Course: Physical Science Grade Level(s): 8th
Content: Unit II Properties of Matter & Energy // Measuring Volume, Measuring Density Week: 8
 California Academic Content Standards emphasized: 8. All objects experience a buoyant force when immersed in a fluid. As a basis for understanding this concept, students know:
a. density is mass per unit volume.
b. how to calculate the density of substances (regular and irregular solids, and liquids) from measurements of mass and volume.

 9. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept, and to address the content the other three strands, students should develop their own questions and perform investigations. Students will:
a. plan and conduct a scientific investigation to test a hypothesis.
b. evaluate the accuracy and reproducibility of data.
e. construct appropriate graphs from data and develop quantitative statements about the relationships between variables.
f. apply simple mathematical relationships to determine one quantity given the other two (including speed = distance/time, density = mass/volume, force = pressure x area, volume=area x height).

Key Ideas: volume, area, how to use a triple beam balance, graduated cylinder, measuring mass, using a three variable equation in the form of Density=mass /volume, find the density of solids, liquids, and gases, designing an experiment, scientific report writing, scientific illustration.
 

 CLASS MEETING AGENDA/ ACTIVITY

 MEETING 1

 [1] Collect "Physical Science SkillWork", CBS-2 [3] Wrap up the "Conservation of Mass" exploration. [3] Start the " How much space do I take up?" scientific Investigation of measuring space, if time allows

MEETING 2

 [1] Collect PS POW-2: "Bobo and the Baffled Magician"[2] Wrap up the " How much space do I take up?" scientific Investigation if needed. Start the "What's my match? scientifici investigation into using physical properties to sort matter.
 

HOME SESSION AGENDA/ ACTIVITY

SESSION 1

 [1] Work on finding a solution to PS POW-2: "Bobo and the Baffled Magician" which will be due at the second class meeting of the 8th week. [2] Work on the "Physical Science SkillWork", CBS-2, (only if CBS-1 was not mastered) be hand it in during the first class meeting of week 8. [3] Read pages 826-827 in F on PS.

SESSION 2

 Complete the observation and the data collection worksheets and the graph. After you have finished, in your ISSN, on the left (output) side, make a "Here I Stand" entry to summarize what you learned during the "Conservation of Mass" investigation.

SESSION 3

 Work of your "Going Further" assignment from this week's 2nd meeting investigation - What's my match?
