Show me what you know about the sea. Learners answer 10 questions about marine biology. The questions range from what evidence points to the origin of life to the biggest threat to oceans.

A marine environment covers the majority of the earth but is arguably the least understood. Teach young scientists about the characteristics of oceans and ocean species using an interactive online lesson. The in-person or remote learning...

For this black holes and tidal forces worksheet, learners solve 5 problems in which they find the tidal acceleration and answer questions about spaghettification.

The Woods Hole Oceanographic Institute provides an in-depth but easy to read article on the role of the moon and the sun in respect to tides.

Did you know the rising and falling of the sea level is caused by the gravity of the Moon and the Sun? Kids learn about ocean tides including tidal currents and types of tides on this site.

An excellent and thorough answer to the often asked question about high tide "bulges" on the side of Earth facing away from the Moon or Sun.

Even great scientists make mistakes! This illustrated essay from the NOVA Web site looks at Galileo's theory of the tides, which, while well thought out, was wrong.
