Calendar:   Discussed the date in English and Spanish. Harper put the number on the calendar, discussed the weather and pattern.  She found the day of the week in Spanish.

Fun Facts/Brainstorming:  Reviewed what the kids learned about sharks.  Today the children told me everything they know about Seat Turtles.  Discussed:  What do you see when you look at a sea turtle?  Fun facts:  Sea turtles are a group of reptiles that can be found in all oceans of the world except int the polar area. Out of 7 known species of sea turtles, 6 are critically endangered.  Main factors that decrease number of sea turtles are : poaching, loss of nesting or feeding areas, accidental catch (called bycatch), ocean pollution and weather changes (global warming).  Sea turtles are very old organisms.  They have lived on the Earth more than 220 million years.  They managed to survive weather changes which killed the dinosaurs.  They spend most of their life in the ocean.  Females can be seen on the beaches only during nesting season.  They lay eggs in holes in the sand.  These “nests” can’t be recognized easily because turtles cover them with additional layers of sand.  Depending on the species, each nest contains between 60-200 eggs.  Sea turtles don’t have teeth, but their mouths are adapted to each type of food that they normally eat.  Green Sea Turtles are vegetarians who eat sea grass, while other turtles eat crabs, clams, jellyfish, sea cucumber.

Mathematics and Reasoning: Discussed:  How do you think baby sea turtles are born?  Explored aiming and tossing the pompom to a specific target(blocks, a book, tape mark) .  Children tossed a pompom onto the game board to find out which sea turtle hatched.  They then flipped over the egg card that matches to reveal the turtle.  Repeated until all baby turtles have been hatched.  

Physical Development: Discussed:  What do we think can harm sea turtles?  The children looked at posters and choose the animals that might want to eat a sea turtle.  Explained that baby sea turtle eggs are laid on the beach.  When the eggs hatch, the babies must run for the water before land predators, such as dogs, skunks, raccoons or rats, can get them.  The children pretended to nest and imagine being newborn baby sea turtles hatching.  Choose one child to be a predator and chase the babies.  The sea turtles have to run to the ocean(other side of room) before the predator catches them.  Each child got a turn to be the predator and tag the baby sea turtles while they crawled fast for the ocean.  We counted how many kids made it to the ocean and how many got eaten.  

Social Studies: Discussed:  What do you think it would be like to live on an island?   Asked the children what lives on their island and what lives in the water.  Had the children look at the World  Map to locate Galapagos Islands.  Explained that they are home to many beautiful sea creatures such as the green sea turtle.  

Science:  Discussed:  How are sea turtles different from other turtles?  Set out photos and invited the children to explore the differences and similarities between turtles and tortoises.  Sea Turtle Fun facts:  Does a sea turtle have a shell?  Yes  What does a sea turtle eat?  Plants, insects and fish.  Where does a sea turtle live?  Sea turtles spend most of their time underwater.  Can a sea turtle swim?  Yes. Their front feet have webbed toes or fins.  Fun facts for a Tortoise:  Does a tortoise have a shell?  Yes.  What does a tortoise eat?  Shrubs, cacti, grasses and flowers.  Where does a tortoise live?  The tortoise lives almost entirely above water.  Can a tortoise swim?  NO. Their feet are hard and scaly with claws for climbing and digging.
