Hi, I’m Oliver! Writing a book has made me kind of a celebrity around school – no big deal. But does that mean everything is perfect? No way! I’m still trying to figure out the usual stuff: school cliques, weird family, and how to finally win the science fair. While I may know EVERYTHING about space, there’s a lot to learn about the planet we live on, like: volcanic burps and bacteria farts how the Earth’s layers are like boba tea aliens! (Are we the aliens?) From bestselling writer and robotics engineer Jorge Cham, Oliver’s Great Big Universe: Volcanoes Are Hot! is the second book in a STEM-themed, diary-style series.
