Introduction

If you have ever built a tower with blocks, you have probably knocked it over—either on purpose, or by accident. Sometimes your tower gets too tall and wobbly, and you just cannot keep it standing! In this activity, you will learn about the trade-offs you need to make when building a tower that is both tall and stable.
