Building your own station Weather: rain and sun

© Sandrine New

To study the weather, meteorologists record and analyze data. It is possible to become an amateur meteorologist without spending a fortune on measuring instruments in constructing its own weather station and taking note of his actions.

This series of articles showing how to build some instruments for measuring weather station. While not extremely accurate, of course, these instruments may nevertheless be used to measure weather conditions and to provide time to come.

Most instruments are simple enough to be built with children - sometimes with a little help - for a project to do at home or at school.

This article speaks of instruments used to measure rainfall and intensity of solar radiation.


1) Measuring Precipitation (Build a Rain Gauge)

The amount of water or snow that has fallen is measured with a rain gauge. Regularly checking the level of the gauge, we can know how much rain fell during a rainstorm one day, week, or month.

Puviomètre a measuring instrument is a very easy to build, but be careful in his choice of location: Any graduated glass left outside can serve as a gauge, but like many showers are accompanied by wind, it should well secured the gauge. In addition, it must be placed in an open area without the overhanging (as a tree or roof ...), which could change the amount of water that enters the gauge. A rain gauge can be placed, for example, on a pole or along a fence, away from any building.

Two examples of rain gauges build:

Model A:

must:

- a glass measuring cup or container with straight edges, which can be graduated.
- a rule
- tape
- (permanent marker)


1. If a single container is used, it must be the graduate (starting from the bottom) with the marker and a ruler or place within the rule so that it rests at the bottom.

2. Attach the ruler in place with adhesive tape.
If the scale of the rule not begin exactly at the edge, it will either keep some water in the bottom of the gauge, 0 to the rule, or compensate by adding (0.5 or 1 cm ...) to your measurements. It is possible, alternatively, to set the rules outside of the container (which must be transparent) so that 0 corresponds to the bottom of the gauge.


Model B:

must:

- long plastic bottle with straight edges
- a rule
- sharp scissors

Instructions:


1. Cut the neck of the plastic bottle in his mouth environ10 cm.

2. Place the cut down on the body of the bottle to form a funnel. The funnel helps direct water into the bottle and limit evaporation.

3. Burying the base of the bottle into the ground in an open area away from any tree or building. Use a ruler to measure the amount of rain that fell each day.

To measure the amount of snow, the funnel is not helpful. Use the following approximate conversion: 10 cm of snow = 1 cm of water.


2) Measuring Solar Energy (Building a Radiometer)

A radiometer is an instrument that uses refraction and absorption to measure the energy Sun.

must:

- a pen (or marker) black
- paper packaging of chewing gum
- a pot of jam
- a pencil (or stick with dimensions close)
- the glue
-
thread - a match used
-
scissors - tape

Instructions:

1. With the pen, colored in black the non-metallized paper of chewing gum. Cut the paper into 4 equal pieces, measuring about 2cm x 2.5 cm each.

2. Glue the 4 pieces at one end of the match, one on each side, as to form the blades of a propeller or the spokes of a bicycle. The shiny side should not face each other.

3. Hook the wire to the other end of the match (if necessary, make a small incision in the match to keep the wire from slipping). Wrap the loose end of wire around the pencil. Secure with tape.

4. Suspend the radiometer in the cookie jar (pencil horizontally). Place the pot dan a sunny location.


Explanations:

The radiometer turns when solar energy is absorbed by black surfaces and refracted by shiny surfaces. More solar energy is stronger, it turns quickly.

Build your own weather station: temperature and pressure

© Sandrine New

To study the weather, meteorologists record and analyze data. It is possible to become an amateur meteorologist without spending a fortune on measuring instruments in constructing its own weather station and taking note of his actions.

This series of articles show how to build some instruments for measuring weather station. While not extremely accurate, of course, these instruments may nevertheless be used to measure weather conditions and to provide time to come.

Most instruments are simple enough to be built with children - sometimes with a little help - for a project to do at home or at school.

This article speaks of instruments used to measure air temperature and atmospheric pressure, or thermometers and barometers.


1) Measuring Air Temperature (Building a thermometer)

The air temperature is measured with a thermometer. The thermometer should be placed outside in a protected and shaded, as the north face of a building - in the Northern Hemisphere, face south to the Southern Hemisphere). An alternative would be to place the thermometer in the bottom of an airtight container to serve as a weather station.

course, it is easy and not too expensive, buy a thermometer, but it can be fun and instructive to build one.

must:

- a glass bottle (like a bottle milk)
- ink, dye or other
- a drinking straw
- paw shape
- white cardstock
- glue

Instructions:

1. Fill the bottle with colored water.

2. Insert the straw into the bottle and keep it upright with the leg) model.

3. Glue the cardstock to the straw to better see the variations in water level.


Explanations:

When the air temperature rises, the water level in the straw is also increasing. And vice versa. To improve the thermometer, it is possible to benchmark on paperboard by comparing with a "real" thermometer.

