Unit 1: Saltwater<\/u><\/b><\/font>

<\/p>\n

\n
   1. Salty Water<\/a><\/b><\/font><\/dt>\n
Students make salt water, taste it at different depths with a straw; then evaporate drops of salt and fresh water.\n<\/a>\n

<\/p>\n<\/dd>\n

   2. Saltwater Floaters<\/a><\/b><\/font><\/dt>\n
Students sink an egg in a cup of freshwater; then add salt until the egg floats. They check the buoyancy of familiar objects – carrot, nut, pebble. <\/a>\n

<\/p>\n<\/dd>\n

   3. Water as a Weight Lifter<\/a><\/b><\/font><\/dt>\n
Students test to see how heavy a bag of pebbles is when it is submerged, versus when not submerged. <\/a>\n

<\/p>\n<\/dd>\n

Unit 2: Hermit Crabs<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Intertidal Tales<\/a><\/b><\/font><\/dt>\n
Students role play a beach visit practicing beach etiquette (turned stones should be turned back, animals should be left in their homes…) and more. <\/a>\n

<\/p>\n<\/dd>\n

   2. Observing Hermit Crabs<\/a><\/b><\/font><\/dt>\n
Students observe live crabs move, hide, and scurry after food; then students enact crab behavior. <\/a>\n

<\/p>\n<\/dd>\n

   3. Borrowed Shells<\/a><\/b><\/font><\/dt>\n
Students use literature, song and writing to examine how hermit crab adaptations help these animals meet the challenges of their habitat. <\/a>\n

<\/p>\n<\/dd>\n

   4. Clothespin Claws<\/a><\/b><\/font><\/dt>\n
Students model foraging behavior before and after losing a clothespin claw, making bar graphs to gauge foraging efficiency. <\/a>\n

<\/p>\n<\/dd>\n

Unit 3: Sea Anemones<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Sea Anemones<\/a><\/b><\/font><\/dt>\n
Students learn anemone anatomy, then enact anemone behaviors at high and low tide. <\/a>\n

<\/p>\n<\/dd>\n

   2. Making Sea Anemones<\/a><\/b><\/font><\/dt>\n
Students design and build a paper anemone model that has retractable tentacles. <\/a>\n

<\/p>\n<\/dd>\n

Unit 4: Barnacles<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Barnacles<\/a><\/b><\/font><\/dt>\n
Students observe live barnacles (or a film) dry (low tide), then submerged (high tide), and draw inferences from observations. <\/a>\n

<\/p>\n<\/dd>\n

   2. Have or Do?<\/a><\/b><\/font><\/dt>\n
Students are asked to distinguish between barnacle structures (“Have”) and barnacle behaviors (“Do”). <\/a>\n

<\/p>\n<\/dd>\n

   3. High and Dry<\/a><\/b><\/font><\/dt>\n
Students observe the desiccation of vegetables left in a dry pan (low tide), and compare with vegetables submerged in another pan (high tide). <\/a>\n

<\/p>\n<\/dd>\n

   4. Drying on the Line<\/a><\/b><\/font><\/dt>\n
Students compare the drying rate of a folded paper towel to that of an unfolded paper towel, to explore the effects of animal shape on desiccation rate. <\/a>\n

<\/p>\n<\/dd>\n

Unit 5: Limpets and Chitons<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Limpets and Chitons<\/a><\/b><\/font><\/dt>\n
Students observe differences between chitons and limpets, and infer the adaptive values of the differences. <\/a>\n

<\/p>\n<\/dd>\n

   2. Hold On<\/a><\/b><\/font><\/dt>\n
Given an array of household items, students predict which items will be least affected by the force of waves; then test by spraying with a garden hose. <\/a>\n

<\/p>\n<\/dd>\n

   3. Life on the Rocks<\/a><\/b><\/font><\/dt>\n
Students design a “holdfast” for a “limpet” (piece of sponge) and attach it to a fence. Designs are tested by throwing buckets of water on the “limpets”. <\/a>\n

<\/p>\n<\/dd>\n

   4. Creating Chitons<\/a><\/b><\/font><\/dt>\n
Each student forms eight clay shell plates, and then overlaps them to form a model of a chiton. <\/a>\n

<\/p>\n<\/dd>\n

Unit 6: Sea Stars<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Sea Stars<\/a><\/b><\/font><\/dt>\n
Students study diagrams of sea stars that show their parts, their variety, and how they eat clams. <\/a>\n

<\/p>\n<\/dd>\n

   2. Sea Star Math<\/a><\/b><\/font><\/dt>\n
Counting by fives, students add the number of total rays in a group of sea stars. <\/a>\n

<\/p>\n<\/dd>\n

   3. Creating Graphs<\/a><\/b><\/font><\/dt>\n
The great variety of sea animals provides a wonderful device for introducing representational graphs. <\/a>\n

<\/p>\n<\/dd>\n

Unit 7: Octopus<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Octopus<\/a><\/b><\/font><\/dt>\n
Students form a “tentacle”, passing a “crab” from tentacle tip to octopus mouth, and also model octopus jet propulsion. <\/a>\n

<\/p>\n<\/dd>\n

   2. Octopus Changes<\/a><\/b><\/font><\/dt>\n
Students draw an octopus using disappearing ink to model camouflage behavior. <\/a>\n

<\/p>\n<\/dd>\n

Unit 8: Seaweeds<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Seaweeds Are Plants of the Sea<\/a><\/b><\/font><\/dt>\n
Students compare the form and function of seaweed to land plants. For locales with seaweeds, plans are included for “sun prints” and pressed seaweeds. <\/a>\n

<\/p>\n<\/dd>\n

   2. Seaweed Anyone?<\/a><\/b><\/font><\/dt>\n
Students look for algin and other seaweed derivatives on food ingredient labels to learn that they are present in many common foods, such as ice cream. <\/a>\n

<\/p>\n<\/dd>\n

   3. Interdependence<\/a><\/b><\/font><\/dt>\n
Students make paper models of land and sea based food chains; then assume the roles of sun, plants and animals and link together in a food web with yarn. <\/a>\n

<\/p>\n<\/dd>\n

Unit 9: Tidepool Model<\/u><\/b><\/font>\n

<\/p>\n<\/dt>\n

   1. Papier-m\u00e2ch\u00e9 Tidepools<\/a><\/b><\/font><\/dt>\n
Students use their new knowledge of the sea and its life to construct a life-sized papier-m\u00e2ch\u00e9 tidepool, populated with clay animals and plants. <\/a>\n

<\/p>\n<\/dd>\n
