PRACTICE Test: Earth Science
INSTRUCTIONS
1. Please write your first name and your last name on the top of this page.
2. Please use the Periodic Table that is provided with this test.
3. Please use your brain and only your brain.
a. You may not “borrow” your classmates’ brains – any and all cheating will result in a
zero.
b. You may not use your notes nor your textbook.
4. Please double check all your answers!
5. Please respect each other’s right to concentrate. This means absolutely no talking at any point
– talking may result in a zero.
6. If you finish early please hand in your test and begin to work on the assignment given on the
overhead. You will have a quiz on this assignment tomorrow.
THANK YOU AND GOOD LUCK!
