Lesson: ESM 14_ Tides Review
OBJECTIVES: By the end of today’s lesson, you will be able to…
□ SWBAT demonstrate mastery of all tides aims
DO NOW
1. _____ Neap Tide
A. When water in the ocean is at its
highest point.
2. _____ High Tide
3. _____ Gravity
4. _____ Spring Tide
5. _____ Low Tide
B. The type of tide that occurs when
the Sun, Earth, and moon form a
right angle. These tides are not
very strong.
C. the force of attraction between all
masses in the universe. The
larger the mass of an object, the
more gravitational pull it will have.
This is why all of the planets orbit
the Sun.
6. _____ Tidal Range
D. The difference between the
highest level and lowest level of
the ocean.
E. When water in the ocean is at its
lowest point.
F. The strongest type of tides which
occurs when the Sun, Earth, and
Moon are in a straight line.
