K.10 - Earth and Space Systems: Changes

The student will investigate and understand that change occurs over time. Key ideas include

a)  natural and human-made things change over time;

  • describe things in nature that change over time. Bloom's Level:  Understand
  • describe human-made things that change over time.  Bloom's Level: Understand

b)  living and nonliving things change over time;

  • identify some changes that people experience over time Bloom's Level:  Understand
c)  changes can be observed and measured; and
  • use observations to describe the change of an object or living thing over timeBloom's Level:   Understand

d)  changes may be fast or slow.
  • classify examples as fast changes or slow changesBloom's Level:  Analyze

BIG IDEAS

Systems may exhibit stability and/or change depending on conditions.  These changes can be observed and measured.  Some of the changes happen quickly, while others may happen so slowly it is hard to see the changes.

UNDERSTANDING THE STANDARD

  • Change occurs over time.
  • Change can be fast or slow depending upon the object and conditions.
  • As people grow, they change.
  • Not all things change at a rate that can be observed easily.
  • Many changes can be measured.


ESSENTIALS

Essential Questions

  • Why is change important?
  • How can change be observed and measured?
  • How do humans change the world around us?

In order to meet this standard, it is expected that students will

  • identify some changes that people experience over time (e.g., height, weight, and color of hair).
  • predict how their own height will change over the school year. Measure and graph the information.
  • describe how people cause things to change (e.g., demolition of buildings, construction of buildings, cutting down trees, planting trees, and building highways).
  • describe how things change naturally. This includes seasonal changes, trees changing throughout the seasons, water in a stream washing away rocks and soil, rocks breaking off a mountain and animals and plants growing to include changes in height and weight..
  • identify examples of fast changes and slow changes. Slow changes should be the kinds of familiar changes that occur over weeks, months, or seasons. Faster changes include a weather event such as a blizzard or tornado, an earthquake or fire.
