The Relation of the Sun Moon and Stars to Us Science Project Idea
 Although so far away, the sun and moon exert a powerful influence upon everything that happens on the earth. This influence has been mentioned in considering the source of energy of food, coal, and wood, and the energy of water power.
Then too, the sun, moon, and stars, although so distant, have always been of the greatest interest to the inhabitants of the earth. The earliest speculations concerning things of Nature have been concerned with these heavenly bodies. We know now that much that was fanciful and erroneous crept into their ideas of these bodies; but we, just as our distant ancestors were, are interested in the wonders of the heavens. We, however, are not satisfied with fanciful imagination but want to know the truth Understanding Tides Science Project Idea We shall begin with one of the very evident ways in which the earth is affected by the nearest of these heavenly bodies, the moon. A study of the tides may give us some hints as to the relationship between the earth and other heavenly bodies and of the relation of these to one another.
 If you live near the seashore or have ever visited it you know something about tides. Let us first get together our observations concerning tides. How many tides a day? Does high tide occur at the same time every day? If not, does it occur earlier or later each day? How much higher is the water at high tide than at low tide? Are there any times when the tide is especially high ? To find out the cause of tides it is evident that we must be able to solve the following problems:
 What causes the rising of the water? Why the water comes up twice a day? Why high tide is a little later each day? Why, at times, there are especially high tides?
