text: Though controversial among students, summer assignments have a very important role in students' summers, they ensure that students don't fall behind once they return to school in fall. It is important that these assignments remain teacher-designed as opposed to student designed because teachers understand what materials students must remember, they know how to structure assignments, and unlike students they make the assignments helpful instead of making it easy. It is important to remember how these assignments not only impact the individual student, but how they impact the entire class.Is the face on Mars an alien artifact of just a natural landform? So far we have no real proof that aliens even exist. Also in 1998 the JPL website revealed that it was just a natural landform and not made by aliens. Also NASA would be just as excited to reveal that another life form has been found, that wouldn't be a kept secret.
