In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

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 (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

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

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.
