Easter is a celebration that happens once a year, on the first Sunday after the first full moon after the vernal equinox. Easter usually falls in March or April. Easter celebrates the resurrection of Jesus Christ, although modern familes who aren't practicing Christians will use the event to hold a hunt for chocolate or plain Easter eggs with their children.

Echinacea, also called the purple coneflower, is a member of the daisy family. Echinacea has been known for a long time to possess medicinal properties that help ward off the effects of the common cold. Chewing the root of the plant seems to boost your immune system, helping you get better faster if you are sick.
An echo is reflected sound. You get echos most often in enclosed spaces with hard walls, like an empty room with wooden floors, or the inside of a large concrete pipe like in the picture. If you make a noise in a place like this, the noise you make sounds like it is being repeated back at you again and again, getting quieter each time.
