Copy the day’s Learning Targets:
I can explain the effect of gravity on Earth
I can explain how tides work
I can create a line graph
Answer the following question (please copy the question)
If you are sitting on the beach does the position of the water ever move?

2. Mini Lesson
Gravity: force of attraction between all objects in the universe
The one gravitational force we feel the most is the Earth’s
How much gravity object A exerts object B depends on two things:
Mass of object A
Distance between object A and object B

3. Tides
The moon has gravity, but not enough to pull anything on the Earth but WATER
You get tides because of the Moon’s gravity

4. Tides
Tide: regular change in the level of the Earth’s oceans; there are 2 highs and 2 lows each day
High tide: when the tide is highest up on the beach
Low tide: when the tide is lowest down

6. Tides Spring tide: Tide that is higher or lower than a normal tide
Neap tide: Tide that is not as high and not as low as a normal tide.
