated a chemical change because a gas was produced to inflate the balloon a liquid was produced to inflate the balloon a precipitate was produced to inflate the balloon an explosion occurred to inflate the balloon allas IS - Example Items

9 EXMPLE ITEMS Science 6 Key, Sem 1 Item# Key SE Process Skills SE Justification E Verify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting. ompare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability. Recognize that a limited number of the many known elements comprise the largest portion of solid Earth emonstrate energy transformations E E E ifferentiate between elements and compounds on the most basic level. Identify the formation of a new substance by using the evidence of a possible chemical change such as production of a gas, change in temperature, or production of a precipitate. Test the physical properties of minerals, including hardness, and luster. esign a logical plan to manage energy resources in the home. ebate the advantages and disadvantages of using coal, oil, and natural gas. Know that an element is a pure substance represented by chemical symbols. alculate density to identify an unknown substance. Investigate methods of thermal energy transfer, including conduction, convection, and radiation.
