We kept them under a window in the kitchen, where they thrived, and, in spite of precautions, made occasional sorties into the kitchen.

The family took these in their stride, but we sometimes had nervous visitors who watched the caterpillars eat, and grow, and shed their skins; eat, and grow, and shed some more.

One got small, elliptical, white "seeds" on his coat, and we knew be had been destroyed by ichneumon fly larvae, of which these were the cocoons.

We dropped him, and his murderous guests, into the kitchen stove so that they would not emerge to lay eggs under the skin of others.

The grubs hatch and eat their host, then break through the skin to make cocoons on his back.

One by one the caterpillars left the lilac leaves and walked around and around the "crawly" house.

One of them got out and escaped completely, turning up months later on the windowsill, a newly emerged Edwards' glasswing.

I am still wondering where he made his chrysalis.

The others marched around and around the aquarium.

We put in dead twigs for them to climb and hang on, we gave them a dark box to hide in, but still they crawled around and around for days.

They did not look happy.

One or two gave and died, finally dug into the dirt, where they made hard, brown chrysalides.

The moths particularly intrigued me.

There were so many of them and yet we saw so few.

Not many of them flew in the daytime.

A few we caught among the flowers with the butterflies-the dark blue Ctenucha with white bands and red spots, and the creamy and gray boll moths around the wild radish blooms We had no luck with baiting, smearing molasses and beer on tree trunks, so I tried attracting the night ones by leaving my bedroom window open while I read with the light on.

Mosquitoes came in, and bats; also moths, including a few fragile green ones and a lot of small brown ones with pearly, iridescent underwings.

But Chuck said it disturbed his sleep to have me leaping around the bedroom with a butterfly net.

Altogether we caught and mounted about seventy kinds of moths, but we were able to identify less than that.

We are waiting for someone who knows about them to come and help us.

We are making a life history frame of the Samia rubra.

We have the little eggs with neat round holes in them where the babies crawled out.

- Instruct students, in groups of two or three, to create a map from a sheet of butcher or white mural paper. Have students include a legend designating specific symbols for various landforms. The map may be an interpretation of a state, a country or a continent, depending on academic level. Younger students may benefit from creatively mapping landforms using teacher-devised symbols, such as a triangle for a mountain, a square representing a plateau, a blue circle for bodies of water and brown dots for desert regions.

- Using a prepared rice krispie mixture, students can form a plateau (which is similar to a mountain with the tip cut off, revealing a flat surface toward the top) with their hands. Cover the puffed rice plateau with moldable chocolate or a thick layer of chocolate frosting. Cut plants and trees to adorn the edible landform from lime-flavored, green fruit candies; strategically place them on the chocolate before it hardens, or stick to the frosting. Share the treat among classmates after the landform presentation.

- Prepare a blue raspberry gelatin mixture in a round mixing bowl and refrigerate until almost firm. Set a semicircle of a melon or an enlarged sugar cookie in the center and refrigerate again until completely firm. The melon rind or the cookie will appear as an island. Decorate the island with frosting or fondant molded palm trees. If using a cookie, sprinkle cinnamon and sugar over the treat to appear as sand on the island.

- Instruct students to prepare a diorama on a specific landform, such as a desert. Use play sand or crushed graham cracker crumbs to line the bottom of a shoe box. Insert plastic toy palm trees and cacti. Add other animal life typical of desert regions, such as camels, by creating them from paper or finding plastic toys from a dollar or discount store. Adapt the diorama to any landform.

Majority of the people prefer this profession as their career as it one of the best ones these days. Before choosing this field one must satisfy the necessities to the exam conducted by the board of nursing. Degree form a licensed university is necessary for choosing this particular field. If all these things are permitted by the university then one has to write the NCLEX test. If one has qualified in this test then they can avail the chance for picking the university they favor.

For becoming a registered nurse one can choose two different courses. One is the Bachelor degree of nursing (BSN) which is a four year course and whereas the other one is the Associated degree of nursing (ADN). One can select the course they like and in this period one must work in the clinical hours and these are also measured.

If one has qualified in all these things then they can get a RN license. The RN license is being issued after the successful completion of the degree. Once the license is being issued the person is a registered nurse and they can apply for a job in government sectors, hospitals etc.

