BioSleuths @ Belle Valley – Friday: Forensic Entomology

BioSleuths @ Belle Valley – Friday: Forensic Entomology

Today, students continued their study of forensic entomology: the use of knowledge of insects to help solve criminal investigations. Our junior investigators learned how forensic entomologists use the life cycle of maggot-laying flies in order to determine the exact time of death of a victim. In order to observe the life cycle in action, students examined their canned chicken samples from Monday.

In addition, the biosleuths used the knowledge they had gained about forensic entomology to solve crime scene situations!

Ask your student:

What exactly are maggots? (fly larva)

How can forensic scientists use maggots to estimate time of death? (life stages of a fly take a known amount of time)

CSIMSA @ Belle Valley – Friday: Drops to DNA Part 2

CSIMSA @ Belle Valley – 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?

Vital Signs @ Chicago – Monday: Glasses Galore

Vital Signs @ Chicago – Monday: Glasses Galore

On the first day of a jam-packed week, students delved into bio engineering, specifically creating glasses! Our budding engineers explored the different types of lenses and their ability to magnify and minimize objects from various distances. The campers combined different strengths of lenses to enhance their vision and read ultra-fine print from 6 and 8 feet away.

Ask your student:

Do eyeballs have convex or concave lenses? (convex)

CSImsa @ Chicago – Monday: Observation 101

CSImsa @ Chicago – 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?
