I’ve been trying to feed Aristotle’s interest in science experiments and found these interesting little science kits by Ein-O. They are RM35.90 each and I’ve seen them selling at Borders (certain outlets only), Art Friend (Midvalley), and the Kiosk Shop in Ikano outside Toys ‘R’ Us. Of course, you can also get them on Amazon.
We recently bought Aristotle the Ein-O’s box kit on Sound. It teaches children about the properties of sound, such as frequency, speed of sound, and sound waves. The kit contains materials to perform four experiments on the properties of sound:
- Box Guitar
- Pan Pipes
- Metal Bells
- Making Wavelengths
The first experiment Aristotle got to work on was the Pan Pipes. He had to measure out the straws and cut them to length.
Then he stuck them together in a row.
Blowing gently on one end of the pipes creates different “notes”. Aristotle learned that the shorter pipes created the higher frequency sounds and the longer pipes created the lower frequency sounds. To reinforce the lesson, I wanted to take him to a music store to observe the hammer action of a piano on the strings – how the longer strings are used to create the lower notes and the shorter strings for the high notes.
