A milliliter of liquid is closest in volume to a: large droplet capful of liquid full glass full bucket Correct Wrong The size of a drop of water varies, but a milliliter is much closer to a single drop than to a larger volume. 2. Which part of a plant produces most of its food? leaves stem roots flowers Correct Wrong The green part of a plant contains chloroplasts, which have the chlorophyll needed for photosynthesis. While some food is produced in stems, most of it comes from leaves. 3. Simple machines that use ropes or chains are: levers pulleys wedges screws Correct Wrong Pulleys use a system of ropes or chains. 5th graders are expected to know the types of simple machines and have a basic concept of how they work. 4. Which of the following is not an observation? The clouds are gray. It's going to rain soon. I hear thunder. It is windy. Correct Wrong Saying it's going to rain soon is making a prediction. It's not a statement of fact. Once the rain starts, you can say it is raining, and that will be an observation. 5. You set up an experiment to see if soil type affects pea plant growth. The variable you change in the experiment is: the soil the pot the pea plant the water Correct Wrong In an experiment, you try to hold all variables constant (control them), except for one variable, which is called the experimental or independent variable. 6. The amount of moisture in air is its: density temperature pressure humidity Correct Wrong Humidity is the amount of water vapor in air. Hot air can hold more water than cool air. 7. If you cool a gas, it may ___ into a liquid: condense evaporate freeze melt Correct Wrong The phase change from a gas to a liquid is called condensation. A familiar example of condensation is when water forms on glass when you come indoors when it's cold outside. 8. The part of an atom with a negative electrical charge is the: electron proton neutron atomic nucleus Correct Wrong An electron is the part of the atom with a negative charge. Protons carry a positive charge, while neutrons are neutral. 9. The outer layer of an animal cell is the: vacuole cytoplasm cell wall cell membrane Correct Wrong The outer layer of an animal cell is the cell membrane. Plant cells have a cell wall that encloses the cell membrane. 10. When magma or lava cools, which type of rock is formed? sedimentary metamorphic igneous none of these Correct Wrong Cooled lava forms igneous rocks. 5th Grade Science Quiz You got: % Correct. 5th Grade Science Flunky Science often requires studying, or else you'll get a bad grade!. Rubberball/Mike Kemp, Getty Images Nice try, but you're not quite 6th grade material quite yet. One way to improve your skills is to learn science from performing experiments. Are you ready to try another quiz? See if you can recognize the chemical elements based on how they look or how much you know about food chemistry.

There were a few quiz questions you didn't know, but you're certainly ready to see if you know as much science as a 6th grader, or even a 9th grade student. Hone your experimental skills with fun science projects. Share Your Results 5th Grade Science Quiz You got: % Correct. Passed 5th Grade Science With Flying Colors A+ Grade. Ann Cutting, Getty Images Excellent! You made this quiz seem easy. Since you've mastered 5th grade science, why not try another quiz and see if you know as much science as a 6th grader. Or, change gears and see if you can recognize important (and sometimes weird) lab safety symbols. Another way to improve your scientific skills is to try experiments in your kitchen.
