Terrariums.



Terrariums are little gardens. The plants grow in covered containers. It's fun to make your own! The container can be glass or plastic and needs a lid. Put rocks or gravel on the bottom, then add soil. Now it's time It's Time was a successful political campaign run by the Australian Labor Party (ALP) under Gough Whitlam at the 1972 election in Australia. Campaigning on the perceived need for change after 23 years of conservative (Liberal Party of Australia) government, Labor put forward a  to plant!

Plant different kinds of small plants. Leave enough space around each one for it to grow. Mist with water until the soil is damp, but not too wet. Then put on the lid.

Inside your terrarium terrarium, a miniature garden in an artificial environment, in which small plants and animals may be kept as ornament or for educational purposes. Fish bowls, small fish tanks, large bottles, and carboys are often employed as containers for terrariums; such vessels , the plants have everything they need to live, such as air, water, and light. The glass traps the water that the plants need. When the drops of water get big and heavy enough, they drip down onto the plants. Now, it's raining in your terrarium! This is just like what happens on Earth. Drops of water form clouds, and then it rains. This is called the rain cycle.

On Earth, we have about the same amount of water as we had millions of years ago! Water is constantly being recycled. Terrariums work the same way. This is why you don't need to add water very often.

Background

History of Terrariums

Terrariums were popular in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area.  during the 1960's and 70's. Now that bellbottoms and macrame are stylish once again, is it any wonder that terrariums are back in vogue Vogue

 too? Today, thanks to the efforts of plant breeders, terrarium owners can find a much greater variety of miniature plants than ever before.

Like many other useful things, terrariums were invented by accident. In 1829, Dr. Nathaniel Ward The Reverend Nathaniel Ward (1578 — October 1652) wrote the first constitution in North America in 1641.

He was born in Haverhill, Suffolk, England. He studied law and graduated from Cambridge University in 1603.
 was studying the life cycle of the sphinx sphinx (sfĭngks), mythical beast of ancient Egypt, frequently symbolizing the pharaoh as an incarnation of the sun god Ra. The sphinx was represented in sculpture usually in a recumbent position with the head of a man and the body of a lion,  moth when he noticed tiny ferns growing in a sealed bottle, which hadn't been watered in 4 years! Dr. Ward lived in London, where the heavily polluted pol·lute

Terrariums proved to be practical and not just pleasant decorations. Many attempts by explorers and traders to bring plants back home by ship from foreign lands had failed. However, the Wardian cases solved that problem, protecting the young plants from salt spray and drying winds. The cases also kept the plants moist moist

Life in a Terrarium

A terrarium provides everything plants need to live. Minerals come from the soil, and perhaps from an occasional dose of weak fertilizer fertilizer, organic or inorganic material containing one or more of the nutrients—mainly nitrogen, phosphorus, and potassium, and other essential elements required for plant growth.  (too much fertilizer causes the plants to grow too fast). Sunlight comes in through the clear glass or plastic. Unlike houseplants growing in pots, terrariums should never be placed in direct sunlight, because the temperatures in the sealed container will get too high, "cooking" the plants and encouraging the growth of algae algae (ăl`jē) [plural of Lat. alga=seaweed], a large and diverse group of primarily aquatic plantlike organisms. These organisms were previously classified as a primitive subkingdom of the plant kingdom, the thallophytes (plants that  on the walls.

The sealed case of a terrarium traps water, making this type of gardening good for those of us who forget to water our plants. In fact, one Wardian case lasted 18 years without having any water added! Air is also trapped inside. At night, plants use oxygen from the air to produce carbon dioxide. During the day, the plants use the carbon dioxide, plus sunlight and chlorophyll, to make food and oxygen (photosynthesis). Sometimes people have more than plants growing in their terrariums. When animals such as lizards, snakes, and spiders are added, these closed environments are called vivariums.

