GPS: Global Positioning System
by Jeanne Sturm
Review by Danesha
People love to explore, that's why we need a GPS. Hey, do you know what GPS stands for? It stands for Global Positioning System. They use satellites and monitoring stations and receivers to tell where you are. Guess who came up with this? Our own government! Isn't that cool? The military used it, but soon it was released to the public. It's used by fishermen, hikers and all types of people. In the early days, people used the stars and the sun to tell where they were. Do you know how to use the sun to tell where you are? You can tell where you are by where the sun is in the sky!
I have a GPS in my mom's van! Now that I've read this, I loom at GPS differently! -Akiera

Danesha, the best part of this review is that I can hear your voice! Well done! And no, I don't think that I would be able to tell where I was just by using the sun. Thank goodness for GPS!!! <3, Mrs. Haas
