An Atomic Assault
A father is accused of assault with a radioactive substance. To go forward with a criminal case, investigators need to know what substance was used. Students will study radiation, radioactive decay, and half-life to determine what radioactive substance was used.
The student understands the basic processes of nuclear chemistry. The student is expected to:
(A) describe the characteristics of alpha, beta, and gamma radiation;
(B) describe radioactive decay process in terms of balanced nuclear equations; and
(C) explain half-life
- Introduction and Case File: A summary of the case
- Case Notes and Analysis: A place for students to record observations about the case, summarize learning, and to apply new information to the case.
- Case Research Part I: Students read case studies and explanatory text about alpha decay.
- Case Research Part II: Students read case studies and explanatory text about beta decay.
- Case Research Part III: Students read case studies and explanatory text about gamma radiation.
- Case Research Part IV: Students read case studies and explanatory text about half-life.
- Case Summary: Students summarize their conclusions.
- Practice Worksheet: Student worksheet to review writing nuclear equations and types of radiation.
- Teacher Notes: Additional notes for teachers and answer keys.
