High school science teacher Tyler DeWitt was ecstatic about a lesson plan on bacteria (how cool!) -- and devastated when his students hated it. The problem was the textbook: it was impossible to understand. He delivers a rousing call for science teachers to ditch the jargon and extreme precision, and instead make science sing through stories and demonstrations. (Filmed at TEDxBeaconStreet.) TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less).

This rap was created for a 6th-grade science classroom to teach about the different parts of a cell. With its catchy rhythm and rhymes, students of all learning styles and abilities will be able to learn about cells and their functions while having fun! Visit my Bandcamp Page to Purchase Cells Cells: https://crappyteacher.bandcamp.com Follow me on Twitter: @emilycrapnell Follow me on Instagram: @crapnellscience "Cells, Cells" Original Rap by Ms. Quitmeyer- Legal name now changed to: Emily Crapnell Today's the day were gonna learn about the cell If I teach it okay, you'll know it very well So listen up 6th graders- -no room left for haters- lets talk about the building blocks of life- cells that make us. Chorus: Cells, cells they're made of organelles Try to pull a fast one, the cytoplasm gels The nucleus takes over controllin' everything The party don't stop 'till the membrane blocks the scene Inside the vacuole we can float around for hours Running round with chloroplasts, lovin' sunlight showers Cells, cells, they're made of organelles First things first, there's two different types- animal and plant cells that make up all life. The little things that make up microscopic cells, The main structures- yeah, we call them organelles. Now let's break it down and get some information- How do cells work? It's a crazy combination! -Chorus- The cell membrane is the border patrol, Who can cross over? The membrane lets 'em know The gooey stuff inside, is called the cytoplasm It holds the organelles- don't worry, plasm-has 'em! In the middle of the cell you'll find the big brain, The nucleus surrounded by nuclear membrane Don't forget the vacuole filled up with water It's a basic need for life when this rap keeps getting hotter! -Chorus- The mitchondria's something every cell needs, Breaking down the food and releasin' energy. There's a place inside the cell where chemicals are stored, the squiggly golgi bodies, releasin' even more. Yo hangin' in the cell is endoplasmic reticulum, synthesizin' enzymes for respiration, and um... If you still think that this rap is whack, remember ribosomes making proteins gettin' jacked! -Chorus- Lookin at the plant cell, weird and green two more parts is all it takes you see? Cell wall knows what's up when it comes to keepin' structure Strong with cellulose, this cell can't get much tougher. C-H- L-O- R-O -- Plast, These little green machines are havin' a blast Photosythenisizing- filled with chlorophyll -they hit the cell club, runnin' up a high bill- -Chorus- Creative Commons License Cells Cells - Parts of the Cell Rap by Emily J Crapnell is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.

look at this fish swimming in the sea or the spurred up a tree. What about a bacteria or even a bumblebee. Don't worry I wrote mine for the entire video but the amazing diversity of life on planet Earth is truly staggering they are estimated to be between 5 to 10 million different living species on the earth and that's excluding all the bacteria as they are really hard to count. So, what do they all have in common what makes something a living thing. Well scientists have found that all living things from the simple little amoeba all the way up to Big Chill giraffe and everything in between can carry out these seven life processes. The fastest movement some organisms moves very obviously like a cheetah the fastest animal on the planet which can run as 60 miles per hour. Other organisms like plants move much more slowly but all living things do move. The second is respiration. Respiration is a process that occurs in cells to release energy that is stored in food. Organisms have evolved slightly different ways of doing this but all living things need energy to live and this is how they release them. The third is sensitivity in order for a living organism to survive it needs to be able to sense its environment. It could be to find food or shelter or avoid predators. But all living things have evolved at least simple sensors to do this. Humans have the five senses of touch, taste, sight, sound and smell which gives us a very clear understanding of our environment. The fourth process is growth all organisms grow in basic organisms the cell gets a little bit bigger. In more complex organisms you get more and more cells. Animals tend to stop growing in adulthood but some plant can continue growing and get very big, in fact the biggest living organism on the planet isn't a plant it's a fungus it's a type of honey fungus growing in Oregon and is thought to be 2.4 miles across. Fifth is reproduction some organisms can reproduce on their own such as bacteria this is called asexual reproduction. Others carry out sexual reproduction using a male and female of the species. Bacteria can reproduce every twenty minutes then African elephant takes 22 months to carry it baby. Excretion is a sixth process this is not the same as pooing which is actually called a Egestion but excretion means getting rid of waste and chemical reactions in the organism. Respiration for example makes waste products and each organism needs to get rid of these this is called excretion. The final process is nutrition every living organism needs some sort of food, plants can make their own food by the process of photosynthesis but all other organisms have to get their food from somewhere else however the process of obtaining food by either way is called nutrition. So, there you have it the seven life processes you can remember them easily by learning the phrase Mrs. Graham, movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.

