Document Summary

List the components of water intake and water output. In your own words, describe the hormonal regulation of water balance. List two situations in which thirst is not a reliable indicator of fluid needs. Ai for total water (fluid and food): women: 2. 7 liters per day (11 cups, men: 3. 7 liters per day (15 cups) Fluid alone: women: 2. 2 liters (9 cups, men: 3 liters (13 cups) Many fruits and vegetables: more than 80% water. Many meats: at least 50% water: figure 9-5: sources of water from myplate. Vegetables: potatoes, lettuce, tomatoes, squash, green beans, vegetable juices. Protein: oranges, apples, bananas, melons, plums, fruit juices, milk, yogurt, beef, poultry, seafood, beans, water output. Urine excretion greatest output: average urinary water loss per day: 1,950 milliliters (8. 5 cups, output below 500 ml is the sign of dehydration. Through skin as perspiration (insensible: about 1 liter each day. Adh signals the kidneys to retain more water fluid balance is restored: fluid conservation.

Aim: To Analyze Tyndal Effect, Hardness of Water (Metal), germination and growth of seeds using water from Different source. Sample:
1. RO water
2. RO Waste water
3. Tap water
4. Water collected by washing vegetables and fruits.
5. Water from aquarium (fish tank).

PROCEDURE: Collect samples of water about 100 add 50ml of each sample separately in a
glass tumbler. Add 1 drop of dye to each sample and note the colour change and different
among the colors formed in each glass.
Dip the cloth in the coloued water and dry the cloth to analyse the colour variation
Add soap solution to each sample separately and check lather formation.
Sample Intensity of colour Lather formation using soap

Intensity of colour- (light, dark, darker)
To analyze Tyndale effect, take samples of water separately in the glass tumbler and place it
again the white background (screen). Now allow the light pass through the glass of water in
such away that is has to fall on to the screen.

Note the variations among the intensity of the light while passing to different samples of water.
To analyze the effect the samples of water on seed germination.
Take samples of water separately in a separate glass tumbler soak the seeds for 8 hours then
keep the seeds on tissue paper separately and sprinkle the sample water to find the effect of
water on germinating seeds.

Germination rate ( Slow, fast, faster)
Draw inference referring to the points given below
Germination of seed requires water with nutrient
Lather formation shows mineral salt in water
Colour variation in water after adding dye shows density of water
Intensity of light shows presence of colloidal particles in water.

Questions:
Which water sample is most suitable of seed germination?
Which water sample contains more mineral salt to increase its hardness?
Which water sample is denser?
Which water sample shows more colloidal particles?
