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.

x10 objective lens. You rotate the nosepiece around to x40 but the specimen is not visible. Describe what you should do next? Start by using the fine adjustment to attempt to focus on the Euglena. However‚ if it is still not visible‚ return to the x10 objective lens and use the fine adjustment to ensure the Euglena is as sharply focused as possible. Then‚ use the stage control to re-position the slide so the Euglena is directly in the centre of the lens. Return to the x40 objective lens‚ and the Euglena

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).

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

shape and position of the two lenses in a compound light microscope. Light passes through the convex lens and is bent. The light continues on to the next lens and are bent again. The initial pass through the lens caused the light to intersect but the secondary pass of light through the second lens causes them to be parallel. The light from the top of the image is now seen in the second lens at the bottom and it will appear inverted. The color of the threads are cream color‚ red and blue. They
