Botany—Lab Activities, continued
Characteristics of Algae—
Student Laboratory Kit
Explore the realm of photosynthetic algae and
increase student microscopy skills with this kit. Students compare and contrast living and preserved species from the groups Chrysophyta, Euglenophyta and Chlorophyta and investigate characteristics of both multicellular and colonial algae. The laboratory begins with a thorough inspection of prepared microscope slides. After examining the internal and external features of the preserved specimens, students observe living samples of the same organisms to study their behavior as well. A great introduction to a pond or marine water classification lab!
Complete for 30 students working in pairs. Compound micro- scopes and live cultures are required and available separately.
Sodium Alginate Photosynthesis—
Student Laboratory Kit
By: Pam Bryer, Bowdoin College, Brunswick, ME
Use this compelling method to quantify the rate of photosynthesis! With spherification, the process of trapping a liquid inside a gelatinous sphere, students make their own algae spheres. Students will be completely engaged as they see their slurry of algae coalesce into perfect spheres. Expose the spheres to different conditions and measure the productivity of the algae inside. These spheres are permeable to gases, making them great for investigations. Use a variety of methods to measure changes in the gas concentration and pH. This method makes is easy to control the amount of algae in the system so that trials can be compared.
Complete for 30 student working in pairs.
Tree Growth Study—Super Value Kit
By: The Flinn Staff
Trees contain some of nature’s most accurate records
of the past. Students will unlock these historical mysteries and uncover environmental trends by studying actual tree round samples. Hardwood versus softwood trees, good years of tree growth versus poor years and the tree ages will be determined. Complete with 5 sets of three different types of tree round samples—15 samples in all—detailed student and instructor notes and all other required materials.
Super Value Kit is complete for 15 student groups. Materials are reusable.
Tree Ring Dating Simulation—
Student Activity Kit
By: The Flinn Staff
At 4,723 years old, “Methuselah”—a bristle cone pine tree located in central California—is believed to be the oldest known living thing on Earth. How is the age of a tree determined? Introduce your students to dendrochronology, the study of past patterns of plant growth, with the very involving materials in this kit. Simulated tree core samples, coupled with climatic data, provides a real thought-provoking activity for your students as they determine the age of various trees. Once this dry lab is completed, examining real tree borings or tree cross-sections will become very enjoyable and productive for your students.
Masters for copying all the student materials are provided so that all of your students can complete this activity individually.
