How does the moon make light? Or what actually does? The sun is actually making the light but the moon is in the way so the light bounces off its surface. That’s how the, “moon is making light” happens. If you still don’t understand use the handy slide show. I hope you like it!

Earth’s satellite

New Moon view in the skyFull Moon view in the sky

New Moon - The Moon's unilluminated side is facing the Earth. The Moon is not visible (except during a solar eclipse). Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. First Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. Waxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. Full Moon - The Moon's illuminated side is facing the Earth. The Moon appears to be completely illuminated by direct sunlight. Waning Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. Last Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. Waning Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing.

Triple Beam Balance

Even though that has nothing to do with energy that is called a triple beam balance When you put something on it you can measure how much it weighs by moving the grams until the point is on the line.

Argentine Ant Diagram Why Me?

That is a graduated cylinder. It is used to measure in milliliters.

How do we get energy???????

Helium Is used for floating balloons and is less dense than the atmosphere so it floats. WARNING: Helium is fatal if breathed. It is the second lightest element. It is named after Helios, a Greek work meaning sun.

The four elements of the Greek are fire, water, earth, and air.

Phases of Matter These are solid copper atoms in 1,083 Celsius. These are liquid copper atoms in 1, Celsius. These are gas copper atoms in 2,595 Celsius. These are solid water atoms in 0 Celsius. These are liquid water atoms in 1-99 Celsius.

As you know, stuff grows when it is heated up.

Waves Waves send stored energy through kinetic energy.

Water

Surface Tension Surface tension is an invisible layer of protection around the surface of the water. Soap is a thing that can break the surface tension.
