Notes
Activity 3
After that, we gave the group of whales a name, and each member a number.
They will be added to the directory so we can identify them in the future.
Most whales have slightly different fins and marks, which can help us to tell them apart.
Meanwhile, we also noted their location, so we can track their movements and plot their migration path.
Then we took pictures of their fins.
Finally, we contacted other whale research groups around the world to share the information with them.
First, we followed a group of whales with the boat.
Later, we created a database of their fins and locations.
Circle the sequence words before listening again

B：What did you do afterwards
A：We created a database and gave each whale a name and number. Finally, we shared our information with other whale research groups
around the world.

Purpose
Activity 6
For our trip, we would like to go to the Shanghai Ocean Aquarium， whose theme is “Spanning five continents by a connection of water”.We can first visit the special exhibition of saving sharks.Then we can go to see the seahorses whose number declined greatly for the past decade. However， most people do not know much about seahorses at all.I think we need to raise awareness about seahorses and marine conservation in China.The last spot will be The Chinese Pavilion, which displays the aquatic organisms and bio-system in the Yangtze River and some national endangered rare aquatic creatures, like Chinese alligator and Chinese Sturgeon.
