Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this activity, learners explore how engineers work in a team to solve problems.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.
