Professor Newtoff
Приєднався 13 бер 2014
Hi! My name is Professor Newtoff and I teach Environmental Biology and Principles of Biology II: Ecology & Evolution. I started creating lecture videos for these classes to do a flipped classroom and to teach online. I'm a strong supporter of open education, so I have made my videos public to hopefully help students around the world! I do monetize my videos, but I exclusively only use skippable and closable ads. Of course, it helps me if you watch them or keep them up, but your education is more important! I try to stay on top of comments, so if you have a question about the content, want me to share my sources or slides, please let me know and I will get back to you as soon as I can!
Recycling in Montgomery County, MD
While this video focuses on Montgomery County, MD, many principles of recycling from this video can be applied to many other municipalities -- especially with recycling plastic films! Here in the county, we use dual stream recycling, but single stream is more common across the United States. Europe utilizes multi stream, having many different containers to separate out recyclables. How well and often resources (particularly plastics) are recycled is largely dependent on how well residents are sorting their recycling, especially in dual and multi stream programs. Single stream programs have many issues trying to sell their recyclables since there are so many impurities in the product.

The first part of this video explores some trends in waste in the United States, but then gets specific to how Montgomery County, MD handles their solid and hazardous waste. We use the waste incineration to energy process, which only a few dozen places in the U.S. practice (though, this is a lot more common in Europe where land for landfills is harder to come by). But, no matter where you are i...
The Scientific Method: What It Is and How It's Part of Your Daily Life
Переглядів 1025 місяців тому
I can guarantee that you have used the scientific method sometime in the past week. We use it all the time, and we don't even realize it. We have this innate ability to reason through different scenarios, test them out, and try something new. BAM! You just did science! From figuring out why your video game console isn't working to understanding the variables that impact plant growth - you are d...
Impacts of Climate Change on World Temperature and Weather Patterns (2024)
Переглядів 1545 місяців тому
With an increase in greenhouse gases in our atmosphere (mainly from the burning of fossil fuels), it's to be expected that the greenhouse effect is strengthened and more warming occurs. This videos talks about trends in global temperature and it's impact on weather and sever storms such as hurricanes. In addition to exploring these impacts to humans, we also explore the impact it is making to o...
How are Fossil Fuels Made?
Переглядів 1095 місяців тому
You have probably heard of the fossil fuels: oil, natural gas, and coal. But where exactly do they come from? What made them? What are they made out of? This video explores all of this and more in an effort to better understand how combustion of these fuels leads to carbon dioxide emissions (in a future video). I would encourage you to watch my entire Climate Change playlist (ua-cam.com/play/PL...
Carbon Dioxide (CO2) Emissions by U.S. State
Переглядів 1455 місяців тому
Most air pollution laws in the United States are regulated at the national level, so the state data isn't THAT important. But, the state level data can provide interesting insights into how carbon dioxide emissions differ based on infrastructure and population density. This video was made with the most up-to-date information available in March 2024. I'm not updating these videos every year, so ...
Carbon Dioxide (CO2) Emissions by Country
Переглядів 2015 місяців тому
At the end of the day, the total amount of carbon dioxide emissions is the most important, as CO2 from anywhere will affect the climate everywhere. But in reality, we don't have a global regulatory body and emissions are regulated at the national level. It's important to understand how a country's development, culture, and population all have an impact on emissions and how other countries can h...
Combustion's Impact on the Carbon Cycle
Переглядів 1565 місяців тому
In my carbon cycle video, you learned about the different slow and fast carbon pathways that carbon takes to move throughout Earth. However, a new pathway has been added by humans: combustion (essentially, fire). While combustion existed before humans, humans have been using the process of combustion a lot more as we use our ingenuity to put combustion to work. However, this process is taking c...
Changing Carbon Dioxide (CO2) In Our Atmosphere
Переглядів 825 місяців тому
Logically, it makes sense that carbon dioxide is increasing in our atmosphere. Humans burn carbon based fuels such as wood, coal, oil, and natural gas and in the presence of oxygen, it will make the byproduct of carbon dioxide (CO2). But just how much CO2 have we been producing? And how much more is that compared to our past? How is what is happening today any different than what Earth naturall...
Some Water Pollution is Okay: The NPDES
Переглядів 3186 місяців тому
The NPDES (National Pollutant Discharge Elimination System) is a permitting system in the United States governed by the Environmental Protection Agency under the Clean Water Act. This permitting system allows entities to pollute, but is regulated in the frequency, type, and amount. Nature CAN break down pollution on her own, and this system takes advantage of that fact. Unfortunately, our techn...
A Flash Talk of a Flash Talk (or a PechaKucha) and Tips on Making One
Переглядів 1736 місяців тому
A flash talk (or originally a PechaKucha, created in Japan) is a presentation style to share information in just a few minutes. It's hallmark is that it is an automatic talk; the slides advance automatically after a predetermined amount of time. The flash talk presented here has 10 slides each for 18 seconds, resulting in a 3 minute presentation. This isn't a standard though, different organiza...
Regulating GMOs (with a focus on the United States)
Переглядів 2037 місяців тому
GMO crops are here to stay, but countries are making decisions for themselves to allow them to be grown within their borders, to be imported as goods, and to be sold to their population. The decisions countries make for themselves can also provide some input on how they view the safety of GMO crops in regards to human health and the environment. This video takes a closer look to the GMO labelin...
The Impact of GMOs on Human and Environmental Health
Переглядів 7027 місяців тому
The BIG question when it comes to GMO crops (and other food items, though, not explored in this video) is "Are they safe?". And that answer really depends on what we consider as safe, and safe for whom? This video explores the timeline of GMOs and its relationship with human health and also explores ways that GMOs can affect our environment. Some other videos that may be helpful in your underst...
Class Trematoda: Flukes not Flounder
Переглядів 6448 місяців тому
One of the classes in Phylum Platyhelminthes is Class Trematoda, which contains all of the flukes. All of the flukes are parasitic with some using one host and others using two (or more!). Despite the variation in life cycles, they all share that at least one of the hosts must be a mollusk, such as a snail, octopus, or clam. Some trematodes can even use mind control on their host to make them d...

