March Science Saturday was a hands-on science event presented by the Florida Museum of Natural History. Dr. Verity Mathis, the Mammal Collections Manager at the museum, led activities about determining mammal intelligence from the ratio of cranial volume to body mass. The Silver River Museum in Ocala lent us a variety of mammal skulls, and Dr. Mathis brought a dolphin skull from the museum collection. We conducted experiments that let us conclude that dolphins are truly brainiacs among mammals, both on land and in the sea.

The topic of IHMC's February Science Saturday was computer game design. This event was taught by Ian Perera, a computer scientist who works in the filed of natural language processing. Students learned basics of the scratch programming language, including loops and if-then statements.

The fall season of Ocala Science Saturdays started in October, with Monarch Butterflies. Rob Wood joined us virtually from San Diego to lead the session. Hands-on activities included observing monarch caterpillars and planting seeds for participants to take home to start butterfly gardens. Two types of native milkweed seeds were donated by St. Marks National Wildlife Preserve near Tallahassee - butterfly milkweed and swamp milkweed. Milkweed is the only plant on which monarchs lay eggs, so it's critical for habitat restoration. We also planted seeds for nectar plants favored by monarch butterflies, including zinnia, goldenrod, and coreopsis. Starbucks and Publix donated supplies. An exciting surprise was getting to see one of the caterpillars make it’s chrysalis. Photos by Brooke Heller.

The April topic was changed in response to the social distancing requirements of COVID-19. Families received instructions for an experiment at home, in which they monitored the growth of bacteria on bread. The bacteria was from their unwashed hands, cell phones, hands cleaned with hand sanitizer, and hands washed with warm water and soap. Participants were surprised to discover that unwashed hands spread bacteria than cell phones, and that washing hands with warm water and soap transferred much less bacteria than using hand-sanitizer. A few families sent photos.
