In this STEM lesson, students explore the effects of gravity, friction and air resistance upon acceleration when they design their own bobsleds.

In this STEM lesson, students use their knowledge of potential and kinetic energy, and explore forces and motion to place a ball into the center of a 6-foot diameter circle.

In this STEM lesson, students will use their knowledge of potential and kinetic energy to build fun contraptions that will make a ball move and hit a target.

In this STEM lesson, students draw upon their understanding of buoyancy and density, as well as potential and kinetic energy, to design and build a floating vessel with its own propulsion system that will carry cargo across a wading pool.

In this STEM lesson, students will explore the movement and properties of sound waves as they design a listening device that will allow them to listen to the sound generated by a specific object inside of a box.

In this STEM lesson, students explore the properties of magnets by designing a device that can move as far as possible using only magnets to move it, and then design a machine that will stay in motion for the greatest period of time.

Inspired by the whimiscal drawings of Rube Goldberg, in this STEM lesson, students will use their knowledge of forces, work, simple machines, and conservation of energy to design and build complex contraptions to complete a simple task.

In this STEM lesson, students design a pumping device that will effectively pump fluid through a given cardiovascular system.

In this STEM lesson, students explore the concepts of forces and motion as they design protective devices that will enable their egg rovers to safely land on a surface after being dropped from a designated height.

In this STEM lesson, students will create and test a wind dispersed seed that they have designed themselves.

In this hands-on STEM lesson, students will learn the requirements of making an electrical circuit and will design a switch to control a circuit. They will also investigate the differences between series and parallel circuits. They will apply their knowledge in a final task to design and build a signaling device.

In this STEM lesson, students explore how simple machines can make "work" easier while they design a device to retrieve their sibling from a tree house that has lost its ladder.