Subphylum Vertebrata: Ectotherm vs Endotherm, Heart Chambers, Cartilage vs Bone
Thank you so much for your clear explanation.
Chitin is also found in fungal cell walls. Just felt like i had to mention it. I’m really enjoying your lectures. I really should be focusing on higher plant and invertebrate systematics right now, but I’m really enjoying procrastinating by reviewing knowledge from previous semesters through your narration.
I was seriously fully prepared to fail my invertebrate exam. You are an amazing propagator of knowledge, i am SO glad i went to UA-cam in my desperate inability to form actual maps of knowledge in my synaptic castle. My professor just dropped a script on me, and told me to learn the monotonous text in it by heart. Which i have epically failed at. You are ensuring i not just squeak through, but actually attain and retain relevant knowledge on the subject.
Immensely helpful! I wish my professor took the time to explain this, show us a Phylogenie tree instead of dropping a cryptic script for us to learn by heart, and buggering off.
you know when my lecture explained this ... i didnt understand him at all and that goes for almost all my zoology lectures but to have you on my side ... teaching me and able to understand what you are saying in any of your videos e.g the animal diversity, ..... actually i dont have the words to thank enough ... thank u so much
I'm from India and this class was really helpful for bsc u know 😁👍 So I'm here to thankyou dude💖
Touching on the conifer-pine relationship, are all conifers pines, or pines just one of the categories making up the phylum. I gots to know... thanks.
Can't find the link 😢
I am watch your video. Are you a Teache of class ix . Thanks mem, I am Indian
Excellent, just what I was looking for. Thank you
Cheer~~~a large phylum that comprises the segmented worms, which include earthworms, lugworms, and leeches.😊
hi mom! 🤗
There are some pretty big cephalopods out there
Man, imagine 100,000 years ago! Out current cephalopods have nothing on today's ones!
THANK YOUUUUUUU
Is that a nematode infested heart😨
They are! This is why it is so important to give dogs heartworm medication because heartworm is spread through mosquitos. If you live in a temperate climate that is being affected my climate change, you really have to do heartworm year round, not just during the summer.
@@ProfessorNewtoff That is truly gruesome!!
I wish you had a video on Phylum Nermatea.
If I could like this 100 times I would
❤❤❤❤❤❤❤❤
Good😊
Thank you so much
Your videos are literally such a blessing. Thank you for what you do!!

Your method of teaching is very impressive!
Annelida is Best phylum ❤❤
I loved the explanation. It is very clear and easy to understand. Tomorro, I have my last quiz for the semester, and it is about gymnosperms. Thank you
I hope you did well on your quiz!
Thank you so much profesa.. I'm watching from Kenya and really happy for your work
Thank you i studied that too, phytoplanton, zooplankton, bentos and solaria.
Thank you so so much- I took plant pathology and although I really tried to enjoy it and do well, my professor for all her great virtues and knowledge had the thickest accent ever and went so fast it was hard to keep up. Thank you so so much for sharing this info on UA-cam it is insanely helpful to have thorough and detailed info in a video format
You're so welcome and I'm glad it's been helpful!
you’re the best teacher ever
Please come tell my current students that :)
love the way how you explain things ... you are an academics savior ..between my zoo lectures and you ..sorry to say this but i would choose you🤗🤗🤗🤗🤗🤗
Sorry, not sorry!
Thank you
Your videos are so helpful, thank you
I love this

So asca (asci?) have 8 ascospores each, basidium have 4 basidiospores each, but sporangium have tons?
You got it! (And yes, it is asci, and basidia is the plural form). But, keep in mind there are thousands of asci and basidia on those shrooms, so even though sporangia have tons of spores inside of them, there's only one sporangium.
@@ProfessorNewtoff Thank you!
Good day Can we be friends i like your teaching, I'm a student of Animal and Environmental Biology
You ever wondering how a cephalothorax would look like just remember Kingpin from Into the spiderverse.
Thank you so much 🤍💯
the snails are so weird 😂😂😂😂
