Jelly bean stem activity

Jelly beans are thought to have been invented by William Schrafft, a Boston candy maker. Schrafft is believed to have encouraged families to send his jelly beans to soldiers during the Civil War. By the 19th century, jelly beans were a common household name. Jelly beans were the first candy sold by weight instead of by the piece in the United States.

Science experiment with jelly beans

  • Invite kids to arrange the jelly beans in a color pattern around the edge of a paper plate (kids can use ALL colors in the bag to pattern with or choose only 2-3 jelly bean colors if desired).
  • After the jelly beans are arranged (this is a great fine motor activity for younger kids), choose one of the liquids to begin. Pour the liquid slowly onto the center of the paper plate and observe closely as the liquid disperses.
  • Start the timer as soon as all the liquid is poured onto the paper plate.
  • Invite kids to photograph the jelly beans as the colors begin to dissolve and throughout the remainder of the exploration.
