Brain power!
Dr. billings is so cool, i love Acellus.
A ham radio class would be cool.
Acellus is amazing i love how Dr. billings takes his knowledge and shares it to us students it is truly amazing and inspiring!
I always wondered how radio waves worked, but now I know because of this video!
I really liked Dr. John’s segment on lasers.
I loved getting to hear about Mr. Roger as a kid and his love for radios! My favorite episode yet!
I will miss SL as i am due to graduate in december!!
I enjoyed the Science Live this week!
I love being able to dive deeper and learn more about science through Acellus!!
It is very interesting how NASA was able to find a watch for Apollo 11.
Science Live is the absolute BEST. Just my opinion 🙂
A very interesting subject today!
wow that’s soo cool!!!!
if a watch had to much air in it could it be destroyed in space?
I love my school
I love watching these science lives.
I love Acellus!
How do you make diamonds?
This is very interesting! I loved learning more about Radio Waves!
Science lives are so interesting, who knew lasers have more than just a toy and a light powerful enough to burn thinks, don’t forget light too if you think about it. Engineers and inventors are just brilliant.
My favorite is learning about going to the moon.
It would be great to learn how to be a pilot!
I want to go to the moon some day!
Aviation class sounds like a lot of fun!!
I actually really enjoy Dr. Tobias!
I love Roger Billings radio voice!
i love watching science live each week!
Omega is my favorite watch brand, it’s cool their watches had a role in the Apollo missions of all things.
Dr.billings is very smart
We love acellus!
First, we learned about the powers of the parent of an Acellus learner. There is a page in the parent area of Acellus which grants them access to know how much time it will take to finish a subject, our grades, and everything we do on Acellus. Parents can also change our steps, add new courses, and peek into our school days. From my own personal experience, they know how to know when you’re cheating on a review by skipping all the questions.
Next, Mr. Tobias told us about the Omega Watch. It was used by astronauts in space to keep track of time. It saved lives countless times because time is crucial in space. Everything in space is scheduled down to the second. Without watches, people could run out of oxygen because they forgot how long it had been since the last refill.
Lastly, it’s your favorite robot R-51! Today he tried to use a microphone to call up Pajet’s planet. I don’t think he knows that he’s on it. He accidentally reached out to some Martians and transported one to Area 51! Now he has a little friend that can keep him company.
Acellus has been an amazing learning path for me!
When did you first get your idea for Acellus?
Love Acellus! 🙂
I love Acellus!!! And I love Science
The story about the watches was really interesting. I never thought it’d be so important for astronauts to keep track of time and to think it even saved their lives to have those watches with them.
I liked learning about how lasers can cool things down.
science is really interesting.!
Who built the strongest laser ever?
i thought that the morse code was very interesting.
Thank you Acellus for the science live!
My Apple Watch has snoopy!
Who discovered things could be fluorescent?
Hi, Great episode! Really liked hearing about the astronauts and their watches!
I love Acellus!!
I enjoy science live a lot!
Acellus has made learning fun again thank you Acellus
We love the new things we learn from Science Live!
I love the science lives, it’s a great way to learn many new things!
THAT WAS COOL
Dr. Billings do have any ideas what jobs will be availible in the future? Is there anything specifically that I should study very hard to become better at? Also, how old do you have to be to get a license to use a radio? Were you a teenager? Can kids do it?
I love the classes on Acellus!
Radios are an essential part of society, and I found this science live interesting.
so thankful for Acellus!
I love listening to the radio!
Everything in Acellus is so cool! I can’t wait for the next Science Live!
Do astronauts in other countries have different space suits?
I love Acellus!!!
I love the science lives so much. Its so entertaining!
Science live is so cool i am learning so much!
hand radio class would be fun. I would be interested.
Pilot and helicopters class would be awesome. My older brother would be able to take it next year in high school. Me and my brothers would love to do the pilot program!
Acellus is the best!
radio waves are fun to learn about
In this science live, they talked about many things that you can do on Acellus Gold, pontuation, and daily goal. Tobias talked about watches and analysis in relation to temperature, shocks, vibration, and pressure that they will have in space. Roger Billings and Pajet talked about radio waves. It was so interesting!!
I want to learn how to be a scientist
Science live always teaches me something new!
Who would have thought that R-51 would communicate with Mars in such a funny way?
Acellus is awesome!!
I would be interested in a ham radio course.
Radio waves are cool, and I learned a lot.
I love how Rodger Billings explains science and makes it make sense!!!
I love science live because it teach me so much and i also love Acellus and the teachers because they teach me so much to !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I LOVE YOU GUY SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!
Science live makes learning so fun!
Rodger Billings is so great at explaining science in full detail and making it make sense!!
Science live teaches me so many fun new facts every week, always looking forward to it! Thanks Acellus team!
I enjoyed Dr. Billings teaching us about radio! It was funny to see a picture of his younger self climbing his radio tower, and hearing how his neighbors thought their stove picked up his radio transmission. R-51 communicating with Mars was even funnier! I would love to see new Acellus classes covering topics from this episode like radio, morse code, and aviation.
Watching this science live, I have made the goal to make something to help astronauts live in space.
This was a very good episode I enjoyed it!!!!!!!!
thank you DR.Billings!
I just love r 51 because he is super funny
I love watching these videos, learning new things.
Yes i believe classes in piloting skills and ham radio basics would be very useful, and even help with peoples future career paths.
Great breakdown! Now I’m wondering how frequency changes things like pitch or color in real life.
Science live is amazing I love it!
This show is so cool! It teaches me so much!
Science is my favorite subject! I like learning about Space.
How many hours does it take to learn to pilot a helicopter?
always love watching these guys teachhhhhhh!!
i love acellus is the best
How can Astronauts grow plants in space? By a controlled environment?
