Spring has sprung (finally!) so it is the perfect time to plant something and watch it grow! In this spring science experiment you will make your own plant pot with a viewing window so you can watch the roots grow.

You will need:

• An empty juice carton
• Scissors
• Duct tape
• Superglue
• Soil
• Seeds – your choice! Eg. carrots.
• Clear plastic eg from a plastic wallet or something stronger

  

Method:

• Wash out the juice carton.
• Cut off the top, down the sides (on one side) and across the bottom so there is 1 inch left around the edge. *May require adult to help*
• Measure and cut the plastic to size, including the 1 extra inch to stick to the carton!
• Put superglue around the edge of the “window” on the carton and stick the plastic down. *May require adult to help*
• Place duct tape over the edge of the plastic to ensure it is water-tight.
• Add soil until it is nearly at the top of the carton.

  

• Plant your seed 1/2 an inch away from the window.
• Water your plant.
• Place the top of the carton back on for a 1-2 weeks – most plants germinate better in the dark!
• Check the soil to ensure it stays moist.
• Watch the roots grow!

Extra bits:

• Why not add a ‘window’ on both sides?
• Don’t stop at one, make more and plant lots of different things! Do the roots look different?
• Why not decorate the carton?
