CSImsa @ Chicago – Wednesday: Tie Dyes

CSImsa @ Chicago – 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?

Vital Signs @ Chicago – Wednesday: A (Simulated) Urinalysis

Vital Signs @ Chicago – Wednesday: A (Simulated) Urinalysis

Today, our junior medical practitioners were put to work in the lab! Our campers learned that many different diseases can be diagnosed based on the pH of urine.  Using (simulated) urine, they tested the pH levels of various samples and then handed out diagnoses based on the results. Our fledgling scientists will continue to use their rapidly developing medical skills in the days to come!

Ask your camper: What diseases are possible if a urine sample is a pH of 3.0?

 

Vital Signs @ Chicago – Tuesday: Sheep Heart Dissection

Vital Signs @ Chicago – Tuesday: Sheep Heart Dissection

Day 2 is over, and our daring dissectors have had an in-depth look at the workings of every mammal’s most important organ: the heart! During their exploration, students continued to recognize the relationship between structure and function that is present everywhere in biological structures. One student commented, “Every piece of the organ has a specific job, and everything is efficient!”

The scientists-in-training will continue to explore this connection between structure and function as the week goes on!

CSImsa @ Chicago – Tuesday: Lift a Finger

CSImsa @ Chicago – 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?
