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

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

This lab activity has learners create a pendulum with a one-second period.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

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

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

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

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.
