Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
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.
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.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
Good Vibrations
Source Institutions
In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.
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.
Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of
Enzyme Action
Source Institutions
In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.
Anti-Gravity Mirror
Source Institutions
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.
Smelly Balloons
Source Institutions
Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.
Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.
Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
Melts in Your Bag, Not in Your Hand
Source Institutions
In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
Dealing Signals
Source Institutions
In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.
Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.
