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.

Construct: Hungry Alligator
Discuss the entire process in detail. Step 1 •- The electrical energy transfers from the computer and powers the motor;
Step 2 •- The motor makes the crown gear to turn at 90 o angle to the next gear;
Step 3 •The gear turns a small pulley and a belt; (they are on the same axle as a gear)
Step 4 •The belt turns a large pulley;
Step 5 •The movement of the large pulley opens and closes the alligator's jaw.
Construct: Hungry Alligator
Use the blocks shown to create the program with the blocks to get the alligator to close its jaw when it eats.

Habitat
Alligators are only native
to the United States and
China
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.
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.
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
