Students read and respond to questions about the life and mathematical work of Lewis Howard Latimer. A mathematical formula is used to calculate the intensity of light given the distance from a given light source. Students are asked to describe the pattern they see and also graph the values.

DUTIES:

  1. Reader will read biography to the group
  2. Scribe will complete the worksheet and history connection questions.
  3. Listener will compute the figures for worksheet
  4. Materials Manager will distribute materials to the group and collect them at the end of the activity.

MATERIALS:

  1. Latimer Biography
  2. Latimer Worksheet
  3. Calculator
  4. Graph Paper
  5. Ruler
  6. Paper
  7. Pencil

DIRECTIONS:

  1. Complete the reading on the Biography of Lewis Latimer.
  2. Complete questions on History Connection.
  3. Complete Latimer Worksheet.
  4. Complete graph using the graph paper labeling distance on the x-axis and intensity on the y-axis.

    HINT: The x-axis should be labeled in increments of 1 and the y-axis should be labeled in increments of 500.

PRODUCT:

  1. Worksheet
  2. Graph

CLEAN-UP:

    All materials listed should be neatly placed in the basket
