Mary Celeste was found abandoned in 1872. The ship had left New York on November 5, 1872. The crew of another ship, the Dei Gratia, observed that she was floating aimlessly near the coast of Portugal. Members of the Dei Gratia crew boarded her on December 4 and found no people and no sign of violence. The captain and his family, the crew, and a lifeboat and navigation instruments were missing, but the ship and cargo were in excellent shape. The mystery of the Mary Celeste has yet to be solved. Children could read The Mary Celeste: An Unsolved Mystery from History by Jane Yolen and Heidi E. Y. Stemple. Older children could read more at: Mary Celeste.

Idea: Children could dig up some soil and look for plant remains and animals. They could also investigate how to compost.

Pathfinder was launched toward Mars in 1996. The craft traveled for 211 days and 309 million miles to reach the surface of Mars on July 4, 1997. A small rover named Sojourner (named after Sojourner Truth) traveled about the surface and analyzed rocks and the surface of the planet. The two vehicles (both significantly outliving scientific estimates) sent back 2.3 billion bits of data before transmissions stopped on September 27, 1997. Children can view some of the images of Mars at: Pathfinder.
