to use a microscope correctly and perform wet mount slides accurately‚ thus becoming more familiar with the microscope. Hypothesis It would be hard to use the microscope without any kind of previous training and the parts of the microscope and their functions must be learned in order to use it properly. Materials & Methods Materials: 1. Filter paper 2. Tweezers 3. Pipettes 4. Cover glasses 5. Glass slides 6. The sample material (from the pond) Methods:

Objectives: To learn the parts of and how to use the microscope. To find specimens using low‚ medium‚ and high power. To make a wet mount slide. To view your own (or your partner’s) cheek cells under the microscope. To compare plant and animal cells. Procedure of Investigation 1. Add one drop of methylene blue to the middle of a clean slide. Be careful! Methylene blue will stain your clothes and skin. 2. Use the flat side of a toothpick to gently scratch the inside of your cheek. DO

SLIDE A slide show is a es of still images on a projection screen or electronic display device‚ typically in a prearranged sequence. Each image is usually displayed for at least a few seconds‚ and sometimes for several minutes‚ before it is replaced by the next image. The changes may be automatic and at regular intervals or they may be manually controlled by a presenter or the viewer. Slide shows originally consisted of a series of individual photographic slides projected onto a screen with a slide

be able to walk. It would be very hard to get around. You could consider blowing yourself around but it still wouldn’t work. Taking in a breath‚ you would slide forward and then blowing out‚ you would slide backward! Having no friction when walking could also be a huge advantage. You would be able to push yourself off against a wall and slide huge amounts of distances forever without being slowed down or even stopped by friction. A way to stop would be by just going into a wall! Buses‚ cars‚ trams

I then placed piece of onionskin onto the microscope slide‚ making sure there were no folds or creases‚ and put a drop of iodine onto the slide as well‚ to view through the microscope. On my first try the onion folded
