5. Analyze the data.
6. Finally conclude and create a conclusion.
Lab 1.1- Baking Soda Lab
-Baking soda releases gas when heated.
-Tea is the indicator.
-Control group is the unheated baking soda and tea.
-Experimental group is the heated baking soda and tea.
-When heating soda is heated, it is no longer baking soda.
-Condensation is created when b. soda is heated.
-If the color is different, the the heated b. soda must've been changed.
a. amount of baking soda.
b. amount of tea.
c. same type of tea.
d. amount of stirring time.
a. Hole in the tubing.
b. Rubber stopper is loose.
c. Tubing isn't in the top of the bottle.
d. Cap burner before removing tube.
-Cubic Centimeters equals Millilitters.
Equation- L x H x W.
1 centimeter equals .01 meter.
100 Centimeters equals 1 meter.
1 mL = 1cm3.
Lab 1.4- Displacement of Water Lab
-Dry Sand - Sand Alone = Air Space
-Experimental Error- Funnel in wrong place.
-is over of = air over dry sand.
Lab 1.8- Paper Square Stuff
-Delta Mass = Change in mass.
-Sensitivity of Balance= Delta Mass divided by # of yes'.
Lab 2.1- Dissolving Salt!
Lab 2.4- Ice Ice Baby
Conservation of Mass Notes
Property of substance: identifies what the object is made up of.
Mass and Volume Notes
-The mass of an object will double if its volume doubles.
-Objects that have the same volume but are made of different substances will not have the same mass.
Al= Aluminum = 2.7g/cm3
Measuring Volume of a Cube
*For accuracy all Lab Partners should check measurements.
Lab 3.5- Metal Object Densities
Mass Increase = Density Increase
Volume Decrease = Density Increase
Mass Decrease = Density Decrease
Volume Increase = Density Decrease
Lab 3.6- Comparing Liquids with Densities
Section 3.8- These Shenanigans
Gold : 19.3 = M divided by 100, Cross Multiply = 1,930.
1.2 x 10^-3 g/cm3= M divided by V, 11m x 17m x 3m. 1100cm, 1700cm, 300cm =5.6 x 108cm3 Final= 6.7x105
