Solutions

1:A - An adult giant panda eats somewhere between 12kg and 38kg of bamboo a day. They mainly eat bamboo shoots, leaves and stems – delicious! It’s not super-nutritious which is why they need to eat a lot. , 2:B - Your voice sounds different in your head because of “internal sound”, made by sound waves from your voice vibrating in your skull, mouth and body. As these vibrations travel through bone, they become lower in pitch, so your voice sounds different to you from how it does to other people., 3:C - Both those movements use the same part of the brain, which tries to process and send signals for two different movements at the same time – it gets confusing! If you practise, it gets easier, as you train your brain to treat it as one task., 4:B - In our solar system, there are eight planets orbiting the sun, but astronomers have found more than 5,000 that orbit stars other than the sun., 5:D - Crocodiles swim by propelling themselves with their strong tail swinging side to side in a snake-like motion, and by using their webbed feet for steering.
