You will need:
7. Straws 1 and 4 should be closest to the ends of the craft stick, while Straws 2 and 3 should be in the middle.
8. With an adult to help you hold the straws in place, put the second craft stick on top of the first one, creating a sandwich with the pieces of straw between the craft sticks.
9. Secure this sandwich by wrapping a small rubber band approximately a half inch from each end of the sticks. The ends of the sticks should be pinched together with a small space between them created by the straws.
10. Hold your instrument like a sandwich, with one hand gently holding each end. Try to keep your fingers on the small rubber bands on either side.
11. Blow through the opening between the craft sticks as though it is a harmonica (do not blow through the straws!).
What sound do you hear? Do you feel anything in your hands as you blow through your instrument? Do the craft sticks vibrate or feel different when you play a sound? If you move the straws what happens to the sound? Does the sound change?
1. Get some white bowls or a mug and decorate however you want using permanent markers. (Be careful not to get any on you.) Once you have finished, you can paint over your design with PVA glue to help protect the design.
2. Collect some rocks and get painting. What incredible design ideas will you come up with? Once you have finished you can paint over your design with PVA glue to help protect your design and make it last longer.
Don't worry when you paint over your design with PVA glue. It will turn white for a little while and hide your beautiful design but when it dries, it will be clear and shiny to show off your design.
Do you have the skills to cook up a storm in the kitchen? Use the Olympic skills record to help you get cooking.
