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 construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

In this activity on page 6 of the PDF, learners use glue instead of glass to create artwork that can be hung in a window.

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

In this activity, learners will trick out their bike with crafts and flair. Learners will explore symmetry, cause and effect and design through this activity.
