How it worksMany ways! The sun’s light allows ocean animals to see. It serves as the source of energy for photosynthesis in producers. It produces heat to keep animals warm. It causes warm and cold air to mix and form wind. Tutu says the wind blows across the ocean to create waves.

Interesting FactEven though the sun is far away, light travels so quickly it only takes about eight minutes to reach Earth!

ExplainPlants need sunlight. They put sunlight together with water and carbon dioxide to make sugar, their food! Botanists call this process photosynthesis. Learn more about photosynthesis in U5.L2-Alive and Eating.

Doplantshavemouths?No! Plants do not have mouths. Instead, they take in sunlight through their leaves and produce (make) their own food. Animals have mouths to eat so they do not do photosynthesis. They depend on energy from eatingplantsorotheranimals.Rememberthefoodchain?Withoutplants, animals could not get energy, even with mouths!

Isithotterinthesunorshade?Sun! Energy travels from the sun to our planet in the form of heat energy and light energy. The energy from direct sunlight will heat what it touches, including water, land, and living things. If you stand in the shade, the heat from the sun is being blocked by the thing making the shade.

Dotemperatureschangebetweennightandday?Yes! During the day, temperatures are hotter. Heat energy from the sun warms Earth’s surface and everything on it. At night, Earth spins away from the sun so temperatures drop.

Interesting FactThe temperature in the middle of the sun is over 60 million degrees Fahrenheit. No living creature or plant could survive that temperature!

How it worksNo! Ocean waves do not actually carry water across the ocean. Instead, they move energy through water. Uncle says to think of your wave. The sun’s heat energy caused the wind to blow. The wind caused a wave to form. The energy in the wave passed from water molecule to water molecule. The energy moved from one end of the line to the other, but you (water) did not move! Your arms moving up and down caused the wave. Ocean waves work the same way.
