Hydration

Hydration is the process of providing an adequate amount of water to the body in order to maintain proper function and health.

Importance of Hydration

Water is essential for the body's overall function. It helps regulate body temperature, aids in digestion, removes waste, and lubricates joints. Proper hydration is also important for cognitive function, physical performance, and overall well-being.

Factors Affecting Hydration

Physical activity: The more active a person is, the more water they need to maintain proper hydration.
Climate: Hot and humid weather may increase the amount of water lost through sweat, requiring increased hydration.
Diet: Certain foods and drinks can contribute to hydration, while others may have a diuretic effect, increasing the need for water intake.

Signs of Dehydration

It's important to recognize the signs of dehydration, which may include thirst, dry mouth, fatigue, dizziness, dark urine, and decreased urine output.

Ways to Stay Hydrated

Drink plenty of water throughout the day.
Consume hydrating foods such as fruits and vegetables.
Avoid excessive consumption of caffeinated or alcoholic beverages, as they can contribute to dehydration.
Monitor urine color - pale yellow to light straw color indicates proper hydration.

PHYSICAL SCIENCE

Motion and Stability: Forces and Interactions

Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).

Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).
