Example Items Science 6

Transcription

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 the ssessment website (assessment.dallasisd.org). OR (2) To submit directly: Login to the ssessment website. Under News in the left-hand column, click on Sem 2 Example Items ownload. bove the subjects, click on Example Feedback Form.

4 EXMPLE ITEMS Science 6, Sem 2 1 When two oceanic plates collide, what geological formation occurs? Faults Ridges Valleys Volcanoes 2 log has decayed in a forest. The log is considered biotic because it was once a living organism occupied space in the forest stored rainwater for birds to drink became a habitat for many insects 3 ll organisms are multicellular unicellular either multicellular or unicellular unicellular at birth and multicellular during growth 4 What has a composition similar to a dirty snowball and travels around the Sun in elliptical orbits? steroid omet Galaxy Meteor 5 What processes change rock into sediments and begin the formation of sedimentary rocks? Pressure and heat Melting and cooling Weathering and erosion ompaction and cementing allas IS - Example Items

5 EXMPLE ITEMS Science 6, Sem 2 6 Mikayla needs to lift a 200 N load. Using two pulleys, how many newtons of force does she need to lift the load? 100 N 150 N 200 N 400 N 7 teacher uses a swinging pendulum to explain energy Which statement best explains the relationship between potential and kinetic energy at position 1? Kinetic and potential energy are equal. Potential energy is greater than kinetic energy. Kinetic energy has been totally converted into potential energy. Potential energy has been totally converted into kinetic energy. allas IS - Example Items
