The philosophy of designing experientially-based
non-formal SET curriculum materials brings into
focus the ways in which teaching materials are
created and organized.
Effective SET curriculum design requires:
When you hear the rubber band vibrate the same thing you see in the water is happening in the air. The air carries the vibrations as waves through the air, or other medium, to your ears. The vibrating waves in the air cause the parts of your middle and inner ear to vibrate causing your brain to perceive the waves as sound.
Try the stretching the rubber band over a metal pie pan or a metal pan lid.
What other kinds of musical instruments can you think of and how do they make music?
2. Cut two small pieces of straw, each about 1 inch to 1-1/2 inches in length.
3. Put one of the small straw pieces underneath the wide rubber band, about a third of the way down from the end of the stick.
4. Take the other craft stick and place it on top of the first one.
5. Wrap one of the small rubber bands around the end of the stick a few times, about ½ inch from the top, on the same side where you placed the piece of straw. Make sure the rubber band pinches the two craft sticks tightly together.
6. Put a second small piece of straw in between the two craft sticks, on the opposite end, approximately a third of the way down from the top of the stick. This time, don’t put the straw underneath the wide rubber band; place it on top of the rubber band, in the middle of the two sticks.
7. Wrap a small rubber band around this end of the craft stick, about 1/2 inch from the end. When you’re done, the two ends should be pinched and there should be a small space between the two craft sticks created by the two pieces of straw.
8. Put your mouth in the middle and blow! Remember to blow through the sticks, not through the straws.
9. Move the straws closer together. Does the sound
Now take the straw and flatten one end of the straw. You can use the scissors handle and press the straw flat to create a crease on either side.
Now try different size straws and different size cuts recording all the dimensions.
Now that you have made your own musical instruments and tested different sounds to see what sounds pleasing together it is time to make some digital music. The software has been downloaded that lets you make music and change it on a computer.
“Technology lets you share ideas. By sharing and learning and teaching, you expand your imagination.”
