Column addition 4: Lesson 2: bats

Further Challenges

• There are many different species of bat. Some, like the giant golden-crowned bat are huge, with wingspans reaching 1 metre 70 centimetres. Others, like the Kitti’s hog-nosed bat are tiny, with wingspans of only 15 centimetres. Create a fact file on a particular bat species that includes lots of interesting number facts.
• Small bats, like the pipistrelles featured in the main clip, typically have a resting heart rate of between 200 and 450 beats per minute. This can rise to between 800 and 1,000 beats per minute when they are in flight. How does your heart rate compare to a pipistrelle bat?
