The Earliest Microscopes and Pond Ecology Essay

Although, Galileo did not invent the telescope, he is thought as the inventor of the telescope. Hans Lippershey was the person who invented the telescope in 1608. Galileo learned about the spyglass in 1609. He thought that learning about spyglass was so exciting and interesting. His interest of the spyglass led him to the discovery of improving the telescope. In order to discover deeper, Galileo began to experiment with making the telescope and polished the lenses of his own telescope to increase the range about eight to nine times further. Due to Galileo’s improvement of his telescope’s range, he was the first person to discover sunspots, to see the moon’s craters, and to keep on track of the phases of

Since Freshwater biomes are found all over the world, the types of plants and animals that live in these waters can be different. Some examples of plants that may inhabit a Freshwater biome are grass, spike rush, water lilies, cattail, and sometimes trees. Most plants living in these waters are not recognized by humans. Animals that live in these biomes are frogs, turtles, snakes, fish, and sometimes alligators. Insects like mosquitos also inhabit these biomes greatly. Animals such as raccoons and earthworms live on the land surrounding the biome, but depend on the biome to survive. Some animals, such as beavers, live in both the water and the land surrounding it. Algae also plays a big role in a Freshwater biome ecosystem.

2) Electron Microscope (EM) uses a beam of electrons to resolve electrons, better resolving powers than light microscope M:100,000x RP 0,2 nanometer

Another tool that have had a big impact in the science world is the Microscope. A microscope is an optical instrument that uses a lens or combination of lenses to produce a magnified image of small or microscopic objects such as bacteria and cells. One of the most known and historic purposes that the microscope has been used for is during the discovery of penicillin. Dr. Fleming, a bacteriologist, observed that a plate culture of staphylococcus had bee contaminated by a blue green mold. Then tracking and observing the bacteria through a microscope Dr. Fleming was able to observe that the colonies of bacteria next to the mold were being dissolved. Fleming then proceed to grow the mold in pure culture and produced a substance that killed a number of

The illuminating parts of a microscope enable us to see the detail of the subject placed under the microscope. The three main parts that enable us to do this are: the condenser which illuminates the object that is placed under the microscope, the objectives which forms the magnified image, and the eyepiece which enables us to see the magnified

cells. He shipped them across the world. Many great discoveries were made with these cells and

Throughout the fifteenth and sixteenth centuries, Europeans’ world view was affected by several scientific breakthroughs. This period of achievement is referred to as the Scientific Revolution. The Scientific Revolution was not a single event, rather a series of events with contributions from many people. Some of its main causes include individuals, the book written by Nicolaus Copernicus, and the loss of power by the Catholic church. During this period, scholars made lasting contributions that continue to affect the modern world.

Galileo(1564-1642) Made the telescope better and he used the telescope to observe planets, and he proves kepler’s theory, saw the imperfection of planets, and saw a storm on a planet also saw craters.

By using their microscopes, they found that every living plant and animal they examined was made of cells. As microscopes were improved, scientists were able to see smaller and smaller organisms. They found that no matter how large or small the organism was, it was made of cells, leading to cell theory. For example, a German biologist, Theodor Schwann discovered that all plant and animal cells were divided into cells by looking through his microscope. He also discovered that the cell is the basic unit of organization in organisms. Cells can be grouped together to form tissues, which can in turn be grouped together to make an organ. Organs can be grouped together to form a system, which is part of an organism. He was able to use microscopes to see the ways that cells work and help to determine which kind of microorganisms (bacteria) is causing the disease and making people ill. This is particularly valuable in the study of the components of organisms, where physicians are able to overcome a treatment of method to kill disease cells and restore people¡¦s health. The microscope revealed not only the cellular structure of human tissues, but also the organisms that cause diseases. The discovery of cells led scientists to study cells and discover more information about cells; this, allowed scientists to find ways to prevent or cure diseases. The use of microscopes has made many

Hooke published Micrographia, a book entailing observations made with microscopes and telescopes. Also in his work he was the first person

The use of the telescope led him to discover new characteristics of space and the solar system. He discovered Jupiter’s four largest moons and the rings of Saturn. He also discovered that the Milky Way galaxy is comprised of stars. The observation of mountains on the moon was made by Galileo as well. He also made numerous discoveries within these discoveries.

One thing that I would definitely suggest doing is planting grass seeds as well as other plants. This will help to produce more oxygen, give a more realistic environment to your animals, and take more carbon dioxide out of the air. Just in case your plants die, the grass can keep your biosphere alive for a little longer. If you can find any worms, you should put them in your biosphere because they help decompose dead organisms, and they produce carbon dioxide for the plants. I also recommend not having a pond, but using a spray bottle instead. Animals can drown in the pond, and it might even dry up if there isn't enough precipitation.

Procedure: First, set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide. Move the slide using the X and Y stage knobs until the specimen is within the view. Adjust the focus by looking into the eyepiece and focusing the specimen with the coarse then fine focus knobs. Adjust diaphragm until there is sufficient light

Cells, they are the building block of all life, they are what make up the entirety of living things on Earth and without them living things would cease to exist. It is because of this that cells are considered to be the most important known unit of life and are studied so often. Cells were first observed in the mid 17th century by English physicist and microscopist Robert Hooke using on of the earliest versions of the microscope. (Biologyreference.com, 2017) Hooke’s observations led to further investigations and studies into the topic of cells resulting in many major breakthroughs in the field of biology. Possibly the biggest of these breakthroughs is credited to have being made by Theodor schwann, Matthias Schleiden and Rudolph Virchow,

Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an image. An optical microscope cannot produce an image of an object smaller than the length of the light wave in use. To see anything smaller than 2,000 angstroms (about 1/250,000 of an inch) a wave of shorter length would
