1) The document describes an educational robotics project where students build a model of a hungry alligator using WeDo kits. The alligator model is programmed to open and close its jaw when it "eats". 2) Alligators typically eat fish, insects, snails, and other small animals when young, and progressively larger prey like turtles and mammals as they grow older. They should not be petted due to their predatory nature. 3) The project teaches students about alligator biology, behavior, habitat, and reproduction, and how electrical energy is transferred to make the mechanical alligator jaw move.

3. Connect: Hungry Alligator Part 1 What was the alligator doing when Mia and Max saw it? The Alligator was opening and closing his big mouth. What happened as they stood near the alligator? The wind began to blow, and Max's cam flew away into the Alligator's big mouth.

4. Connect: Hungry Alligator Part 2 Do alligators really eat caps?Alligator will eat a cap if you tease him, but he would certainly prefer meat Why does an alligator have a large jaw?Large jaw helps alligator to grab passing by food (fish, animals or even hats)

5. Connect: Hungry Alligator Part 3 What kind of food does an alligator eat? When young, they eat fish, insects, snails, crustaceans, and worms. As they grow, they take progressively larger prey items, including larger fish such as gar, turtles, various mammals, birds, antelope and other reptiles. Would you pet an alligator? Why? Why not?You should not pet alligator, because alligator is not demarcated animal and it prefer hunting to petting.

14. Contemplate: Hungry Alligator Scientific classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Crocodilia Family: Alligatoridae Genus: Alligator Habitat Alligators are only native to the United States and China

15. Contemplate: Hungry Alligator Behavior Although alligators have a heavy body and a slow metabolism, they are capable of short bursts of speed, especially in very short lunges. Diet When young, they eat fish, insects, snails, crustaceans, and worms. As they grow, they take progressively larger prey items, including larger fish such as gar, turtles, various mammals, birds, antelope and other reptiles.

16. Contemplate: Hungry Alligator Human uses Alligators are raised commercially for their meat and skin, which is used for bags and shoes. Reproduction Alligators generally mature at a length of 6 feet (1.8 m). The mating season is in early spring.

17. Contemplate: Hungry Alligator Sex The sex of the offspring is determined by the temperature in the nest and is fixed within 7 to 21 days of the start of incubation. Incubation temperatures of 86 °F (30 °C) or lower produce a clutch of females; those of 93 °F (34 °C) or higher produce entirely males. Baby alligators Baby alligators have an egg tooth that helps them get out of their egg during hatching time. They also have a muscular flat tail that propels them forward while they swim
