Columbus discovered America?  But he only made landfall in the Bahamas and Cuba?  Wait didn’t the Vikings make the voyage before he did?  Wait the Chinese mapped out the America’s 70 years before the Viking voyage?  Wait, didn’t native american Indian’s “discover” the America’s first?  Wait wasn’t the America’s already here?

______________________________________________                                                                                            10/10 – Tuesday “A” Day –

Main focus:

1. To observe the phase changes in a Cooling and Heating Curve of water.
2. To identify the Phase changes and the melting and boiling point from a heating curve.
3. To identify the identity of an unknown substance by its melting/Freezing point.

Period  7:

1.  Lab 4 – Cooling Curve of an unknown substance.

We will gather data for the Cooling Curve Lab 4.

LAB 4 -Cooling curve of an unknown substance .pdf

– MELTED OUR SAMPLES
– Cooled them and graphed the temperature  every 30 seconds for 60 minutes.
– Identified the experimental freezing point graphically and from data points staying the most constant
– Identified our sample based on the freezing point.
– Calculated the percent error.
