Quarter 1 Class Notes

Tuesday October 17th

Graphing our data from 7.1.

How do we create a line graph from our change of temperature over time data from experiment 7.1.

Important understandings

1) Independent Variables and Dependent Variables

2) How to label and scale your axis (x and y)

3) Title of your graph

4) Plotting your data on the graph

5) Interpreting what your data means

Thursday Oct. 12th and Monday Oct.16th

7.1 Phases of matter lab.

-What are the phases of matter and what are the transitions between them.

Solid - fixed volume and shape (can be bent or malformed)

Liquid - fixed volume, no fixed shape

Gas - No fixed shape or volume

Phase diagrams and understandings of melting, freezing, boiling(vaporization), evaporation, and condensation.

Temperature = average energy of molecular motion in a substance

Heat = total energy of molecular motion in a substance

Wednesday October 11th

How convection currents are controlled by density

Types of currents

Gas (Atmosphere, rooms, caused by warm air)
Liquid (Oceans and Lakes)
Liquid solids (Mantle and plate tectonics)

Reading and notes -textbook pg. 48 - 51 convection currents.

Plan for Density of Air lab and Conduct the Lab

-Need 4.1 Density Lab worksheet

Monday October 2nd -

Important understandings in science

1) Measuring Volume

a) l x w x h (calculating volume using measurements)

b) Displacement (calculating volume by the amount of liquid moved)

2) Calculating Density

Mass/Volume = Density

3) Vocabulary

Matter, Mass, Weight, Volume, Density, Displacement

4) Skills

Friday September 29th -

Today we finished 3.1 and reviewed the answers.

-General understandings that objects float and sink depending on their density. Also, how high they float depends on how close their densities are together.

*See the photo of the board for more information.

Thursday September 28th -

IN Calculating the density of Regular objects

Wednesday September 27th -

IN Calculating the area of a regular object.

Tuesday September 26th -

Density Test Day

Monday September 25th -

Activity - Bar Graph practice with handouts. (See attached)

Notes - Test prep for tomorrow.

1) Know the definitions of Matter, Mass, Volume, and Density

2) Be prepared to measure volume, mass, and calculate density on a variety of objects.

Friday September 22nd -

Activity - Lab 2.3 Calculating Density of Irregular objects.

How to write a conclusion - "My hypothesis is correct/incorrect because according to my data ....."

Thursday September 21st-

Density is the amount of mass in a unit of volume.

Density = Mass / Volume

Water has a density of 1 g/cm3

If an objects density of less than 1, it will float on water. If an objects density is more than 1 it will sink.

Wednesday September 20 -
