Water is important for healthy digestion. RELATED: Are You Drinking Enough Water? These Are the Health Risks of Dehydration 3. However, as research notes, there is no evidence to prove that increasing your fluid intake will cure constipation. Water is also important for helping prevent constipation, points out the University of Rochester Medical Center. Water helps your kidneys remove waste from your blood and keep the blood vessels that run to your kidneys open and filter them out, according to the National Kidney Foundation. Water Helps Your Body Remove WasteĪdequate water intake enables your body to excrete waste through perspiration, urination, and defecation. In addition, water helps protect the spinal cord, and it acts as a lubricant and cushion for your joints. You know how it feels when your eyes, nose, or mouth gets dry? Keeping your body hydrated helps it retain optimum levels of moisture in these sensitive areas, as well as in the blood, bones, and brain. Water does more than just quench your thirst and regulate your body's temperature it keeps the tissues in your body moist, according to the Mayo Clinic Health System. Water Protects Your Tissues, Spinal Cord, and Joints As they observe the flower and celery leaves change color over time, they will realize that plants meet their need for water by transporting it up from their roots, through tiny tubes in their stem, to the leaves, and the top of the plant.1. Then they will be able to watch how the flower and leaves change color as the water moves through the plant. They will let a white flower and a leafy celery stalk sit in dyed water. In this lesson plan, students will be able to observe this water movement through the stem of a plant. This process allows plants to move water to tree canopies more than to 100 meters above the soil surface! As more water evaporates, the plant pulls up more and more water. As a result, the combined cohesion and adhesion forces create a constant chain of water molecules moving up the plant. Capillary action happens when the forces binding the water molecules together (cohesion and surface tension) and the forces attracting the water to the xylem surface (adhesion) are greater than the force of gravity. This is possible due to capillary action. However, for water molecules to travel up the xylem, they have to overcome gravity. The water leaving the plant creates a suction force that pulls more water upward.
Transpiration is when the water from the leaves and flower petals evaporates. The driving factors that make water move through the xylem are transpiration and capillary action (Figure 1). Water path through a plant driven by transpiration and capillary action. The shape and stability of structures of natural and designed objects are related to their function(s).įigure 1. Plants depend on water and light to grow. LS2.A: Interdependent Relationships in Ecosystems. Record information (observations, thoughts, and ideas). Make predictions based on prior experiences. Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence to answer a question. Planning and Carrying Out Investigations. This lesson focuses on these aspects of NGSS Three Dimensional Learning: Science & Engineering Practices Plan and conduct an investigation to determine if plants need sunlight and water to grow.
This lesson helps students prepare for these Next Generation Science Standards Performance Expectations:
