It's the year 2500. You live in outer space on a space station. One day, you watch as two spaceships approach each other and accidentally smash into one another and crash enough that they explode. What would you see and what would you hear? What is the scientific explanation for what you can/cannot observe in outer space?
Tarik puts his head down on a desk after he's done taking his quiz. When Mahi (who's sitting next to Tarik) goes to stand up to get a tissue, his desk accidentally bumps into Tarik's desk making a small noise. Tarik jerks his head off the table and when the teacher comes over to see to the disruption, he says that the bumping sounded REALLY LOUD when his head was down. How could you use science to expain why the noise was louder to Tarik, with his head on the table, than it was to the other students that did NOT have their heads down. (hint: assume proximity--how close or far students were--to Mahi does not matter)

Rocio and Maria want to start a garden for upper school. Dr. Menard gives them a bunch of dirt, but they need to move it to a different location. What simple machine could help make their task easier and why? Be specific about the scientific name of the simple machine as well as the object name in real life. Please include an explanation for how that simple machine works.
