Water Sphere Lens
With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...
Exploratorium
Magnetic Pendulums
Passing a copper wire coil through a magnetic field influences another coil to also sway. It is with this demonstration that you can teach your physical science fans about electromagnetism. Note that the assembly requires about an hour,...
Exploratorium
Bernoulli Levitator
Two versions of this activity are presented for you to choose from when teaching about Bernoulli's principle in your physical science class. One is a hands-on activity, while the other would be best used as a demonstration during...
Exploratorium
Whack-a-Stack
Go wild as you hit a stack of wooden blocks to demonstrate Newton's first and second laws of motion. The blocks at the top of the stack stay put as you knock one at a time out of the bottom. Note, however, that you will need to visit a...
Exploratorium
Far Out Corners
Construct a three-dimensional optical illusion when your class is exploring vision and how the eye and brain work together. Three concave corners are mounted inside of a black box, but as a light is shined upon them, they appear to be...
Exploratorium
Falling Feather
Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...
Exploratorium
Eddy Currents
Make electromagnetic eddy currents evident with this demonstration. You will need to gather a few materials from the local hardware store and a strong neodymium magnet, but the visual value is well worthwhile.
Exploratorium
The Dipping Bird
If you have or want to order the dipping bird demonstration, it is useful for showing how evaporation and changes in the pressure of a closed system cause cyclical motion. After teaching about pressure, consider setting this little guy...
Exploratorium
Depth Spinner
Put a new twist on your collection of optical illusion activities. Affix the linked printable spiral to a drill, record player, or some other rotating tool. Have learners stare at the spinning disk for only 15 seconds and then look away....
Exploratorium
Cylindrical Mirror
Using flexible mirror-like paper, physical scientists experiment with images produced by curving it and looking into its reflective surface. They find that concave mirrors cause reflected light waves to cross and actually flip the image...
Exploratorium
Circles of Magnetism IV
Hang a strip of foil on a stand and form a loop out of it. Then attach the clips of a battery-operated circuit to the loop to see its sides repel each other. This simple demonstration is applicable and easy to add to your lecture on...
Exploratorium
Diamagnetism
If you are attracted to activities dealing with diamagnetism, here is a rare find that you will appreciate. With a neodymium magnet and a few common materials, move a pair of juicy grapes without touching them. Though the fruit is...
Exploratorium
Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...
Texas State Energy Conservation Office
Investigation: Waves and Whistles
Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...
Texas State Energy Conservation Office
Investigation: Water Wheel
Middle school scientists construct a working water wheel from an aluminum pie pan. Because of the sharp edges on the cut aluminum, this activity is for mature learners only. You could have your class compete to see whose wheel can lift...
Texas State Energy Conservation Office
Investigation: Splitting Atoms
In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

Pyramid Model
Seeking to derive the formula for the volume of a square pyramid, geometry learners construct six square based pyramids that, when pieced together properly, form a cube. Two short videos demonstrate the relationship between pyramid and...
Maths Revisions
Scaled Drawings
Your carpenters will enjoy learning scaled drawing techniques and applying their new knowledge to make some real-life scale drawings of gardens. Your carpenter scholars will be reviewing some basic skills in a warm-up section of problems...
Chapman University
Derivative of sin x
Direct and to the point (the slope at a point that is) describes this one-page proof of the derivative of the sin(x). The definition of a derivative using a limit is the first step in this sequential, algebraic, explanation of how the...
Chapman University
Graphs of the Sine and Cosine Function in Degrees
This bright, clear, graphic, display of the sin(x) and cos(x) functions spans the domain between -360 degrees and 360 degree. Use it as a poster, handout, presentation slide, or project it onto a whiteboard.
Chapman University
Graphs of the Sine and Cosine Function in Radians
This bright, clear, graphical display of the sin(x) and cos(x) functions spans the domain between -2 pi radians and 2 pi radians. Use it as a poster, handout, presentation slide, or project it onto a whiteboard.

Death Be Not Proud
Not dreadful, but mighty, this instructional activity for “Divine Sonnet X” (aka “Death Be Not Proud”) models for individuals how to recognize John Donne’s argument for why Death should not be proud and how to recognize the sonnet...

Epic Improvisation
Really? Rapping The Odyssey? Really. A discussion of the oral tradition of story telling and its links to Epic poetry sets the stage for a series of activities that encourage improvisation to integrate music into other classrooms....