For a period of 1-2 years the license for the RN is being issued. After the completion of this period one must renew them in order to carry on with their job. Sometimes the license is being given for several hours and they are paid on hourly basis. After the conclusion of these hours one can renew their license once again.

Registered nurses also earn a good income annually. The salaries for them depend upon their specialization of the course, years of experience, qualification and location. The Bureau of Labor statistics have given a report on their salaries recently. The report stated that the nurses are earning a good income in comparison with the various professions.

An average nurse earns $63,750 annually which is a huge amount. On hourly basis they earn about $31 and these may increase based on the location and experience. At the start of the career one can receive $30,000-$50,000 annually and per hour they receive $26. If one works in the hospital which has nation wide recognition, they can achieve the high amount of salaries which they never dreamt off.

As a result of these things most of the people prefer this profession. Once if you have established in this job there are chances for attaining the top position such as management which is a huge benefit.

- When deciding between a traditional four-year college or university and a trade school, one of the biggest deciding factors will be what type of work you want to do in your future career. Some career paths make it easy for you to decide. For example, future teachers need to attend a four-year school, but future mechanics would learn their skills better at a trade school. Other options though, are less obvious. Talk to professionals in your field, particularly those who are in charge of hiring for the types of companies or organizations where you would like to work. You can find out what types of candidates hiring managers prefer to hire and what they would suggest for you to do in hindsight of their own decisions.

- Four-year schools and vocational schools offer very different certifications to students upon graduation. At a four-year school, you'll earn a bachelor's degree, but at a vocational school, you'll receive a specialized certificate in your new area of expertise. For example, if you want to be a technical writer, you could get a bachelor's degree in English, or you could earn a technical writing certificate. The degree offers a broader education with greater job versatility if you change your mind about your work in the future, but you may find it easier to land a technical writing job straight out of school with a specialized certificate.

- Think about the way you learn best and what type of learning environment you prefer. As a rule of thumb, four-year schools offer more of a lecture, visual, academic learning environment and vocational schools offer a hands-on approach. Vocational schools are also more likely to reflect your future workplace to get you well-accustomed to the job you'll be doing. Keep in mind that this isn't always the case, and you should look into the specific schools you're considering to find out for sure.

- Assess your time and financial resources to help figure out which type of further education is best for you. The main resources you'll need to complete your education are money and time. A traditional college or university can take anywhere from three to five years to earn a Bachelor's degree, while a vocational school usually takes one to two years. Look up semester or year-long tuition costs, since these vary greatly among both four-year and vocational schools. As a rule of thumb, the less time (fewer semesters) you spend in school, the less you'll have to pay in tuition. If you want to attend a four-year university but don't have the cash to pay the bill up front, look into available scholarships, grants and loans.

- A student should know the topic assigned by the teacher and have some idea about the topic and have basic understanding about the topic.
- If the topic is broad in aspect you should narrow it down to some specific point.
- Select some important points regarding the topics and make its outline.
- Then start writing the college paper with the introduction part. Introduction should carry the overview about the topic.
- The body of the paper should have a hypothesis statement included.
- Then the discussion on the hypothesis is done and information collected from different resources should be mentioned.
- Then comes the conclusion part. The college term paper should have a healthy conclusion which can remain as a mark on the readers mind
- Reference part should be included. It is an important part of the college term paper because through these references the teacher may know that one has gone through the resources and information is correct.

They are so closely related to us that everything we do from reading signs on the road to identifying a flower has a bit of colour involved in it.

This association is such that they even have an effect on our mood as well for instance, gray is depressing - green is prosperous.

Colour Perception We recognize colours with the sensors in the retina of our eyes.

These colour perception sensors are made of rods and cones.

The rods are receptive to low intensity of light and, therefore, are not sensitive to colour.

They perceive images as black and white.

There are about 120 million rods in the human eye.

The cones on the other hand require a greater intensity of light.

With about 7 million in number, each cone contains one of the three pigments sensitive to red, green or blue.

These pigments have the capacity to absorb only a particular wavelength of colour.

While short wavelength cones are able to absorb blue light, middle and long wavelength ones absorb green and red light.

