Answer 1

Start out with actual soybeans and/or canola (rape seed), produced by agriculture. Then show a sample of the food products made from them. There are many, especially with soybeans, including the cooking oils, milk, meat substitutes, cheese flour, bread, and etc. Another big contribution of agriculture today is energy production. Show how biodiesel is made from the oils of soybeans and canola to run your farm machinery, automobiles, heat your home, and animal housing on the farm. This demonstration can be a simple graph design on how to make your own biodiesel or an actual demonstration of you making the fuel. The following link will show you how you can make your own biodiesel.
