Big+Idea+K-2+Earth

The earth is constantly changing and operates in cycles.

 * Objects in the sky change their positions hourly, daily, and monthly. Many of those changes form repeating patterns.
 * The weather changes from day to day but there are general patterns to things such as temperature and rain or snow throughout the year.
 * Water carried in clouds sometimes falls to the ground as rain or snow.
 * Water falls on the ground as rain or melts from snow can seep into the ground or run off into streams and rivers.
 * The water we drink comes from wells in the ground or from ponds, lakes, streams or rivers.
 * Many things on earth change over time.
 * Animals and plants sometimes cause changes in their surroundings.
 * Rocks come in many sizes and shapes, from boulders to grains of sand and even smaller.