NITROGEN CYCLE:Nitrogen is the important essential element for all living organisms by the synthesis of Amino acids, proteins, Enzymesetc.What happens if there is no Nitrogen?. Root systems and plant growth are stunted.Older leaves turn yellow.Decrease in crop production. Soil microorganisms life become dangerous.In Atmosphere its concentration is 78 percentage.The circulation or cyclic movement of Nitrogen from the atmosphere physical or abiotic component to soilBiotic componentand back into the atmosphere is known as.Nitrogen cycle involves various steps:1.Nitrogen fixation. 2.Nitrogen assimilation 3. Ammonification 4. Nitrification 5. Denitrification. Plants cannot utilize Atmospheric nitrogen so it should be converted into utilizable form such as Ammonia.1.Nitrogenfixation:This is the first step of Nitrogen fixation.Conversion of atmospheric nitrogen into Ammonia for living organismsis known as Nitrogen fixation.This process is carried out by leguminous plants such as ground nut; even some bacteriacan fix atmospheric nitrogen.Examples of bacteria --Azotobacter Clostridium, Rhizobium, Nostoc and Anabaena2.NitrogenAssimilation:The process of absorbing Nitrates and Ammonia into Organic nitrogen is known as Nitrogen Assimilation.This organic nitrogen is transferred into animal's body when plants are eaten by animals. 3. Ammonification:The process of converting organic nitrogen into Ammonia when Animals die is known as Ammonification.It is also known asMineralization.This process was carried out by some Saprophytes like Fungi andBacteria.Ammonia is also produced from volcanic eruptions and excretory products of Animals.4.Nitrification:The Bacteria which is involved in nitrification is known as Nitrifying bacteria.Ammonia is first converted to nitrites.Examples: Nitrosomonas,Nitrococcus.Nitrites are converted to nitratesExamples:Nitrobacter.5.Denitrification:Nitrates are converted into molecular nitrogen through Nitric oxide is known as Denitrification, in order to maintain the equilibrium of nitrogen in the atmosphere.Bacteria which are involved in denitrificationare known as denitrifying bacteria.Examples: Thiobacillusdenitrificans,Pseuodomonasdenitrificans and Micrococcusdenitrificans.Problems with increase of Nitrogen:Acid rain formation. Acidification of soil and lakes. Increase in death of plants.

Muscular contractions require energy from our bodies, this energy is in the form of a molecule called ATP. However the body has three generation systems which it uses to create ATP. In aerobic states, when oxygen is plentiful in the body, the three generation systems (Glycolysis, Krebs Cycle, and the Electron Transport Chain are able to operate. The difference between aerobic and anaerobic. Once your ATP demand exceeds the ability of the body to deliver oxygen to run these processes, you enter an anaerobic state, in which only Glycolysis can continue to operate. Once byproducts build up, lactic acid forces this anaerobic activity to a stop. Anaerobic means, without oxygen. Is the electron transport chain aerobic or anaerobic? It is aerobic is the krebs cycle aerobic or anaerobic? It is aerobic is glycolysis aerobic or anaerobic? It can be both

