Change on the earth happens over different amounts of time. Some change happens over a short amount of time for the earth, such as 100 years. Other change might take thousands of years. And still other changes take millions of years.
Go to these two sites to review how to read big and little numbers according to place values: 1s, 10s, 100s, 1000s, 10,000 and 1,000,000:
After you have reviewed place values, you should do the place value activity on the Shape It Up student sheet.
Now you will get to engage in an online interactive activity to experience how mountains, rivers, and canyons were formed. Start by going to Shape It Up!.
Before clicking on the "Start" button, go to "How to Play" to review what to do during the activity. You can also go to "Learn More" to get more information about volcanoes, water, glaciers, and wind, the four geologic processes of change that you will encounter during the activity.
The objective of this activity is to choose the geologic process that could change one landscape feature, like a prairie, into another type of feature, like a canyon. Once you have chosen the process, you'll be asked to indicate how long it takes for the change to occur.
This esheet is a part of the Shape It Up lesson.
