=Week 4 Ocean Odyssey: Coral Reefs=

 

**Goals:**
Go over Coral Reefs, who lives there, what the environment's like, what is the largest coral reef, share photos of Great Barrier Reef from outerspace. Simple machines -- gears, changing speeds

Agenda:

 * Reading Rainbow: Coral Reefs**

**Videos**: Video of overview of coral reefs (3:01) @http://dsc.discovery.com/tv-shows/planet-earth/videos/shallow-seas-living-reefs.htm

//**Some great videos of coral reef animals from National Geographic:**// Deadly cone snail (the boys will love this -- armor, harpoon, deadly): []

Good kids video on sea anemone and clown fish -- symbiotic relationship []

Look at coral reef [|poster]for I spy parts of the reef.

Make several pages of animals that live in the reef (print front and back) . Front side has picture of animal and backside has several facts about the animal. Each child picks one of the animals to learn and share about. Look back at the I Spy Poster and find the animals that each child shared about.

Here is a link with various activities revolving around Coral Reefs


 * Activities: **

**1. make a color diffusing sea animal** (sea animal shapes can be purchased at Stones School Supply)

[]



**2. make a coral life cycle viewer** [|[]If you search for "coral life cycle viewer" I think you'll find one. I'm currently in a spotty-Internet location of the world and cannot get a good enough connection -- If you find a good link to an online version, let me know and I'll add it -- or feel free to add it yourself...

**snack when done with projects**

Simple Machines/Gears
Review simple machines -- ask for examples of each one Review gears and changing direction from last week -- how do gears work to change direction?

Introduce gears for changing speeds



Gears template for foam pieces: (note: to make it easier to cut out the gears, use a hole punch to make the initial teeth and then trim as needed)

Start with foam gears and mesh and brads, make and demo speed change using gears then use simple machines kits to also demonstrate speed change using gears

Building for demo at the Southeast Regional Library on 7/13/2012
**Review**:What we have learned in Ocean Odyssey so far and how we might show others by building on the base plate 3 groups build groups
