ITEC 800: PROJECT 4 Superpowers of Bats!
Transcript of ITEC 800: PROJECT 4 Superpowers of Bats!
How do Bats Keep From Flying into Your Hair?
Bats are the only mammals that can fly.
Bats, like the best submarines, are equipped with Sonar.
Watch this video to see bats in action!
Bats emit sounds from their mouth or nose and listen for returning soundwaves to orient themselves, locate prey, and find water to drink (Van Ryckegham, 1998). Bat sounds are usually inaudible to humans. The frequency and decibel ranges can vary greatly. A bat that emits softer sounds needs larger, more sensitive ears to capture feedback (Harris, 2013).
Bats and Dolphins: Masters of Sonar
Vampire bats drink blood, the fox bat is giant fruit bat,
cave bats are insect eating bats.
All of them are known to eat an incredibly amazing amount.

Most fly at night--how can they catch their prey (largely insects) and avoid flying into things?
This question seeks to produce cognitive dissonance in the learner. For a learner who does not yet know about echolocation, a sense of mystery and curiosity is aroused.
A Cognitivist Lesson
by DeLonzo Pope and Eric Peterson
Youtube Video by BBC Earth: "Bats hunting their prey - Top Bat - BBC"
The use of BBC documentary material provides analytic access to current expert constructs of science.

Remember our submarines? Sonar works underwater as well as in the air.
Even though dolphins and bats are not closely related genetically, both types of mammals developed echolocation as a hunting strategy. This is called convergent evolution, when quite distinct species independently evolve quite similar strategic mutations (Pennisi, 2013).
This new wrinkle in the lesson material aims to decontextualize the exploration from bats specifically to all mammals in general and to provide scientific approaches to transfer to other analytic contexts. The submarine cue also seeks to provide diagnostic access to the learning process, to enable learners to monitor their own progress.
Bonus Bat Power:
Hang Upside down
Bats are also known for another
super power: Hanging upside down! Ok, well maybe it is not a superpower, they are just better at it than most other mammals; including sloths, apes, some bears, opposoms and oh lets not forget...people!
Bats in flight
Remember, bats are the only mammmal that actually fly.
How do Bats achieve true flight?
List the ways that the bat's wings different from the other winged animals that fly or glide?
What is that in the sky?
Vampire bats are creatures that DO drink blood. They have a strong repulsive effect on humans.
Is this the bat that comes to mind when of halloween? Although these vampires don't normally feed on people, they do drink the blood of animals, and they can feed on their sleeping prey almost undetected. And people have feared them for centuries!
How do they bite without the animal knowing it ?
It's another bat superpower! Explore below!
Bats keep naturally keep some insect populations in check, but how is the bat population in kept in check?
Vampire Bat superpower:
Super Heat vision
via smelling sensors
Here is a rare look at the vampire bat in action!
Caution! This video might just really creep you out!
This is a Pemba flying fox. It not a fox! It is a bat with a wingspan that can reach 5 and 1/2 feet.
The question above engages the learner to experience learning by a cognitive concept called an organization effect. In this case catagorizing wing attributes an combining schema.
Vampire bats have the ability to detect the their prey in the dark by smell! Not just any smell, a heat sensing smell! ( )
The learner is asked to go into long term memory and therefore can link it with the new information being presented.
How much would you have to eat to consume food like a bat?
Have fun investigating and learning new things about the one mammal that can truly fly!
The bat's has had a large influence on man's imagination, fears and flight envy . Here are just a few.
