Tuesday: Sea Star

Apr 22, 2015   //   by Miss Kim   //   Daily Lessons  //  Comments Off on Tuesday: Sea Star

Calendar:   Discussed the date in English and Spanish. Lucas put the number on the calendar, discussed the pattern and found the day of the week in Spanish.  We reviewed our Sign Language, Spanish, Sight words  and Numbers in English and Spanish.

Fun Facts/Brainstorming:  Reviewed what the kids learned about Plankton and Jellyfish yesterday.  Today the children told us what they know about Sea Stars.Discussed:  How do you think a sea star moves?  Starfish are echinoderms (spiny skinned sea urchins). They are also known as sea stars and are not really fish despite the name been given to them. Starfish cannot swim, and they do not use gills to breathe.  There are over 2,000 species of starfish.  A sea star’s spines are used for protection from predators, which include fish, sea otters and birds. Starfish come in a variety of colors and have many different types of patterns.  They are found in the deep blue sea of the ocean and shallow water as well. They are found in every ocean of the world. They are never found in fresh water. Amazingly, sea stars can regenerate lost arms. This is useful if the sea star is threatened by a predator. The starfish can drop an arm to get away. Sea stars house most of their vital organs in their arms, so some can even regenerate an entirely new sea star from just one arm and a portion of the star’s central disc. It takes almost a year for this to happen.  The Coscinasterias Calamaria also known as the eleven-armed sea star has an arm-spread that can go up to 30 cm. As the name suggests, it does have eleven arms but there are times when the number can go up to 14.

Creative Development: Discussed:  What do you think a sea star feels like?  Sea stars have hard, bumpy skin that protects it from predators.  Children played a game.  We set out dice and the rocks, then the children explored placing different amounts of rocks on the star shapes.  They then placed stickers on their stars and count how many stickers are on the stars.  Then they closed their eyes and felt the sea stars also to see if they could feel which star was their own.  

Physical Development: Discussed:  What do you think a sea star eats that people also eat?  A sea star’s diet can include barnacles, snails, sea urchins, clams and mussels.  We looked at the star shape and then compared  the shape of bread to the shape of the star.  Asked what is similar and different.  Then we toasted the sliced bread used a star cookie cutter to cut the bread into a star shape.  Then we spread peanut butter(or cream cheese) on the bread.  Then we covered it with crispy rice cereal and the children got to enjoy eating their starfish.

Physical Development: Discussed:  How do you think starfish eat?  Invited the children to search the room for things they can squeeze or squish in their hands(balls, beanbags, stuffed animals, etc.)  Starfish often wrap their arms around their prey and squeeze then to open the shells.  Gave the children grapes and had them squish it with their whole hand  or just with fingers.  Then they looked inside and described what they saw.  They then ate the squished grapes.

Language and Literacy:  Discussed:  What body part do you think a sea star has.  The children then moved their arms, legs and head and described how they move or identify each part.  I then read star facts and invited the children listen and draw a picture of what they heard.  A star has:  2-stomachs, 5-legs(some can have more), Many small feet on each arm, 1-mouth in the center, An eye at the end of each arm.  The children shared their drawings with each other.

Show and Tell: The children brought in a Star Item.  They came up one at a time to show their item and discuss how it looked like a star.

Afternoon Centers:  Center 1-  Bumpy Sea Star-The children created their own “Sea Star” by placing stickers on their star for their own unique design. They then counted how many stickers were on their star.
