Video 1: Dr. Quantum - Double slit experiment ** 1. You are about to watch a video called "Dr. Quantum - Double slit experiment". What do you think it will be about?
 * Good 7pts
 * Before watching the video, answer the following questions: **

I think that the video is about an experiment with matter.

2. Go to a dictionary and copy the definition of "slit". Is it a noun, a verb? Is it is both? Mention all definitions. **Please acknowledge the source. ** //n. // A long, straight, narrow cut or opening. //tr.v. // **slit**, **slit·ting**, **slits** It can refer to a verb or to a noun as we can see in the phrases. Source: [] 3. Mention five words you think you will find in the video Matter, Quantum, slit, experiment, dimension. Please click on the following link to watch the video and answer: [] All the words were mentioned except __dimension__. <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; line-height: 115%;">The experiment treats about how the waves and particles differ when was fired by one slit. The experiment is done in various stages with different types of matter like marbles and water waves. <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">a.What does he need to do the experiment? <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 12pt; line-height: 115%;">He needs electrons, marble balls, a metal board one with one slit and another with two slits, water, and a machine that shoots electrons. <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">b.How many steps does it have? <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; line-height: 115%;">The experiment is done in 6 steps, in which 2 steps for each element.
 * <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 12pt;">1. **<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 12pt;">To make a slit or slits in.
 * <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 12pt;">2. **<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 12pt;">To cut lengthwise into strips; split.
 * <span style="color: #0d17f2; font-family: 'Palatino Linotype','serif'; font-size: 17.5pt;">During and after watching the video, please answer **
 * <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">1. Are there any of the words you mentioned in the previous question in the video? **
 * <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">2. What's the experiment about? Describe it. **

<span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">**//c.What happens in each step?//**
<span style="font-family: 'Arial','sans-serif'; font-size: 12pt; line-height: 115%;">In the first step he shoots marbles through one slit. In the second step now he shoots marbles through two slits. Later he observes how the waves through one and two slits are behaving and then he shoots electrons through one and two slits but with a different machine. <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">d. What is the third element Dr. Quantum uses? <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; line-height: 115%;">The third element that he uses is electrons. <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; line-height: 115%;">Dr. Quantum says that he hasn’t explication of why the electrons act differently while being observed and that the science haven´t answers to this yet.
 * <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">3. What happens with balls and one slit? ****<span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">And with two slits? **
 * <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; font-weight: normal; line-height: 115%;">With one slit when the balls are shot they create a vertical line and with two slits the balls create two vertical lines. **
 * <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">4. What about waves? **
 * <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; font-weight: normal; line-height: 115%;">With one slit the waves have more intensity forming a vertical line and with two slits the waves create an interference pattern. **
 * <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">5. What happens with electrons **
 * <span style="font-family: 'Arial','sans-serif'; font-size: 12pt; font-weight: normal; line-height: 115%;">With electrons something similar happens, with one slit electrons form a vertical line as in the others cases, with two slits electrons form an interference pattern as in the case of the waves. **
 * <span style="color: #056ef0; font-family: 'Palatino Linotype','serif'; font-size: 13pt; line-height: 115%;">6. What explanation does Dr. Quantum give? **
