This is an activity exploring color and color mixing.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

Many people get water from a source deep underground, called groundwater.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this activity, learners investigate the effect of heat on a reaction.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
