Bob McDonald wants your science question!

It's that time of year again.  Our science guru, Bob McDonald, makes his annual appearance on Manbridge One on One to answer your questions about science.

From the ordinary, "Why is the sky blue?" variety, to the imaginative, "is yawning contagious?" -- we want to know what question perplexes you about the world we live in.

We'll select a program's worth of questions from the submissions we receive, and Bob will get working to provide the best answer out there soon. So post your question to this page now.
