Read It! Station DirectionsEach member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section.
It is important to remember that the answers will come directly from the reading passage.
The Importance of HydrationYour body depends on water to survive. Every cell, tissue, and organ in your body needs water to work correctly. For example, your body uses water to maintain its temperature, remove waste, and lubricate joints. Water is needed for good health.
Water makes up more than half of your body weight. You lose water each day when you go to the bathroom, sweat, and even when you breathe. You lose water even faster when the weather is really hot, when you are physically active, or if you have a fever. Vomiting and diarrhea can also lead to rapid water loss. If you don’t replace the water you lose, you can become dehydrated.
Symptoms of dehydration include the following: little or no urine, or urine that is darker than usual, dry mouth, sleepiness or fatigue, extreme thirst, headaches, confusion, and dizziness.
You may have heard different recommendations for daily water intake. Most people have been told they should drink 6 to 8 8-ounce glasses of water each day, which is a reasonable goal. However, different people need different amounts of water to stay hydrated. Most healthy people can stay well hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than 8 glasses may be enough.Other people may need more than 8 glasses each day. If you are concerned that you are not drinking enough water, check your urine. If your urine is consistently colorless or light yellow, you are most likely staying well hydrated. Dark yellow or amber-colored urine is a sign ofdehydration.
For most people, water is all that is needed to maintain good hydration. However, if you are planning on exercising at a high intensity for longer than an hour, a sports drink may be helpful. It contains carbohydratesand electrolytes that can increase your energy and help your body absorb water. Choose a sports drink wisely. They are often high incalories from added sugar and may contain high levels of sodium. Also, check the serving size. One bottle may contain several servings.
Sports drinks are not the same as energy drinks. Energy drinks usually contain large amounts of caffeine and other stimulants (for example, guarana, ginseng, or taurine) that your body doesn't need. Most of these drinks are also high in added sugar. Many experts recommend that children and teens should not have energy drinks.

Use diagram #1 and #2 for the following questions.
1. What body system is represented in the diagrams?
2. What do you think the main purpose of that system is?
©KeslerScience.com
The function of the excretory system is to filter the waste out of the blood and remove it from the body. It is sometimes called the urinary system.
The kidneys are the bean-shaped organ near the top of the diagram. Their job is to filter out waste from the blood and send the urine away for removal.
1. Do you think we need both kidneys to survive?
©KeslerScience.com
After the urine has been created it is sent down the ureters (small tubes that connect the kidney andbladder) to the bladder.
The bladder acts as a storage for urine until it gets to the point where it fills upand needs to be removed. From there it
is sent out the urethra and out of the body.

body.
