It is expected that anyone who was present in class will have the rough draft of Part One in the ISN and ready for peer review.
The project is
Practical
Assessment: Physical Properties and SC.8.N.1 (Scientific Methods and Data
Analysis)
It is now 15 years in the future and you have been hired as
a consultant by NASA. Your job is to design an experiment or series of
experiments to be conducted in a glove box. You must write the complete
directions for the procedure using only the materials that NASA will supply.
The problem to be investigated is the sample of materials
that were retrieved from an unknown asteroid. NASA wants to test the individual
components of the sample, but first the sample has to be deconstructed or
broken down into its key components. NASA has limited you to only using the
physical properties of the material to deconstruct it. You must not only
develop a hypothesis or hypotheses, and procedures; but you must run the
experiment to gather data and write a conclusion. You will be given an analog
to use for the experiment that NASA is certain is very similar to the unknown
sample. There are indications from previous studies that the sample contains at
least 3 substances. REMEMBER, the NASA techs will replicate your directions in
a GLOVE BOX so they will not be able to do any very fine motor tasks.
Materials provided by NASA include a plastic cup, oil,
water, filter paper or coffee filter, foam plate and a transfer pipette. You
may request access to other lab equipment.
You will need to complete a formal proposal of procedures
before you get your materials (Foldable). Start with your rough draft in your
ISN.
·
Problem: Use the principals of physical
properties to deconstruct a sample for further study.
·
Question: How can physical properties be used to
separate the individual components of a sample?
·
Variables: Identify the tested (manipulated or
independent) variable; the outcome (responding or dependent) variable, and the
variables held constant.
·
Hypothesis or hypotheses (you may need more than
one if you have subsets of your experiment); use the variables to develop the
hypotheses..
·
Materials
·
Procedures (Be very systematic)
After completing your procedures and hypotheses and
receiving approval you will be given the materials to run the experiment. Keep
your notes in your ISN and include the following for the final report.
