We just posted our new Activity Guide, Robotic Zoo - check it out on our
Resources Page!
It integrates robotics challenges with biology concepts.... in other words, you make an
Iguana-bot and mimic the behavior of cold-blooded animals - who wouldn't find that fun?!
Actually, I learned that "cold-blooded" is a misleading term that has fallen out of favor with scientists today; just shows how science has changed since I was in elementary school. So, we incorporated info on the more accurate term "ectotherms".
Some more interesting biology facts I learned:
- Possums are the only marsupial in North America, and they faint when scared. They're not just "playing" dead; they are unconscious!
- Speaking of "playing dead" - some snakes actually ooze drops of blood to make the act more convincing!
- Venus Flytraps have tiny hairs that trigger the snapping response when an insect lands on it. And multiple hairs in a row need to be touched before it triggers the snap - to prevent false alarms from non-moving (non-protein) objects other than insects. Pretty complex system for a plant!
- Dolphins' left & right rows of teeth are offset a little. Some scientists theorize that this helps dolphins interpret sonar data and detect whether objects are more to the left or right of them.
