Instructional Procedures:
1.
Pass out the
PLANKTON SURVEY – Lessons 1, 2, and 3 (one per student).
Have students check the pre‐survey
box and answer the questions (allow 5 minutes). After Lesson 3 is completed, the students will answer these
same questions as a post‐survey. A TEACHER ANSWER KEY is provided for your convenience.
2.
Distribute a STUDENT WORKSHEET – PowerPoint – Lesson 1: Introduction to Plankton to each student. Play
the narrated PowerPoint presentation to familiarize your students with marine plankton.
3.
Review the main topics of the PowerPoint presentation with your students: phytoplankton are plant‐like and
have certain adaptations for survival; zooplankton are animal‐like and can exist as meroplankton or
holoplankton; and plankton form the basis of the marine food web. Go over the answers to the student
worksheet.
4.
Distribute a STUDENT WORKSHEET – Lesson 1: Phytoplankton Microscopy Lab to each student.
5.
Divide the students into five groups. Distribute one copy of
SLIDES – Lesson 1: Phytoplankton Microscopy Lab
and two copies of PHYTOPLANKTON ID GUIDE – Lesson 1: Phytoplankton Microscopy Lab to each group.
6.
Tell your students that they will be completing a phytoplankton microscopy lab. Explain that the
SLIDES –
Lesson 1: Phytoplankton Microscopy Lab are phytoplankton images that were taken with a compound
microscope. Compound microscopes have very high magnification, which is essential to view these tiny
phytoplankton. In Lesson 2, dissecting microscopes (which have lower magnification) suffice to study the larger
zooplankton. After a quick introduction to the phytoplankton lab, students should be able to work
independently in their groups.
7.
Have students use the PHYTOPLANKTON ID GUIDE – Lesson 1: Phytoplankton Microscopy Lab to identify the
marine phytoplankton that are found on the various photomicrographs (microscope images) provided in the
SLIDES – Lesson 1: Phytoplankton Microscopy Lab.
8.
Have the students draw the phytoplankton on their STUDENT WORKSHEET – Lesson 1: Phytoplankton
Microscopy Lab.
9.
When students are finished, have them check their answers using the ANSWER KEY – Lesson 1: Phytoplankton
Microscopy Lab.
(
Note: For each slide, only one of each type of phytoplankton is identified on the answer key.)
10.
Encourage the students to check out the Giant Microbe plush toys and the reference books when they are
finished with the lab. Mention that the size of the plush toys is much larger than actual size. The tag on each
plush toy gives its magnification.
Assessment and Clean‐up:
1.
Have students return the
SLIDES – Lesson 1: Phytoplankton Microscopy Lab and the
PHYTOPLANKTON ID
GUIDE – Lesson 1: Phytoplankton Microscopy Lab.
2.
Disconnect the speakers and place them back into the science kit container.
3.
Eject the CD with the PowerPoint presentation (if you have not already), and put it back into the binder.
4.
If you plan to complete additional lessons from this kit, please do not have students complete the post‐survey
(this will be done after Lesson 3) and do not complete the
TEACHER EVALUATION at this time.

5.
If you are not completing additional lessons:
Please have students complete the post‐survey (you will need to make one additional photocopy per
student). As the students are completing the post‐survey, we would be grateful if you would complete
the TEACHER EVALUATION of this kit. All comments, corrections, and suggestions are very welcome. If
you prefer, you can complete the evaluation online (see TEACHER EVALUATION for website address).
Re‐pack the kit. Double check that all the items are included and in their proper place by completing the
SUPPLY CHECKLIST. Please make a note of missing, broken, or damaged items so that they can be
replaced. Please pack the kit so that the materials are stored as they were when you received them.
Mahalo!
