In conclusion are hypothesis was right, gravel and soil grew the most.

 The plants that grew in the grass seeds died in 4-6 days.  The plants that grew in soil grew very fast.  The plant that grew inside the gravel also grew pretty fast.  The plants that grew inside of the sand grew but not as fast as the gravel and soil.

 We all have slightly different soil depending on where we live, from dry sandy soil to heavy, wet clay.  Many plants just cant cope with the extreme conditions these soils provide.  It is also a good idea to consider your soil pH(acidity or alkalinity) this will affect certain plants to.
