Lab: Reaction in a Bag

  • Combine solid A and solid B with a red liquid in a paper bag to make a reaction.
  • Reaction - Warm and cold, yellow, bubbly, bag inflates, solids dissolve, and a gas filled up the bag.

Chapter 1

1.1 Lab: Baking Soda

  • When baking soda is heated it turns into a different substance.
  • Heated baking soda in tea is a different color than non-heated baking soda in tea.
  • Condensation formed near the top of the test tube.

1.2 Notes: Volume

  • L x W x H
  • Standard unit of length = Meter (m)
  • 100 centimeters = 1 m
  • Use a graduated cylinder to measure volume
  • 1 mL = 1 cm^3

1.4 Lab: Measuring Volume by Displacement of Water

  • (Sand + Water) - Water = Sand alone
  • (Dry sand + Air) - Sand alone = Volume of air
  • % of sand that is air = is/of = air/dry sand

1.8 Lab: The Sensitivity of a Balance

  • 0.02 is the sensitivity of our balances.

Chapter 2

2.1 Lab: The Mass of Dissolved Salt

  • When adding salt into water, the mass decreases.

2.4 Lab: The Mass of Ice and Water

  • Condensation easily forms

2.5 Lab: The Mass of Copper and Sulfur

  • Condensation, white-yellow gas, bubbles, black liquid that turned clear, and a new black solid after the reaction.

2.6 Lab: Mass of a Gas

  • There should be no change in mass.

Chapter 3

3.2 Lab: Mass and Volume

  • Objects made of the same substance and have the same volume, will have the same mass.
  • Objects made of different substances, but have the same volume, will not have the same mass.

3.5 Lab: The Density of Solids

3.6 Lab: The Density of Liquids

3.7 Lab: The Density of a Gas
