Tides, Waves & Currents
Know that the ocean has tides (water level rises and falls twice a day, caused mainly by the Moon's gravity), waves (caused by wind), and currents (rivers of water flowing through the ocean that carry warmth and nutrients around the world)
Typical age: 7–9 years
“If your child noticed the water level changing at the beach during the day, could they explain that tides are caused by the Moon's pull, and that the ocean also has waves from wind and currents that flow like underwater rivers?”
