Understanding the Bombs Used at the Boston Marathon <- your first lab link 1. Explain the work being done at the New Mexico Institute of Mining and Technology and why it is significant.

2. Following a bombing, what does Romero explain needs to be collected and why?

3. What type of forensic evidence was recovered during the bomb set off at the New Mexico facility on the video that was similar to the evidence obtained at the Boston bombings and how did this evidence allow researchers to connect other pieces of evidence to the same bomb?

4. Given that pressure cooker bombs can be created using information readily available online, why does Romero believe the Boston bombers had some level of experience in creating bombs?

5. Explain why scientists record explosions at the New Mexico facility?

Bombing of America <- your second lab link
Use the After the Blast, Juvenile Bombers, and Prime Suspect links in the middle of the page to learn more about how forensic scientists investigate crimes involving bombs and other explosives.

Hot Science: Chemical Residue <- your third lab link
Use this link to learn more about how chemical residues are tested during an investigation.

1. What types of evidence might be found at a bomb scene that could help investigators catch the bomber? Choose one of the types of evidence that you've identified and discuss how forensic scientists might find this type of evidence at the scene and what information it might give them.

2. What is chromatography? Describe the process of chromatography and what forensic scientists can learn from it.

3. Why do some teens and children create bombs? What are the risks of doing so?

4. What types of evidence did forensic scientists have in the Unabomber case? Choose one type of evidence and why this type of evidence would be important in linking an individual to a crime.
