Tonight, you should do all of the following (and see the note all the way at the bottom of this entry):
1. Complete the Pie-Chart Template; (I've reproduced the form and data table below if you forgot to bring yours home). Period 2 and 4 should also go through and prepare a pie chart or bar graph based on Table 2);
2. Color in the Pie-Chart Template;
3. Answer Analysis Questions on p. B-53; and
4. Finish copying vocab from class, shown below:
Activity 22 - Analysis Questions
1.
What are the top three materials by weight in a
computer?
2.
You are a materials scientist asked to present
the information in tables 1 and 2 to a group of computer manufacturers who want
to reduce the environmental damage caused by old computers. What information
from these tables would help them? List at least three statements from the data
tables shown here, including a summary of your pie chart.
3.
Based on your list from Analysis Question 2,
what two statements do you think are the most important to discuss with the
manufacturers? Explain why they are the
most important.
Vocab (define in vocab section with dated cross reference in science notes):
- composition -make-up
- Metal- category of elements with shiny surface, good conductivity, and flexibility (can be melted, fused, hammered into sheets or drawn into wires).
- Non-Metal - category of elements with dull surfaces (no luster), brittle (easily breakable), poor conductivity of heat & electricity.
- Percent composition - how many parts per hundred made up a material. Ex: One percent (1%) means one part per hundred; therefore, seawater is 3.5 parts per hundred in solution.
- Reactants - chemicals put in to a reaction (starting substances).
- Products - chemicals that are put out from a reaction (substances at the end of a reaction).
- Polymer - are made of repeating molecules (monomers) linked together ("many parts"). Ex: plastics
