Effects of Gibberellic Acid

Kit #68

This fascinating lab exercise studies the effects of gibberellic acid on plants. Gibberellic acid, when applied to plants, causes them to respond differently and at times unpredictably. This is an excellent activity for introducing your students to the study of growth hormones and allowing them to experiment with growth behavior. It also provides for special projects and additional explorations.
