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 also allow them to experiment with growth behavior. It also provides for special projects and additional explorations. This kit is designed for 30 students to work individually.
