Sample Essay Questions For Science and Math Students

Sample Essay Questions For Science and Math StudentsWhen I first began taking college courses in high school, my teachers had to ask me to write a sample essay to accompany some of the science and math tests we were required to take. A sample is not much different from a real test, but it is often easier to write an essay about something that you already know.Often the student's writing ability was their best test of their knowledge and understanding of the subject, and I remember wondering why they were trying to prove themselves when the tests already established their skill. I quickly learned that there was no easy way to show how much one was aware of the subject, but that a little practice could often make all the difference.In college, the sample essay questions have gotten a bit easier, and it is now usually possible to make the entire essay (or section) as easy as possible. There are a couple of different formats for samples. One is the Multiple Choice essay format, where a s tudent has to answer a series of three questions and answer them in the correct order.Another is the Check-List format, which means that students write about what they've learned and how they can apply it to solve a problem. In both cases, I find that a good teacher will be willing to let students do a little bit of reading and/or research first. The important thing is that they have an idea of the problem they are solving, and that they don't have too much information about it. As long as they know the facts and how they fit into the whole thing, they should be able to do a decent job.I find that there is a pretty big difference between the number of tests students take in a semester, and the number of science and math tests that they take throughout their college career. It is easier to earn an A in high school, but if the student can pass more than ten tests, then it may mean that the student isn't really learning very much in those tests.If you are concerned about doing too many or too few samples for a particular class, then just take some of the examples from that class and use the topics in the essay to help you cover the same ground as the sample. For example, if a student takes ten SAT subjects (Science, Math, English, and Writing), and they're going to write about five of those subjects, then they should be able to use the topics from the samples to expand on their topic knowledge. As long as they have the information to build on, then they should be able to show their proficiency.Using samples in your essays can help students see their knowledge in an organized manner. Also, if they have a sense of direction, they will have a greater likelihood of being able to finish the assignment on time.

[pic] This activity will focus on the visible portion of the electromagnetic spectrum. Background Information: About 300 years ago, Sir Isaac Newton saw a beam of sunlight through a glass prism. He discovered that light is made up of a spectrum of seven distinct visible colors. This spectrum of colors always appears in the same order. You can see this color spectrum (Red, Orange, Yellow, Green, Blue, Indigo, Violet and all the colors in between) when you look through a diffraction grating. There are two color ranges that are not visible to our eyes in this spectrum: below red is infra-red and above violet is ultra- violet. In a rainbow after a rainstorm this same color spectrum appears in the same order. Rainbows are created when sunlight passes through rain drops that act as millions of tiny prisms. The color of a solid object depends on the colors of light that it reflects. A red object looks red because it reflects red light and absorbs all other colors. A blue object looks blue because it reflects blue light and absorbs all other colors. A white object reflects all colors of light equally and appears white. A black object absorbs all colors and reflects no visible light and appears black. Just like when you color with too many colors in one area with crayons or markers, all colors are absorbed, none are reflected and it appears black! Explanation of visible light at the electronic level: What do fireworks, lasers, and neon signs have in common? In each case, we see the brilliant colors because the atoms and molecules are emitting energy in the form of visible light. The chemistry of an element strongly depends on the arrangement of the electrons. Electrons in an atom are normally found in the lowest energy level called the ground state. However, they can be "excited" to a higher energy level if given the right amount of energy, usually in the form of heat or electricity. Once the electron is excited to a higher energy level, it quickly loses the energy and "relaxes" back to a more stable, lower energy level. If the energy released is the same amount as the energy that makes up visible light, the element produces a color. The visible spectrum, showing the wavelengths corresponding to each color, is shown below: [pic] Note: [1 = 0.1 nm] Is light a particle or a wave? Is light composed of waves or of particles? If light is waves, then one can always reduce the amount of light by making the waves weaker, while if light is particles, there is a minimum amount of light you can have - a single ``particle'' of light. In 1905, Einstein found the answer: Light is both! In some situations it behaves like waves, while in others it behaves like particles. This may seem odd. How can light act like both a wave and a particle at the same time? Consider a duck-billed platypus. It has some duck-like properties and some beaver-like properties, but it is neither. Similarly, light has some wavelike properties and some particle like properties, but it is neither a pure wave nor a pure particle. [pic] A wave of light has a wavelength, defined as the distance from one crest of the wave to the next, and written using the symbol [pic]. The wavelengths of visible light are quite small: between 400 mm and 650 nm, where 1 nm = 10-9 m is a ``nanometer'' - one billionth of a meter. Red light has long wavelengths, while blue light has short wavelengths. A particle of light, known as a photon, has an energy E. The energy of a single photon of visible light is tiny, barely enough to disturb one atom; we use units of "electron-volts", abbreviated as eV, to measure the energy of photons. Photons of red light have low energies, while photons of blue light have high energies. The energy E of a photon is proportional to the wave frequency f, E = h f where the constant of proportionality h is the Planck's Constant, h = 6.626 x 10-34 J s. Also, the relationship between frequency and wavelength can be defined as: f = c ? where c is the speed of light (3108 metres per second). So photons still have a wavelength. A famous result of quantum mechanics is that the wavelength relates to the energy of the photon. The longer the wavelength, the smaller the energy. For instance, ultraviolet photons have shorter wavelengths than visible photons, and thus more energy. This is why they can give you sunburn,
