Measurement and Problem Solving: textbook readings

Classification of Matter
Physical & Chemical Properties
Physical & Chemical Changes

This section in the textbook talks about the how to determine if a sample is a mixture, solution, compound, or element. It also talks about what are physical properties and chemical properties, plus how to recognize a physical change versus a chemical change.

In the picture, the man is using a sluice to separate gold from a mixture of sand and water. That involves knowing the physical properties of sand and gold and doing physical changes to extract the gold.

	Uncertainty in Measurement & precision/accuracy This section in the textbook talks about the difference between measurements that have good precision versus those that have good accuracy or those that have neither or both.

	The textbook has a certain way of doing conversions and solving math problems, but I don't use their methods. You will find my method of doing it reinforced in the tutorials and in the problems I give in Sapling Learning. I think my method is more powerful and more logical. Just like any approach, it takes some time to get acquainted with the technique.
