** Science (NEW), Grade 3, STRAND 1: INQUIRY PROCESS **
Standard 1. Conduct observations, ask questions and form predictions.
 * 1.1. Formulate relevant questions about the properties of objects, organisms, and events of the environment using observations and prior knowledge.
 * 1.2. Predict the results of an investigation based on observed patterns, not random guessing.

Standard 2. Design and conduct controlled investigations.
 * 2.1. Demonstrate safe behavior and appropriate procedures (e.g., use of instruments, materials, organisms) in all science inquiry.
 * 2.3. Conduct simple investigations in appropriate grade-level curriculum.
 * 2.5. Record data in an organized and appropriate format (e.g., t-chart, table, list, written log).

Standard 3. Analyze data, draw conclusions and evaluate scientific information.
 * 3.2. Construct reasonable interpretations of the collected data based on formulated questions.
 * 3.3. Compare the results of the investigation to predictions made prior to the investigation.

Science (NEW), Grade 3, STRAND 6: EARTH AND SPACE SCIENCE
Standard 21: Identify, describe, and analyze properties of the Earth and its atmosphere. 21.3. Classify rocks based on their physical properties:

**Enduring Understandings**
1. All life on earth depends on earth materials. Earth materials, with the addition of the sun's energy, provide the food, air, and water that every plant and animal needs to survive.

2. The act of taking apart a material and then putting it back together gives one a better understanding of the material.

3. It is important to use the earth's materials wisely.

**Essential Questions**
How can the knowledge of what makes up the earth enhance our lives?

How does taking apart a material help you to determine the origin and history of that material?

Why is it important to use the earth's materials wisely?
