Dear Parents,
We have completed science unit C, entitled Our Earth, and the above study guide will help your child study for the test, which will be Monday, January 11th. Students should fill in the blanks and answer the questions to help them prepare. The study guide does not need to be returned; however, students will need to study this material outside of class. We will review together in class before the test. Students will begin bringing science books home each afternoon to help them study. The books do need to be returned the next morning. As always, we will go through the test together as a class, but I will not offer help. Please have your child ask if he/she has any questions!
