Village of Barboursville Elementary 4th grade TAG
January 4, 2005
Use the Simple machine sets to build the chair.
The range of building times was 3 and half minutes to 17 minutes.
That data was used to make a bar graph.
Find the measurement of the chair at its most upright position
WITHOUT measuring that position.
Use a protractor to measure the angle the chair back makes with the
seat
when placed in the first six positions.
Record the data and draw a line graph.
Then using that information estimate the actual reading for the that
7th position.
They did their graphs by hand and then colored them.
