Using Everyday Materials to Teach Science
One of the commonly held ideas about teaching the sciences is that you cannot achieve much without expensive equipment. Certainly, it is wonderful to have microscopes, electrical apparatus, lots of chemicals models and charts. But a great deal of hands-on science can be done using simple, everyday materials. In this episode you will be introduced to learner-centered activities, which do not require expensive equipment. Teachers will be encouraged to get learners involved in the collection and housing of such material so that the learners develop a sense of ownership of THEIR science centre

What's Matter? - Crash Course Kids #3.1
Hey... what's matter? No no no, not what's THE matter. What's MATTER? In this episode of Crash Course Kids, Sabrina talks about what matter is and the three states of matter: Solid, Liquid, and Gas. She also does a quick experiment that you can do at home to prove that air is matter. This first series is based on 5th grade science. We're super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 5-PS1-1. Develop a model to describe that matter is made of particles too small to be seen. [Clarification Statement: Examples of evidence could include adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, and evaporating salt water.] [Assessment Boundary: Assessment does not include the atomic-scale mechanism of evaporation and condensation or defining the unseen particles.] Want to find Crash Course elsewhere on the internet?

Chemical Volcano and Fire Blizzard with Chromium Oxide!
Facebook: https://www.facebook.com/thoisoi2 Patreon: https://www.patreon.com/Thoisoi?ty=h Music: http://audiomicro.com Interesting chemical experiments: http://www.m.chemicum.com/ Hello everyone. Today we will conduct a reaction with chromium oxide 3. Chromium oxide will serve us as a catalyst. We will get the chromium oxide out of the reaction of the decomposition of ammonium dichromate. Do not attempt to repeat following experiment by yourself! For the reaction, we will take a metal cup and pour there a little, though nevermind, let's just empty the entire ammonium of dichromate. Next, we ignite the substance using a burner and then observe the beautiful decay of the substance. Well, the reaction has been completed now and we've got quite a lot of chromium oxide 3 as a result. The first reaction with it is going to be the catalytic oxidation of ammonia using chromium oxide 3. We will get ammonia gas from a Wurtz flask. To obtain it, we need a mixture of sodium hydroxide and ammonium nitrate. Now pour the reagents into the flask. Since ammonia is lighter than air, it is best to collect it from the bottom of the vessel. To start the reaction, we’ll add some water to the mixture. The reaction has started and now ammonia is entering the glass jar. After the jar is filled with ammonia, we need to heat up the chromium oxide 3. Light up the burner, get a bit of chromium oxide 3 into a spoon and heat it up. Now let’s add the retrieved red-hot chromium oxide into our jar. What did just happen during this reaction, you could wonder. Ammonia in the jar has reacted with oxygen. The catalyst for the reaction was chromium oxide 3. This reaction produces nitrogen oxide and water. For the next reaction let’s take a metal cup and pour there a small amount of chromium oxide. Place a piece of cotton wool soaked in ethyl alcohol onto the cup . Then, ignite the cotton. Now quickly sprinkle the cotton wool with chromium oxide. During this reaction, chromium oxide catalyzes the oxidation of ethanol to acetaldehyde. By the way, the smell of acetaldehyde is very much like a quick-drying super glue.

The Nucleus: Crash Course Chemistry #1
Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

Teaching a Science Lesson in Thailand
We are learning about materials. For this two-hour lesson, I had my fourth graders design and build contraptions to learn more about strength. Their goal was to build a contraption using only 10 pieces of papers, two strips of tape, and scissors. The contraption that can withhold the most weight (books) would be crowned first place. The students had so a lot of fun and were very engage! We then reflected on what variables contributed to the strength of a material. This was a great lesson!

SolidWorks 3D CAD Lesson Water in Tube Chemistry Geometry
This lesson develops the water required to fill the glass 16x100mm test tube. Water is a liquid and takes on the same shape the inside of its container. The inside diameter is 14mm. The Fillet radius is 7mm. In a laboratory, the working sample volume of water cannot be the same as the overall height of the test tube (the sample would spill during human or robotic intervention). Create the water as a separate part to fill the glass test tube. Determine the volume of water and its height from the top of the tube. This is a SolidWorks Lesson Plan and Tutorial developed by Marie Planchard for use by Students, Eductors and Teachers for Instruction and Demonstration to reinforce Education of SolidWorks 3D CAD Mechanical Engineering Design Software.

What is nanotechnology?
A short introduction to nanotechnology, and why you should care about it. The video dives into materials science and advanced materials, and looks at how designing and engineering substances from the atoms they're made of upward allows novel properties to be developed and used. It also looks at responsible innovation when it comes to grappling with the benefits as well as the health and environmental risks of nanoparticles and nanomaterials.

