Science Quizzes

Type “start” to begin. You will be given a multiplication question right beneath the typing box. Type the answer as fast as you can – when completed the question will change. You begin with answers of less than 100, then move up to answers with higher and higher values as you progress. Try to complete as many answers in one minute as you can. You are scored based on the total digits in the answers to each multiplication question.

Upon typing 'start' you will be shown animal images. Name the animal shown. Usually I'm looking for a specific name, not just 'monkey' or 'whale' - however some are just the general name. I'm not looking for regional/descriptive names such as 'American' or 'Blue-Bellied.' 25 random animals shown from over 300 total. You get 5 minutes and 25 sec max per image.

Name the families of bird species according to the IOC Bird List 12.1. Some alternate names are accepted, however you must be naming the family name and not a species within that family. # of species shown. Object is most total species not families. Answers should be the English family names.

Name the 206 bones of the human body (120 different names). You typically need the actual name of the bone, not a more commonly known name. Object is most bones not different bones (i.e. paired bones count as 2).

Name the branch/field of science dealing related to each description. Many - but not all - answers end in -ology. The description is what the branch is studying/focused on.

Name the 50 brightest stars by apparent magnitude. Magnitude and constellation shown.

Name the 88 constellations recognized by the IAU (International Astronomical Union). Sorted A-Z. 'Ancient' refers to the original constellations listed by Ptolemy (one of which was split into 3 which are all listed as ancient).

Name the chemical elements with 6 or fewer letters in their name. Sorted A-Z within each length. Letters in name are based on American English spellings.

You get 2.5 minutes to identify as many flowers as you can from their image. Upon clicking start, you will be given a flower's name on top of the table of 25 images. Double-click on that flower's image to choose it. If you guess correctly, it will add toward your total and that image will be removed and the images will shift with a new one being added in the bottom right. If you guess incorrectly, you are penalized 5 seconds and the image you click on is still removed and the images shift with a new one being added.

Name the last word of the common names of all mammal species according to Wilson & Reeder's Mammal Species of the World 3rd Edition (2015). For example, if this were reptiles the "long-snouted grey alligator" would be answered with "alligator" - all species ending in that word will count when answering that final word. Total species for each final word shown. Object is total species, not common names. The final word must match exactly with the documented common name in the source. A handful of alternates are accepted for compound final words.

Name the organs of the human body. System shown, organs listed A-Z within each system.

Name the elements with 1-letter symbols on the periodic table.

Name all of the elements - group (type as well sometimes) and atomic number shown.

Name the elements of the periodic table in order from lowest atomic number to greatest. Naming an element that isn’t the next answer will count as a ‘strike’ against you. You begin with 3 strikes but get an extra strike added for every 5 elements you complete - so you can increase the number of strikes available by completing the 5th, 10th, 15th, etc answers.

Name the Atlantic hurricane names which have been retired - names are retired due to the storm being particularly deadly and/or damaging. Names sorted A-Z - year and areas affected shown.

Name the SI derived units with special names (non-generic).

Name the SI metric prefixes for each multiple/submultiple of a unit.

Name the named (i.e. given an actual name, as some newly discovered moons have not been named) moons of solar system planets (non-dwarf, sorry Pluto). Sorted by planets, then by size, then name A-Z. Planet and mean radius in km shown.

Name the top 100 prescription drugs by total prescriptions written in the US annually. Generic name is shown as the answer however many brand names are accepted. Total annual prescriptions shown.

Name the units of measure for each of the types of measurement. The number is the number of base units (i.e. meters) that particular unit is. A '1' is therefore the basic unit name. Not all units are widely used, and for some which are different depending on the country, I typically used US quantity. For temperature the number shown is absolute zero in terms of that unit.

Name the currently operating US nuclear power plants.
