AIChE at USC is the "chemical engineering club" at the University of Southern California. It is a local chapter of the larger organization known as the American Institute of Chemical Engineers (AIChE), which supports students studying and interested in chemical engineering. AIChE at USC wants to increase its outreach efforts and connection to the local community. As a STEM organization, it feels that teaching science and engineering to young people is a great way to give back. Everyone in AIChE at USC is eager to partner with A Place Called Home to excite students about a fascinating field that needs young and enthusiastic minds now more than ever!

Can salt really make ice colder? Try this simple experiment. Take 2 bowls. Fill each bowl with ice cubes. Choose one bowl to put a 1/4 cup of salt. Mix it around and wait a couple of minutes. Put one hand in each bowl. Which one feels colder? Now use a thermometer to check the temperatures of the ice in each bowl. Which one is colder?

Plastics are everywhere around us. Just in our homes there are garbage bags, cups, disposable bottles, combs, game controllers, straws, and even clothing – all made from plastic. But as different as plastics can look and feel, they are similar in two ways: 1) they are a material that can be molded into many shapes, and 2) they are all made up of polymers, which are molecules that are repeated over and over again in a chain.
So what are plastics made of and how are they made? Try this week’s experiment to turn milk into plastic (yes, really!) and check out the videos to find out.

This week's experiment was an introduction to the concept of hydrophilic and hydrophobic interactions. If you missed out on joining our Zoom meeting, read the directions and watch the video from Kruthi below. You can also take a look at two videos to learn more about this scientific concept, including how it is used in the real world to help animals that are affected by oil spills.
