6th grade ProjectDensity Column

PROBLEM:

  1. Students are being asked to apply the Scientific Method Thought Process to create aliquid density column with a minimum of three liquids. Students are also being asked to follow the lab report format for submitting their solutions.
  2. The density column must include a lid.
  3. The density column must have your full name, date and period on it written legibly with permanent marker.
  4. NO flammable substances or drinking alcohol may be used.
  5. PROJECTS will REST for at least THREE DAYS before scoring. Liquids must maintain their layering this entire time.

BACKGROUND/RESEARCH:(sites and/or notes completed prior to beginning project)

Density columns are an extended version of oil and water where multiple colored liquids are layered for an aesthetically-pleasing effect. The column is made of layers of liquids of different densities. The highest density liquid is on the bottom of the column. Going up the column, the density of each successive layer decreases, with the least dense layer on top.

Some resources:

A report with the following documentation is required ona separate paper. This page should help you organize your report.

HYPOTHESIS:

If ______

then ______

because ______

MATERIALS: (list of all materials used to complete project in metric units)

PROCEDURE: (numbered step by step process used to complete the project)

OBSERVATIONS:

*graphic that identifies what each liquid is and what layer it is in

- identifies the liquid

- identifies color of the liquid

- identifies the layer each liquid is placed in

- labeled from top to bottom.

INFERENCE/CONCLUSION: Statement evaluating the student’s hypothesis, learning outcomes, or strengths and weakness reached by students in completing their objectives.

Was your hypothesis correct? Why or why not?

Did your layers stay separated? Why or why not?

NEW TESTABLE QUESTION:

(What is one way you would change this project so you could further test density?)

GLOBAL CONTEXTS and/or LEARNER PROFILES: Explanation of at least 2 Global Contexts and or Learner Profiles which were applicable in completion of this project.

Scoring:

1 - 2 = 2 or fewer layers or a non-approved liquid was used; may have insufficient documentation

3 - 4 = 3 tor4 visible layers or a non-approved liquid was used; may have insufficient documentation

5 - 6 = 5 or more visible layers; correct documentation

7 - 8 = 5 or more visible layers with a solid object suspended between layer; correct documentation

7 – 8 5 – 6 3 – 4 1 – 2 0
