Properties of Matter & Mixtures Lab1. Problem/ Purpose statement

Can a mixture of sugar, sawdust, iron, and sand be physically separated?a. Background Information:

(leave 3-4 spaces)2. Hypothesis

If we consider the properties of matter, we will be able to separate a mixture of sugar, sawdust, iron and sand.

3. Variables: N/A4. Constant: sugar, iron, sawdust, and sand5. Control: N/A6. Record Data

7. Conclusion1) Summarize: How did you separate the materials in the beaker?2) Why is it important for scientists to write detailed procedures? 3) Why didn’t you measure the melting points of sand, wood, or iron in this lab? 4) Did you have to completely alter /chemically change any of the materials to measure their physical properties? Explain. 5) Scientists often find mysterious materials. Explain how physical properties are important for identifying unknown substances.
