viewing the onion cell through the microscope. Place the microscope slide onto the microscope stage. Place the microscope stage clips onto the slide. This will prevent the microscope slide from moving during observation. Ensure that the microscope’s lens magnification is at either x10 or x40. Look through the eye-piece and draw what you can see. Post-Practical - After the Experiment/Tidying away equipment; Turn the focusing handle so that the microscope lenses are at the top of the microscope.

capable of bending when passing through an object‚ when it enters the lens‚ the light gets reversed and magnified through the prisms‚ and eventually enters your eyes. Our eyes are also binocular instruments. This means they take to images and bring them together to form a single‚ high quality image. Binoculars consist of two small telescopes mounted side by side‚ one for each eye‚ and a focusing mechanism. By having a lens system for each eye‚ these instruments provide three-dimensional viewing

Lori Stenbeck Bio K121 June 7‚ 2012 The Microscope Introduction: The purpose of a microscope is to see either enlarge images of small objects and or make seen what is invisible to the naked eye. We have two types of microscopes available in the lab. The dissecting microscope is designed to study objects in three dimensions at low magnification. The compound microscope is used for examining small or thinly sliced sections of objects under magnification that is higher than the dissecting microscope

The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for

Ensuring children and young people’s safety and welfare in the work setting is an essential part of safeguarding. While children are at school‚ practitioners act in ‘loco parentis’ while their parents are away. As part of their legal and professional obligations‚ practitioners hold positions of trust and a duty of care to the children in their school‚ and therefore should always act in their best interests and ensure their safety – the welfare of the child is paramount (Children Act 1989). The Children

Notes for WK2 – 10 September Lesson 1 * State the resolution and magnification that can be achieved by an electron microscope. * explain the need for staining samples for use in electron microscopy Lesson 2 * calculate linear magnification of an image such as photomicrograph or electron micrograph Key words * Resolution= the ability to distinguish 2 separate points as distinct from each other. * Magnification= the number of times greater an image is than the actual object

There are three main designs of telescopes; refractors‚ reflectors‚ and a catadioptric. The refracting telescope is one of the most common telescopes. The refractor telescope captures an image through the lens and bends it. After it is bent‚ it is sent to the focal point and modified by the lens and viewed through the eye piece‚ (Telescopes‚ 2013). The refracting telescope is among one the most popular telescopes because the strengths of the telescope. This type of telescope is long lasting‚ useful
