What is a robot? What is the difference between a robot and a human?

Create batteries from lemons and other fruit; discuss the context of energy and electricity.

Chemistry projects in an after-school program

A brief afterschool program activity for Pi Day.

A series of projects, videos, and models focusing on wind, weather, and weather stations. The primary activity is the construction of an anemometer, using an electronics kit and arduino (snapino) kit.

A random-poetry generator using an Arduino board and circuit based on the Snap Circuits "Snapino" set. Turn the crank on a generator, then pause, and random words appear on the computer screen to create a random poem. The faster you turn the crank, the more poetry you get. The program is pre-written, including an array of words for the random poetry, and participants can modify the program and array of words.

Five simple experiments that suggest the connection between atoms/molecules and electricity and magnetism. In our Science Wednesdays program we did this activity in a 90-minute session; but it could be expanded to allow more time for linking theory and experiment.

Craft / Science Wednesday project

A series of projects that introduce the concepts of acoustic and electronic music and sound. Copper-pipe xylophones are a highlight, along with electronic circuits that explore the conversion of electrical current to sound and sound to current.

Creating sundials; also creating models to illustrate the motion of the earth around the sun.
