A Plant Maze

Plants need light to make their food so that they may grow. Sometimes plants can even grow in all different directions so that their leaves can reach sunlight. You might have seen plants or trees that grow with bends and turns. In this experiment we will see how plants grow in the direction of the light.

You will need:

  • 2 pieces of cardboard
  • Pot of soil
  • Water
  • Shoebox
  • Bean seed (soak it overnight)
  1. Cut a rectangular hole in one end of the shoebox
  2. Cut a rectangular whole in each piece of cardboard
  3. Plant the bean in the soil. Make sure you water it!
  4. Stand the shoebox upright so that the hole is on top. Place the pot at the bottom and then place a cardboard piece above the plant. The hole in the cardboard should be on the opposite side of the plant.
  5. Put the lid on the shoebox and keep it in a light, warm place. Remember to water your plant.
  6. Let the seed grow through the first hole. When it has done that, place the second piece of cardboard in the shoebox. This second hole in the cardboard should be on the opposite side of the first hole.
  7. Place the lid back on and let the plant grow for a few more days. Check to see if the plant grew in a different direction towards the light.

Plants need light to make food so they will grow in the direction of where the sunlight is. Sometime, the light is not directly above them. In this case, plants will grow off to the side with bends and twists to reach the sunlight.
