What type of soil do plants need to grow well?

Kids need to understand that, once the soil has become sand, plants can’t grow properly. 

Planting seeds in 2 pots to keep in the classroom. 

The pots are used for comparing the growth of the same species of plant (basil, parsley ect.): 

  • 1 pot with healthy soil, the other pot with pure sand 
  • approximately the same number of seeds are put in the pots
  • both pots are kept in the same conditions of watering and lighting 
  • once seedlings grow, kids can observe the difference of abundance of plants in the healthy soil pot
