![]() ![]() Is this look-alike so close both species ought to be avoided, just in case? Is this other species an edible that makes some people sick, or a poisonous species that some can eat safely? It’s hard to know where to draw the line. As a result, the list of edible mushrooms varies a bit, depending on whom you ask. Then there is the issue of poisonous look-alikes, another difficult subject, given that what looks alike to a beginner might look very different to an experienced collector. If you don't see any change in color, add a couple more drops of milk to the mixture and try again.In Florida, as elsewhere, “edible mushroom” is something of a moving target in that there are a lot of species that can be safely eaten by some people sometimes, while making other people-or even the same people-sick at other times.What color is the light coming from the flashlight? What color is the light as it travels through the glass? What color is the light on the far side of the glass? Shine a flashlight at the top of the glass of water.(If you are using a soda bottle, you will need to use more milk, cap the bottle, and shake gently.) Fill the straw with about an inch of milk, add it to the glass of water, and mix with the straw.What color is the light coming from the flashlight? What color is the light as it travels through the glass? (You might want to put a sheet of white paper on the far side of the glass to help you see the color.) Shine the light through the glass of water.Darken the room by closing the shades and turning off the lights.A few drops of milk (whole milk works best).Tall clear drinking glass or clear soda bottle.It also makes sunsets more colorful and red. This scattering of sunlight can make the sky look hazy. When there are lots of aerosols in the atmosphere, even more sunlight is scattered and absorbed. That’s why the setting Sun often looks red! This causes the light to scatter, and we see shades of red, orange, or yellow, which are the longer wavelengths of light. Light has to travel through more atmosphere than it does when it’s overhead. Gardiner (center) Sunset Sky Colorsĭuring sunrise and sunset, the Sun is low in the sky. When there are little particles in the air called aerosols, the sky is a lighter blue. ![]() The sky isn't always the same color blue. When there are lots of aerosols, the sky might even look white in the middle of the day, even if there are no clouds. When there are more aerosols in the air, the sky is a more pale blue color. When there are few aerosols in the air, the sky appears clear and deep blue during the day. Others are formed when people burn fossil fuels or wood. Some aerosols form naturally from sea salt and volcanic eruptions. Aerosols are tiny particles and liquid droplets in the air. That's because of aerosols in the atmosphere. Sometimes you'll notice that it's a lighter blue, and other times it's a darker blue. (If our eyes were better able to see violet light, then the sky would look violet in color.)īut the sky isn't the same color blue every day. The sky looks blue because we see the scattered blue light. Shorter waves of light, like violet and blue, are the most likely to be scattered by air molecules. ![]() Light from the Sun is scattered in all directions by molecules of air as well as particles like aerosols and dust. When light is moving through the atmosphere, some of the waves are scattered, which gives the sky its color. Colors like blue, indigo, and violet travel in shorter waves and have more energy. Colors like red, orange, and yellow travel in longer waves and have less energy. The light travels in waves that are too small and fast for us to see. Sunlight, or visible light, is made of all the rainbow colors: red, orange, yellow, green, blue, indigo, and violet. ![]()
