Summer science activities by Don Rathjen, print version.
Books by Curt Gabrielson:
Sprotating Cylinder Cut 3/4 inch diameter PVC pipes , mark both ends and spin them and rotate them at the same time. Observe the patterns on the markings and discover what is happening.
Styrofoam Planes, investigate aerodynamics.
Frictionless Airpuck : use a CD and a balloon.
Blinky Lights Use inexpensive flashing LEDs to study motion.
Highway seismometer, record the bouncing of your car with a pen and clipboard on a bumpy road. http://www.exploratorium.edu/faultline/activezone/highway.html
Live eye on quakes http://www.exploratorium.edu/faultline/liveeye.html
Pasta Quake use spaghetti to model earthquake energy.
Exploratorium Seismometer explorations by dropping a bowling ball. Also done with headphones and audacity.
Explore the seismic motion as a function of ball drop height and distance.
Eric Muller's activities http://www.exo.net/~emuller/activities/index.html
Eric's earth Science Activities http://www.exo.net/~emuller/activities/index.html#earthscience
Who'se fault is it? Model quake location finding using people.
Seismic site http://www.iris.edu/hq/
Stereo Sound Use your ears to locate a sound when someone taps a tube.
How to use the free application "Audacity" to record and analyze sounds.
Dance of the Sound Wave Have 9 people dance to show the motion of air parcels in a standing sound wave in a tube.
Boyling Water Use a syringe to reduce the pressure on liquid water until it boils at room temperature.
Extrasolar planet detection Put a coin in a balloon , spin the balloon and coin and throw them into the air. Observe the motion.
Measure the brightness of the sun. Use a lightbulb and a grease spot photometer to measure the brightness of the sun.
Measure the power of the sun. Use a thermochromic sheet and a lightbulb to measure the power of the sun.
CD spectrometer Build a spectrometer with a compact disk and use it to observe fraunhoffer lines of sunlight reflected from white paper.(Never look directly at the sun with a spectrometer.)
"Seeing far infrared" You can feel far infrared radiation from hot objects with your cheeks and the backs of your hands. http://littleshop.physics.colostate.edu/activities/atmos1/FeelTheHeat.pdf
Seeing near infrared Your eyes can detect near infrared radiation. You are less sensitive to infrared radiation so you must block out visible light to allow your eyes to adapt to the dim perception of the infrared. http://littleshop.physics.colostate.edu/NSTA2010Documents/SeeBeyondTheRainbow.pdf
Coupled Pendulums, measure the frequencies of the normal modes and the beat between them.
Pendulum Snake, Assign 9 people, one to each pendulum and have them sing a note on every pendulum swing. The spatial pattern of swinging pendulums then becomes a musical pattern of sound.
Phase Pendulum Investigate the motion of a pendulum as it is driven at different frequencies above, below, and near its resonant frequency.
Recent Science activities
Blinky Light Use Inova Microlights as mini strobes.
Scanning probe macroscope Use a scanned cantilever to detect invisible forces.
