https://padlet.com/tlp042/gbclvnys9nvqohtl This phenomenon can be used in elementary to explain darkness and illumination. Even though light travels between the Sun and the Earth, space appears black because there is nothing (e.g. gas, dust, etc.) for the light to reflect off of. This can also be used as a much deeper phenomenon. Since space is filled with billions and billions of stars and each of them give off light why isn't space completely light? The answer lies in the expansion of the Universe. en-us 2022-01-13 18:12:13 UTC 2026-02-25 23:01:07 UTC hello@padlet.com tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990963345 2022-01-13 18:18:16 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990963345 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990970007 2022-01-13 18:21:39 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990970007 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990984517 2022-01-13 18:29:15 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990984517 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990989552 2022-01-13 18:31:46 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990989552 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990994976 2022-01-13 18:34:30 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1990994976 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1991072944 This Phenomena applies to Louisiana because space is visible when looking up at the sky and is dark at night. ]]> 2022-01-13 19:15:05 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1991072944 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996859101 2022-01-18 01:59:39 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996859101 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996860819 2022-01-18 02:01:10 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996860819 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996862802 This phenomena is applicable to all grade levels and would be interesting to students in 1st grade all the way up to seniors in high school. Maybe even college students! I know I found it very interesting!]]> 2022-01-18 02:02:52 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996862802 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996867667 This phenomena is unique because when we are looking toward the sun we see a bright white light and while looking away, we would see only the darkness of empty space. Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.]]> 2022-01-18 02:07:27 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996867667 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996883838 At night, when part of the Earth is facing away from the sun, space looks black because there is no nearby bright source of light. Even though space has so many stars, that does not mean that all those stars give off enough light to brighten up space. In fact, when a source of light is moving away from you (like a star is), the wavelength of that light is made longer and it makes the light appear on the red spectrum instead of white. This means that the light from the stars moving away from us will shift more towards red, or become invisible altogether. ]]> 2022-01-18 02:22:01 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996883838 tlp042 https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996892707 2022-01-18 02:30:13 UTC https://padlet.com/tlp042/gbclvnys9nvqohtl/wish/1996892707
