Hydration Station

Since our bodies are made up of 50 to 70% water, it is essential to drink plenty of fluids to keep our bodies healthy. Water plays many important roles in keeping our body in peak performance by giving nutrients to our cells, muscles, joints, our brain, skin and kidneys. Water also regulates our body temperature, and helps our heart function properly.
Space explorers must maintain proper hydration levels while in space. As astronauts complete their tasks on an exploration mission, whether inside or outside the space exploration vehicle, astronauts need adequate hydration to maintain proper health.
In this investigation, teams will explore the importance of staying hydrated here on Earth and in space. They will also learn to identify the signs of dehydration. 
Mission Question
How can I create simulated urine to identify different levels of hydration?
