Also, it is the part that we use to carry or lift it. 2. Base It’s the bottom of the scope. In addition, it houses the light source and the back section of base acts as a handle to carry the scope. 3. Course Focusing Knob We use it to adjust the position of objective lenses. Also, this should be done keeping in mind that the objective should not hit the slide. In addition, it should be stopped when the object is completely visible through the ocular. 4. Fine Focusing Knob We use it to bring the specimen in perfect focus once the specimen is visible through the course-focusing knob. Also, focus slowly to avoid contact between the objective and the specimen. 5. Illuminator It is the light source of the microscope. 6. Numerical Aperture or Objective lens It is found in a compound scope and is the lens that is closest to the specimen. 7. Ocular Lens This is the lens closest to the viewer in a compound light microscope. 8. Oil immersion Lens This is a 100x (100 times) objective lens. Also, this lens is small in order to attain high resolution and magnification. Furthermore, due to its size, it is important for the lens to get as much light as possible. Moreover, by immersion of lens in oil it eliminates the refraction of light, it happens because the glass and oil have almost the same refractive index. Most noteworthy, in this way the light is maximized and gives the clearest image. Besides, It oil immersion lens is used without oil then the produced Image will become unclear and has a poor resolution.Amazing Antarctica The Seventh Continent. Give a globe a spin. On it you can easily find six continents. Now look at the bottom of the globe. There you will find continent number seven: Antarctica. People did not find Antarctica until about two hundred years ago. Since then, we have learned a lot about this amazing place. Antarctica is the coldest continent. It is also the continent with the strongest winds. Less rain and snow fall in Antarctica than in any other continent. Freezing Antarctica Water covers most of Earth. Almost all of it is salt water. Most of the fresh water on Earth is frozen in the ice in Antarctica. Snow does not melt during the cold summers there. The ice builds up over many years. Life on and Around Antarctica The freezing weather in Antarctica makes it a dangerous place to live. Most plants and animals can be found near the coasts or in the sea. There are no trees, but there are other plants, such as moss. Penguins and seals are some of the larger animals in the icy waters of Antarctica. A Playground for Scientists People have taken steps to make sure that scientists can study in Antarctica. Many countries send scientists to study in Antarctica. Some work there all year, even during the cold winter. Others work only in summer. Many kinds of scientists come to Antarctica. They study animals, ice, and many other things. Many kinds of scientists come to Antarctica. They study animals, ice, and many other things. Thousands of visitors also come to learn about Antarctica each year. Conclusion. People do not know a lot about Antarctica. The cold, ice, wind, and rough seas make it a difficult place to visit. However, people around the world know how important it is to protect and study Antarctica.Farmhouse Four-bedroom farmhouse in the countryside. All of the four double bedrooms are en suite with luxury shower and bath. Farm kitchen with barbecue, tables and chairs outside. Great for groups of friends. The supermarket is half an hour by car and you can take a train from the village into the city. Escape from normal life for a few days as we have … NO INTERNET and you can only use mobile phones at the bottom of the garden!Camshaft: A rotating shaft in an engine that controls the opening and closing of the intake and exhaust valves. Aftercooler (air to air): A device that cools the compressed air from a turbocharger using outside air. Glow Plugs: Heating elements used to aid in starting diesel engines in cold temperatures. Timing Cover: The cover that protects the timing gears and belt or chain in an engine. Exhaust Manifold: A component that collects exhaust gases from multiple cylinders and directs them to the exhaust pipe. Oil Suction Tube: A tube that draws oil from the oil pan to the oil pump. Air Compressor: A device that increases the pressure of air and is often used to power air brakes or pneumatic tools. Oil Cooler: A device that cools the engine oil, helping prevent it from overheating. Supercharger/Blower: A device that increases the pressure of the air-fuel mixture entering the engine to boost power. Piston Rings: Rings around the piston that seal the combustion chamber, control oil consumption, and conduct heat. Crankshaft: A shaft that converts the linear motion of the pistons into rotational motion to power the vehicle. Oil Pan: A reservoir at the bottom of the engine that collects and holds the engine oil. Connecting Rod: Connects the piston to the crankshaft, converting the piston's motion into rotational motion.

BDC (Bottom Dead Center): The lowest position the piston reaches in its stroke. 4 Cycle: A type of engine that completes a power cycle in four strokes (intake, compression, power, exhaust). Articulated Piston: A piston with two pieces (crown and skirt) joined by a pivot, allowing some flexibility in movement.Create a multiple choice quiz with the following information: Earth’s Sphere Everything on Earth can be placed into one of four major subsystems: land, water, living things, and air. These four subsystems are called "spheres." Specifically, they are the "geosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Geosphere All the rock, soil and sediments that makeup Earth’s land. It comes from the word “Geo” which means “Earth.” Hydrosphere All the oceans, rivers, lakes and water on Earth. It comes from the word “Hydro” which means “water.” Atmosphere All the gasses surrounding the earth. It comes from the word “Atmos” which means “air.” Biosphere All the living things on Earth. It comes from the word “Bio” which means “life.” Interact act in such a way as to have an effect on another; Freshwater naturally occurring water that is not salty, and is suitable for consumption if clean or processed. Groundwater water held underground in the soil or in pores and crevices in rock Recycling To reuse something that would have otherwise been thrown out or to turn it into something usable again instead of sending it to a landfill. Erosion After pieces of the earth are broken down through weathering, those pieces are moved through Erosion. Erosion is the process of moving things from one place to another. Mushroom Rocks Naturally occurring rocks that look like a mushroom. They can be formed when sand gets carried by wind and hits the rock. This weathers the bottom of the rock more than the top. Dry Ice A solid form of carbon dioxide that is very cold and turns directly from a solid to a gas.
