Friday: Sea Sponge

Apr 25, 2015   //   by Miss Kim   //   Daily Lessons  //  Comments Off on Friday: Sea Sponge

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 Words, Sight words and Numbers in English and Spanish.

Fun Facts/Brainstorming:  Reviewed what the kids learned about Earth day.  Today the children told me what they know about the Sea Sponge.  Discussed:  Do you think a sea sponge is living  or nonliving?  Why?  Fun facts:  There are around 6000- 10000 known species of sea sponges around the world.  You must be really amazed to know that sea sponges can hold around 16,000 animals inside them!  They allow huge quantities of water to pass through them, an estimated 20,000 times greater than their own volume.  In just one day a few sponges can clean up a whole big sea.  Sponges can grow in sizes between a few inches to 10 feet wide.  Mostly, sponges are marine animals and can live up to the depth of 9000 feet in Deep Ocean where sunlight can never reach. Sea sponges do not have complex immune systems like other animals, but they do release harmful toxins in the water to prevent intruders and predators.  These toxins can produce skin rashes on touching and holding them. Some deep sea sponges can live up to the age of 200 years.  Some calcified demo sponges have been reported to live for thousand years and more.

Creative Development: Discussed:  What color sponges would you like to see in the ocean?  Sea sponges come in a rainbow of beautiful colors  The more light that shines on them, the brighter they appear.  Had the children to explore the feel of the sponge then try to find something in the room that feels that same or similar.  Looked at the afternoon centers.

Science:  Discussed:  What do you think is inside of a sea sponge?  Sea sponges can hold up to 16,000 animals inside of them.  Passed around the sponges and invited the children to hold squeeze and feel them.  Had the children to predict what they can pick up with a dry sponge.  What abut a wet sponge?  We set out a tray of dirt, sand or other particles and the children tried to pick up the materials with a dry sponge.  Wet the sponge and try again.  Then we squeezed the sponge over a coffee filter to see what was “cleaned up”.  

Mathematics and Reasoning: Discussed:  How big do you think a sea sponge can be?  Giant barrel sponges can grow large enough to fit a person inside (over 5 feet tall and over 6 feet wide).  The largest one found was over 8 feet wide! Had the children explore the room to see what they thought they would fit inside.  Set out containers and had the children to pretend they are different sizes of barrel sponges.  Had the children to guess which items they think can fit inside each container then test their predictions.  Asked them if they could fit inside.  The children came up and all tried to fit in the toy bins.  Miss Kim and Miss Lindsay couldn’t fit in the toy bins.  

Social and Emotional Development: Discussed:  What would you like about exploring the ocean?  Had the children look at photos on cards and decide on a favorite.  What do they discuss or do while exploring the photos?  Set out the Would You Rather set and choose a question to ask.  Placed the matching photos on the poster and invite each child to place a shell above the photo of his choice.  Would You Rather Questions:  Would you rather ride on an octopus or in a submarine?  Would your rather swim with a diver or a shark?  Would you rather touch a sea sponge or a shark?  Would you rather eat a sea sponge, a shark or an octopus?  Would you rather explore a sea cave, sea sponges, or a school of sharks?  Would you rather be a diver or an octopus?

Afternoon Centers:   Center 1-  Sponge Stencils:   They used the stencils to sponge paint sea sponges in the ocean scene.  Invited each child to show and tell a story abut the ocean life in the scene.
