　　Flowering Plants

　　What arc the parts of a flower?

　　Flowers can have male parts and female parts. The female parts make eggs that

　　become seeds. The male parts make pollen. Pollen is a powdery material that is

　　needed by the eggs to make seeds. To make seeds, pollen and eggs must come

　　together. The wind, insects, and birds bring pollen to eggs. Many animals love

　　flowers\' bright colors. They also like a sugary liquid in flowers. This is

　　called nectar. While they drink nectar, pollen rubs off on their bodies. As they

　　move, some of this pollen gets delivered to the female flower parts.

　　Over time, the female parts turn into fruits that contain seeds. Animals

　　often eat the fruits and the seeds pass through their bodies as waste. The

　　animals do not know they are working for the plants by planting seeds as they

　　travel to different places! (147 words)

　　Finding the Direction and Location

　　How can you tell which direction? By day, look for the Sun. It is in the east

　　in the morning and the west in the afternoon. At night, use the Big Dipper to

　　help you find the North Star. It would be better to bring a compass because its

　　needle always points north.

　　How do you know how far you have gone? You could count every step. Each step

　　is about two feet. You’d better wear a pedometer which is a tool that counts

　　steps. If you know where you started, which direction you are heading, and how

　　far you have gone, you can use a good map to figure out exactly where you are.

　　Today there is a new way for travelers to figure out where they are. It is

　　the GPS. It has 24 satellites that orbit the earth and constantly broadcast their

　　positions. Someday you may carry a small receiver as you hike and use GPS to find

　　out if you are there yet! (167 words)