Learning Morse code would be pretty fun and cool!
Omega, founded in 1848 in Switzerland, is renowned for precision and innovation. It became the first watch on the Moon in 1969, when Buzz Aldrin wore the Speedmaster during the Apollo 11 mission. Omega has been the official Olympic timekeeper since 1932. The brand introduced the revolutionary co-axial escapement in 1999,
reducing friction and improving accuracy. Its Seamaster line, launched in 1948, is famous for diving performance and as James Bond’s watch since 1995. Omega also pioneered anti-magnetic movements, with some models resistant to over 15,000 gauss. Part of the Swatch Group, Omega combines heritage, technology, and style in every timepiece.
Comment very interesting on the best way to study to retain more information. I am going to discipline myself to try studying this way better.
Could you do a Careers class? I think it would be extremely helpful for those who are deciding on their future career paths. I also think that a baking/culinary class would also be interesting, because not everyone have a grandma they can learn cooking from, so I think that would be very fun!
DrB is so inspiring.
I really love what you said about florescent colors.
it was awesome me to i love acellus
It’s cool that a laser can cool stuff down like quantum computers I guess lasers can heat stuff up but also cool stuff down that is so amazing.
can Roger Billings do sience live every day? :>
I got to see the northern lights too! It was so cool!
The part about the Omega watch was cool.
Acellus is the best!!!
I 💙 Acellus!!!
I think its really cool that there was a watch on the moon
Acellus is amazing!!!!!!!!!! I love the library where you can read other students books!!!!
I love science live!!!
I have kinda always wondered why there are AM and FM and what the difference is between them.
I would be very interested in courses about becoming a pilot. Also, what about courses for air traffic controllers? Would that be something that could be done?
I think the laser segment was very interesting. I wasn’t actually aware that lasers could cool down. Like most people, I guess, I just thought they heated. But the fact that they can use it to cool things like quantum computers is seriously cool. And the bit about them maybe putting them into space was surprising.
I would be interested in taking the HAM radio course!
I really like being able to see how many steps I have each day. It helps me stay on task.
I love Science L!ve!
Learning about radio waves was fun!
I love these!I look forward to watching these every week
I love Acellus!
Radio waves are invisible, and can go long distances!
I liked when Dr John talked about lasers that can cool things down.
What time zone did they set their space watches to?
How do astronauts keep a schedule of everything they need to get done?
I want a course teaching us how to fly both airplanes and helicopters!
Science Live is so interesting each week.
Hi from Oklahoma! I love Science Live!!
I found this pretty interesting. I had no clue lasers could be used to cool things down
What is Mr. Billings favorite project he has ever completed?
Why do higher-frequency radio waves lose range faster than lower-frequency ones?
Can you still buy the watch that went to the moon
I love SL
I love science lives! Why is it when you practice learning, you can get better at them?
Will Am Radio always be around? And yes I would enjoy a class on HAM radio
How many snoopy awards have been given out by NASA
I saw the northern lights too!
Acellus helps so many kids learn and be better at leaning and that is why i love Acellus.
I love watching these Acellus videos they are very helpful.
I love Acellus
Science Live videos are so neat!
I would enjoy a Ham radio class!!😊
My favorite part of the week!
I love Science Live! Are radio waves safe?
Who inspires you the most today?
you are the coolest people in the world! Go Accellus!
Science Live is interesting!!!
I love watching these videos so much. They are fun and intertaining. I was wondering though if anyone can answer, do they have a video on the body or anything. I wanna be a Nurse practitioner when I grow up. Right now I’m 13 so I have a while before but I’m started to study for it right now and i have a 4.00 so I think I can achieve it.
I love acellus so much
I love Acellus!!
It’s so much fun to learn about new things!!!
I was amazed by R51’s segment this week; it was really funny! My dad is really into ham radios. I bet he would’ve loved this episode.
Great story about Snoopy! Interesting about the different radio frequencies. Some of my mom’s cousins have HAM radios and their license.
This Science Live was amazing!!
I enjoyed leaning about ham radios its such a cool way to communicate! I also think pilot and radio classes are a great idea.
This was a fun lesson!
I would love to learn Morse code!
love ACELLUS!!!!
How far can a radio wave realistically travel before degrading?
What affects the strength of a radio signal?
I liked how invisible radio waves travel around the world and even into space! Dr.Billings explained in a way that made it so easy to understand.
I thought it was interesting to learn about the technology of how people can communicate over distance.
Acellus is amazing!!!
I liked learning about how they made watches that went to the moon with the astronauts.
I love Acellus!
That is so cool how apollo 13 used the whatch to help them get back to earth.
I loved this episode about radio waves! It’s so cool how something invisible can travel around the world and even into space. Thanks for making it so understandable and inspiring.
With the laser to cool the I’m assuming computer chip idea instead of making it so that the laser turns off and cools whatever part of the chip was hot why not just have the laser on covering the whole chip so that it’s dosnt have to go off and on?
The worst thing about science live is that it ends
my grandpa has a Hamm radio!
Our favorite part was the story about the watch in space!
Why do you need a license to use a Hamm radio?
Acellus is the best ❤️
How long did it take to learn Morse code
We liked learning about the watch in space.
A class on aviation would be so cool! I would definitely take it!
I did not know lasers are used to cool something off!
What time zone did they set the Omega watches to?
I want to learn sign language. It would be great if Acellus had a sign language class, in addition to Morse Code.
can bioluminescent be considered as a strong flourescent?
we love acellus!
I love these science lives
I didn’t know that astronauts used watches in space! I’ve seen in movies where they used a watch to start the space ship while they were in it but I didn’t know real astronauts used them too.
