![]() ![]() The water based inks in this project are also moving when exposed to water but they move by diffusion- the movement of particles from an area of high concentration to an area of low concentration. Just like a wilted plant expands and perks up when it is finally watered, the fibers in our paper flowers swell and expand when placed in water, causing the flower to open!ĭiffusion is very similar to osmosis but osmosis refers strictly to the movement of water. Since paper is made from wood fiber, when it is placed in water it absorbs the water until it every fiber is wet. The process of osmosis continues until the water has reached a state of equilibrium. Plants absorb water through a process called osmosis, this is the movement of water across a membrane from an area of high concentration to an area of low concentration. Paper is made from trees (wood) that has been ground into a pulp and dried. Let’s Talk STEAM The Science Absorption and Osmosis
