1. Study Hall—Work on homework Sit in your assigned seat.

2. Warm Up: Bay of Fundy Time Lapse Video • http://www.youtube.com/watch?v=OP0cpXpw8yk • Watch the video and answer the following questions: • Do you think people who live here think about the tides each day? Give an example if you can

3. Worksheet • Take out your seasons worksheet from yesterday and lay it on your desk • I will be coming around during warm up to give you credit for completing it

4. Volunteers for Warm Up • We will learn that tides are caused by the gravitational pull of both the moon and sun • Some people who depend on the oceans are concerned with the tides • Tourism (whale tours) • Fisheries • Transportation (ferry boats)

5. Bay of Fundy Time Lapse Video • Watch the video again • This video covers 12 hours (it is just sped up really fast) • How many high tides and low tides do you think the Bay of Fundy experiences in 1 day (24 hours)

6. Where is the Bay of Fundy? • http://www.youtube.com/watch?v=qfhNjpu_IU4

7. ANNOUNCEMENTS • Today, Tuesday Feb 18 – Tides • Wednesday Feb 19– Eclipses • Thursday Feb 20 – Quiz (Earth, Sun, Tides, Seasons, Eclipses); then start next unit 6.E.1.2

8. Video • Discovery Ed: The Moon and Tides (stop at 3:00 minute mark)

10. SEASONS WORKSHEET • Get out your homework • We will review the questions together • Follow along as I project the worksheet onto the whiteboard • What did you notice about the different hemispheres?

11. New entry in Notebook: Tides Today we will be learning about the tides and why they happen.

12. WRITE IN NOTEBOOK TIDES: The movement of oceans and seas due to the gravitational pull of the moon and sun Tides are due to gravity! This ocean water movement creates = high tides (rise of water) and low tides (fall of water)

13. WRITE IN NOTEBOOK • Coastlines = 2 high tides and 2 low tides each day (24 hours) • Tides are predictable (we know when they will happen) • Tide Tables = list 2 high tides and 2 low tides for coastal regions each day

14. Tides tables for North Carolina • http://www.saltwatertides.com/dynamic.dir/ncarolinasites.html • http://www.saltwatertides.com/dynamic.dir/scarolinasites.html

15. Spring Tides • Spring Tides = extra high and very low tides • formed when the earth, sun and moon line up in a straight line • Straight line, think S = SPRING TIDES • happens every two weeks during a new moon or full moon.

16. Interactive Video for Spring Tides • http://ww2.valdosta.edu/~cbarnbau/astro_demos/tides/neap_sp.html

17. Neap Tides • Neap Tides= high and low tides with very little change • formed when the earth, sun and moon form a right angle (like a L shape) • Think “L” - ”M” - ”N” in the alphabet • L (Lowest) M (means) N (neap tides) • Neap tides happen during a quarter or three-quarter moon

18. Interactive Video for Neap Tides • http://ww2.valdosta.edu/~cbarnbau/astro_demos/tides/neap_sp.html

19. Let’s Draw • SPRING TIDES • STRAIGHT LINE MEANS SPRING TIDES • NEAP TIDES • LMN LOWEST MEANS NEAP TIDES

21. Tides Song http://www.youtube.com/watch?v=KFYf_it461s

22. Watching the Tides • http://science.kqed.org/quest/video/science-on-the-spot-watching-the-tides/
