Relationship between Earth, Sun and Moon

As The Earth Turns The rotation of the earth causes a predictable change … What is the result? Hint? The side of earth facing the sun experiences day and the side not facing the sun experiences night. This cycle occurs every 24 hours.

As the Earth Travels The revolution of the earth causes a predictable change … What is the result? Hint? This cycle takes 365 days What causes the earth to experience seasons? Let’s find out by conducting a lab investigation! Reasons for the Seasons In this lab, you will use an Earth-sun model to make observations about factors that contribute to the seasons. Problem: What effect does the tilt of Earth’s axis have on the heat and light received by Earth as it revolves around the sun?

As the Sun and Moon Pull The rotation and revolution of the moon around the earth and the earth around the sun causes a predictable change….. What is the result? Hint? Tides are caused by the gravitational pull of both the sun and the moon.

As Gravity Pulls What causes the tides to be high and low? Let’s look at the animation again. Keep these questions in mind: What do you notice about the positions of the sun and moon during the high and low tides? Which seems to have more of an effect, the sun or the moon? Don’t forget to look at the key/legend at the bottom.

As Water Moves Let’s Find Out why there are bulges of water.

As the Bulge Goes Let’s Find Out! why the water bulges on both sides of the earth. Centripetal force and rotational inertia Now THOSE are science terms! You don’t have to remember those terms, but they are cool science words! Let’s do a demonstration that will show you what happens to the water – watch what happens to the ribbon!

Round and Round They Go Are there other predictable changes from the motions of the sun, earth and moon? Hint? Eclipses! Another hint? Phases of the moon!

So What Do We Need To Know? The rotation of the earth causes ….. The revolution of the earth causes …. The tilt of the earth’s axis causes uneven heating of the earth, which causes …. The gravitational pull of the sun and moon cause …. The moon blocking the sun or the earth blocking the moon causes …. The relative position of the earth, sun and moon result in ….
