  Reading comprehension for grade 4 involves understanding longer and more detailed texts. Students analyze the text for main ideas, supporting details, cause and effect, and inferences. Here’s an example: Passage: The sun was setting as Mia and her brother, Alex, reached the top of the hill. They had been hiking all afternoon, and now they could see the entire valley below. The trees looked like tiny green dots, and the river sparkled in the fading sunlight. “It was worth the climb,” said Alex, smiling. Mia nodded, feeling proud of their effort.

For example, time dilation*, a consequence of the Theory of Relativity (for particles that move almost with the speed of light) or the fact that time slows down in the presence of strong gravitational field, are real, verified facts. Thus, continuous forward time-travel is perfectly OK. (By continuous, mean there should be no gaps in the accounting of time.) What is problematic is travelling backwards in timeand this is what usually is meant by `time-travel' in popular movies and books. This is not allowed by laws of physics as we know them now, since these laws have "causality" built into them. Causality means that the cause happens before the effect, and not vice versaFor example, a glass breaks after it falls downit does not fall down after it breaks; the falling comes first. Thus, causa...
