Plant Science Bundle 2
kit #AG-S10
This bundle provides a savings of $60.75 and contains the following kits:
Seed Structure and Enzyme Actions (#65)
An excellent activity for middle school through college, this kit focuses on the structure of dicot and monocot seeds. Students first examine and dissect two representative types of seeds -dicotyledons and monocotyledons. After diagramming and labeling seed structures, they study the action of enzymes in the germination process and the fate of each part of the germinating seed. Finally, students draw conclusions about the enzymatic process.
Effects of Gibberellic Acid (#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 also allows them to experiment with growth behavior. It also provides for special projects and additional explorations.
Simulating Threshold Effects of Soil pH on Hydrangea Plants (#320)
Students model how hydrangea plants are affected by soil pH. The use of a simulation allows students to determine the effect of agricultural lime on hydrangea flower color. Students use the data obtained from the simulation to determine the positive and negative threshold doses for “agricultural lime.” They also reflect upon the results to decide whether they have sufficient data to recommend an optimal level of lime treatment to produce healthy plants with large, pink flowers.
