In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.

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

In this activity, learners explore how musical instruments are engineered.

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 design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