2) Measure Pressure atmoshere (Build a barometer)


Atmospheric pressure is measured in millibars millibars or using a barometer.
Changing the air pressure helps to predict the time to come. A pressure drop is usually a looming depression - an area of low pressure - which tends to bring clouds and precipitation. In contrast, pressure increases normally announces an area of high pressure synonymous with time cleared or remains stable and beautiful. The barometers are

very sensitive to the slightest climatic variation, it is better to keep them inside to get a more reliable reading. Better to avoid it, too, placing them near a window, because these instruments are sensitive to both temperature and air pressure.

Here is a selection of three models of barometers.

Model A:

must:

- a long narrow plastic bottle
- a plastic bowl or other container large enough
- 2 elastic
- cardboard
- Water
- a rule


Instructions:

1. Cut a strip of cardboard approximately 2.5 cm wide and graduated in using the rule. Attach along the bottle with rubber bands so that the graduations begin at the top of the bottle. Alternatively, the rule can be glued directly on the bottle.

2. Fill the bottle with water to 3 / 4 bowl and almost entirely.

3. By closing the bottle with your hand to prevent the water to escape, return and place in bowl with its mouth under water. Remove your hand and leave the bottle in the basin. Note the water level in the bottle.

Explanation:

The water level in the bottle rises and falls with the air pressure exerted the basin. When the pressure increases, the water level in the bottle augment. When the pressure decreases, the water level of the bottle down.


Model B:

This barometer works exactly like its predecessor, it is only a little more sophisticated and at a smaller scale.

must:

- a plastic or glass container with straight sides (or a measuring cup cooking)
- a rule of 30 cm
- scotch
- a clear plastic tube 30 cm long
- chewing gum
- Water

Instructions:

1. Place the rule in the container and tape against the wall.

2. Tape the plastic tube the lond of the rule (above) by placing the tip about 1 cm from the bottom.

3. Fill the container with water halfway. Sucked into the plastic tube, like a straw until it is half filled with water. Trap water in the tube by closing the opening with chewed gum.

4. Note the water level in the tube as indicated by the rule.


Explanations:

The water level in the tube changes with variations in pressure exerted on water in the container. When the pressure air increases, the air pushes harder on the water in the container, and more water is sent into the tube: the water level rises. When the pressure exerted on the water container decreases, part of the water trapped in the tube spring and the measured level drops.


Model C:

must:

- a jam jar or a small coffee can
- a piece of balloon or plastic film
-
of Scissors - a big rubber band
- glue (which does not attack plastic) or tape
- a drinking straw
- a piece of cardstock
- tape or tacks
- a red pen and a blue or black pen


Instructions:

1. Stretch the balloon / plastic film on top of the jam jar and hold it in place with elastic. This cover must be tight, and should not pass air.

2. Put a drop of glue (or use tape) in the center of the ball and press one end of the straw above, by placing it horizontally. 2 / 3 of the straw must be on the pot.

3. Tape or pin up the cardstock on a wall (or other vertical surface) and place the free end of the straw against the cardboard.

4. Mark the location of the straw on the map. Make a red mark corresponding to the horizontal position of the straw and the dim card every 5 mm in black or blue, above and below the central red mark. Write "high pressure" at the top of the box and "low pressure" below.

Explanation:

When the air is pressure (high pressure) on the surface of the ball, it makes its concave surface and the free end of the straw rises. A low pressure, however, inflates the balloon surface, and the free end of the straw down.

Rooibos Tea is, indeed, very versatile. It can be enjoyed hot or cold, with or without milk, sugar or honey. The South African herbal tea blends well with lemon juice or fruit and can also be used in cooking and baking. It can even replace the liquid element in many recipes for soups, marinades, sauces, stews and cakes for added flavor and elements nutrients.

In South Africa - and increasingly abroad - the consumer can now try many innovative products made from Rooibos: Rooibos in the yogurt, fruit juice, rooibos, honey infused to Rooibos, or even a Rooibos espresso, candy carob-infused Rooibos, Rooibos of nougat, as well as products for skin and hair that contain tea.

