Rubber Band newton Scale
Source Institutions
In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

Rutherford Roller
Source Institutions
In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

Inverted Foucault Pendulum
Source Institutions
In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.

Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

Magnetic Shielding: Magnetic lines stop here
Source Institutions
Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

Proprioception: Wiggle where you're at
Source Institutions
We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

Michelle O (formerly Vanna)
Source Institutions
We don't normally view people upside down and so our brains aren't accustomed to it.

Radiohead
Source Institutions
When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Circles or Ovals?
Source Institutions
This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

Afterimage
Source Institutions
In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.

Condiment Diver
Source Institutions
In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

Phantom Phlame
Source Institutions
In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

Personal Time Line
Source Institutions
In this activity, learners work in groups to create a time line representing significant moments in their lives.

Piezoelectric One-Way Remote
Source Institutions
In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.
