=__Model 1-1 Science Lesson Experiment (Identity of the Unknown Objects)__=

-Team Members:
melissa dawn adam

-Materials:
electronic balance metric ruler graduated cylinder 10 sample items beaker of water calculator computer

-Methods:
1. Make qualitative analysis of each object and record 2. Hypothesize the identiy of each object, using qualitative analysis 3. Design exel table to record qualitiative data 4. Find mass of each object and record 5. Using water displacement, find volume of irregualr object and record 6. Using metric ruler, find volume of regular shaped objects (V = l x w x h) and record 7. Find the density of each object using the formula: D = m/V 8. Use internet resources to correctly id the objects based on the found densities. 9. Reflect upon hypothesis to determine the correct id.

-Hypotheses:
(Develop hypotheses about the ID of the objects based upon initial observation and through debate and process of elimination among your group members. Create a table with the object #, hypothesis as to ID, and reason for hypothesis. Use MS Excel and make sure include a table number and title underneath it.)



-Quantitative Data:
(What quantitative data are relevant to determining the identity of the objects? What is quantitative data? Think in terms of density. Make all measurements in metric units and round to the tenths place at the final step of calculation. Your final product in this section will be a MS Excel table with the Cube #, mass (g), Volume (cc), density ( g/cc ) Make sure include a table number and title underneath it.
 * Table 2- Quantitative Data- Group 1 ||
 * Cube # || Mass(g) || Volume(cc) || Density(g/cc) ||
 * 1 || 138.1 || 15.63 || 8.84 ||
 * 2 || 44.2 || 15.63 || 2.83 ||
 * 3 || 7.9 || 3.0 || 2.63 ||
 * 4 || 22.5 || 15.63 || 1.44 ||
 * 5 || 130 || 15.63 || 8.32 ||
 * 6 || 5.3 || 15.6 || 0.34 ||
 * 7 || 19 || 15.63 || 1.22 ||

 * 9 || 11.1 || 15.63 || 0.71 ||
 * 10 || 17.8 || 15.63 || 1.14 ||

-Qualitative Data:
(What qualitative data are relevant to determining the identity of the objects? What is qualitative data? Brainstorm and create a list of qualitative data categories that could be used for the objects. Create a table in MS Excel with the Cube # and all qualitative data. Make sure include a table number and title underneath it.)
 * Table 3- Qualitative Data on 10 Objects ||  ||
 * Object # || Color || Texture || "Heaviness" || Type of Material ||
 * 1 || brassy || rough || heavy || metallic ||
 * 2 || silver || smooth || light || metallic ||
 * 3 || opaque || rough || medium || crystal ||
 * 4 || gray || smooth || light || nonmetallic ||
 * 5 || tarnished silver || smooth || heavy || metallic ||
 * 6 || beige || smooth || light || nonmetallic(wood) ||
 * 7 || white || smooth || medium || nonmetallic(plastic) ||
 * 8 || light brown || smooth || light || nonmetallic(wood) ||
 * 9 || brown || smooth || light || nonmetallic(wood) ||
 * 10 || clear || smooth || light || nonmetallic(plastic) ||

-Research on Cube Possibilities (Citations Also, MLA):
 [Create a table in Excel with a proper table number and title that contains each of the names of the possible object identities (see the list on the "model project page" ). In addition, this table should contain a column for density found on the internet, qualitative properties found on the internet, and the MLA Citations that correspond to the information.]

-Final Identifications:
 (Develop your final ID's of the objects based upon your research of the densities, the calculated densities, and the qualitative research/ collected qualitative data. Create a table with the object #, final guess re: ID, and your REASONING.)
 * Table 5-Final Identification of 10 Objects- Group 1 ||
 * Cube # || Final ID || Reasoning ||
 * 1 || Brass || Density ||
 * 2 || Aluminum || Density ||
 * 3 || Quartz || Prior Knowledge ||
 * 4 || Nylon || Density/Color ||
 * 5 || Iron || Density ||
 * 6 || Pine || Smell/Color ||
 * 7 || PVC || Color ||
 * 8 || Poplar || Grain/Density ||
 * 9 || Oak || Grain/Color ||
 * 10 || Acrylic || Prior Knowledge ||

-(Optional) Graph of Objects:
 [Create a graph using Excel with the calculated densities of the objects on the Y axis (dependent variable) and the object numbers on the X axis (independent variable). Draw a thick horizontal black line across the 1 g/cc mark on the graph. Write a paragraph in third person scientific writing about what you can deduce about buoyancy based upon this graph. Make sure your graph has a graph number and title.]
