Water Movement in Different Simulants Part 1
Overview
This is the first in a series of experiments comparing water movement in Lunar regolith simulant, Mars regolith simulant and ISS-VEGGIE growth substrate inside and outside of microgravity environments. Students learn to understand the effects of these environments on capillary action, or upwards water movement, as well as the mechanics of force and motion and the influence of gravity on water diffusion. Ms. Tomlin had the opportunity to test these student experiments in different microgravity environments aboard a 0-g flight. This project allows students to investigate regolith behavior on Earth, as well as consider its behavior off world.
