Welcome to the Microscopic World What are all of these things for? Welcome to the hidden world of the microscope. Your new microscope is an instrument with lenses for making very small objects appear much larger so they can be studied. There are millions of tiny living plants and animals that can be easily seen with your microscope. a) Microscope – The microscope holds samples of very small things on clear slides.
Getting Acquainted with Your Microscope Learning About Your Microscope 1. Eyepiece – The eyepiece is where you look into the microscope. It is a small magnifying lens that collects the image projected up by the three objective lenses. Your microscope comes with two different eyepieces. The 10X eyepiece makes an image look 10 times larger. The 20X eyepiece makes an image look 20 times larger. 1. Eyepiece 2. Body Tube – This is the main tube of the microscope.
Microscope Safety Tips Getting Started Keep these safety tips in mind as you enjoy hours of fun projects and experiments with your microscope. 1) Insert two AA batteries into the base of the microscope, following the instructions on page 18. • Read all instructions before use. Follow them and keep them for future reference. • Keep small children and animals away from any experiments or projects. • When working with samples, keep your hands away from your mouth and eyes.
6) To change the magnifying strength, turn the rotating lens turret until you hear a click. 3. Pick up your sample with the tweezers and put it on the center section of the slide. Add one drop of water. If needed, you can now add a drop of dye. 4. Gently place a temporary slide cover over the sample, being careful not to allow any air bubbles in. 5. Remove any excess water or dye with a piece of paper towel by pressing it down gently over the slide cover. 6. Now you can observe your slide.
FAQs – Frequently Asked Questions PROJECT #1: Cloth Fibers 1) What can I see with my microscope? You will need: microscope scissors to cut small samples scrap pieces of cloth of different types clean, blank slides You can see thousands of things that are difficult or impossible to see with your eyes. You can see tiny plants and animals. You can observe plant and animal cells. You can see the differences between different plants, different papers, different fibers, and hairs from different people.
PROJECT #2: Animal Fur PROJECT #3: Leaves You will need: microscope 2 or more clean, blank slides samples of different types of fur and hair You will need: microscope 2 or more clean, blank slides different types of leaves An animal’s fur is similar to the hair on your head. Like your hair, it protects the skin underneath from cold, heat, and sunburn. Animals have different kinds of fur. Some animals have fine, smooth fur. Others have stiff, bristly fur. Some fur is short, and some fur is long.
PROJECT #4: Dirt and Sand PROJECT #5: Paper You will need: microscope several clean, blank slides several slide covers samples of dirt and sand from different places specimen vials to hold the samples pipette water You will need: microscope 2 clean, blank slides writing paper, tissue paper, newspaper paper towel pen water Dirt can have small pieces from rocks in it. It can also have lots of organic material. This is made up of decomposed plant and animal material.
PROJECT #6: Pond Water PROJECT #7: Friendly Bacteria You will need: microscope a pail or bucket an empty jar pipette clean, blank slides slide covers You will need: microscope clean, blank slides slide covers pipette yogurt (must say “active cultures” on the label) water petri dish Get a sample of water from a pond in a wooded area. It is best to get a sample in the late spring or summer. Dip your pail or bucket in the pond to fill it. Let it stand still for about a half-hour.
PROJECT #8: Crystals More Microscope Investigations You will need: Always keep your eyes open to find other ways to use your microscope. Here are two examples: microscope 2 clean, blank slides string a drinking glass very warm water (enough to almost fill the glass) a spoon (to measure and stir with) table salt sugar Take a piece of string about 3 inches (7.6 cm) long and tie it around the center of an old pencil. Now take a small drinking glass and almost fill it with hot water from the tap.
