To solve this sorting task, we need to separate the animals into two groups based on whether they have a backbone (vertebrates) or not (invertebrates).
Step 1: Understand the Definitions
*
Vertebrates: Animals that have a backbone or spine inside their bodies. This group includes mammals, birds, reptiles, amphibians, and fish.
*
Invertebrates: Animals that do *not* have a backbone. This group includes insects, worms, jellyfish, octopuses, starfish, and snails.
Step 2: Sort Each Animal
Let's look at each animal card shown in the activity and decide which group it belongs to:
1.
Sea Turtle: It is a reptile with a shell and bones inside. ->
Vertebrate
2.
Starfish: It has no bones; its body is supported by a water vascular system. ->
Invertebrate
3.
Bee: It is an insect with an exoskeleton (hard shell on the outside), but no internal backbone. ->
Invertebrate
4.
Sea Anemone: It is a soft-bodied marine animal related to jellyfish and corals. No bones. ->
Invertebrate
5.
Fish (Clownfish): All fish have backbones. ->
Vertebrate
6.
Snake: It is a reptile. Even though it has no legs, it has a long backbone made of many vertebrae. ->
Vertebrate
7.
Octopus: It is a mollusk (soft-bodied). It has no bones at all. ->
Invertebrate
8.
Frog: It is an amphibian. It has a skeleton with a backbone. ->
Vertebrate
9.
Jellyfish: As the name suggests, it is mostly jelly-like tissue. No bones. ->
Invertebrate
10.
Worm: Earthworms and similar worms are soft-bodied with no skeleton. ->
Invertebrate
11.
Seagull: It is a bird. All birds have backbones. ->
Vertebrate
*(Note: There is a partial image of a chameleon/lizard on the left edge and a crab/spider leg on the right edge. Based on standard biology:*
* *Lizards/Chameleons are reptiles -> Vertebrate)*
* *Crabs/Spiders are arthropods -> Invertebrate)*
Step 3: Final Grouping
Vertebrates (Have a backbone):
* Sea Turtle
* Fish
* Snake
* Frog
* Seagull
* *(Lizard/Chameleon if included)*
Invertebrates (No backbone):
* Starfish
* Bee
* Sea Anemone
* Octopus
* Jellyfish
* Worm
* *(Crab/Spider if included)*
Final Answer:
Vertebrates: Sea turtle, Fish, Snake, Frog, Seagull
Invertebrates: Starfish, Bee, Sea anemone, Octopus, Jellyfish, Worm
