To share with the entire class:

• DVDs of October Sky and Harry Potter and the Sorcerer's Stone (borrow from your school or public library so you can show students specific portions; if not available, describe the scenes, since most students are familiar with the movies and will be able to recall the scenes and describe them more fully to other classmates)
• DVD player and screen/monitor, to show the class the movie clips
• 3 stopwatches
