HARD Science Quiz - 20 questions - multiple choice test 

18 out of 20....I was most surprised by the diamond as the best conductor of heat.

Johann Pachelbel ‘Canon in D’ - one of my favourite scores - originally composed in 1680. Such genius!...

"Your Job" and "Murphy's Law" made us lol. Also, embarrassed how few I knew.

Very interesting quiz .. learning is fun. At age 60 living in Canada. Highest education completed , gr.8 ... and scored 50%. Happy with that , even though would be a fail. Cheers ! Thanks for this.

18/20....and I used to be a high school physics teacher! I struggled with a couple of the biology questions.

OK, you got me with the “Your job” answer to the question about going along with a group consensus. I laughed so hard I saw stars and got lightheaded.

I found this more of a vocabulary quiz than a science quiz.... 15/20

Good quiz. And I appreciate the explanations along with the correct answer. Keep it up.

when comparing the relationship of the moon to earth try using diameter, mass or volume rather than 'size' as they are all different. It's diameter is about 27% of the earth but it's mass is just over 1% so 2 of your answers are both correct

Happy with getting 11.Would be happier fining other quizzes as well put together as this one.Very enjoyable and brain testing.(remembering, lol)

By volume, the 2% is best for the moon. The question doesn't specify what we're measuring. And by mass, it would be 1.2% Several other questions were technically incorrect or ambiguous. There was nothing I could not answer before consulting the options except most chromosomes per organism. (trivia) 19 of 20.

15/20...good quiz. The question about the moon was ambiguous, though..."size" could mean either diameter or volume, I think.

PhD Chemist and scored 15. Very thorough quiz across physical, biological, and social sciences.

As an 8th grade Student turning 9th this year, I can conclude that the test was indeed hard. I haven't heard/learned some of them, and now I am willing to learn new things after watching this video. If you're ever wondering how many scored did I got... I've got 14/20, some of my answers are just a guess, I was pretty lucky, ain't I?😆

Finally, a decent quiz on YT! I got about half right. I suck at biology. Pretty good with chemistry and physics.

This should be called a life science quiz. The physical science and math questions were trivial.

Well...15/20--not bad for a postal worker, eh? I had majored in astronomy at uni, and just stayed very interested in matters scientific since. A very enjoyable quiz!

I enjoy learning new fact. Especially ones I don't normally run into

I enjoy these questions because they are fun and memorable.

Question 2: you have to specify what you mean with "size". Volume? Diameter?

15/20... Like, Really! We're going through an extinction right now!!?!??

17/20 I'm 62 and completed school 45 yrs ago with a GED, I think i did ok

Nice questions. Even more, I like the music 🙂

That test was tough ; definitely for science people . I got 6 or 7.

Finally, a YT quiz that is challenging.

12/20 - Not bad for a non-scientist. Enjoyed it!

19/20. I was a chemist at Celanese for 32 years before retiring, with a phd in molecular biology, so I guess I had a small advantage.

For the educated,but non-science-specialist layperson,that was indeed hard 13/20

Interesting. Really enjoyed that. I scored 9, which I think is not bad. Loved the tunes🎶

I got 16 out of 20. But I did study science at university. The question re the Moon was ambiguous as it didn't specify diameter or volume or mass.

I got 7/20 I study in class 9. I'm from India. My age is just 14 😎😎. I love to study physics, chemistry and maths.

12/20 But got five of the first seven wrong so a bit of a comeback :) Good channel

16 right so not too bad. I was a bit slow at the beginning though, and while I knew a strawberry had more chromosomes than a human, I didn't know the same about a pigeon.

Am I the only one in this comment section who is still in school.

12th grader who scored 19/20.. The questions were stupendous!!

"Your job" was a funny one. But the quiz is like a 25% basic science quiz and a 75% random facts quiz. Still got a 100%.

