With the help of color play dough we can make a cool science working model.
There are four layer of earth.
- Crust
- Mantle
- Outer core
- Inner core
Crust is a outer most layer of earth. This the layer in which we are living. It is said that thickness of crust is from 8km to 32km.
Mantle is the second outer layer of earth. This is the most thickest layer of earth.
Outer core is third layer of earth surface. It is said that thickness of outer core is about 2,200 km.
Inner core is the fourth layer of earth surface. It is the inner most layer. This is the hottest among all surface. Its thickness is about 1250km.

6. Floating Egg Experiment :
Floating egg science experiment is another cool science fair ideas. This experiment helps us to learn about density.
Three glass with about to full water are kept in a place.
Case A: Glass a contains only water. There is no addition of any salt. When we put egg then egg completely sinks in water.
Case B: Glass b contains water plus two spoon salt. As we put egg then this egg partially sinks in water.
Case C: Glass c contains water plus four spoon salt. When we put egg then egg floats in this mixture.
This all helps us to define and understand about density.

7. Convection Current Working Model :
Convection is defined in our first science fair ideas in pinwheel experiment.
This science working model is made with materials like cardboard, clear plastic, candle, etc.
When we bring source of smoke above one hole. This smoke enters through that hole and escapes from another hole.
This is due to convection current. When we place smoke source at hole one. This smoke (co2) being heavier then other gas enter through that hole.
As we light up the candle this smokes escapes from another hole. Since it becomes lighter.
