Ever since the Big Bang, the Universe has been drifting and expanding. The birth and death of stars leave an aftermath of galaxies, planets, and even living organisms. The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly.
Go on the hunt for Pluto, see a quiet meteor shower, or go on the hunt for
the Big Dipper this week.

If we see at the sky for some time at night, then we will observe some stars forming groups with shapes. So, the shape formed by the group of stars is called a constellation diagram. The shapes of constellations resemble objects familiar to those people. Each constellation is signified by an animal, a human being, or some other objects it appears to resemble. All the constellations seem to move in the sky from east to west. This is due to the rotation of the earth on its axis from west to east.

A lesson written to allow student choice - or require indoor written participation. May be modified by the teacher with correct date, etc. Several slides refer to actual students- this allows the lesson to serve as an example. Several questions do not have answers yet. This allows the teacher to assign the presentation, requiring students to find the answers themselves.
a draft of a chemistry lesson on the 6- sided crystal structure of snowflakes, as related to water molecule structure and hydrogen bonding. Note that water VAPOR condenses directly into ice crystal snowflakes, with no liquid phase between the vapor and solid phases.
