Flash Interactives for Seasons and Lunar Phases

The Earth-Moon-Sun system... what a joy to behold! It's a little hard to understand at first, but these interactive flash simulations make it a whole lot easier. Say thanks to McGraw-Hill.

"Thank McGraw-Hill"

That's nice, children. :-)

Lunar Phases

Earth Seasons

Tides!

Here it is, 7th grade:

Tides Lesson
Questions to answer - before explanations:

1. At which phase (or phases) of the moon is the high tide at the highest point?

2. At which phase (or phases) of the moon is the high tide at its lowest point?

3. If the sun, earth, and moon all pull on each other because of gravity, try to explain why the shape of the tides changes over time.


Questions to answer - after explanations:

1. Why does the height of the tides change as the moon travels around the earth?

2. If it is neap tide, and you are at the beach at low tide, when the sun is in the sky, about what time is it? (go here for a hint about times.)

PhET - Physics Education Technology

For students who have seen the "particles in a box" simulation in class (it requires you to enable Java in your web browser), you can find that and many more at the PhET web site here:

You can also do the "particles in a box" simulation in French language if you download the application from this link:
