Start to STEM Curriculum Program
Comprehensive equipment pack for 24 students
O B Start to STEM Simple Machines Kits All the equipment needed for hands-on lessons in force, work, and mechanical advantage! Students explore levers and pulleys through the tabletop- sized LearnLever ® Mini Levers, LearnLauncher ® Mini Catapults, and ForceCourse ® Mini Pulley Systems. In InclineInvestigation ™ , students can use spring scales to determine how ramps are used for mechanical advantage. Use included soft wedges to learn about minimizing force to separate items. Lastly, explore wheels and axles through different-sized gears to calculate gear ratio with RatioReveal. Kit includes equipment, manual, and a live virtual training. Lessons outline 10 days and are scalable by grade level. Full contents online. Aligns with NGSS. 24 students.

Learning Objectives • Be able to locate the fulcrum on a lever. • Understand the relationship between the location of the fulcrum and the force it takes to lift a load.

• 4 mini levers • 72 beanbags
SET UP • The lever arm is the piece with the orange and green cups already attached. It has holes underneath which represent the different fulcrum locations possible. • Connect the lever arm to the fulcrum (blue base) with the black hook and loop strap. • Adjust the fulcrum location by moving the lever arm horizontally and aligning the fulcrum base with a different hole on the lever arm. • Adjust the tightness with the strap so that the cups stay upright during the lesson.

TEACH • Identify the orange cup as the force and the green cup as the load. • Begin the experiment by placing the lever on the fulcrum point closest to the green cup. • Place 5 beanbags in the green cup, representing the load. • One by one, add beanbags to the orange cup to determine the amount of force required to lift the load. • Remove the beanbags from the orange cup, but keep the beanbags in the green cup. Move the lever so the fulcrum is one spot farther away from the load. • One by one, add beanbags to the orange cup to determine the amount of force required to lift the same load with a different fulcrum point. • Continue the experiment by moving the lever so the fulcrum is one spot farther away from the load.
REFLECTION QUESTIONS • How many beanbags are needed to lift the load when the fulcrum is closest to the load? • How many beanbags are needed to lift the load when the fulcrum is two spots away from the load? • As the fulcrum moves farther from the load, is more or less force needed to lift the same load?
