Cat. #908 Introduction to Plant Cell Culture
Complete in 60 min. plus several weeks for growth
For 10 Groups. Genetic modification of plants is a highly controversial area of biotechnology. Experiments in plants begin with establishing plant cells in culture. This involves de-differentiating plant cells to form plant
“stem cells”. In this experi- ment, students will establish cell cultures of African Violets from leaves. They will then use plant growth regulators to encourage root growth from the cultured cells, and produce a mature plant.

For 10 Groups. In this activity, students model how energy flows through a meadow ecosystem with an em - phasis on the concepts of trophic levels and entropy. This is an alternative lab activity that does not require growing Brassica rapa or rearing the invasive pest, Pieris rapae . Following the exercise, students will be able to explain how biological systems use free energy, predict the effects of community changes on energy and nutrient flow, and apply mathematical equations to describe key abiotic and biotic interactions.

Cat. #292 Dissolved Oxygen and Aquatic Primary Productivity
For 10 Groups. Dissolved oxygen levels are used to monitor the health and productiv- ity of aquatic ecosystems. In this kit, students familiarize themselves with the Winkler method by examining the relationship between temperature and dissolved oxygen concentrations. Using local water samples to examine primary productivity at different water depths, students can then observe the beginning stages of eutrophication.
Requires 2 hours.