When a combination of cones gets pressed into action, we see a colour that has a wavelength between the primary colours.

Visible light ranges between 380 to 780 nm on the electromagnetic spectrum.

This is between the wavelength of the ultraviolet and the infrared light.

A light comprising of equal proportions of all the visible wavelengths either gets absorbed or reflected.

It is this reflected light that gives an object its perceived colour.

The temperature of the light source also determines an object's perceived colour.

Fluorescent lamp or a camera emits white light as it corresponds to a temperature of around 6000 Kelvin and does not distort colours.

Lights bulbs, on the other hand, correspond to a temperature of around 3000 Kelvin and cause objects to appear yellow.

People who have less number of particular cones suffer from colour blindness.

It is a state where people are unable to perceive differences between colours.

If a person is suffering from this colour perception disease, it is most likely to be genetic, which means it is in the genes.

This may, however, also occur because of eye, nerve or brain damage.

Colour blindness application is designed to simulate various types of human partial colour vision.

They can show the brightness information in normal colour vision and what each kind of cone sees.

The applications have built-in algorithms to detect the severity of the blindness.

The science or the study of colour is referred to as the Chromatics.

It signifies the basic concepts of primary colours and hues, principles regarding their saturation and brightness, web-safe colours.

The study distinctively focuses upon the understanding of different colour concepts.

In case of colour blindness, all these instincts and stimulations are highly affected; as a result the patient feels difficulty in recognizing them appropriately.

It can be safely concluded from the above that colour perception is not in eye of the beholder, it's rather in the brain.

Different types of fraction rules:

Fraction rule for addition

Fraction rule for subtraction

Fraction rule for multiplying

Fraction rule for division

Fraction rules:

Multiplication:

Fraction rule for multiplying fractions multiply both numerators and denominators.

1 3 1 x 3 3

---- x ----- = ---------- = ------

2 5 2 X 5 10

Addition:

Fraction rule for addition - Same denominators just add the numerators. Keep the same denominator.

1 2 1 + 2 3

----- + ----- = --------- = -----

8 8 8 8

Fraction rule of addition with different denominators, Then take L.C.M of those two numbers as the denominator and multiply the numerator with a suitable number to give the L.C.M value. And then add

1 1 2 1 3

----- + ----- = ----- + ----- = ------

2 4 4 4 4

If the denominators don't divide equally, Then take L.C.M of those two numbers as the denominator and multiply the numerator with a suitable number to give the L.C.M value. And then add

Note: Since 3 doesn't go into 5, use 3 x 5 = 15.

1 3 5 9 14

----- + ----- = ----- + ----- = -----

3 5 15 15 15

Subtraction:

Fraction rule of subtraction with different denominators, Then take L.C.M of those two numbers as the denominator and multiply the numerator with a suitable number to give the L.C.M value, and then subtract

1 1 2 1 1

----- - ----- = ----- - ----- = -----

2 4 4 4 4

Mixed Numbers:

Changing mixed numbers to improper fractions Find the number of unit fractions in the whole number, and then add the fractional part of the mixed number.

2 6 2 8

2 ---- = ----- + ----- = -----

3 3 3 3

Changing improper fractions to mixed numbers divide the numerator by the denominator to get the whole number. Then the fraction is the remainder over the denominator.

8 2

For ----- = 2 with a remainder of 2 so the mixed number is 2 ----

3 3

Division:

Fraction rule for dividing fractions to divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

3/4 3 8 24

------ = ----- x ------ = ------ = 6

1/8 4 1 4

A fraction is a number that can represent part of a whole. For example '(5)/(2)' is a fraction. What does 2 stand for? It is the number of equal parts into which the whole has been divided. What does 5 stand for? It is the number of equal parts which have been

taken out. Here 5 is called the numerator and 2 is called the denominator.

Types of fractions:

proper fraction the numerator is less than the denominator (e.g.7/9).

improper fraction the numerator is greater than or equal to the denominator (e.g. 9/7).

mixed fraction is the combination of a whole number and a proper fraction.(e.g. 23/4).

equivalent fractions have the same value.

e.g ,1/3 ,2/6 and 100/300 are all equivalent fractions.

Complex fraction has the numerator or denominator or both contains a fraction.]]>