The Weather Cycle

The weather cycle in a terrarium is much like Earth's rain cycle, just on a smaller scale. The cycles consists of transpiration transpiration, in botany, the loss of water by evaporation in terrestrial plants. Some evaporation occurs directly through the exposed walls of surface cells, but the greatest amount takes place through the stomates, or intercellular spaces (see leaf). , evaporation evaporation, change of a liquid into vapor at any temperature below its boiling point. For example, water, when placed in a shallow open container exposed to air, gradually disappears, evaporating at a rate that depends on the amount of surface exposed, the humidity , condensation, and precipitation precipitation, in chemistry
precipitation, in chemistry, a process in which a solid is separated from a suspension, sol, or solution. In a suspension such as sand in water the solid spontaneously precipitates (settles out) on standing.
.

Transpiration is the moving of water up from the roots of a plant and out through the leaves. As the water moves up through the plant, it carries minerals with it. Once water reaches the leaves, it escapes through tiny holes called stomata sto·ma·ta  
n.
A plural of stoma.
. Only 10% of the water taken up by the roots is used for photosynthesis and growth. The other 90% is lost through transpiration.

Various factors can affect the rate of transpiration. High temperatures increase transpiration, while high humidity humidity, moisture content of the atmosphere, a primary element of climate. Humidity measurements include absolute humidity, the mass of water vapor per unit volume of natural air; relative humidity (usually meant when the term humidity  decreases it. In the outdoors, wind is a factor, because as wind sweeps water away from the surface of leaves, other water molecules take their place. In most plants, roots continue to take up water at night but transpiration stops. This lets the plants replenish re·plen·ish

 water they lost during the day. When plants are under water stress, such as during a drought, the stomata begin to close as a defense against wilting wilting

dehydration of plants to the point where the leaves lose their turgor and hang limply. Can happen in living plants which later return to normal, or to cut plants before they are fed out. Thought to be a factor in increasing toxicity.
.

Transpiration helps to cool plants down, much as perspiring helps to cool people. When water escapes from the plants' leaves, it is heated by the sun and turned into vapor, a process known as evaporation. In the terrarium, water evaporates from leaves and also from the soil. On Earth, water evaporates from plants, trees, and bodies of water such as lakes, rivers, and oceans.

It is evaporation that lowers the temperature of plants, and people. A leaf in full sun at mid-day may have a temperature of 1 to 5 degrees Celsius warmer than the surrounding air. As the plant begins to transpire and evaporation begins, the temperature of the leaf drops.

Condensation occurs when water vapor cools and forms drops. In the terrarium, this condensation will be visible on the sides or top of the container. The drops crowd together and grow heavier. When they become heavier than the air, it "rains" in the terrarium.

The weather in a given environment depends partly on how many trees exist there. In a rain forest, the tree canopy traps water vapor, creating very humid conditions. In a desert, the lack of trees contributes to the dryness of the air and lack of rainfall.

In addition, some of the 8 colonists became sick from low oxygen and high carbon dioxide levels, requiring oxygen to be pumped in from the outside and air filters to be installed.

A shorter mission was begun in 1994, but the dome wasn't completely sealed and scientists were given a greater role. Today, Biosphere II operates as a research lab and education center run by Columbia University Columbia University, mainly in New York City; founded 1754 as King's College by grant of King George II; first college in New York City, fifth oldest in the United States; one of the eight Ivy League institutions.  for the 100 college students who come there to study each year. Even though the original goal of Biosphere II wasn't achieved, much has been learned by this ambitious experiment.

Planning and constructing simple terrariums, or more complex versions, is a wonderful experience for all of your students and a science project they can keep at home for a long time to come.

Level Pre-A

Main Concepts: Plants can grow together in terrariums. They are miniature gardens in sealed containers.

Picture Activity

Ask your students if they have plants growing in pots in their homes. Then ask if the terrarium pictured on the front page is different from a plant in a pot. The answer is yes, because the terrarium has more than one plant and the container is sealed. Ask what they see in the picture that shows what plants need to grow. Plants need soil and water. Why do they think WHY-FLY is wearing a raincoat. Explain that the lid traps water inside the terrarium for the plants to use.

