Changes to the land and sky occur all the time. Some changes are so gradual that we barely notice them, like the erosion of stones. Others are rapid, such as the felling of a tree. Some changes are minuscule, such as ants building a nest. Others are massive, such as the formation of mountains or development of thunderclouds. Some changes are very predictable, such as the time of the sunrise, and others we are still seeking to better predict, such as earthquakes. No matter how great or small, rapid or gradual, these changes impact our lives. Studying these changes helps us to predict and prepare for them. The Changes all around unit is an ideal way to link science with literacy in the classroom. Through hands-on activities students explore the natural, constructed and managed changes that they see in the sky and landscape around them.
