Background
Photosynthesis is a process that involves plants, air, soil and sunlight. Plants produce sugar and oxygen and take from nature CO2 and H2O. They need chlorophyll in order for all this to happen. Because of this, cycles of life are possible on earth. How does this happen? Can you think of one cycle of life? In the shoreline, how is seaweed related to this cycle (a trip to the seashore anywhere in the area is a good way to illustrate the work in the classroom; Lighthouse Park is excellent for this activity)?
Your Task
Your task is to find a cycle of life in the shoreline. Think about the relationship, if any, between your cycle of life and seaweed. Use an organizer or a web. Write a paragraph about your findings. Make drawings.
Materials
-
Seaweed
-
Magnifying glass
-
Microscopes
Audience
Students and teachers in the classroom.
Purpose
To find out about the structure and composition of seaweed and how it fits in the cycles of life in the seashore.
Procedure
Make a team of three or four students. Take two different samples of seaweed. Analyze it under the microscope and magnifying glass. Make observations using your senses. Compare and contrast. Make drawings of the seaweed under the microscope, under the magnifying glass and without a magnifying aid.
Applications
Once you have your findings, how can we apply this information in real life?
