The second full day of Sigma has now passed! Campers woke up to a rainy morning, but we didn’t let the rain spoil our fun! After breakfast, they headed to their semilabs, where they got to learn about fingerprints, strategies in game theory, and made sulfuric acid! Experiment of the day today was extra cool because it used liquid nitrogen ;). After a break of games and relaxing in the cabins, campers headed to lectures where they learned about neural engineering and entropy. Then, full after a barbeque-style lunch, campers headed to their second semilabs. For the Sigma Tournament, campers competed in the biology and chemistry categories. Later in the day, campers headed to their workshops where they made parachutes, controlled each other's arms, and learned about music theory. During evening clubs, campers learned west coast swing and how to make cubane. What a full and exciting day!
