Life Size: What's in a microbe?
Source Institutions
In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
Hole in Your Hand
Source Institutions
Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.
Lagging Sound
Source Institutions
In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
Far-Out Corners
Source Institutions
Are there boxes, is this an illusion, or is this real life Q-bert? Illusions are always fun to build especially when you can build them.
Look Into Infinity
Source Institutions
Learners use two mirrors to explore how images of images of images can repeat forever.
Memory Solitaire
Source Institutions
In this online game, learners practice memory recall. They are shown a collage of pictures for two minutes, then have to write down everything they remember and check how they did.
Ambiguous Cube
Source Institutions
In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.
The Game of Life: Stem Cell Edition
Source Institutions
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
Your Sense of Taste: Discover the real taste of candy
Source Institutions
Your tongue can sense about 6 different flavors (salty, sweet, bitter, sour, umami/savory, and fat), but your nose provides a lot more "taste" information than you realize when you eat.
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Soap Film on a Can
Source Institutions
The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.
Depth Spinner
Source Institutions
Experience a spinning spiral...you won't be hypnotized, but you'll see what happens when you look away. It's like getting off a merry-go-round and everything keeps moving.
Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.
Jacques Cousteau in Seashells
Source Institutions
Up close, an array of dots could look random, but take a step back, and an image forms. By tracing over an image, learners can create their own dot based image.
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.
Vegetable Revival
Source Institutions
In this activity, learners use food scraps from the kitchen to grow new vegetables.
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.
Salty Pits
Source Institutions
In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.
