This week in Sci


This week we went deeper in to the Ideas of solstices and equinoxes.We learned and experimented that the earth is at constant tilt of 23.5 degrees.That shows that the equinoxes have equal time of 12 hours of day and night. the days and nights are uneven during solstices . The earth is also closer to the sun during equinoxes and farther away during solstices. That leaves one conclusion the earths tilt is the only reason we have seasons.
