STEM Discovery Day at CU

Taught two groups of 7th graders about proteins, see some photos of their work! Lots of fun!

Coagulating casein with vinegar and filtering from milk!

Main group only Periodic table using Legos

The blue pieces represent valence electrons, you can see metals (green), metalloids (red), and nonmetals (white) AND this version shows the building up of each principal energy level!

ACS webinar AND 2 seminars upcoming that would be good for CHE class extra credit!

There is another segment on the A-Z of Drug discovery tomorrow (March 27):
