Can you make up a sentence
The moon orbits the earth anti-clockwise and takes approximately 28 days. The moon spins once on its axis every time it orbits earth. This means that we only see one side of the moon. The moon has different phases depending on where it is in it’s orbit. At different times the moon appears to be different shapes because the sun light up different parts of the moon as it moves around the earth. The moons gravity causes high and low tides