Just like all matter water has physical properties that can be measured and calculated. To find the mass of water you will need a beaker and a scale. First find the mass of the empty beaker. Next, fill up the beaker to your desired amount. Then use the scale to find the mass of the filled beaker. To find the mass of just the water, subtract the mass of the empty beaker from the full beaker. Our sample is 100 grams. The volume of water can be measured using a graduated cylinder. Our sample is 100ml. Density is calculated by dividing the mass by the volume. Plug in our measured mass at 100 grams and divide that by our measured volume of 100 ml. Water's density is 1 g/ml. Objects with a density greater than 1g/ml will sink when placed in water. Objects with a density less than one will float when placed in water. If a block has a density of 0.1g/cm3 it will float because it's density is less than 1. Another block with a density of 0.5g/cm3 will also float because its density is less than 1. Notice that more of the block is below the waterline. A block with a density of 0.9g/cm3 is more dense so more of the block will be below the waterline. We can see that as density increases more of the block is below the waterline. Scientists have discovered that the blocks density will tell us exactly where the block will come to rest. If the density is 0.1g/cm3 then 10% will be below the waterline. To calculate where a block will come to rest just convert the density to a percent. Density explains why ice floats. If you freeze water it expands. The black dots represent the atoms in water. No new atoms were are added to the water so because of the expansion there is more room between the atoms. Compared to the atoms in liquid water, the atoms in the ice are not as tightly packed together causing the ice to float. Try calculating density of ice for yourself. If you get a number less than one it will float. You can also predict how much of it will be below the waterline.

Why Deep Learning Works: Perspectives from Theoretical Chemistry, Charles Martin
We present new ideas which attempt to explain why Deep Learning works, taking lessons from Theoretical Chemistry, and integrating ideas from Protein Folding, Renormalization Group, and Quantum Chemistry. We address the idea that spin glasses make good models for Deep Learning, and discuss both the p-spherical spin glass models used by LeCun, and the spin-glass-of-minimal frustration, proposed by Wolynes for protein folding some 20 years ago. We argue that Deep Learning energy models resemble the energy models developed for protein folding, and, in contrast to the p-spin spherical models, suggest the energy landscape of a deep learning model should be ruggedly convex. We compare and contrast this to hypothesis to current suggestions as to why Deep Learning works. We show the relationship between RBMs and Variational Renormalization Group, and explain the importance in modeling neuro-dynamics. We then discuss how the RG transform can be used as a path to construct an Effective Hamiltonian for Deep Learning that would help illuminate why these models work so well.

Project Based Learning: Why, How, and Examples
Project based learning, PBL, is explained in full detail with examples and instructions for implementation. Teachers, educators, administrators, students, and more will develop a better understand of project based learning. This video is designed to help people get an deeper understanding than typical overview videos. The video begins with a description of why Project based learning is so important for students and in education in general. PBL can be used by teachers various disciplines. Some of the important reasons for using projects in your classroom such as allowing students to develop communication skills, utlilize 21st century life skills, become engage with the content, and share their projects with others in a public matter. The video also provides specific examples of projects that have been used by different teachers. The examples also include some of my favorite projects that I have created over the years. The projects are from different grade levels including algebra, social studies, and science classes. The video also presents the four different steps that will allow educators to implement project based learning. It begins with a driving question, an inquiry into the question, finding a solution, and presenting the material. This video is part of a google for education certified educator playlist where teachers look to earn google certificates and expand their career through professional development.

Chemical Bonding Introduction: Hydrogen Molecule, Covalent Bond & Noble Gases
Chemical bonding introduction video shows how covalent bond means 2 hydrogen atoms can stick together to form a hydrogen molecule, H2. The video also explains why helium cannot form bonds and hence is called a noble gas. Subscribe to watch more online chemistry courses & science videos: http://www.youtube.com/channel/UCiX8pAYWBppIbtUZTfGnRJw?sub_confirmation=1 About Atomic School: Atomic School supports the teaching of Atomic Theory to primary school & science students . We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program. Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class! The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival. It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences. Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth. About Ian Stuart (Email: ian.douglas.stuart@gmail.com): The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world. Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths. Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

Imagine a box filled with hydrogen atoms. Like billiard balls on a pool table, atoms actually move, and they do it in straight lines until they hit something … like another hydrogen atom. Oh! See that? They stuck together. They’re not separate hydrogen atoms any more, but a pair of hydrogen atoms moving together. There goes another pair. 4.1 When atoms join up like this, scientists call it a molecule. And they call the join between them a chemical bond. Here comes another hydrogen atom crashing into the hydrogen molecule. But this time it doesn’t stick. Instead it just bounces off. Hydrogen atoms bond once, and that’s it. They’re just like that. Pretty quickly all the hydrogen atoms will collide and pair off into molecules. They will keep hitting each other, but they'll just bounce off. Scientists like to have a shorthand way of writing this molecule thingi. Here’s one way to show it, with the hydrogen symbols joined by a stick to show the chemical bond between the atoms. Another way is to write H2, with the little 2 after the H and a bit lower. A number written this way is called a subscript. What do you think the 2 stands for? It counts the number of hydrogen atoms in the molecule. Easy, heh! So when we have a balloon filled with hydrogen gas, it really contains trillions of trillions of H2 molecules. Let's do another thought experiment. We'll go back to our box filled with hydrogen atoms, but this time put an oxygen atom in there too. When a hydrogen atom crashes into an oxygen atom, they stick together. But wait, when another hydrogen atom hits, it also sticks to the oxygen. What about a third hydrogen atom? No, that’s if for oxygen. It can only make 2 bonds and then it’s done.
