Default How many seeds should I use for this experiment?

I've grown seedlings using a *clear* plastic cup, putting wet paper towel on the inside of the cup. (for your experiment, you would soak the paper towel with your different solutions) Then put the seed in between the paper towel and the cup. That way you can see the seedling grow over time. You can measure growth by measuring the length of the root with a ruler (outside the cup, without having to disturb the seedling), and also after how many days the leaves appear. Having more than one seed for each condition is good, as it is more scientifically accurate to average how fast the seedlings are growing.

Everyday, you can wet the paper towel with a fixed amount of the appropriate solution.

I hope that helps!
Hi, Biogradstudent! Im interested in trying out this experiment - how may seeds should I use? 5, 10, 20, 100?
