Students with pumpkin
UCLA Chemistry & Biochemistry students visited the local elementary school to demonstrate experiments with a Halloween theme.
 
At the outreach event at the Warner Avenue Elementary School on October 22, 2019, members of Professor Neil Garg's group talked to the second-graders about matter and laboratory safety after which the young scientists suited up in lab coats and safety glasses to learn about the properties of gases, liquids, and solids.  
 
The UCLA organic chemistry graduate student participants were Milauni Mehta, Andrew Kelleghan, Katie Spence and Allison Hacker, as well as Garg group undergraduate researchers Ana Bulger, Matt McVeigh, and Laura Wonilowicz. Garg's 7-year-old daughter Kaylie, a student at the school, was on hand to help her classmates with the demonstrations.

The students cooled a balloon with liquid nitrogen and watched it contract, shattered frozen rose pedals, observed a ’spooky pumpkin’ demonstration to learn about condensation, and made ‘lava lamps’. The children made hypotheses and explained their observations along the way (before eventually acing a quiz).  
 
All the children received a few small souvenirs, including a copy of the organic chemistry coloring book that Garg and Kaylie and her sister Elaina wrote, custom-designed chemistry stickers, and a glow stick.
