Dear Amy: I need help with a PowerPoint presentation for school. — Sarah, Lenexa, Kan.

Dear Sarah: PowerPoint presentations are relatively easy once you get the hang of them. Check out this site to learn the ins and outs of creating PowerPoint slides: www.actden.com/pp. First choose the layout you want and begin with the title slide. Once you learn how to make basic slides with text, you can figure out how to add images and sound. Good luck!

Dear Amy: Why do we have daylight-saving time? — Marcus, Cheyenne, Wyo.

Dear Marcus: Daylight-saving time, which begins on the first Sunday of April, was created to make the most of the daylight. The time change in the summer allows for an extra hour of daylight in the evening so that it gets darker later. This helps workers such as farmers, to maximize their productivity when they are working outside. For more details on daylight-saving time, visit http://webexhibits.org/daylightsaving/b.html.
