Rain falls into the top of the gauge and collects at the bottom, where it can be easily measured. After a rain shower has finished, check to see how far up the scale the water has risen. Put your rain gauge outside where it can collect water when it starts raining.Congratulations, you have finished your rain gauge. Pour water into the bottle until it reaches the bottom strip on the scale.Use a ruler and marker pen to make a scale on the bottle.Turn the top upside down and tape it to the bottle. Place some stones in the bottom of the bottle.How much rain is really falling when you watch a heavy shower through the window of your home? How about on other days when it’s just a light shower? Find out by making your own rain gauge, recording the results and studying your findings. Modern microscopes have many lenses in them and allow us to see extremely small objects. It was later that the method of grinding glass to make lenses was perfected. The water droplet forms the shape of a convex lens, which refracts the light and converges it at the point where you see the image clearly. Pioneers of early microscopes originally used tiny glass globes filled with water to magnify objects, this is similar to what you are doing in this experiment. You may have to experiment to get the right distance but you should see a magnified image, especially if you have the drop as close to your eye as possible.Hold it close to your eye and look closely at an object such as a magazine.Dip it into some water to get a drop formed in the loop.Make a loop at the end of the fuse wire about 2mm wide.Objects to look at (newspaper or a magazine with fine print works well).Make a simple microscope using water and take a closer look at the world around you.The lens you create with water works like a microscope or magnifying glass, allowing you to see objects in much greater detail than if you were just looking with the naked eye.
