"Is there is any way of knowing what noises, if any, dinosaurs would have made?" asks Freddie Quinn, aged 8 from Cambridge in New Zealand. From Jurassic Park to Walking with Dinosaurs, the roars of gigantic dinosaurs like T.Rex are designed to evoke fear and terror. But did dinosaurs actually roar? And how do paleontologists investigate what noises these extinct animals may have produced? Hannah and Adam talk to dinosaur experts Steve Brusatte and Julia Clarke to find out. Plus Jurassic World sound designer Al Nelson reveals the strange sounds they used as dinosaur noises in their Hollywood blockbusters. Send your questions for next series in to curiouscases@bbc.co.uk.

In the second installment of our double episode on the Moon we ask what life would be like if we had more than one Moon. From the tides to the seasons, the Moon shapes our world in ways that often go unnoticed. And, as we'll find out, it played a vital role in the creation of life itself. This week we celebrate the many ways the Moon and the Earth are linked. If one Moon is so great, why not have two? We discover why multiple moons could spell disaster for our planet, from giant volcanoes to cataclysmic collisions. Featuring astronomer Brendan Owens from the Royal Observatory Greenwich and physicist Neil Comins, author of 'What if the Earth had two Moons?'. Presenters: Adam Rutherford, Hannah Fry Producer: Michelle Martin

A double episode to mark the 50th anniversary of Apollo 11, and the first humans to walk on the Moon.

I'll be over the moon if you can help me solve this mystery.” In this first episode, Hannah and Adam look at how the Moon was formed and why we only have one. Featuring Maggie Aderin-Pocock space scientist and author of 'The Book of the Moon' and cosmic mineralogist Sara Russell from the Natural History Museum.

“We play many musical instruments in our family. Lots of them produce the same pitch of notes, but the instruments all sound different. Why is this?” asks Natasha Cook aged 11, and her Dad Jeremy from Guelph in Ontario, Canada. For this instrumental case Hannah and Adam are joined by the Curious Cases band - Matt Chandler and Wayne Urquhart - to play with today's question. Bringing the science we have acoustic engineer and saxophone player Trevor Cox. Plus materials expert Zoe Laughlin demonstrates a selection of her unusual musical creations, including a lead bugle.
