Growing Popcorn Investigation - Fair Testing

We began an investigation on Friday with growing popcorn seeds.  Investigation: How do Popcorn Seeds Grow the Best?
Things We can Change or Vary: Depth of the seeds, types of seeds, light or dark, warm or cold, water or no water
Things We can Measure: Length of stalk, how fast it grows, how many grow

Today, Monday, 5 March we put a piece of paper towel into four plastic cups.  Next we put six seeds down the outside of each paper towel. Then we added two dessertspoons of water to each cup. Finally we placed each cup in its position (ie warm, cold, dark or light) .




This is our Investigation
My Question: Will Popcorn grow better in the Light or Dark?
I will Change:  We could choose from putting one in dark and one in light or one in warm and one in cold.
I will Measure: We decided on 'How High the Plant will Grow'.
I will keep the Same: Same amount of water, seeds from the same packet, same type of cup, same type of paper towel, same amount of water, seeds on outside of paper towel.

We will keep you informed of our popcorns progress.
