Interesting science experiments are likely going to get the best grades. Judges are used to seeing all the same old projects and if yours is interesting it will definitely stand out. There are endless topics to choose from, so the first step is to narrow down your choices and choose a topic that interests you. If you are bored with your project, it will show in your work!
One interesting science experiment is to make a shrunken head out of an apple. To do this you will need one large apple, a knife, salt, lemon juice and water. First, you will need to skin the apple with a vegetable peeler, and then you can use the knife to carve the facial features (eyes, mouth, ears, nose, etc. ). Be sure to make them quite large as the apple is going to shrink considerably. When you are done this, place the apple in a solution of ½ cup of salt mixed with four to six cups of water and add 2 teaspoons of lemon juice, which is meant to keep it from oxidizing.
Let the apple head soak for 24 hours before removing it from the liquid. Use a paperclip to pass a string through the apple from top to bottom, and then hang it in a cool dry place for about two or three weeks. When it is ready, you can sew the mouth together with cotton strings and attach some fake hair to make it look more realistic. There you have it! Your very own shrunken head.
