Procedure Access the virtual lab and complete the experiments. Part One (Flame Test): 1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame: Barium-green Calcium-red Sodium-yellow Rubidium-purple Potassium-blue Lithium-pink 2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.: Unknown 1-yellow. I think it is Sodium because

Hypothesis Hypothesis is a preliminary assumption or a tentative explanation that accounts for a set of facts‚ taken to be true for the purpose of investigation and testing; a theory. In this research paper‚ we are trying to figure out what are the probable causes of Math anxiety as well as the possible solutions regarding this matter. We came up with the following: 1. Teacher Factor This simply means that a teacher has an effect on how a student grows or understands Math itself. There are times

Albert Einstein’s brain was different than yours or mine. The Great Physicist Albert Einstein may have been brilliant for biological reasons. It is estimated that someone with Einstein’s cognitive powers emerges only 500 years or so‚ but with the capability to clone humans on the horizon‚ perhaps within our lifetime‚ the technical ability to clone even an army of Einsteins is truly in the realm of science fact‚ and not science fantasy. So‚ what made Einstein different than you and I? When

Why do darker colors absorb more heat than lighter Colors? Have you ever wondered why on a hot summer day you would be wearing a black or dark blue t-shirt and in like 5 min you’ll already be sweating and it would be really hot while your friends that are wearing white or yellow t-shirts are all ok and don’t seem affected by the heat. Have you ever thought what might cause this to happen? Well the color of our clothes is determined by a chemical dye that is added to the cloth at the factory

Casino Royale Opening Sequence Analysis. Casino Royale begins with a pre-credit sequence that gives the audience a vague insight into the story of the film‚ that is about to unravel. While most Bond movies start with the trademark gun barrel sequence‚ Casino Royale was the first Bond movie to start with a pre-credit sequence that tied into the gun barrel sequence. Casino Royale also does not incorporate female figures in the opening credits and instead uses the James Bond character as the central

What is light produced‚ reflected and refracted into visible light? Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The definition of produced visible light means when the electromagnets radiation meets the human eye. The first example of produced is a glow stick because it produces its own light . Another

English 2.9 Internal “Highly recommended” Text 2; movie Title; Skyfall Director; Sam Mendes The inevitability of time‚ don’t you think? When my family finally dragged me along to see this movie‚ I could not stop talking about it for weeks after‚ and even now it is one of my favourite movies ever. Before seeing it‚ I was extremely hesitant. Being a huge fan of the Bond franchise itself as well as past Bond actors‚ this could have been a huge let down. Skyfall was the first Bond movie

Cami Petrides Mrs. Babich Algebra Period 4 April 1‚ 2014 Extra Credit Project 12. When you flip a light switch‚ the light seems to come on almost immediately‚ giving the impression that the electrons in the wiring move very rapidly. Part A: In reality‚ the individual electrons in a wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the -4th meters per second. How long does it take an electron moving at that speed to travel a wire 1.0

1. When a monochromatic point source of light is at a distance of 0.2 m from a photoelectric cell‚ the cut off voltage and the saturation current are respectively 0.6 volt and 18.0 mA. If the same source is placed 0.6 m away from the photoelectric cell‚ then find (a) the stopping potential (b) the saturation current 2. 663 mW of light from a 540 nm source is incident on the surface of a metal. If only 1 of each 5 × 109 incident photons is absorbed and causes an electron to be ejected from the
