Grade 8 Science Sample Test Materials - Helpful Hints for Using a Four-Function Calculator

Sep 25, 2026

Grade 8 Science sample test materials provide teachers and students with paper-based question types and response formats. The items and answer examples are designed to familiarize learners with how questions may look, while not representing the actual test length or serving as an indicator of student performance. The materials are not intended to guide classroom instruction. Included guidance covers using a four-function calculator and interpreting common display symbols. A periodic table reference is provided to support science questions.

Page 2 HELPFUL HINTS FOR USING A FOUR-FUNCTION CALCULATOR This is a picture of a generic 4-function calculator and its parts. GENERIC 4-FUNCTION CALCULATOR Equal Sign Decimal Point If you decide you need the calculator to help you answer a question, use the following information: 1. When starting a new problem, always clear your calculator by pressing the on/clear key. 2. If you see an E in the display, clear the error before you begin. 3. If you see an M in the display, clear the memory and the calculator before you begin. 4. If the number in the display is not one of the answer choices, check your work. 5. Remember, your calculator will NOT automatically perform the order of operations. 6. Calculators might display an incorrect answer if you press the keys too quickly. When working with calculators, use careful and deliberate keystrokes, and always remember to check your answer to make sure that it is reasonable. 7. The negative sign may appear either to the left or to the right of the number. 8. Always check your answer to make sure that you have completed all of the necessary steps.

FAQs

What is the purpose of the Grade 8 Science sample test materials?

The materials orient teachers and students to the types of paper-based Grade 8 Science questions and the response formats students may see on a test.

Do the sample items reflect the length or difficulty of the actual test?

No. The sample items and answers are not intended to demonstrate the length of the actual test, and student responses should not be used as an indicator of performance on the real test.

How should students use a four-function calculator when answering questions?

Clear the calculator at the start of a new problem, clear errors when an E appears, clear memory when an M appears, check that the display value matches answer choices, and be careful with key presses while verifying the reasonableness of results.
