Neutral Buoyancy & Simulated Weightlessness
In this activity, students are introduced to NASA research that uses water immersion experiments to study the effects of weightlessness on the vascular system. The goal of the activity is to build a model of a closed vascular system that has neutral buoyancy. This model consists of a drinking straw filled with air and yellow water and suspended in a tub of clear water. By experimenting with different amounts of water in the straw, students will calculate the ratio of air to fluid needed to attain neutral buoyancy.
