In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles. Learners can explore the characteristics of buoyancy by adjusting amounts of air and salt water. Learners also investigate the types of information that robots can gather and learn how scientists use this information to understand the ocean.
