Vital Signs @ Springfield – Friday: Animatronic Extremity

Vital Signs @ Springfield – Friday: Animatronic Extremity

Throughout the week, students have been exploring the realm of artificial prosthetics through the use of their own engineering creativity. Our bold inventors have created their own artificial hands, improving them day by day, and testing them with games and activities. Experiments involved carrying ping-pong balls, and even sign language!

Students have become experts at analyzing design solutions and repeatedly testing them in order to determine the best way to improve the product.

Ask your student:

What is electromyography, and how do modern prosthetics take advantage of it? (voluntary signals that contract muscles, prosthetics can be controlled using remaining nerve endings)

Ask them to show some of the sign language they learned this week!

BioSleuths @ Springfield – Friday: Forensic Entomology

BioSleuths @ Springfield – 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)

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?
