1) Use the diagram below to answer the question.

Which is the title for the diagram?

2) Which determines the state of matter of a substance?

3) Which root system BEST helps a plant to survive in a dry environment with an underground water source?

4) What is the measure of the pull of gravity on an object?

5) Which natural process results in offspring that are genetically identical to one parent?

6) Why does an apple look red?

7) Use the tables below to answer the question.

Students perform an investigation using the swings on a playground. One of the students sits on swing 1. The swing is pulled as far as it could go and is released. The students count the number of swings in 60 seconds. The same student sits on swings 2 and 3, and repeats the procedure.

The students perform a second investigation, but this time with three different release points. The students want to find out if the release point affects the number of swings in 60 seconds. They conclude that the release point does not affect the number of swings in 60 seconds. What is the experimental design flaw in their second investigation?

8) Use the diagram below to answer the question.

What describes the event that occurred along line XY?

9) Which is NOT an example of a symbiotic relationship?

10) A reflector helps people in cars see a bicycle when it is dark. How do bicycle reflectors work?

11) A scientist tests the effectiveness of a medicine. The medicine is administered to 2,500 volunteers who discontinue all other treatments. What is wrong with this experimental design?

12) Which diagram shows the relative positions of Earth, the Moon and the Sun during a lunar eclipse?

13) What is the original source of the energy released when fossil fuels are burned?

14) Use the pictures below to answer the question.

What can be inferred from the bones in the pictures?

15) Use the pictures and table below to answer the question.

What does a warbler MOST likely eat?

16) Which is the most basic unit of matter?

17) What is the main function of an individual muscle cell?

18) A student flips a light switch but the light does not turn on. Based on this information, which inference is NOT valid?

19) Which list has all terrestrial planets?

20) What is Earth’s inner core made of?

EOC Science Test Content

The 8th Grade Science End-of-Course Test is a standardized assessment administered in several U.S. states to evaluate student knowledge in core science areas.

  • Physical Science (motion, forces, energy, matter)
  • Life Science (cells, genetics, ecosystems, evolution)
  • Earth and Space Science (weather, climate, solar system, Earth’s structure)
  • Scientific Inquiry and Investigation

The test is typically given near the end of the academic year and may be used as a part of the student’s final grade or to determine promotion to the next grade level.

Nature of Science Physical Science Life Science Earth and Space Science
  • Scientific method

  • Experiment design and variables

  • Data analysis and conclusions

  • Properties of matter

  • Forms of energy

  • Newton’s laws of motion

  • Simple machines

  • Cell structure and function

  • Photosynthesis and respiration

  • Heredity and Punnett squares

  • Food webs and biomes

  • Rock cycle

  • Plate tectonics

  • Weather vs. climate

  • The solar system and the universe

The Grade 8 Science EOC test doesn’t just test facts; it checks for deep understanding and the ability to apply scientific principles. It prepares students for high school science and strengthens critical thinking, data analysis, and problem-solving skills.