So why is it that Rooibos has become a product if desired? Because this tea has very good taste, of course, but even more because it is extremely good for your health and we found there, including elements anit-mutagenic, anti-carcinogenic, anti-inflammatory and anti-virals.
In fact, medical science is only beginning to entrevioir all the benefits of Rooibos. Current research seems to confirm that there are no limits to its incredible medicinal properties.


What is Rooibos?

Rooibos - pronounced "king-boss" - meaning "red bush" in Afrikaans.
This tea comes from the Aspalathus linearis bush, which grows on the slopes of the Cederberg mountains in the Western Cape, South Africa. We can not find anywhere else.

Rooibos is not strictly speaking a "real" tea, since it is extracted from a plant to flower without a wooden rod. Infusions of teas contain no caffeine, unlike other types of tea.

The Koi people make mountains Cederberg Rooibos teas for hundreds of years, and they have long been convinced that this tea is good for their health. The Contributions of



Rooibos - Rooibos has no side effects listed

Researchers have, to date, found no side effects to Rooibos tea, so it can be drunk without restriction.
In fact, Rooibos is completely pure and natural: it contains no added material, No artificial colorings or preservatives. It is naturally low in tannin (barely 1-4%) whereby it does not prevent the absorption of iron and protein in the body - unlike black tea. This "bush tea" contains no caffeine or oxalic acid, and can therefore be drunk by people suffering from kidney stones. Furthermore, Rooibos contains, so to speak, no calories (unless you add sugar or milk, of course).

- Rooibos delays aging of the organism

Our bodies are aging under the action of toxic compounds called free radicals - a residue of normal operation -cells. Free radicals attack our healthy cells and gently help us to age and weaken our immune system.

Now, Japanese scientists have recently discovered that Rooibos contains an imitation of the enzyme SOD (Super Oxide Dismutase), an antioxidant that attacks free radicals and limit their devastating effects.
Rooibos contains 50 times more SOD than green tea and other anti-oxidants - as aspalathin - which are not found in other teas.
Rooibos Tea is also rich in flavonoids, and studies have shown that it contains much polyphenol - another element valuable to health - that green tea.

experiments - so far carried out almost exclusively on animals, show that Rooibos can slow the aging process (in particular the progression of dementia), decrease the risk of certain cancers (such as cancers of the skin, faith, esophagus and prostate) and give some protection against cardiac events.

- Rooibos is good for the digestive system

do not contain caffeine naturally, Rooibos helps to relieve stomach cramps, ulcers, nausea, heartburn, and constipation . This
tea also helps recover from a hangover and can be beneficial for weight loss by helping to control appetite without adding calories.

- Rooibos is good for the nervous system

Rooibos is rich in magnesium, which is necessary for the proper functioning of the nervous system. In addition, it contains no caffeine and has a relaxing effect on the central nervous system.

Apparently, Rooibos helps fight against insomnia, restless nights and headache. It is recommended in cases of irritability, nervous tension, mild depression or hypertension, because its relaxing sedative.

- Rooibos contributes to bone health

Rooibos helps strengthen bones and teeth because it contains calcium, manganese and especially fluoride.

- Rooibos is ideal for skin problems

alpha hydroxy acid and zinc present in Rooibos helps to keep skin healthy and smooth. Rooibos also has a calming effect in skin irritations such as eczema, sunburn, diaper rash or acne. It is necessary in these cases, apply directly to the affected area.

- Rooibos can help in the case of allergies

Rooibos seems to help control allergies: hay fever, asthma, eczema.

- Rooibos does wonders for babies

Rooibos is not only safe for pregnant or nursing women and babies: because of its anti-spasmodic it is even recommended - mixed with milk breastmilk or infant formula milk powder - for babies with colic, stomach cramps or fighters have trouble sleeping.

- Rooibos can relieve tired eyes

Packets of Rooibos can be placed on the eyes tired or red to pacify and relax. It's more effective if the bags are first placed in the fridge or fridge.

- Rooibos helps our body to function properly

Rooibos promotes iron absorption by the body. It also contains potassium and copper required for certain metabolic functions.
Because it is rich in minerals - iron, potassium, zinc, manganese and sodium - the tea bush in South Africa is helping to restore balance to the body after exercise sports.

- and Rooibos tastes divine!

It is less bitter than most teas and can be consumed at any hour of the day for a welfare maximum.