I got fifteen right. Here are some points to consider: 1. For the question about atomic number, the number of electrons is as good an answer as the number of protons, because the number is the same. If there is any difference, it's not an atom, it's an ion 2. The explanation for the last question listed "farming" as a cause of extinction separate from "agriculture." What distinction are you making?

it is harder than the papers I did ... but thank you ... it improves my knowledge 😢

I got 6 out of 20 for a non- scientist. This really is hard! Try making this a little easier, but overall, this is great.

Thank you so much ,with thisIWill studied something else

Great quiz! I thought I was much better informed, but to my dismay, I seem to have a few gaps in my science knowledge. My score? Embarrassing.

Slipped up on just a couple. Didn't know that diamond was the best heat conductor. Interesting.

I found that one very hard. 7/20. Great quiz.

I got 11 out of 20.The questions are seriously perplexed but with critical thinking I strive to choose the correct answer to the question.

There were a couple I had never heard of, so I am excited to learn more (if my old brain can remember it later Lol!). A couple lucky guesses and a few I did know, but not as many as I hoped. Great quiz! I also appreciate the follow up info supplied afterward. It helps put answers into context.

Got 14, but some of them I got it as educated guesses, like knowing that prefix "an" means "lack" and things like that.

Ouch! I don't mind missing the ones I never knew, but the ones I used to know and couldn't remember bother me. My fossilized old brain missed 7 of these, but I did learn a few things.

I like your quiz as well as your tuning It's is amazing I like it

17/20 Enjoyed your quiz. I did pause on many to think some through. 😀👍

The moon is 2% of the size of the earth. The word size is the problem. If you were to ask me the size of two baseball bats, that is most often a linear concern.. A sphere however is a cubic object, 3 dimensions. The moon is 2% of the size of the earth.

Yaayy!I just got 16 marksssss

I gave this quiz to GPT-4-turbo, and it got 18 of 20. Although it knew, when asked later, that diamond has a much greater conductivity than copper, it chose copper for Q 1. It also knew the number of chromosomes for every choice in question 13, but made a simple arithmetic mistake by saying that 56 was greater than 80 - this type of arithmetic mistake is a known issue with Large Language Models. - I had initially given it a version of the test without the multiple choices, and it answered all questions that were not open ended correctly and gave an explanation. - I then gave the same test to Claude 3 Opus, and it made the same mistakes. When asked to “think step-by-step”, it got the answers to questions 1 and 13 correct.

My score was 13 nice, I didn't knew many of the things that were asked in this quiz but yes this was enjoyable,I look forward to more quizzes like these,I recently passed 8th grade and now I'm going to join 9th grade,thank you very much for this kind of content..

Fair amount of science knowledge. Difficult test. I learned a lot. #2 is not a valid question. Size is not specific. Scored 13 out of 20.

14/20. That was a tough and fair quiz. I would like many more like this.

SPOILER: I don't really agree with the definition of groupthink. It's not staying quiet but secretly disagreeing; it's actually thinking the same way as others of the group - subconsciously following their way of thinking. It runs a llot deeper than being politic.

There was no notification that I had to keep my own score so I'm going to say I passed but my instructor needs more improvement. He does play well with others though.

I got 17 right. A couple were educated guesses and one was a flip the coin guess. Good quiz.

Got 15/20. I had a few problems with language. I'm Italian and studied in Italian terms are often similar, but sometimes totally different. However I figured nearly everything. Only 1 error, I think, could be because of language

Great quiz. Not easy so really got me thinking. 16/20.

Really good 👍 keep it up

I got 9 correct and guessed correctly in 3-4 of them. It's quite hard quiz but anyways got to learn so many new things today.

Love this, I learned a few new things!

More of science quizzes please😊

That last question strayed outside of science bounds.

I have lived all these years and not known hardly of any of these answers. I'll still sleep tonight though.

16/20 but I'm ashamed to say I got the Newtonian question wrong.

