Surf's up, big kahunas! How do surfers know when the big waves will appear? They use science! Over the course of five days, dive in to the inner workings of tidal waves and learn to predict sea levels with the moon as your guide.

Students examine the topics of ocean waves, currents, and tides. They locate and label ocean currents on a world map, conduct experiments, analyze key vocabulary, view demonstrations and record the data, and complete handouts.

Students complete a unit of lessons on our solar system, its stars, and astronomers. They record information in a space journal, design constellations, define key vocabulary, observe the phases of the moon, and create a group planet...

Students explore the main concepts of astronomy through the eleven lessons of this unit. The past, present, and future methods of studying the science are examined in this unit.

This lesson explains how the moon affects tides on Earth and about the different types of tides.

A short description of how Cavendish measured the value of G - the universal gravitation constant and supported Newton's theory. Illustrated.

By the end of this section, you will be able to explain Earth's gravitational force, describe the gravitational effect of the Moon on Earth, discuss weightlessness in space, and understand the Cavendish experiment.

In the following interactive students will explain Earth's gravitational force and describe the gravitational effect of the Moon on Earth. They will discuss weightlessness in space and examine the Cavendish experiment.