Vocabulary

Answer: Terrarium. Ask them to point to the letters that are already filled in. Ask what letter it is and how many times it is used in this word. Tell them they can find this word throughout their Science Weekly. Have them use the letters given on the plant's leaves to help them finish spelling out this word.

Encourage your students to use their imaginations to invent a plant with a funny or unusual name and to draw a picture of it. For the Bonus activity, have them tape the plastic bag completely around the plant and put it in bright sunlight. They will see water vapor on the bag the next day. Explain that plants lose water through tiny holes in their leaves.

Puzzle

Answers: ACROSS--5) terrarium 6) rains 8) rocks DOWN--1) vapor 2) water 3) glass 4) soil 7) air.

DID YOU KNOW??

A small raindrop can take more than one hour to reach Earth.

Level E

Main Concepts: Terrariums are gardens growing in sealed containers. Water is recycled in a terrarium, just like Earth's rain cycle. Plants release moisture through tiny holes in their leaves, called stomata. In the Biosphere II project, people tried to live in a giant closed dome, like a terrarium.

Vocabulary

Answers: a = 2, i = 4. People lose water when they perspire and plants lose water when they transpire.

 will ensure a lighter soil so the roots will be able to spread out easily. Remind your students to leave space between the plants so that they will have room to grow. Have them use their hands to make small holes in the soil, then have them gently put their plants into the holes. They should pat the soil around the plants to hold them in place. Explain that the plants will "cook" if the terrarium is placed in direct sunlight. They should check the moisture level of their terrariums once a week.

Weekly Problem

Answers: The plants cost 35 cents each. The total, after tax, is $9.03. Make sure that your students calculate the cost of the plants before they add on the sales tax sales tax, levy on the sale of goods or services, generally calculated as a percentage of the selling price, and sometimes called a purchase tax. It is usually collected in the form of an extra charge by the retailer, who remits the tax to the government. .

Writing for Science

Explain that kudzu is a fast-growing vine that was brought over from Japan. It was planted in this country as a way to keep soil from washing away during storms. The problem is that kudzu grows so well, it takes over everything around it! Once it is planted, it can be almost impossible to get rid of. Kudzu can take over trees, buildings, and hillsides. Many people have tried to come up with creative ways to use kudzu. Encourage your students to use their imaginations in writing their scripts. What will the setting be? Will there be a hero? How will it end?

Challenge

Explain that plants lose a great deal (about 90%) of the water taken up through their roots through tiny holes in their leaves called stomata. Try to use 2 plants of a similar size, but one should have thin, grassy grass·y

). The other should have broad leaves (e.g. a Geranium geranium, common name for some members of the Geraniaceae, a family of herbs and small shrubs of temperate and subtropical regions. Their long, beak-shaped fruits give them the popular names crane's-bill (for species of the genus Geranium, ). Have your students check the moisture on the bags the next day. Regardless of the thickness of the leaf, the plant with the most total leaf surface will give off the most vapor.

Puzzle

Answers: ACROSS--4) pores 7) terrarium 8) rocks. DOWN--1) vapor 2) air 3) water 5) soil 6) stomata. Have your students look throughout their Science Weekly to help them.

Level F

Main Concepts: Terrariums are gardens in sealed containers. Early terrariums were used by traders and explorers to transport plants safely on ships. Water is recycled in a terrarium, just like Earth's rain cycle. In the Biosphere II project, people tried to live in a giant sealed dome, based on the concept of terrariums. This idea could be used to help build future colonies in places like outer space or underwater Underwater

. Also have them use their imaginations and think of what life would be like inside a sealed dome where nothing can leave or enter. What new responsibilities would this entail entail, in law, restriction of inheritance to a limited class of descendants for at least several generations. The object of entail is to preserve large estates in land from the disintegration that is caused by equal inheritance by all the heirs and by the ordinary ? What kinds of new experiences might they have with an entire miniature world right within walking distance?
