Video1


 * Too Schematic Christina.... What about the explanations they were not clear. 5pts**

1. You are about to watch a video called "Dr. Quantum - Double slit experiment". What do you think it will be about?

Any physics experiment about two grooves. I imagine that he will make __cross__ __somethinkg__ ** something cross ** __into__ ** through **those slits.  = = 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.**__

slit
 / slɪt /  [ slit ]   verb, slit, slit·ting, noun

–verb (used with object) 1. to cut apart or open along a line; make a long cut, fissure, or opening in. 2. to cut or rend into strips; split.

–noun 3. a straight, narrow cut, opening, or aperture." from http://dictionary.reference.com/browse/silt

It can be noun or verb but I think that __quamtum__ ** Dr. Quantum ** refers to the name
 * Good **

3. Mention five words you think you will find in the video

1) Slit 2) Physics 3) Cross 4) Division 5) Result ** Good ** **During Video 1****. Are there any of the words you mentioned in the previous question in the video?**

Yes, there is "Slit " ** Good ** We need big particles of ma** t **ter, water, a source of light, a wall with two slits and a screen to see the result. there are six steps
 * 2. What's the experiment about? Describe it.**
 * a.What does he need to do the experiment?
 * b.How many steps does it have?

1) big particles, a slit: it produce** s ** a band of particles. 2) big particles, two slits: it produce** s ** two bands of particles. 3) waves of water, a slit: it produce** s ** the same number of not intersected waves. 4) waves of water, two slits: it produce __tow__ ** two **groups of intersected waves of water. 5) electrons, a slit: it produce** s ** a band. 6) electrons, two slits: it produce** s ** a group of bands.
 * c.What happens in each step?

electrons
 * d. What is the third element Dr. Quantum uses?

**3. What happens with balls and one slit? And with two slits?** 1) big particles, a slit: it produce** s ** a band of particles. 2) big particles, two slits: it produce** s ** two bands of particles.

**4. What about waves?** 3) waves of water, a slit: it produce** s ** the same number of not intersected waves. 4) waves of water, two slits: it produce** s ** tow groups of intersected waves of water.

**5. What happens with electrons** 5) electrons, a slit: it produce** s ** a band. 6) electrons, two slits: it produce** s ** a group of bands.

**6. What explanation does Dr. Quantum give?** He say** s ** that the electrons (light) perform as a wave. He explain** s ** that the bands are the representation of the intersection of the light waves.
