What causes waves?
What are tides?
How does the ocean move?
Part 1 of the activity:Wave demonstration- place water in a pan with a fan going across it on low, change the speed to high- discuss what the students observe happening
Students will create a wave bottle. Have students draw their wave bottles in their notebooks. Have a wave bottle made to model for the group- what happens if detergent or cooking oil is added-use the teacher's model not the students' so theirs is not ruined. Discuss what happens to the wave.
Guiding Questions to ask during this part of the activity: How does the wave move? What does the movement remind you of? What happened once the cooking oil was added? How do you think this would effect the ocean water? The creatures in it?
Part 2 of activity:Tides- show students images of the Bay of Fundy and how drastic the tides are there, at least a 30 foot difference
Guiding Questions to ask during this part of the activity: what causes tides and what does high tide/low tide look like? How would tides make in difference in being able to develop resources at the coast?
Give written step bt step directions if needed
Shows pictures of waves and high/low tide with vocab words
