Properties of Materials – Part A

Unit Objectives: By the end of this unit (Part A), you should be able to:

1. Describe how objects in the universe range from smaller than atoms to larger than galaxies,
2. Explain how the metric system works and compare it to the English system of measurement,
3. Properly use metric prefixes [micro- (µ), centi- (c), deci- (d), kilo- (k), mega- (M), giga- (G)],
4. Convert from smaller to larger units within the metric system and between the metric & English systems,
5. Use scientific notation to simplify calculations,
6. Use a calculator to figure basic functions, roots, and scientific notation,
7. Measure distance, mass, volume and temperature with precision and accuracy,
8. Recognize that there is uncertainty in all measurements,

176-200 pts 150-175 pts 124-149 pts 98-123 pts < 98 pts

C Layer:     You must earn at least 124 points, but may not exceed 149 points.

> Required of everyone are the options marked R (Required)

>  You must do at least 1 options from the Basic Knowledge section

>  You must do at least 1 of the Basic Math options

>  You must do at least 1 options from the Accuracy & Precision section

* Choose extra assignments in order to earn the rest of your points from this layer.  Try to earn the maximum # of points!

• B Layer:    Choose one assignment, worth up to 25 points.  Be sure you will have earned at least 124 points in the C Layer.
 Description Worth (pts) Pts Earned Initial Complete the Density of Various Materials activity.  Write a lab report that follows B Layer Lab Guidelines. 25 How accurate and precise is your car’s speedometer?  Design and conduct an experiment to test this in both the English system of measurement and the Metric system. 25 Imagine that you have been invited to teach a lesson to your 4th grade teacher’s class.  Design an original measurement activity for his/her current students.  The activity you design should be long enough to last 50 minutes.  Include enough hands-on experiences to effectively teach your students about all measurements that we discussed in this unit.  (Refer to the appropriate product card for guidelines on this.) 25

• A Layer: Choose one!  Worth up to 25 points.  Be sure that you will have earned at least 150 points in the C & B Layers!
 Assignment Description Worth (pts) Pts Earned Initial Could science exist without math?  Could math exist without science?  Explain. 25 Read the following article -  http://mars.jpl.nasa.gov/msp98/news/mco991110.html   Do you think the global scientific community should use one common measurement system?  Explain. 25 What type of work does a materials engineer do?  (<250 words) 25
2. Find 3 sources of info and complete an A Layer Assignment Sheet.
3. Present your information in an essay (350+ words), a PowerPoint Presentation (6+ slides), or an oral presentation (3 min.)
