Students perform experiments to determine the nutritional needs and physical space requirements for slime mold to survive. After formulating hypotheses, they seal the petri dishes and set up the experiment along with two controls. After five days, they track their results on diagrams and determine if their hypotheses were correct. Full Review »

Students study how environmental engineers monitor water quality. They use environmental indicators to determine the quality of stream water in their area. They count the number of macroinverabrates and use the information they collect to design a scale that rates how good or bad the water is. Full Review »

Students participate in a two-part lab that takes place in the field and the laboratory. They work in pairs to compare fauna in crevice and non-crevice habitats and between vertical walls and overhang microhabitats among coastal rocks. Students then return to the lab and mount samples for further observation. Full Review »

Students identify and experiment with dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their region. Students determine the average age of the trees in their schoolyard, investigate any years of poor growth, and draw conclusions about the reasons for the years of poor growth. Full Review »

Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for students who are familiar with the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation (bacterial infection, plasmid vectors, marker genes, selection medium, and enzyme activity assays).

Students examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different classes of plants, vascular and non-vascular plants, ferns, and seed groups. Full Review »
