I have rounded up some fun oyster shell crafts for kids. Also, look at my page Oceans Unit Study and Lapbook for more hands-on ideas.

Too, look at my page Seashore Beach Watching Unit Study and Seashore Lapbook for more fun ideas.

The oyster is a bottom dwelling creature. It filters sand in and out of its shell looking for food.

In the process of filtering sand, it produces a deposit of minerals that eventually turns into a pearl.

Simple Oyster Shell Crafts For Kids And Mollusks Activities

Too, oysters are a fun topic to study about in the summer along with doing the crafts I have listed below.

For example, here are some ideas for an oyster unit study or themed day.

Your child can describe the anatomy and ecological role of oysters and analyze oyster habitats and map where they live. Learn about filter feeding and understand how oyster reef habitats help the environment.

Next, look at some of these books about the group mollusks.

BOOKS ABOUT MOLLUSKS FOR KIDS

We prefer to read living books when we can find them.

Then add reference books as we can.

Add some of these books to your home library or to your unit study for the day.

About Mollusks: A Guide for Children

The book uses simple, easy-to-understand language to teach children what mollusks are, how they look, how they move, what they eat, and where they live. The beautifully detailed, realistic paintings of noted wildlife illustrator John Sill introduce readers to a variety of mollusks—from the small garden snail to the giant Pacific octopus. An afterword provides more details about the animals in the book.

Giant Squid (Robert F. Sibert Informational Book Honor (Awards))

The giant squid is one of the most elusive creatures in the world. As large as whales, they hide beyond reach deep within the sea, forcing scientists to piece together their story from those clues they leave behind.An injured whale's ring-shaped scars indicate an encounter with a giant squid. A piece of beak broken off in the whale's belly; a flash of ink dispersed as a blinding defense to allow the squid to escape-- these fragments of proof were all we had . . . until a giant squid was finally filmed in its natural habitat only two years ago.In this beautiful and clever nonfiction picture book about the giant squid, Candace Fleming and Eric Rohmann explore, both visually and poetically, this hidden creature's mysterious life.

The snail's spell

"Brilliant illustrations and a short text invite an unnamed sleeping, pajama-clad child into a garden teeming with wildlife. The boy gradually shrinks until he is so small he experiences things as a snail would. The incredibly detailed drawings and the idea of shrinking to enter another world should capture children's imaginations

Escargot

Escargot is an adorable French snail who only wants two things: 1) To be your favorite animal, and 2) To eat the delicious salad at the end of this book. Except this delicious salad has a carrot in it. And Escargot hates carrots. But when he finally tries one―with a little help from you!―he realizes that it’s not so bad after all.

The Snail House

Here is the story Grandma tells one evening on her wide veranda steps. It has Michael and Hannah and the disappearing baby in it, a tigerish bird, raindrops like sacks of water, and the hugest apple you ever saw. Oh yes . . . and the Snail House. So gather round, climb up now into Grandma’s lap. Darkness is falling, the air is still, and the story is just about to begin.

Cool facts about mollusks, ideas for amazing activities, and a tutorial for a decoupaged oyster shell are just a portion of what I have for you. Also, look at my page Oceans Unit Study and Lapbook for more hands-on ideas.

Mollusks are a fascinating group of animals that live mostly in water and have soft bodies, often protected by hard shells.

They are invertebrates, which means they don’t have backbones.

The Biggest House in the World

Today we are going to look at the 3 main types of mollusks-bivalves, gastropods, and cephalopods before we begin our craft.

3 MAIN TYPES OF MOLLUSKS

BIVALVES

(“Bi-” means two)These mollusks have two shells hinged together, like a book. They are usually filter feeders and don’t have a head or much visible movement.

Scallops – Can “swim” by clapping their shells together
Oysters – Create reefs and sometimes pearls
Clams – Live buried in sand or mud and use a foot to dig
Mussels – Attach to rocks using strong fibers called byssal threads

GASTROPODS

(“Gastro” means stomach and “pod” means foot—because they move on their stomach-foot!). This is the largest group of mollusks. Most have a single, spiraled shell, though some (like slugs) have none at all.

Snails – Found on land and in water, with a coiled shell for protection
Slugs – No shell, but covered in mucus to keep from drying out
Sea Hares – Large marine snails with soft bodies and beautiful colors
Whelks and Conchs – Marine snails with beautiful spiral shells.

CEPHALOPODS

(“Cephalo” means head and “pod” means foot—because their feet (tentacles) come out of their head!) Cephalopods are the smartest and fastest of the mollusks. Most don’t have external shells, except the nautilus, and can change color and texture.

Octopuses – Eight arms, high intelligence, and the ability to squeeze into tiny spaces
Squid – Ten limbs (eight arms, two longer tentacles) and fast swimmers
Cuttlefish – Similar to squid but with a special shell inside (the cuttlebone)
Nautiluses – Have beautiful, coiled shells and many tentacles, but lack the speed of other cephalopods

8 COOL FACTS ABOUT MOLLUSKS

Cephalopods like squid, octopuses, and cuttlefish use special skin cells called chromatophores to change their color and pattern for camouflage, communication, and to scare off predators.
In ancient times, people harvested murex snails to make a deep purple dye known as Tyrian purple, used in royal clothing. It took thousands of snails to make just a small amount, which is why it became a symbol of wealth and power
Oysters can filter up to 50 gallons of water per day, they do this to extract food and minerals from the water.
Octopuses can open jars, use tools, and even solve puzzles!
Scallops have dozens of tiny blue eyes along the edge of their shell.
Some oysters produce pearls- a smooth, shiny ball formed when a grain of sand gets trapped inside their shell.
Giant clams can grow over 4 feet wide and weigh more than 500 pounds.
Some sea snails have shells that spiral in different directions—right (dextral) or left (sinistral).

