It’s been a minute (or a few decades) since you’ve built a papier-mâché volcano or looked at microscope slides, but in honor of back-to-school season it’s officially time to get back into the learning spirit. We’re revisiting our student days with a series of grade school quizzes, and next up on the list is — drum roll please — science.
Think you remember everything from those solar system and biology lessons? Answer the questions below to see how you’d fare against 10- and 11-year-olds. And don’t forget to try your hand at this eighth grade spelling test — it’s harder than you think!
The order of the planets from the sun is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
The five kingdoms of life are: monera (prokaryote), protista (eukaryote), fungi, plantae, and animalia.
ANSWER: from other rocks
While magma or lava solidifies into igneous rocks, metamorphic rocks come from preexisting rocks transformed by heat, pressure, or chemically reactive waters.
ANSWER: upper mantle
The basic layers of the Earth are: the crust, upper mantle, lower mantle, outer core, and inner core.
About 78% of the atmosphere is nitrogen. There are also small amounts of argon, carbon dioxide, other gases, and water vapor.
Deciduous trees (like oaks) drop their leaves in the fall, a process called abscission. Coniferous trees keep their foliage and include pines, cypresses, firs, redwoods, spruces, and cedars.
ANSWER: the weathering of continents
The erosion from rainfall causes ions like sodium and chloride (which together make salt) to flow into the oceans, where they accumulate.
Estivation is when animals go dormant in response to high temperatures and dry conditions, often in the summer. Hibernation occurs mostly in the winter months.
Physical changes — like evaporation — don’t change what a substance is; they can also be reversed. In a chemical change, a new substance is formed and energy is either given off or absorbed.
A barometer measures air pressure, but seismographs can record motion of the ground.
