Answer 3

I saw someone dissect an alive, conscious mouse at a science fair once, they pulled out its intestines to show the kids how long it is...

Answer 4

What I did in middle school and I won the science fair was determining what type of fabric was the best insulator of heat.  

What you can do is go get like 5 or 6 different types of fabric.  Examples: Denim, wool, cotton, polyester.  

You then need to get 5 or 6 identical glass jars with lids on them depending on the ammount of types of fabric you have.

You rap the jars with the fabric and tape them so that the fabric will stay snug around the jars.  You then pour boiling water into the jars and every 5-10 minutes check the temperature.

You'll need to drill a hole in the lids in order to drop a thermometer into in to jar to measure the waters temperature.

Do this for each jar for about 20-30 minutes and test each fabric 2x to verify your findings.

Make sure you keep everything controlled except for the types of fabrics on the jars.  In case you don't know what controlled means, it means keep everything the same.  So keep the water that your pouring into the jars the same temperature.  Use the same type of tape,  use the same type of jars and so on.

This is the expirement I did in middle school and I won.  It was a little time consuming but you can ask your parents for help.

Answer 5

since you are a "music lover", why not try to show the science of music?  example - how certain vibrations in the air caused by striking some object can be interpreted as a musical note. and how different notes put together in certain ways create chords and so on and so on.  example: line up several bottles and fill with water to increasing levels and demonstrate how density can change the vibration, etc.
