Warm up 11/5/14

In your journal write an example of a chemical change you observed in class yesterday and talk about the indicators you saw that prove it was a chemical change.

Warm up 11/6/141. Look at the picture of baking soda and vinegar, what evidence

of a chemical change do you see?

2. In the picture below you can see evidence of a temperature change, production of light, and a gas. All these indicators prove that what kind of change is happening?

• Claim- The cube has a density of 7.9 g/cm3 and is made of Steel.

• Evidence- The mass of the cube is 79g. The volume of the cube is 10 cm3. When you divide the mass by the volume you get a density of 7.9g/cm3. The table shows that the density of steel is 7.9 g/cm3.

• Reasoning- No other substances have the same density, and the unknown cube matches the density of steel. Density is unique to every substance.

• Remove and hole punch workbook pages into your science binder.

• Look for pages 116-120, 126-132, 336-348, 138-149.

• WHILE YOU ARE WAITING Today You will work on pages 138-149.
