About This Quiz

Looking for a challenge? Don't be surprised if it comes in the form of an elementary school student testing his or her knowledge of the sciences against yours. C'mon, we know it's been awhile since someone asked you about mammals, reptiles and amphibians. Or when was the last time you checked your knowledge on fusion versus fission? That's why this quiz is perfect for you. You can test your scientific smarts before confronting mini-geniuses with a smirk on their face. 

In this quiz you'll be asked questions about atoms, molecules, elements and compounds, as well as how plants make food from the sun. Not sweating yet? How will you do on questions about gravity and the fourth state of matter? Now it's looking like a real challenge. Either way, if you're a science fan, you'll be pleasantly surprised at what elementary school students are required to know in the US school system. And remember, with all the new scientific breakthroughs we've had over the years, it means students have to know even more than you did back then. So put on your thinking cap and take the quiz now. We'll save the dunce cap and a seat in the corner for those who don't get a high score.
