Why is it important to explore, in your opinion
How would you like to explore our world Why
AFTER YOU WATCH
Of the explorations in the video, which seems the most important Which seems the most interesting Why
The most important is the one with the butterflies because butterflies are easily affected by climate and pollution, and so their lives can tell us a lot about how the world is doing.
AFTER YOU WATCH
Of the explorations in the video, which seems the most important Which seems the most interesting Why
The most interesting one is the cave diving where they found the animal bones. It just seems so strange and mysterious, and one would not expect to find bones there.
AFTER YOU WATCH
Why is it important to explore, in your opinion
I think it is important to explore because exploration is a part of human growth, both as an individual and society. Through exploration, we develop ourselves. Our interests and curiosity cause us to learn, to improve, and to be better.
AFTER YOU WATCH
How would you like to explore our world Why
I would like to visit places with my camera and take photos of interesting places and people, as I enjoy photography and love travelling and finding out about new cultures.
HOMEWORK
Do some further research on one of the exploration activities at the end of the video: ice skating, snorkelling and spelunking.
Make a poster to demonstrate your findings.