A sponge might not look like much, but these simple animals with no brain or ability to move have lived on Earth for hundreds of millions of years. They can hunt prey and spawn, and Jonathan demonstrates how in this fascinating segment about the biology of sponges! ********************************************************************** If you like Jonathan Bird's Blue World, don't forget to subscribe! You can buy some Blue World T-shirts & Swag! http://www.blueworldtv.com/shop You can join us on Facebook! https://www.facebook.com/BlueWorldTV Twitter https://twitter.com/BlueWorld_TV Instagram @blueworldtv Web: http://www.blueworldTV.com ********************************************************************** When people think of a sponge, they usually imagine something like this: a cleaning sponge for washing the dishes…or for washing the car. Cleaning sponges are synthetic these days, but they used to come from the ocean. Back in the days before we had synthetic sponges for housework, cleaning sponges did come from the ocean. They were harvested by hard-hat divers walking along the ocean floor in heavy weighted boots with a rake-like tool to pluck the sponges off the bottom. It was a dangerous and difficult job. Bagfuls of sponges were lifted to the boat above. Immediately, the crew set to work cleaning the sponges. Then they were hung to air dry. After days or weeks at sea, when the boat was full of sponges, they were taken to shore, where they were auctioned to the highest bidder. Finally they were trimmed, sorted and sold to the public. Natural sponges are still harvested in nearly the same way today, but the synthetic sponge has spared the lives of countless ocean sponges! While an ocean sponge looks something like a weird plant, it's actually an animal. In fact, sponges are among the simplest multi-cellular animals on Earth. They live on the bottom of the ocean, attached to a surface and never moving because they can't walk or swim. Some are quite colorful, while others are drab. They also come in all shapes and sizes. There are tube sponges, vase sponges, barrel sponges, rope sponges, encrusting sponges and many other types. Sponges live from the frigid waters of the arctic and Antarctic, to the tropics. On many coral reefs, sponges dominate the sea floor and the drop off. One of the most common sponges on coral reefs is the barrel sponge. Barrel sponges grow to epic proportions, getting larger than a person! Although sponges can't walk or swim, they can feed. They do it by filtering tiny plankton from the water. A sponge is covered with small pores, called ostia, which lead to a system of internal canals and eventually out to one or more larger holes, called oscula. Within the canals of the sponge, chambers are lined with specialized cells called choanocytes, or collar cells. The collar cells have a sticky, funnel shaped collar and a hairlike whip, called a flagellum. The collar cells serve two purposes. First, they beat their flagella back and forth like fans to move water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide. Second, the sticky collars of the collar cells pick up tiny bits of planktonic food brought in with the water. Sponges are very effective filter feeders, since they are able to capture and eat particles as small as bacteria as well as much larger particles. They might not look like they are doing much, but a simple demonstration shows how effectively sponges can pump water. On a reef in the Caribbean, I make a dive with a syringe filled with a non-toxic dye called fluorescein. By squirting it around the base of some sponges, we can observe how the water is moving by watching what the dye does. Within only seconds, the dye is pumped through the sponges along with the water. As you can see, a sponge is a pretty good water pump, and also a good strainer. Any plankton that goes in with the water, won't come back out through the osculum. Tube sponges are even more spectacular to observe. They pump the dye so furiously that they look like a collection of miniature smoke stacks! Since sponges can't get together to reproduce, they spawn in a way similar to coral. The sperm is released into the water column by the male sponge and finds its way to the female sponges, where fertilization occurs internally. Eventually, the planktonic larvae are released from the female sponge and float around in the water column as plankton for only a few days. They then settle down and start growing. Sponges don't have many predators. There is not much nutritional value in a sponge and they're hard to digest. Hence, very few animals can eat sponges. But something was clearly eating this sponge! A sea turtle is the culprit. Sea turtles are one of the principal predators of sponges, along with a few species of fish and some invertebrates like nudibranchs.

