K.8 One can make simple predictions in weather patterns. On a cloudy, warm day, it may rain. On a cloudy day that is very cold, it may snow. On a clear day there most likely will be no rain or snow. As animals and plants grow, they get larger according to a pattern. Natural objects such as leaves, seeds, and cones have patterns we can see. Home and school routines frequently follow a pattern. Kindergarten EARTH HAS PATTERNS. WEATHER CHANGES.

1.6 The sun is the source of light on Earth. The sun provides heat, which warms the land, air, and water on Earth. The rotation of Earth means that Earth turns once a day. The part of Earth facing the sun has daytime and the part not facing the sun has nighttime. Rotation of the Earth causes day and night 1 ST GRADE WHY WE HAVE DAY AND NIGHT.

2.7 Living things respond to weather and seasonal changes. This can be reflected in changes in growth and behavior. Adverse conditions of weather may slow the growth and animals (dormancy), whereas optimal weather conditions may accelerate the growth and development of plants and animals. Many trees produce new leaves in the spring and lose them development of plants and in the fall due to seasonal changes in temperature and light. The outward coloration and coloration patterns of many animals are similar in appearance to the plants in the places in which they live. This similarity to background is referred to as camouflage, and it enables animals to hide and avoid those that may eat or harm them. Some animals travel from one place to another and back again (migration) or go into a deep sleep (hibernation) due to seasonal changes. Some animals (geese, monarch butterflies) migrate. Some animals (bears, groundhogs) hibernate. Some animals undergo physical changes (thickening of dog fur in the winter and shedding in the summer) from season to season. 2 ND GRADE NATURAL EVENTS OF EACH SEASON.

3.8 The pattern of day and night is caused by the rotation of the Earth. One complete rotation occurs every 24 hours. The part of the Earth toward the sun has daylight while the part of the Earth away from the sun has night. The pattern of seasonal changes takes place because the Earth’s axis is tilted toward or away from the sun during its revolution around the sun. The Earth takes 365 days, or one year, to make one revolution. 3 RD GRADE EARTH MOVEMENTS. REASON FOR THE SEASONS. DIFFERENCE BETWEEN SEASONS, DAY/NIGHT, YEAR.

4.7 Due to its axial tilt, the Earth experiences seasons during its revolution around the sun 4 TH GRADE EARTH MOVEMENTS. REVIEW OF REASON FOR SEASONS. SEASONS AND WEATHER TYPES.
