Periodic Table

1.
Before we watched the film about the elements I knew a few things about the periodic table. I knew many of the elements were metals and were grouped by what type of element it was categorised by. I knew the Periodic Table was also put together by a scientists named Mendeleev. I also knew the numbers on the table represented each elements atomic number.
2. 
I learned a few things out of the film like how protons and neutrons work and why they go together. What I think was the coolest thing I learned was how adding a electron to the atom will force another electron out triggering a domino effect to all the other atoms. I also learned how many of the elements on the table are in the basic items we use. I would've never thought samarium was in regular magnets.
3.
With everything I learned from the film I'd like to see if we can create even more elements. I know we have found new elements but they only are stable for 10 seconds. I would also like to see if we could enhance the elements and find new ways to use them for our every day life. It would also be useful to find new energy in elements.

Alternative Energy

     Alternative energy is well another source of energy. Fossil fuels are also a source of energy but many fuels pollute and contaminate the air. The difference between the two Alternative energy and Fossil fuels is that one is good for the earth and is renewable. Alternative energy is in the form of water, wind, and solar. The alternative energy is another solution of getting energy without causing harm to the earth. The cool thing about alternative energy is that it can be reused and it also can also change forms of energy. Fossil fuels are not renewable once they are used you cannot reuse them they are gone. Okay so say I burn a piece of coal and it powers this generator I have, but also say I have have water and solar energy working together to create steam and I power the generator with steam. Which one do you think is better for the Earth? The steam powered generator is better because it didn't pollute the earth. What are your thoughts on alternative energy?

Snell's Window





Snell's window is a phenomenon in which a viewer underwater sees the surface through a cone of light. The cone of light is created by refraction as the light hits the water. When the light hits the water it bends outward because it is refracted off the medium which would be the water. The light must hit at a angle to refract and create the cone. If the light comes in at no angle the light will not bend. The largest angle you can create is a 90°angle if it is above it will only be paralleling the water or medium. Snell's window is possible because of Snell's Law of Refraction. Refraction is when light hits a material and goes through it, but when it goes through it the light bends. The bending light creates the cone of light you see when you witness Snell's Window. Snell's Window is a cool science related thing that most people wouldn't think science would have something to do behind the creation of Snell's window.
