In this scene from the 2008 Masterpiece adaptation of Jane Austen's Sense and Sensibility, the Dashwood sisters and their mother first see their new home, Barton Cottage, a simple dwelling set against the tumultuous north Devon coast-and the viewer experiences it with them. As the camera swoops over the untamed sea, the cottage first appears large, then insignficant when set against the vast landscape. The Dashwood family, now very far away from the "civilized" world of society, is on its own. As we follow the family as they enter the cottage, each character's reaction-Mrs. Dashwood is overwhelmed, Marianne pronounces it "romantic," and Elinor is practical-reinforces what we already know about their personalities.

The romance between Edward and Elinor is, for many, the heart of Sense and Sensibility, and Edward's proposal serves as the climax of the 2008 Masterpiece adaptation of Jane Austen's Sense and Sensibility. From the moment Edward arrives at the cottage, there is a palpable sense of suspense. As the scene unfolds-Edward declares his love and Elinor accepts amidst tears of joy-the happiness that the characters experience is so real and powerful that we find ourselves cheering them on.

Students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. They do this by attempting to identify several different foods that have similar textures. For some of the attempts, students hold their noses and close their eyes, while for others they only close their eyes. After they have conducted the experiment, they create bar graphs showing the number of correct and incorrect identifications for the two different experimental conditions tested.
