RACHEL: This phenom was sent in by David G. of Columbus, Ohio. Here's a cup with two holes in it. See how the water is pouring out of the holes?
KALEIGH: If we drop the cup what do you think will happen to the water coming out of the holes while the cup falls? Will the water come out of the holes faster? Will the water come out of the top of the cup? Or will the water stop pouring out of the cup altogether? Make a prediction. Okay, let's see if you were right.
RACHEL: Okay, here we go.
RACHEL: Did you see how the water stopped pouring out of the holes? Was your prediction right? I'll explain. When I hold the cup the water pours out of the holes because of gravity. But when the water and the cup fall together, the water doesn't need to pour out of the holes to get down. It just falls with the cup. This is probably hard to see on TV, so try it at home.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
