You could also see the effect of adding salt or sugar to the bags or perhaps light vs. dark. Which condition produces the fastest bean growth? It’s all about variable testing!

Why Does This Happen

Find out for yourself!

Growing your own beans in a PET bottle can be a lot of fun, but you can also use these beans to investigate factors that affect plant growth. Try setting up different bottles and changing one thing to see the effect (eg. the amount of water or light they get or adding salt to the soil). Changing one variable and seeing the result is part of the scientific method and we strongly encourage it!
