What are Significant Figures and how do you figure them out?
Scientists use significant figures to represent the accuracy of quantitative measurements. In this video, Justine Siew and Glorianna Tarlton explain what Significant Figures are, how to determine which numbers are significant in a measurement, and how to determine significant figures after mathematical operations like addition, subtraction, multiplication and division. They also describe how scientists used significant figures to study the evolutionary impacts of a hurricane on lizard populations!

Make your Grading Policy more Equitable with Multiple Grading Schemes!
Просмотров 2,8 тыс.2 года назад
When you use multiple grading schemes, each student is graded according to multiple grading policies, and they receive the highest score. This way, a student who scores high on assessments but low on "effort" can receive a high course grade, while a student who scores low on assessments but high on effort is still rewarded for their effort. 0:00 Introduction 0:15 The Problem 3:20 The Solution: ...
Don't Grade Homework for Correctness! Here's why
Просмотров 1,2 тыс.2 года назад

How to use M1V1=M2V2 to dilute solutions - AND - 4 ways to express chemical concentration!
Просмотров 15 тыс.3 года назад
M1V1=M2V2 (aka C1V1=C2V2) is a magical formula that lets you calculate chemical dilutions forward and backward. How much stock solution do you need to make a final solution with a desired concentration? If you dilute a certain amount of stock solution to a final solution, what is the final concentration? As long as you know 3 of the components, you can use algebra to determine the fourth! In th...

omg this was so simple and clear. thank you!
Thanks
I love your teaching
Can we have anything recent to measure color?
Fabulous explanation! Even my 6yo was able to grasp it 😊 I was also fascinated to learn how technologically simple the cure for HIV was. Genius!
I was in a ocean of videos on RUclips to understand the difference between RT PCR & qPCR, and then I came to get this pearl ✨🤌🏻...Thank you for this amazing video from where we can understand it so well 🙏🏻
🩷🤩
The semantics displayed here is cringe. Science does actually say God is the best explanation via deduction. Metaphysics requires God. Evolution could be true, but it’s more based on conjecture than observable Science (sorry, that’s the Truth!). You can’t prove God’s existence or evolution, but I’d place all my chips on God.
The way i’m learning more here than i have all semester in grad school. Thank you😭😭
Good video
Can l use a spectrometer to determine the color of tomatoes
😂 I also look up particular words for pronunciation.
Thanks for this systematic explanation
Thanks
You have absolutely wonderful channel, I wish you could keep creating more videos ❤
Hi thank you for this wonderful video. I don't know if you get this a lot but for a second I thought you were the bumbling biochemistry youtuber just aged a little lol but I don't think you are haha.
1:44 you said that there is evidence for god.. and then at around 2:11 you say there can’t be evidence for god, which is it?
it was amazing video thanks
Thanks Mam for elaborating it in a brilliant way!!
Thank you!
This is great
She is so cool !!!
This is the stupidest video I've ever seen

THANK YOUUUUUUUUUU SO MUCH.
Thank you for the useful content that you provide! Its very easy to understand when someone teaches with so much exitement and passion!!
Respectfully, if you are a Christian you must believe what the Bible says. And the Bible says that God created Adam and Eve to reproduce and basically increase the Earth's population. The Bible does not mention the evolution of monkeys, but just Adam and Eve, therefore the evolution is false.
Amazing. I never used micropipette in our university lab. I didn't have any ideas about it. But after watching the video. i learnt many tips Thank you so much ❤
