Your Age on Other Planets
In science class, you learned that the farther a planet is from the Sun, the longer its period of revolution. Every time Earth makes a trip around the Sun, you become one year older. How old would you be now if you lived on the other planets? Try this activity with your family members to find out!
Materials
