PLAY, LEARN, WIN: In Valence, you’ll assemble teams of Science Ninjas to build new molecules out of elements to earn points and win the card game! But beware - opponents can break down your Bases with Acid assaults! TEACH CHEMISTRY THE FUN WAY: If your kids are too young for the lab, but you want to get across basic and advanced chemistry concepts, nothing beats Valence. It's all here - from molecule formation, to acids and bases, to chemical reactions. Valence helps you meet STEM learning goals and is the ideal teaching tool for engaging both high achieving students and those struggling with chemistry concepts. SIMPLE START: If you can add to 0, you can play Valence. But the gameplay basics quickly lead to more complex interactions that spice things up and turn up the intrigue factor. Simple instructions and an online video quickly show players exactly how the game works. Then the fun – and learning – begin. The cool part? All the interactions that occur in the game can and do occur in real-world science. THE BASICS: Valence was created by a rocket scientist, an alternative energy expert, and a New York Times bestselling cartoonist, along with a bevy of scientific advisors. The game consists of 86 illustrated cards with a linen finish in a sturdy box, so it can stand up to the normal wear and tear that comes from 8-12 year-old kids in a classroom or home environment. All you need is a playing surface, two players, and the competitive spirit!
