Are You Smarter Than an 8th Grader?

Eighth grade is where math starts trading concrete numbers for letters, science starts digging into what's actually beneath your feet, and civics classes start explaining why the government is built the way it is. This quiz mixes all three, plus enough algebra to make sure you actually remember how to isolate a variable.

Pre-Algebra, Worked All the Way Through

Solving for x is really just a balancing act: whatever you do to one side of the equation, you have to do to the other. Take 2x + 5 = 17. Subtract 5 from both sides to get 2x = 12, then divide both sides by 2 to land on x = 6. The same logic applies whether you're isolating a variable or simplifying an expression like 3(x + 4), which distributes out to 3x + 12.

• Squaring a negative number always produces a positive result.
• Slope in the equation y = mx + b is simply the coefficient m.
• Order of operations still applies once letters get involved.

Rocks, Layers, and the Rules of Government

Earth science in eighth grade usually covers the planet's internal layers and the slow processes, like weathering, that reshape its surface over time. Civics classes cover the structural basics of American government: three branches, a Bill of Rights with ten amendments, and a Constitution that famously opens with the phrase We the People.
