Handwriting Analysis and Chromatography

By Brienne

This week in S4S Calumet, we learned about handwriting analysis and chromatography from a real life forensic scientist!! Angela Cloud-Simmons is a substance forensic scientist with the Illinois State Police, and she taught the girls how to decode a ransom note.

The missing person was Rocky the stuffed dog, and no one could find him anywhere, until the S4S girls received a ransom note. The note said that in order for them to have Rocky back, they would have to pay $1000. Calumet4The girls, unwilling to give up that type of money, decide to seek the help of Angela Cloud-Simmons to figure out who had Rocky. After seperating the marker colors with the chromatography experiment, they were able to determine that it was Table 3 of S4S girls!! Once caught, they released Rocky, and no one was punished!Calumet2

Angela also spoke to the girls about her job specifically, even about the hand the coroner cut off and sent to her for fingerprints. They loved that! A great session, very informative, but most importantly, FUN!!Calumet5

Chromography

By Brienne

This week in the world of the S4S Perspectives Calumet Girls!

This week, we played with markers, or at least its content! We learned about Chromography and how it takes many colors to make one! The activity called for the girls to color a strip on a piece of filler paper (we used good ole paper towel!), sit it in a little bit of water, and watch the colors rise and separate on the paper. Both the girls and I were extremely amazed and in awe as we watched colors we never thought would be included in a color appear on the paper! The girls left with even more knowledge on how things are made and the science behind the most simple of things like a marker, and a new and cool way to tie-dye!! Yet another great day at Perspectives Calumet!

Slime Time

By Brienne

Welcome to the world of the S4S Perspectives Calumet Girls!

At Perspectives Calumet, we are busy divulging in the world of Physics and learning how things are made. The S4S girls also did the project utilizing only marshmallows, dry spaghetti and a piece of ribbon. It was an ooey gooey good time, even though everyone wasn’t successful in getting theirs to stand. Of those who did, the highest height was 14” and it didn’t move an inch when we all took turns blowing on it! In addition to diving into the physics of the activity, we also took a deep look into the science and makeup of a marshmallow, and why it was able to act as a glue or mortar for their spaghetti structures! The girls journaled and I then shared some research about it, and they were amazed by the science of it all! I took forever to get all the marshmallow off of the table, but the girls walked away with a great new experience and more knowledge!
