About This Quiz
Some people excelled at writing in school; others found that their time was better spent practicing their musical instrument of choice. Maybe going out for the football team was more your thing! If those options didn't pan out, perhaps you found solace in the scientific. Perhaps it was the vast depth of the universe that attracted some of your friends to astronomy. Biology promises an understanding of how life on our planet functions. Better yet is physics, which applies mathematics to daily happenings.
No matter what your favorite scientific subject was, if your memories of grade school bring back flashes of fetal pig dissections and chlorophyll, then this quiz is for you! The mitochondria might be the powerhouse of the cell, but will you be the powerhouse of this quiz? Are you able to distinguish between igneous, sedimentary and metamorphic rocks? Do you know what it means to be in homeostasis? Can you name the outer layer of skin that encases our bodies?
Take this quiz to test your scientific knowledge, and maybe learn a few things along the way. We'll go from A to Z, and then some, to determine if you're a top producer in this knowledge ecosystem or just a parasitic bottom-feeder.

The ability to float in a fluid is known as what?
Buoyancy is created when a fluid exerts a certain amount of force on an object that has been immersed in it. The idea is that because pressure increases with depth, there will always be an upward thrust on objects, since there is greater force at the bottom.
This is the layer of the Earth's stratosphere that blocks out the majority of the Sun's UV rays. What is it called?
Without the presence of the ozone layer, more of the sun's harmful UV-B rays would reach the Earth's surface. This would result in higher rates of cancer and an increased global temperature.
This type of energy is generated by heat beneath the Earth's surface. What is it called?
Geothermal energy is an excellent alternative for those looking for a sustainable and clean method to provide power. Heat from below the Earth's surface is used to create steam, which rotates a turbine, creating energy.
