EE Simple Machines

Explore the science of how things work with our Simple Machines Unit Study Kit!

Centered around the book Simple Machines by David Adler, this unit invites kids to dive into the world of mechanics as they explore the six types of simple machines: levers, wheels and axles, pulleys, inclined planes, wedges, and screws.

Your kids will learn how simple machines help us do work—and how they’re all around us in everyday life—through engaging, build-it-yourself activities like:

• Explore and test how a lever works
• Build and use a pulley
• Experiment with inclined planes
• Investigate wedges and screws
• Learn how wheels and axles reduce friction
• Complete STEM challenges using simple machine principles
• Design and build a compound machine

Each lesson includes a focused hands-on project that makes early physics concepts come alive in tangible ways. This type of project-based learning encourages critical thinking, creativity, and problem-solving while helping learners apply what they’ve discovered in meaningful ways.

This unit study includes 25+ activities, organized into eight easy-to-follow, open-and-go lessons. Schoolhouse Discoveries hands-on unit studies are designed for homeschool families and can serve as a core Science and Social Studies curriculum for grades K–4 and a supplement for 5-6th. Each unit also weaves in Language Arts, Math, Art, STEM, Sensory Play, Cooking, Health, and Movement.

By using multiple themed kits throughout the year, families can build a complete, well-rounded curriculum rooted in hands-on, family-style learning.

Have more than one child participating? 
Sibling Add-Ons are now available as an option when you order your kit. Add one for each additional child to receive another set of printed activity pages and extra supplies (not a full duplicate kit). It’s the easiest way to get everyone learning and creating together—without doubling your prep.

Perfect for homeschoolers, co-ops, or those using charter school funds or educational scholarships.
