Time of death

Time of death 1.2.2

Lesson Plan: The next step in examining the death of Anna Garcia is to determine her time of death. Time of death can be estimated in a variety of ways. Early signs that can be evaluated are the clouding of the corneas and the core body temperature. Later signs include the pooling of blood in the skin, rigor mortis, and insect eggs and larva in orifices and skin/muscle.

In this activity, you will learn about different types of evidence that are used to determine time of death, and experimentally determine the effects of ambient temperature on the cooling of the body after death.

Lesson Goals

1. Evaluate evidence to determine time of death.
2. Analyze the results of a scientific experiment.
