- Synopsis
- Sometimes scientists need to observe objects closely. Certain tools can help them observe details they might not be able to see with just their eyes. A hand lens makes things look larger than they are. It magnifies them. Hold the lens a few centimeters in front of your eye. Then move the object closer to the lens until you can see it clearly. Never let the lens touch your eye. Never use it to look at the sun!