I only got five. That’s better than I thought I would do-science isn’t my bag. I only took four science courses in my entire schooling, and I flunked one of them. I only stayed for the jazz. 😂 Michael Del Brown at the end there. Good taste.

I usually count the ones i get wrong. Not this time. I'm not playing anymore :)

Good quiz, got a 13. Don't listen to the comment about making it easier, the difficulty made it more interesting.

Got 10.Glad I got them!!Learned a lot!!!

Excellent quiz. I got 12 of 20. Not great, but not embarrassing. I'm going to try history next.

*The correct answer to #20 is "The Leftist Effect"*

Only missed 2. Thanks for a good quiz that wasn't the same old, same old stuff!

16 for me. Not bad for someone who left school nearly 60 years ago.

18/20. Missed #1, which drat it all I should have gotten , and #13, which I didn't know but went for strawberries because I knew they have more than humans.

18 correct. I am a retired science teacher. I should have got the moon size, I suppose, but it was poorly written. Is "size" diameter, volume, or mass? I knew that the moon's gravity is about 1/6 that of Earth. 1/6 is 17%. The chromosome question seems quite trivial. We should know the number of chromosomes of every species? And there are no principles to apply to guess the answer, because chromosome numbers are largely arbitrary.

9 right but pleased. great quiz

My score 14/20

Got an 18. I was quite surprised that diamond is the best conductor--I always thought that it was Gold, with Copper as second. Also didn't know that pigeons have that many chromosomes. I guessed strawberry, as I know that some plants have a ridiculous number. Nice quiz.

Thank u this helpad me in my iq sci exam 😊😇

Got 15/20 Really interesting

whats this song like a violin

I got 20/20! I'll say it is quite good for a 7th grade student. I'm so happy. 👍👍

15/20. That was seriously difficult for a non-scientist, but a good challenge. 👍👍🇬🇧🇬🇧

I am no scientist, but I consider myself to be fairly well read in the arena of science and I got 9 right although there were a couple that I got right and then changed my mind, gotta learn to trust my instinct. That was a truly testing Quiz, which makes a change on YT, I usually find myself getting 80%+ on these so called hard quizzes.

14/20, very hard, mostly because it is multidisciplinary.

17/20, Diamond question (#1) had a surprising answer. Request: please make these quizzes quicker: i watched this one on speed setting 2, and i had to wait and wait for the answer. With the science you either know or not, there is no need to have time for guessing.

Hard but I enjoyed this video ❤ 😂 🎉 😢😮 😅

As a 4th grader this was easy!! 20/20

14/20 I never knew some of them but I learned new things 🥰🥰

Good Quiz! Thank You!

10+2 successful educated guesses. Absolutely no idea of the rest, I could only eliminate some answers but no more than 2 in any of the 8 remaining questions....

For the Moon-Earth question you need to specify whether you mean diameter or volume. For volume, 2% is the correct answer. The last question: there is no extinction caused by 'ocean acidification'. The ocean's pH has changed from 8.2 to 8.1 in a century and is still stubbornly alkaline. That change is much smaller than natural variation in pH.

15/20. Your question about the Moon's "size" is ambiguous. Your answer was comparing diameter, but it could also have meant volume or circumference.

That was more than hard, 3/20 doh!

Okay. This one was much harder than the previous science trivia quiz. 18 out of 20.

Indeed, this was a hard quiz. I missed 1 question, and that was #4...(3!).I took 5 years of mathematics in 4 years of high school, (algebra 1 & 2, geometry and solid geometry, and trig.. and don't remember ever seeing or learning what that meant. Anyway, I learned something new and that is great. I am 75 and a person should never stop learning. You do a great quiz. Thank you! 😊 👍 🤔Keep making us think!!

Well, that was humbling. Especially the first 10 questions. I did avoid complete embarrassment on the last 10. Back to Khan Academy for me.

12/20 really difficult, but now I know all the answers: I've learnt a lot!
