Zooming into an Atom (Annotated)
 
00:24
On September 14, 2015, LIGO became the first instrument to detect gravitational waves on Earth. When two black holes, each about 30 times more massive than our sun merged, they generated gravitational waves—ripples in space and time. More than a billion years later, those waves reached LIGO's detectors, causing the distance between its mirrors—separated by 4 kilometers—to change by roughly 1/1000th the diameter of a proton. This animation zooms in on the proton of a hydrogen atom. The movement of the proton shows the tiny changes measured by LIGO. Image credit: LIGO/T. Pyle
Yogurt under a Microscope [40x 100x 400x 800x 2000x] Bacteria SEEN!
 
15:39
In this lab we see bacteria in yogurt under a microscope. Material: -yogurt -container -water -high power microscope Procedure - mix yogurt with a little bit of wate (2 part water). - Prepare slide -WAtch under high level (aprox. 1000x) Yogurt is a product of fermentation in milk by bacteria, that is why we see these bacterias, because they keep -producing- yogurt from the milk. The bacteria take the lactose and turn it into lactic acid in fermentation which give the characteristics to yogurt. Common bacterias found are baccili and cocci. Any suggestion on what to see next, comment!
