Science is a fun and powerful subject that can help answer questions about the world around you. It explains things like how the hole in the ozone layer was formed, the way the human body works, and who our evolutionary ancestors were. Science gives us a clear understanding of the universe and what exists in it. When new scientific discoveries are made, they open us up to new knowledge.
Has it been years since you learned about chemistry, physics, astronomy, or different kinds of animals? With these questions, you can see just how much you remember from the science classes you took back in 8th grade.
Put your science smarts under the microscope by taking this quiz. The questions in this test are taken from an actual test paper for 8th graders. How well will you do? See how well you will fare against an 8th grader by finishing this quiz!

The following diagram shows three wooden blocks, X, Y and Z, of the same base area but different heights. They are tilted slowly until the boxes fall in the direction as indicated by the arrows. The angles at which the tilted boxes topple over are marked as shown in the diagram. What can you conclude from the observations?
The greater the height of the wooden block, the bigger the angle at which it topples
The wooden block of shorter height will topple more easily
The greater the height of the wooden block, the smaller the angle at which it topples
The base area of the wooden block affects the angle at which it topples
