How Birds Make Movies

January 12, 2017

We all love to take pictures and videos of ourselves. Well, it looks like birds want to try it, too. In this wacky video, an eagle snatches a hiker’s videocamera and starts flying around with it, then finally puts it down and poses for a selfie (as we see here). Since the camera is sailing through the air, we get an amazing view of the mountains and scenery, as well as some feathers from the bird’s wings. The eagle also pecks at the camera, wondering if it’s something yummy to eat. Hopefully he found a better snack after that.

Wee ones: Other than the ceiling, what’s the highest thing in your room where an eagle could land?

Little kids: If the eagle took the camera for 1 minute and the hiker had used it for 1 hour, who used it for longer?  Bonus: The eagle carries the camera for 1 minute and 1 second. Since a minute has 60 seconds, how many seconds is that in total?

Big kids: If the eagle filmed you for 11 seconds, then you filmed the eagle for twice as long, how much video would the two of you have in total?  Bonus: We see the eagle’s wings about twice per second when the bird and camera start flying. How many wing flaps is that in 1 minute? (Reminder if needed: A minute has 60 seconds.)

The sky’s the limit: If the hiker and the eagle start 250 feet apart, and as they move towards each other the eagle is flying 4 times as fast as the hiker is running, how far from their starting points do they meet?

 

 

 

Answers:
Wee ones: Answers might include a bedpost, the top of a lamp, or the top of a window.

Little kids: The hiker used it longer.  Bonus: 61 seconds.

Big kids: 33 seconds.  Bonus: 120 wing flaps.

The sky’s the limit: 50 feet from the hiker’s starting point, and 200 feet from the eagle’s starting point.  If the eagle moves 4 times as fast, the eagle covers 4 hiker chunks of distance, so together they’ll travel 5 of those chunks.  1/5 of 250 feet is 50, so the hiker moves 50 and the eagle moves 4 times that.
