![]() ![]() When the sun is overhead, the light is falling straight on you, and so more light (and more heat) hit each square centimeter of the ground. In other words, the amount of light per square centimeter drops (the number of square centimeters increases, while the total amount of light stays the same). All the light is still in that ellipse, but the ellipse is spread out over more paper. Now slowly tilt the paper, so the circle elongates into an ellipse. All the light from the flashlight is in that circle. Shine the light from the flashlight straight onto the paper, so you see an illuminated circle. Why should this tilt of the Earth's axis matter to our weather? To understand this, take a piece of paper and a flashlight. This means that on this date, day and night have about the same length: 12 hours each, more or less. ![]() Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun. ![]() Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can. When the earth's axis points away, winter can be expected. When the earth's axis points towards the sun, it is summer for that hemisphere. The earth's spin axis is tilted with respect to its orbital plane. ![]() There are 5 tasks/activities for the passage, moving from easier tasks to more challenging activities.As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. This packet is both rigorous and Common-Core aligned. Questions have been carefully crafted to move readers from basic, recall questions to higher-level questions where students must cite evidence from the text to support their answers. I’ve taken all the guesswork out of differentiating and leveling of passages for you! One is in the fifth-sixth grade reading range, and the other is in the third-fourth grade reading level range. The informational passage included in this resource is provided in two differentiated reading levels. It includes interactive drag and drop annotation marks and fillable text dependent activities. The digital version of this Spring Equinox reading packet includes ready-made, visually-appealing Google slides for you to share with your class. This packet is perfect for celebrating this fun event, a mini science unit, or an informational reading unit! It has been a great hit with many teachers and reluctant readers. The Vernal (or Spring) Equinox takes place on March 20th.