Paul Andersen explains the process of photosynthesis by which plants and algae can convert carbon dioxide into useable sugar. He begins with a brief description of the chloroplast. He describes the major pigments in a plant (like chlorophyll a and b). He then describes both the light reaction and the Calvin cycle. He finishes with a discussion of photorespiration and strategies for avoiding this problem evolved in CAM and C4 plants.

Here are some rainy day activities for you – they are Fraser’s top 3 indoor activities. 1. DECORATING COOKIES You’ll need icing sugar, a tiny bit of water, sprinkles or any candy to go on top, digestive biscuits (or any will work to be honest) 2. SORTING MONEY You’ll just need coins, and anti bacterial wash as money is soooo dirty. 3. DYING EASTER EGGS You’ll need about 20 drops of food colouring, a teaspoon of vinegar and warm water and obviously cups or bowls to put it all in. Sorry about the lost footage – argh – technology! Here is another video of us dying Easter Eggs: http://youtu.be/iaXS8s-lpfM Please don’t forget to tag me if you and your little one try any of these out xx S O C I A L M E D I A BLOG https://emilynorrisloves.blogspot.co.uk TWITTER https://twitter.com/EmilyNLoves INSTAGRAM http://instagram.com/mrsemilynorris FACEBOOK https://www.facebook.com/emilynorrisl...

In December 2014, Bio-Rad, a biotech company located in the Bay Area that makes and provides equipment for laboratories, spent three days in Julie Zedalis’ Advancement Placement (AP) Biology class filming students conducting Bio-Rad's new pGLO lab investigation. In addition to making equipment, Bio-Rad is involved in science education. The pGLO lab investigation is one of Bio-Rad’s trademark labs in which students explore how bacterial cells become resistant to antibiotics. The same plasmid that carries the gene for resistance to ampicillin also carries the gene for green fluorescent protein isolated from jellyfish. Thus, if the bacterial cells have been successfully transformed, they will be able to grow on media with ampicillin and glow green. The interaction among the students, and with Ms. Zedalis, is integral to the purpose of the pGLO video − to instruct teachers how to promote student-directed inquiry in their classrooms. The Bishop’s School was the only high school in the U.S. invited to participate in this project. Ms. Zedalis, who serves on the Bio-Rad educational advisory committee, is a co-chair of the College Board’s AP Biology Development Committee and involved with the redesign of the AP Biology program.

This dramatic video choreographed to powerful music introduces the viewer/student to the wonder and miracle of the cell division and cell cycle. It is designed as a motivational "trailer" to be shown by Biology, Biochemistry and Life Science teachers in middle and high school and college as a visual "Introduction" to this miracle of life. As a high school Biology teacher myself, I have found this video to truly inspire my students to want to learn more about the topic. Please rate this video and feel free to comment. If you like it, please help me spread the word by posting links on your media websites. The more students who can enjoy these dramatic videos, the better! To view all of my videos in Biology, Earth Science, and Astronomy, subscribe to my channel at: http://www.youtube.com/user/sfgregs?feature=mhum. I will be releasing new videos periodically. I wish to thank all the quality video and music producers whose postings enabled me to assemble this video for educational use. To best enjoy this video, turn up your speakers. The music is very powerful and dramatic! The music is "Pure Spirit of the Forest" from the movie, Avatar. I can customize this video to add your name or school name at the end credits, for a very modest fee. If interested, email me at "email@example.com" Until recently, you were able to download my videos for free from my other video storage site (vimeo.com). Recently, however, they began charging a significant membership fee to enable that feature, so I regret that downloading from there is no longer available. However, you can search for and obtain free download addons for your browser that will allow you to download my videos from either YouTube or Vimeo.
