C.S.IMSA – Friday: Drops to DNA Part 2

C.S.IMSA  – Friday: Drops to DNA Part 2

The case has been cracked! Our junior forensic scientists worked in the lab today in order to extract DNA from the pieces of a broken vase that were found at the crime scene. After analyzing the evidence and comparing it to the DNA samples from several key suspects, the CSI team has identified the culprit!

Students concluded the week with a successfully cracked case, and experience with real CSI science!

Ask your student:

Were your suspicions from earlier in the week correct? If not, what evidence changed them?

C.S.IMSA @ Springfield – Thursday: Drops to DNA Part 1

C.S.IMSA @ Springfield – Thursday: Drops to DNA Part 1

Today our CSI technicians began what will be a two day process to extract DNA from a broken vase found at the crime scene. In order to prepare themselves to discover what should be the most convincing piece of evidence, students learned about the extraction process by using their own DNA!

After their training, investigators are ready to process the last piece of evidence tomorrow!

Ask your student:

What was one substance you used in the extraction of your own DNA? (Gatorade, soap, meat tenderizer, alcohol)

C.S.IMSA @ Sprinfield – Wednesday: Tie Dyes

C.S.IMSA @ Sprinfield – Wednesday: Tie Dyes

The crime scene team began analyzing a promising new lead today by testing oil samples found on the driveway at the crime scene and comparing them with oil samples from suspects’ driveways. Students discovered the uses for the science of chromatography by watching how different colors separate, and using that information to match the crime scene oil with a likely culprit.

Our forensic scientists are developing a clearer picture of the case, and feel close to a breakthrough!

Ask your student:

What is chromatography used for? (separating materials)

What new information did you learn from your evidence analysis today?

C.S.IMSA @ Springfield – Tuesday: Lift a Finger

C.S.IMSA @ Springfield – Tuesday: Lift a Finger

Our CSI team is well on its way to cracking the case! Today, the scientists-in-training delved into the study of fingerprints. They first fingerprinted themselves in order to learn about the different recognizable fingerprint patterns. Students then examined the fingerprint evidence collected from the crime scene and attempted to match it with prints collected later from suspects.

Our investigators have had a busy two days, but there is more forensic science to be done before the culprit can be apprehended!

Ask your student:

What are the three characteristic fingerprint patterns? (loops, whorls, and arches)

After two days, do you have any theories about the case?

CSImsa @ Springfield – Monday: Observation 101

CSImsa @ Springfield – Monday: Observation 101

The detectives have called in the CSI unit, and our junior forensic scientists are on the case! The investigation is well under way, with students honing their observation skills by spotting hidden objects in various pictures. They also practiced their mastery of memory and recall by seeing a series of objects and attempting to remember what was shown.

Investigators will continue to utilize their observational talent throughout the week as they attempt to solve the case!

Ask your student:

What evidence have you collected so far in the case?

How did you do in your observation and memory skills practice?

A crushed can was found at the scene of the crime, surrounded by the shards of a broken vase. What was in the vase? Why was it so important to the perpetrator?

Our C.S.IMSA Investigators are designing an experiment to replicate the evidence to determine the approximate weight and height of the broken vase. Listen to their great explanation!
