Children can save our planet in the name of science while having a great time at the "Kid Science: The Island of the Elements" exhibit at the Franklin Institute.

The exhibit takes kids ages 5 to 8 through a tale that teaches the elements of science - light, water, earth, and air.

On their journey across "The Island of the Elements," children will meet the "Power Keepers." To save the planet, the children must learn and perform the jobs of the Power Keepers in a quest to stop Lord Chaos and keep the island in balance with nature.

While in the exhibit, children can try activities including the Mirror Maze, Shape Shifter, Laser Maze, and Shadow Puzzle. They can also work with PVC piping in the Make a Fountain area to devise a water-delivery system.

"Kid Science: The Island of the Elements" is an ongoing exhibit at the Franklin Institute, 222 N. 20th St. Hours are 9:30 a.m. to 5 p.m. daily.
