Slide 7: What are some effects of gravity we can experience on Earth?

• Earth orbiting around the Sun

• Earth's atmosphere keeps us alive

• Tide

• Increased temperature of the atmosphere
• Seeing the position and phase of the Moon each day

Slide 10: ​ The Moon pulls on the Earth with a varying amount of ​ ​ (a)   across the Earth. The side of the Earth​ (b)   to the Moon is pulled on with a greater force than the side further away. This difference in force causes a (c)   on the Earth that results in low tides on the sides of the Earth that are (d)   from the Moon and (e)   tides on both the side facing the Moon and the side away from the Moon.

Slide 12: Organize these options into the right categories

Groups:

(a) High Tide

,

(b) Both

,

(c) Low Tide

• The lowest point in the tidal cycle in a day

• Caused by the Moon’s gravitational pull on the Earth

• Side of Earth toward or opposite the Moon

Slide 13: When the Moon, Sun and Earth are (a)   up together, we get a ​ (b)   tidal bulge. This is called a ​ (c)   Tide. The tidal effects from the Moon and Sun are (d)   together and so the tidal effect is larger.
