Once upon a time, there were four friends named Lily, Max, Ava, and Ben. They were all in the third grade and loved science. They would spend hours in the school library reading books about space, dinosaurs, and inventions. One day, while they were working on a science project, they accidentally created a time machine!

Excited and curious, the friends decided to take a trip back in time. They set the time machine to the year 1776 and landed in the middle of the American Revolution. They saw soldiers fighting and cannons firing. It was like nothing they had ever seen before!

As they explored the past, they also learned valuable lessons. They learned about the importance of freedom and standing up for what you believe in. They also learned about the sacrifices people made for their country.

Next, they traveled to ancient Egypt and saw the magnificent pyramids being built. They even got to meet Cleopatra, the famous queen. They learned about the rich history and culture of Egypt and how advanced their civilization was.

Their next stop was the medieval times where they met knights and princesses. They learned about chivalry and bravery, and even got to attend a royal feast. They also learned about the importance of treating others with kindness and respect.

Finally, they traveled to the future and saw all the amazing inventions and technology. They were amazed by how much the world had changed and how much more there was to discover.

After their exciting adventures, the friends returned to the present time. They were grateful for the experience and all the lessons they had learned. They promised to always use their knowledge for good and to continue exploring the wonders of science.

From that day on, Lily, Max, Ava, and Ben were known as the time travelers. They couldn't wait to see where their next adventure would take them! The end.
