Need for lesson - Sandpaper Globe (Montessori material)
can be pasted onto an index file card for quick reference
We have learned about all of the continents of the Earth. Can we name them on this Sandpaper Globe? What do we call all of the blue on this globe? Oceans. The largest ocean is the Pacific Ocean (point it out on the globe). The Pacific Ocean contains many different islands. What is an island again? The second largest ocean on Earth is the Atlantic Ocean. The third largest is here, called the Indian Ocean. Then we have the Arctic Ocean on this part of the Earth. During winter the Arctic Ocean is almost completely covered in sea ice.
The oceans are filled with many types of marine life. They include mammals, fish, mollusks, and crustaceans. There are also many plants that grow in the oceans. Some of them are algae, sea grass, and kelp.
Scientist divide the ocean up into horizontal zones. The sunlit zone, near the top is full of life with plants and animals. The twilight zone comes next as you go deeper into the ocean. It is colder and darker in this zone, having less life. Way down deep is the icy-cold dark zone. It is very very dark down in this zone becaus there is no sunlight that reaches it.
Shorelines are where oceans and seas meet land. There are many different types of shorelines. There are rocky shores, marshes, dunes, forests, and beaches. Sometimes when you are at the beach the water may come up high onto the beach or be far out and you have to walk out to get into the water. This is because of tides. The pull of gravity from the Sun and the Moon creates tides that in turn creates ocean currents.The gravitational pull of the moon creates two types of tides: high and low.
What about the waves in the ocean, if you have been to the beach, do you like to jump in the waves? Waves are actually energy. It is energy that moves across the oceans surface. In the case of ocean waves, wind provides the energy. Wind causes waves that travel in the ocean. The energy is released on the shorelines. If a strong wind is blowing across the ocean what size waves do you think there will be?
Tide Chart - I made this little chart to show the children when discussing the tides at the ocean.
Ocean Zones - This is another chart I made to show the children when we talk about the different ocean zones.
Ocean Animal Matching
The oceans of the world are big and blue
Remembering their name, that easy for you.
The Pacific, Atlantic, Indian too,
Don't forget the Arctic, or we trick you!
I Went to the Ocean
I went to the ocean and what did I see?
A beautiful seashell, was waiting for me.
I piut on my swimsuit, and played in the sand,
I built up a castle,and,boy, it was grand!
Just visit the ocean, I'm sure you'll agree,
There's nothing as nice, as a day a sea!
Need for lesson - A book about jellyfish, jellyfish art idea, and Parts of a Jellyfish (MontessoriPrintShop.com)
Talk with the children about jellyfish. Jellyfish are found in all oceans. Some jellyfish sting and other do not. They are not strong swimmers so they drift along ocean currents. Jellyfish like to eat tiny plants, shrimp, fish, and crabs. Some jellyfish are clear in color and others are vibrant colors like pink, yellow, blue, and purple. Ask if they think a jellyfish is a kind of fish? Why or why not? To find out more about jellyfish, lets read this book. (Read book of choice)
Parts of a Jellyfish (before it is made into a booklet)
Jellyfish - Children cut slits along the bottom of a white lunch bag (you can have lines pre-drawn on the bags for children to cut along). Children can paint the bags to make jellyfish puppets.
