  • Push toothpicks into the side of a potato and suspend it in a glass of water. Students will be able to observe the formation of stems, leaves and roots.

By using archeological evidence and locating where wild relatives of certain food crops still grow, scientists have been able to estimate where these crops originated. Have students use the library to investigate the places of origin of some common foods.
