Thanks for the video each week. They are very interesting.
i love science!*
This is so cool!!
i loved this weeks video
Interesting, still don’t like spiders.
you know every time i watch this I learn something new everyday and it helps me learn so much about science and how it can really think I can be more than ever so thank you accelus
This was such an interesting episode! So happy to learn about these new things such as that water spider every single week. 🤍
That was super cool always learning new things
this was so cool and entertaining !
The water spider is insane!
Spiders have always creeped me out but that was interesting to learn!
Acellus has saved my grade and it helped me catch up on my learning.
heyyyyy from California
Watching from Texas! The Science Live lessons are always pretty cool! I always learn a lot from them.
I have noticed the great increase of students commenting on and watching science live! It is so amazing how more people are starting to use this amazing platform! I have used Acellus for about 6 years and I absolutely love it!
the little acd2 dancing is cool.
I loved the water spiders!
I loved this one!
This was so much fun
wow i learned a lot!
We love Lady Pajet! My daughter loved her as a teacher 😉
Thank you! These lives are so cool.
New fear unlocked; water spiders. I’m joking, but I will say that they are really interesting and I enjoyed learning about them. I really enjoy science live and Acellus as a whole; I was wondering if there is a way that I can still watch after I start college this fall?? Love always, Rileyann K.
I love ACD2
I love weekly Science Live videos, learning about the spiders was my favorite part!
This episode was so cool!
This is so cool!
it was cool seing how the chips worked also could they use the water resistant thing on electronics to they wont break
this was so 😎
I loved how the Robot danced to the Acellus song!!
That is interesting that the heat went through the plastic bag but not the guys glasses. I wonder what other materials it can go through or not go through.
This is cool!
R 51 rocks!
ifrared light is amazing when it comes to health care
Wow! The Binary Decade Counter is so cool and interesting!
Seeing Kelsey’s story was so inspiring! Does Acellus plan to add an animation class or a graphic design class at some point.
Hello from Virginia
Can you make other materials “super hydrophobic” or is it just metal?
Invisible light such as (Ultraviolet ) is electromagnetic which forms radiation. Plus, invisible light can be transferred into thermal energy which is caused by matter being absorbed.
wow binary decade counter was amazing love live science.
I like the end it was funny
The water spider was my favorite section of the video.
it was nice to learn about capacitors.
binary decade counter is super cool
Wow it was so cool!!!!!!!!!!!!!!!
I learned so much this episode!
The dancing was fun!
I like watching Science Live
tuning in from texas
I love ACD2 dancing it’s so cute!
wow so cool I love hydrophobics a lot to see!!!!!!!!!!!!!!!!!!!!!!!!!!!1
omg this live is so cool I literally can’t wait for the next one.
these keep getting better
do more water sagments
very fun science live today
That’s cool that spiders can breathe underwater with a bubble and carry it around.
would like to hear more about Binary Decade Counter
Area 51 was funny
I loved learning about the different temps make different colors.
how long over the years i find it cool and interesting how much you do with coding.
EPISODE 298 was a good one cant wait for next week
What is the difference between synchronous and asynchronous decade counters?
Loved the spider part
Very fun lession today, this is my first time hearing of a water spider.
I love how Lady Pajet came up with the word Socional, it’s something very smart and actually makes a lot of sense when you think about it.
I really enjoyed the spider segment!! Love science live!!!
very cool fun stuff to learn about
Hello from Georgia!
Binary Decade Counter
this was interesting
i am absolutely terrified of land spiders and you mean to tell me I have to worry about water spiders too?!
Wow, It’s so crazy how much science is still being learned and discovered. Like how the sun is different colors, and all types of spiders I didn’t know about! Cool stuff.
please someone tell me the F-47 doesnt look like a dorito SU-33
I love the Binary Decade Counter!!!!
It was so cool how the super hydrophobic did not sink!!!! I also loved ACD2 dancing!
I LOVE SCIENCE LIVE!
I think I must be a flip flop! In all seriousness, the circuits lesson was really interesting!
Science is the best!
I am so happy for Kesli Russel, for her to be able to accomplish some of her dreams and advance them is so amazing!
Loved this video.
I liked watching the video.
Howdy from Texas! This was a very cool episode of Science Live.
Hello, from California, great video thanks.
Awww the robot!!!
I did not know thats how ultra-violet was explored, this video was so fun to watch i enjoy watching them everyweek.
Loved this weeks video!!
how hot is infrared?
Loved this episode today!!
i loved watching the little guy dance, not to mention how cool it was when the hydrophobic didnt sink within
tank you for this nice episode can’t wait for the next.
This was amazing! I learned some new stuff today!
this was so cool to watch
That was a good fish joke!!
I loved learning about the binary decade counter this Science Live!

Thank you for teaching us what a infrared and ultraviolet is! I always wondered!
And I have some curious question, does Pajet Monet is french?
Hi from Indiana!
I think that the robot was very cool and it was cool that it could dance.
Binary Decade counter is sweet!
Did r-51 use the serum?
Great job! thank you!
ACDS dancing was great
I did not know that there was a spider that lived under water with a web sack air bubble. That is amazing!
This taught me so much! I’ve been trying to get more into binary.
Water spiders are so cool! I loved this video!!
so cool to learn about sipders
spiders are so cool!
I loved this episode one of my favorite ones
this was a very interesting and informative video .

How did acd2 perfectly dance with the music?
I really like the idea on spiders and hydrophobic way they live on the water!
Electronics are amazing and came so far. Love Science Live!
Best part of this week
What does a water spider eat?
It’s cool to learn about water spiders cant wait for next live!
This was bout the most educational thing i watched SO far i’m sure there’s more coming!!
Such fun watching you all!!
a water strider or spider floats on water like a giant walrus both because air is lighter than water
How hot does infrared light get?
the robot was way bigger than i thought
Loved this live.!!
I think my favorite part was when Dr. Tobias said “In the year of February.”
I like computers are so cool.
how does water spiders live in water.
i like science live it was cool
Is there social and emotional classes for every grade?
I liked learning about how different colors of light produce different temperatures.
Another great live. Water spiders are pretty cool.
I did not know the technology about invisible light; I learned alot from the video
Again super exciting insights into science themes. Never forget, there is more than the eye can see!
Lol r51 is soo funny lol :]
Do you think that spider pattern would help in space as well?
