## Slide 1: Junior Explorer: Animal Kingdom
* An introduction to the safari-themed guide on how scientists classify animals.

## Slide 2: The Big Secret: The Backbone
* **Vertebrates:** Animals with a backbone (e.g., humans).
* **Invertebrates:** Animals with no backbone; they make up the majority of species.

## Slide 3: Meet the Vertebrates Family
* **Fish:** Gills, lay eggs, live in water.
* **Amphibians:** Gills then lungs, smooth skin.
* **Reptiles:** Dry scales, lay eggs on land.
* **Birds:** Feathers, wings, warm-blooded.
* **Mammals:** Hair/fur, live birth, warm-blooded.

## Slide 4: Detective Work: Check the Temperature!
* **Cold-Blooded:** Body temp depends on surroundings (Fish, Amphibians, Reptiles).
* **Warm-Blooded:** Animals control their own body heat (Birds, Mammals).

## Slide 5: Jungle Guide Quiz!
* Q: Fur, lungs, and warm-blooded. 
* A: Mammal.

## Slide 6: Welcome to the Majority!
* Most animals on Earth are Invertebrates without backbones.

## Slide 7: The Arthropods: Armored Animals
* Largest invertebrate group.
* Key features: **Exoskeleton** (hard covering) and segmented bodies.
* Examples: Dragonflies, spiders, crabs.

## Slide 8: Other Invertebrate Friends
* **Mollusks:** Hard shells (Snails, Clams).
* **Worms:** Soft bodies (Earthworms).
* **Sea Stars & Jellyfish:** Various outer coverings from tough to none.

## Slide 9: Pop Quiz!
* Q: Which group has an exoskeleton and jointed legs?
* A: Arthropods.

## Slide 10: Explorer Badge Earned!
* Summary of Vertebrates (backbone) vs. Invertebrates (no backbone) and the distinction between warm-blooded and cold-blooded body temperatures.