Finally, look at how to do this fun decoupaged oyster shell.

HOW TO CREATE A DECOUPAGED OYSTER SHELL

You will need:

Decorative napkins or tissue paper
Mod Podge (or white glue mixed with water)
Small paintbrush
Scissors
Optional: gold paint or a gold paint pen

If you are using shells you found on the beach (or collected from a seafood restaurant) clean the shells to make sure your oyster shells are free of dirt and debris.

You can scrub them lightly with soap and water.

Using a paintbrush, coat the inside of the shell with Mod Podge.

Separate the thin printed layer from the white layers.

Gently press the paper onto the Mod Podge-coated shell. Smooth it out carefully to avoid wrinkles.

While still wet carefully tear away the excess away from the edges all the way around the shell.

Once everything is dry, paint the edges of the shell with gold paint for a polished, elegant look or use any color you like to finish off the edge.

Here are a few of the creative ways you can put your decoupaged oyster shell to use. To hold your sea glass collection…

If you are looking for exciting Swiss Family Robinson activities, you have landed in the right place. Also, you’ll love more ideas on my post Swiss Family Robinson Unit Study.

There are so many great little rabbit trails you can take while doing a read-aloud of the Swiss Family Robinson.

For example, you can learn about the flora and fauna of the island, the journey to the island, how they survived and thrived, and what they ate.

Oysters were a plentiful delicacy that they found on the island and provided the family protein to help keep them strong and give them energy.

Exciting Swiss Family Robinson Activities | From Oyster To Pearl

They are still enjoyed today, steamed, grilled, fried, and in many recipes.

Naturally, I thought that it would be a great subtopic to chase down.

This might make a fantastic field trip to a restaurant to give them a try or perhaps make a recipe at home.

We are going to cover the journey from how an oyster turns pearl and how these beauties are formed inside the unassuming rough-looking shell.

I have directions for making your cute oyster craft as well as a few resources and other oyster and pearl ideas that give you plenty of fun to work on.

Foraging Wild Edible Plants of North America: More than 150 Delicious Recipes Using Nature's Edibles

Edible wild plants are nature’s natural food source, growing along roadsides, sprouting in backyards, and blooming in country fields. North America’s diverse geography overflows with edible plant species.

Oyster Formation Facts

First, oysters are often found in groups, called “reefs” or “beds”. They create these by growing on top of as well as next to each other, creating their own ecosystem.
Oyster reefs can occur naturally or be created by oyster farmers.
Within just 12 hours of birth, they begin to build their shells. This process is done by pulling calcium out of the water and depositing it as calcium carbonate on the outside of their bodies.
Once they reach approximately 3 weeks old they are heavy and attach themselves to the reef or bed made by the other oysters.
The inside of an oyster shell is usually white or pearl colored. But the outer shell takes on a variety of different colors. A lot are dark gray, but the Pacific oyster can have purple, brown, and white coloring while Cornish Native Oysters are blue.
Not only do they create an ecosystem for themselves but also many other fish and creatures. Because they do not move they eat what passes by and act as a filtration system, creating cleaner water.
Inside the oyster is the edible part, or the adductor muscle which is a creamy beige color.

Next, look at these facts about pearls.

Pearl Formation Facts

Pearls are the result of a grain of sand or other irritant getting under the “skin” or mantle.
When the irritant is present the oyster secretes a mucus with a mineral calcium carbonate in it that is called the nacre and it envelopes the irritant.
Over time this material hardens and becomes a pearl. This process can take six months. to four years to develop. Larger pearls take longer and are more valuable.
Perfectly round pearls are not naturally occurring, pearls in the wild are usually small and irregularly shaped.
Pearls can come in a wide variety of colors, most commonly white, cream, pink, and purple but they can also be champagne, chocolate, blue, gold, silver, and lavender.

Moreover, look at these other activities.

Swiss Family Robinson Activities – From Oyster To Pearl

Before we jump into our oyster with a pearl craft today here are a few more hands-on activities I think that you will enjoy.

These Oyster Cookies are adorable and look so yummy. I know they would make a fun hands-on project to go along with your study.
Learn How to Draw an Oyster With a Pearl for a little art study that fits perfectly.
Grab a batch of these oysters with a pearl inside and let everyone in the family pop one or two open to see what they get, what a fun keepsake!
I thought that this Decoupage Oyster Shell Trinket Dish would be perfect for middle and high school teens if you have or want to grab some clean oyster shells.
Not only can something like artificial pearls be used for pretty and usable crafts but they can also be used as manipulatives for math, in sensory bins, or dramatic play making them very versatile and worth the small investment.

Finally, Ocean Anatomy proved once again to be a fantastic resource for a nature lesson. While they did not go over oyster shells there is a wonderful section on pearls.

Paper Plate Oyster

You will need:

Paper plate
Foam craft ball
Pink craft foam
gray/tan craft paint
Pearlescent craft paint
Sponge
Hot glue

First, turn your paper plate upside down so that the “bowl” is facing down and sponge paint some color and texture on it.

You can skip this part if you like but it provides a great opportunity to talk about how the shell is formed and the variety of colors they might be.

Paint a craft foam ball a pretty pearly color and set it aside to dry.

Allow the paint to dry completely then fold the plate in half, trim the outside a bit if you like to create a more elongated shape like a real oyster.

Use paint or a marker and add a little bit of color around the edges on the inside of your oyster to create the fringe.

Cut a piece of cream craft foam or felt (or construction paper) slightly smaller than the inside of your plate and glue it into place as the adductor muscle.

Hot glue the “pearl” to the center.

For older students, you can also have them label the parts of an oyster as well using the model that they just made.
