Part 1
The weight of a data-logger should be less than ___ - ___ % of an animal’s weight.
3 - 5 %
What is the Antarctic in Japanese?
南極大陸
In the research, did the cheetahs hunt their prey at top speed?
No, they did not.
Usually, which kind of animals can stay underwater longer? Big or small animals?
Bigger animals.
"Generally speaking, the bigger marine animals are the longer they can stay underwater."
What state in the USA is Amaris from?
She's from Kentucky.
What is bio-logging?
It is a new scientific research method.
Where do seals hunt for food: in shallow or deep water?
They hunt more than 200 meters below sea level, so, in deep water.
What speed can cheetahs run up to (km/hour)?
They can run up to 100 kilometers per hour.
Which large animal can stay underwater for two hours?
Elephant seals. They weigh more than 2 tons! (1815 kg)
What's Talita sensei's favorite anime?
Attack on Titan / Shingeki no Kyojin
What two (2) things should a bio-logger NEVER disturb ( 邪魔する／妨げる) on an animal?
The bio-logger should never disturb the animal's 1) movements or 2) activities.
What's "hypothesis" in Japanese?
仮説 kasetsu
What country did researchers study cheetahs in? (Bonus: what continent (大陸) is this country in?)
They studied cheetahs in Namibia, which is in Africa.
What did researchers record in order to uncover how a penguin's body works?
They recorded penguins' heart rate while swimming.
Where is Talita sensei's mom from?
From Brazil.
What are two examples of the kind of information a bio-logger can collect?
Location, body temperature
ALSO: speed, heart rate
Why were the mother seals swimming in the shallow water?
They were swimming in shallow water to teach their babies (pups) how to swim.
What must we do to confirm our assumptions?
We must collect a large amount of data and analyze it scientifically.
What was the penguin's heart rate when it was about to reach the surface again?
27 beats per minute (bpm).
How did the researchers know that the mother seals were teaching their babies to swim in the shallow water? (どんな証拠を見つけました？)
1) The pups (babies) were swimming at the same speed and depth as their mothers.
2) The data-logger showed images (pictures) of her baby following her.
In the research, why didn't the cheetahs run at top speed to catch their prey?
The research happened in the bush, where prey couldn't run at full speed. Therefore, the cheetahs didn't have to chase at full speed, either.
How do penguins manage to stay underwater for a surprisingly long time?
They use oxygen efficiently by slowing down their heart rate.
