8^TH GRADE SCIENCE SEMESTER EXAM REVIEW

These are the things you should do to prepare for the exam.  Remember, this exam covers all of first semester.

A.  Gather all of your tests.  Be able to answer all of the test questions.  Cover the answers and see if you can answer them correctly.  Here is a list of the tests we’ve taken:

a.    Safety

b.    Chapter One – The Nature of Science

c.    Chapter Two - Technology

d.    Chapter Three – Motion, Acceleration, and Forces

e.    Chapter Four – Newton’s Laws

f.    Chapter Five/Six – Energy, Work, and Power

B.    You will be allowed to write notes on one side of a 3” x 5” index card to help with the exam.  This must be hand written.  It is always a good idea to write any formulas on the card.  The things that you need formulas for are converting between SI units (ex: cm to m); density; speed; acceleration; force, mass, and acceleration (Newton’s 2^nd Law); weight; momentum; kinetic energy; gravitational potential energy; energy of mass (Einstein’s equation); work; and power.  Bring this index card with you to the exam.

C.  Practice these questions from the book for review.  You may see these on the exam!

a.    Chapter One – p.32-33, #1-17, 18, 21, 22, 27-28.

b.    Chapter Two – p.62-63, #1-9, 11-12, 14, 16, 23, 26-27.

c.    Chapter Three – p. 92-93. #1-8, 10, 14, 23-26.

d.    Chapter Four – p.122-123, #1-14, 19, 23-27.

e.    Chapter Five – p. 148-149, #1-6, 8-11, 15-17, 22-25

f.    Chapter Six – p. 180-181, #6-7, 22, 26

D.  Other exam items.

a.    Be sure to bring a #2 pencil, your index card and a calculator to the exam.

b.    Bring all of your 1^st semester tests to turn in at the exam for extra credit!!

E. This is a list of the main topics that you need to know for the exam.  This is by no means a complete list of all of the information you should study.  This list is simply an overview – you still need to study the detail!
