Craig: Here at the camp we are ____ about whales! Today you have been helping us with our whale research. First of all, we asked you
to find out some facts for a whale _______. What did you find, Sally

can grow to 100 feet long, and can _____ nearly 200 tons! There are two ____ types of whale: those with teeth, and those without.
Those without teeth eat very small organisms, whereas those with teeth eat fish and other larger sea animals. More than 70
species of whales have teeth.
Craig: Great! Then, we asked you to think about why we do whale research. Yes, Ben.
Ben: Firstly, it is to _______ how many whales there are. Whales are threatened by many ______, including climate change, ________,
and hunting. Secondly, it is to track where whales go, so we can understand more about them, like their life cycle. Lastly, we
know that whales are very _________. They communicate and hunt using complex sounds, and even sing and share songs. They
can learn by themselves and can _____ the things they have learnt to their young. We want to understand more about this.
Craig: Very good, Ben. And lastly, we asked you to go out with us and write a report of the work we do. Can you give us your report,
Luke
Luke: Yes. First, we followed a group of whales with the boat. Then we took pictures of their fins. Most whales have ________ 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 ________ path. Later, we created a database of their fins and locations. 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 ________ them in the future. Finally, we
________ other whale research groups around the world to share the information with them.
