9) The Chesapeake Bay, a large estuary that lines the coast of Virginia and Maryland, was formed 35 million years ago.
The landscape was created by a meteor impact event around 35 million years ago and the crater filled with water
millions of years later as sea levels rose. Which of these pieces of evidence best supports the theory that a meteor
impact event formed the Chesapeake Bay area?
A)
A layer of reddish iron deposits exist in layers older than 35 million years.
B)
A layer of iridium and shocked quartz is present in sedimentary layers from
35 million years ago
C)
Uranium in the sediment layers older than 35 million years are emitting
low levels of radiation
D)
Marine fossils present prior to 35 million years ago are not found in
sediment layers more recent than that

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
