Unit Study - Changes on Planet Earth (/Online 2018 Edition)
by Kim A. Howe, M.S.
In this unit your child will recognize and observe change. He will explore causes of change, look at changes that occur in amount (numbers), and explore how graphs can display change. For the final project he will create a mobile that demonstrates a variety of changes in the environment.
This option provides online access to the Changes on Planet Earth curriculum as it was sold between 2011 and 2018. You will also need the required literature for this unit.
Note that this option is only for customers who need the earlier edition of the unit. A newer edition of the unit is also available.
