1. Go to http://bit.ly/TidesStationLAb

2. Explore the animation and then answer the questions

When the Sun, Moon, and Earth make an L-shape, this is called a neap tide. During the neap tide, the oceans will experience the least difference between high tide and low tide.

1. What do you notice about the bulge as the Moon orbits Earth?

The blue line oval around the Earth represents the Earth’s oceans.

1. What Moon phases are present during a spring tide?

2. What Moon phases are present during a neap tide?

When the Sun, Moon, and Earth are in a straight line, this is called a spring tide. During the spring tide, the oceans will experience the greatest difference between high tide and low tide.

One member of the group will read the task cards in order. The group will be responsible for completing each of the tasks that are being read.

Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.

1. When the Sun, Earth, and Moon form a 90 degree angle this is called a neap tide.

The moon can also be on the opposite side of the Earth in this model and a neap tide will still occur.

Answer the following questions on your lab sheet.

1. What moon phases are present during the spring tide?

2. What moon phases are present during the neap tide?

3. What force causes the tides?

Setup a model using the Sun and Earth using the image below.

1. What season would it be in the northern hemisphere?

2. What season would it be in the southern hemisphere?

Sun E

Revolve the Earth around the Sun (counter-clockwise) until you get to the position in the image below. Keep the axis pointed in the same direction the entire time.
