Plant Cloning: Propagating Cuttings

In this essential life science activity, students supply plants with different amounts of key macronutrients and observe how the presence or absence of these chemicals affects plant growth. The Lab-Aids Mini Greenhouse was designed for small, controlled investigations and this easy-to use apparatus allows students to readily observe plant physiology, particularly root development. Additional...

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...

Your students gain a complete understanding of the process of starch digestion by plant enzymes, using this individualized lab activity. Seeds that have been soaked overnight are used to illustrate several concepts.

This simple procedure permits students to obtain impressive results in differentiating many cell types and tissue structures. It provides excellent discrimination among structures with a high density of different cell types such as root tip or bud. Students hand-cut, mount and stain a section of material. Their observations become more meaningful since they provide...

Cell Differentiation is a process by which development of a living organism is achieved. Through a series of progressive changes, a generalized cell transforms into a specialized cell. The more specialized the cell becomes; the less likely it is to divide. After the seeds germinate, students prepare slides, then watch living material differentiate before...

In this engaging and fun kit, students learn how to differentiate between plant food stored as a simple sugar and food stored as a starch. Using a step-by-step procedure, students first dissect the seeds, and then treat them with reagents. This helps to determine the quantity and location of the sugar and starch. The...

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...

This simple, step-by-step lab activity provides a sense of realism and participation that commercially prepared slides or illustrations can't possibly duplicate. Students prepare slides using pre-cut monocot and dicot plant cross sections and macerated stem tissue. After staining and mounting the samples, students then view their slides through a microscope. Students use clearly...

In this series of two activities students explore inherited traits. They use LAB-AIDs simulated corn ears and Punnett squares to gather data on, interpret, and predict the probability of traits being passed from parent to offspring. They then read about “survival of the fittest,” natural selection, selective breeding, and the relationships between...
