Purpose:
To practice using several different scientific “devices” to become proficient
(Successful) in using the SI (International System of Measurement). As well, the
you will become familiar with data tables and graphing (using different graphing
methods) to illustrate the results of the SI measurements.
Materials:
metric cm/mm ruler, scale, magnifying glass, 10 loops
Procedure:
1.
Weigh 10 loops (together) on the scale (in grams). Divide your number
by 10 (to get the average). Do this by simply moving the decimal point to the left one
position. (i.e. 43 grams/10 loops = 4.3g each) RECORD: in space provided
2.
View a loop with the magnifying glass. DRAW: the loop in the space provided as
detailed as you can.
3.
Using a metric ruler, measure each loop, RECORD: the measurements in mm on the
provided data table, keep the loops in their respective color categories. When done
measuring and recording, place DATA on CLASS TABLE on board in front of room.
4.
Using the DATA table measurements, GRAPH: using a BAR graph, a SCATTER
graph and a PIE graph.
5.
The scatter graph will have all of the widths of each color placed in their column and
the width on the left, place a single heavy dot to represent loop (may have some
near)
The pie graph will indicate the percentage of each color represented, take the
amount of each color and divide by total loops (10) so, ie. 13/10 = 65% put in wedge
remember, if you add all percentages they should equal 100%
The bar graph will simply indicate how many of each color there are, shade in the
number of squares to indicate how many of each color
