Can dolphins see themselves in a miror?

Babies show signs of recognizing themselves in the mirror at about 15 to 18 months of age. But dolphins can recognize themselves even earlier—as young as 7 months old, according to a study recently published in PLOS One.

Self-recognition takes sophisticated cognitive processing and was once thought to be a uniquely human ability. But since the 1970s, great apes, elephants, dolphins, and magpies (yes, a crow) have shown the capacity to recognize themselves in a mirror.

When the ball is rising up, it gains kinetic energy. when the ball reaches the very top, it will have all potential energy, until it falls back down and gains it kinetic energy. finally when you catch the ball or it falls back down, it would have gained its potential energy back.

Writing, you can revisit previous parts of the lesson by returning to the course map. be sure to refer to the lab’s student guide, which you can find on the first page of the lab experiment activity
