But Lucy is excited about the new science unit Miss Flippo has started: the states of matter. Lucy and her friends understand solids and liquids. They're easy. But gasses are more difficult to grasp.
When the class goes on a field trip to an orchard and Stewart Swinefest eats too many apples, and gets a serious stomachache, Lucy suddenly understands that even if you can't see gasses they can fill space and expand, and even make you move.
And with Stewart feeling better, she has a really great idea for her Harvest Festival costume, too.
The second book in a new chapter book series from IRA Children's Book Award-winner, Michelle Houts, Solids, Liquids, Guess Who's Got Gas draws on STEM themes and is aligned with curriculum guidelines to bring a love of science to young readers, inspiring them to start their own labs and explore their world.
