Students were responsible for

• Reading the story of Lyle and Louise
• Writing a one page report summarizing the story
  of Lyle and Louise and writing a scenario what
  they thought happened based on the evidence
• Creating a detective notebook listing the
  victims, suspects, crime scene, evidence found,
  findings from the blood spatter analysis
  stringing technique, math concepts used, and who
  they think killed Lyle and Louise
• Dropping blood onto the angle boxes and
  calculating the length, width, and mean
• Using trig functions to calculate the angles of
  the blood dropped so they could string their
  boxes
• Explain the importance of the stringing technique
  
• work in a group to present their findings to the
  class and write a one page report on those
  findings

Measuring blood drops

So how many days did we spend on the project?

• Day 1 Students read the story and wrote a
  summary of the events and what they thought
  happened. Students made their detective
  notebooks.
• Day 2 We presented Dr. Murrays slides on
  blood spatter and had a discussion. (She has
  since posted a power point.) Our block class
  made furniture out of clay for the crime scene.
• Day 3 We gave the students blood spatter D
  handout to measure the blood spatter so they
  could find the width, length, and averages. Our
  block class painted and designed their crime
  scene boxes.
• Day 4 Students dropped blood onto the angle
  boxes. (We suggest allowing two days for this
  part if it is a 50 minute class.)
• Day 5 We taught the trig lesson and gave them
  a trig worksheet to complete together.
• Day 6 Students were given blood spatter walls
  A, B, and C and found the width, length, and
  angle of each of the fifteen drops they circle.
  We gave them a pre-made worksheet to record the
  data on.
• Day 7 Students attached A, B, and C blood
  spatter papers to the cabin walls. We also
  demonstrated how to string the boxes so they
  could start stringing.
• Day 8 Students finished stringing their boxes
  and each group had to write a summary of the
  story and what the whole group thought happened
  based on the convergence of the string.
• Day 9 Students gave group presentations.
