physical properties of various substances. a. Differentiate between chemical and physical properties. b. Classify substances based on their chemical and physical properties (e.g., reacts with water, does not react with water, flammable or nonflammable, hard or soft, flexible or nonflexible, evaporates or melts at room temperature). c. Investigate and report on the chemical and physical properties of a particular substance. Objective 2: Observe and evaluate evidence of chemical and physical change. a

develops new knowledge. Standard 5: Students will understand that structure is used to develop classification systems. Objective 1: Classify <span class="highlight">based</span> <span class="highlight">on</span> observable properties. a. Categorize nonliving objects <span class="highlight">based</span> <span class="highlight">on</span> external structures (e.g., hard, <span class="highlight">soft</span>). b. Compare living, once living, and nonliving things. c. Defend the importance of observation <span class="highlight">in</span> scientific classification. d. Demonstrate that there are many ways to classify things. Objective 2: Use and develop a simple classification system. a

Science Benchmark Light is produced by the sun and observed on Earth. Living organisms use heat and light from the sun. Heat is also produced from motion when one thing rubs against another. Things that give off heat often give off light. While operating, mechanical and electrical machines produce heat and/or light. Standard 5: Students will understand that the sun is the main source of heat and light for things living on Earth. They will also understand that the motion of rubbing objects

sedimentary rock (i.e., preserved organisms, mineral replacement of organisms, impressions or tracks). c. Research locations where fossils are found <span class="highlight">in</span> Utah and construct a simple fossil map. Objective 2: Explain how fossils can be used to make inferences about past life, climate, geology, and environments. a.
