Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.
Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Touch the Spring (Lightbulb)
Source Institutions
In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Laser Lissajous: PVC Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Fireworks!
Source Institutions
In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.
Transformation of E. coli Using Green Fluorescent Protein
Source Institutions
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.
Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
Vanishing Rods
Source Institutions
This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.
Parabolas: It's All Done with Mirrors
Source Institutions
In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.
Diffraction
Source Institutions
In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.
Glowing Pickle
Source Institutions
In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
LEGO Orrery
Source Institutions
Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.
Laser Lissajous: Binder Clip Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
What does Color have to do with Cooling?
Source Institutions
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.
Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
