The new challenge for B day and A day

The new challenge was introduced to B-day on Tuesday, 2/23, and to A-day on Wednesday, 2/24.

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.

·        Data

·        Results

·        Conclusion
