🎬 Watch First: What is a Mollusk?⏱ ~3 min

Watch this short video about mollusks. Pay attention to the body parts and vocabulary words you hear. You can scroll past this after watching.

While watching, listen for: mantle, radula, shell. These are the words you'll learn today! Mollusks include snails, clams, squids, and octopuses.

📸 Section 1: Draw or Photo a Mollusk ⏱ ~5 min

Draw a labeled diagram of a mollusk (snail, clam, or squid) showing its body parts, or take a photo of a real mollusk shell if you have one. Upload your drawing or photo here.

Drawing Tips: Try drawing a snail! Show the shell on top, the soft body underneath (the mantle), and the mouth area where the radula (tongue-like scraper) is located. Label each part!

Characteristics / Facts

Non-Examples

English Tip: The "mantle" is a thin layer of tissue that covers the mollusk's body — like a blanket. In snails and clams, the mantle makes the shell! In squids and octopuses, it's the muscular body covering.

✍️ Practice: Write 2 sentences using "mantle"

Example: "The snail's mantle produces the hard shell that protects its body."

📖 Section 3: Vocabulary - RADULA ⏱ ~8 min

Now learn about the radula — the special tongue-like scraper that most mollusks use to eat!

RADULA

/ˈræd.jə.lə/ (noun)

Definition (In Your Own Words)

Characteristics / Facts

Examples

Non-Examples

English Tip: The radula is like a tiny tongue covered in thousands of microscopic teeth. Snails use their radula to scrape algae off rocks — imagine a cheese grater! Clams and mussels do not have a radula because they filter food from water instead.

✍️ Practice: Write 2 sentences using "radula"

Example: "The snail uses its radula to scrape tiny bits of food off rocks and plants."

📖 Section 4: Vocabulary - SHELL ⏱ ~8 min

Learn about mollusk shells — the hard protective coverings that many mollusks have!

SHELL

/ʃɛl/ (noun)

Definition (In Your Own Words)

Characteristics / Facts

Examples

Non-Examples

English Tip: Mollusk shells are made of calcium carbonate — the same mineral in chalk and limestone! Snails have one coiled shell. Clams have two shells (called "valves") that open and close. Octopuses and slugs have no shell at all!

✍️ Practice: Write 2 sentences using "shell"

Example: "A clam has two shells that close tightly to protect it from predators."
