MOSH Molecules Fall 2022 & Spring 2023

Happenin’ Habitats

Have you ever wondered what kinds of things baby dinosaurs, birds, and humans all need in order to survive and thrive? In this program series, you will learn about creatures from both the past and the present through their behaviors, fossils, and “homes.” Together we will investigate creatures’ features and discover how human needs are like those of our animal friends. During the program you will have guest visits from our Florida Naturalist Center, create model habitats for animals of the past and the present, and use your imagination to “make up” a future creature and its habitat to take home. You will gain knowledge about many forms of life on this planet and what all living things have in common.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.

The Motion of the Ocean

What is “the ocean,” and how does it affect life here in Northeast Florida? What lives in the ocean, and how do they survive in the world hidden beneath the waves? Uncover the answers to these questions and more through this program series. In addition, you will create models of ocean habitats, explore how waves form and move in water, and investigate the adaptations and features of ocean life through hands-on activities.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.

Earth, Moon, & Sun

What makes Earth not too hot and not too cold, but “just right” for us to live on? In this program series, you will explore our Earth, the Sun, and the Moon, as well as the connections between them. Together we will investigate life on this planet we call home and will also blast off to the Moon in our Bryan-Gooding Planetarium. During the program you will explore ways in which the Sun and our Earth relate to each other, and why life would not look the same on the Moon. You will gain both investigative skills and knowledge of our Solar System through many hands-on activities.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.

Be the Builder

Put on your construction hat and join MOSH in the world of engineering! Using everyday materials, like drinking straws and spaghetti, students will discover the mathematical world of two-dimensional and three-dimensional geometric shapes. You will apply your newfound knowledge as you construct towers, bridges, and put your engineering designs to the test by applying weights, forces, and structural changes to your creations. Through hands-on learning, you will gain knowledge of the engineering design process.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.

Exploring the Four Seasons

What are the seasons of Earth, and what causes them? Why do some seasons feel colder or warmer than others? Do other planets, like Mars or Jupiter, have seasons like the Earth does? In this program series, you will investigate the changing seasons through hands-on experiments, construct models of the Earth-Sun relationship and see this relationship in action in the Bryan-Gooding Planetarium, build an understanding of how air can move and shape our weather and climate, and gain deeper knowledge of how the seasons influence all aspects of the Earth’s natural world.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.

Rolling Robots

In this program series, you will learn how robots can move on their own or by communicating with people through commands, and you will explore these methods of motion by testing out various types of robots, such as Ozobots, Bee-Bots, Spheros, and more. You will put your robotics skills to the test by competing in a series of robot relay races. You will gain familiarity with various technologies that power robots and machines and build an understanding of the relationship between humans and robots.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.

Our Super Senses

You will come to your senses in this multidisciplinary program that teaches the biology of the five senses through hands-on science experiments and lessons. You will see the color spectrum through prisms, hear sound waves in action, feel the chill of freezing cold liquid nitrogen, and put your senses to work in order to make observations and discoveries about the world around you. You will gain knowledge about the many ways in which our senses inform science and our interactions with the larger world.

  • Wednesdays at 9:30 a.m.
  • Saturdays at 10 a.m.
