NOTE Course has FALL and SPRING Semesters 18 Weeks each:
       Fall semester includes micro level biology (genetics, cell bio, ect); Following SPRING Semester includes dissection. 

During the Spring Semester, we will study different types of animals. We'll begin by examining protists and fungi, then move on to plants. After that, we'll study the Animal Kingdom, starting with sponges, then moving on to crustaceans and insects. Later, we'll focus on vertebrates, including fish, amphibians, reptiles, birds, and mammals.

Although the labs mainly involve observing large specimens, it's recommended for students to have their own microscope and slides on hand in case they become curious and want to take a closer look. The course includes a dissection portion where human anatomy is briefly discussed, and some body systems will be studied to help students better comprehend the animals being examined.

The lab session will start with a brief introduction and explanation of the tasks for the day. Students are advised to maintain a lab notebook to keep track of their experiments and observations. The lab provides dissection models of earthworms, crayfish, perch, and frogs. These will used in preparation for dissection or as a dissection alternative.  Students may choose to dissect a live specimen during the lab, but it is not mandatory. Models and videos will be utilized to assist those who opt to conduct a dissection. Students who choose not to dissect a specimen in class will engage in other lab activities instead.

Protist and Fungi 
Week 1: Protozoans, Algae & Pond Life
   -Make observations of micro-organism in water sample
   -View prepared slides of various protozoans and sketch.
Week 2: Molds and Fungi

Otros detalles

Orientación para padres
Microscopes are recommended for this course, glass slides are used. Optional dissection and slide preparations, parental discretion regarding necessary supervision. This class will thoroughly prepare learners who choose to complete a dissection of specimen at home, they will have practiced dissection techniques, have a solid understanding of anatomy allowing them to confidently approach dissection, as well as have access to video guiding them Please confirm class aligns with local standards.
Lista de útiles escolares
Many of the labs will use a compound microscope, full list of supplies will be given upon signing up, and posted in the classroom weekly.

- LAB NOTEBOOK (composition or spiral notebook)

General microscope supplies: 
-microscope
-slide preparation kit - blank slides, cover slips, eye droppers, tweezers, probe
(optional methylene blue, iodine)
-Recommended: "BASIC BIOLOGICAL" slide kit* 
           generally 25 slides, if student has interest in microscopy they may want a larger selection of slides

OPTIONAL SPECIMENS: earth worm, crayfish, perch, frog
basic dissection kit and tray
**NOTE: There are now some formaldehyde free options that have minimal odor

I aim to support your student in building confidence and practical skills through guidance in their studies. Although books have their uses, nothing compares to the benefits of hands-on learning and witnessing the marvels of Biology. My love for Biology stems from its deceptive simplicity, which upon deeper examination reveals a truly astounding complexity.

For a few years, I served as an in-person Biology lab instructor for multiple sections at a local co-op. During my tenure, I guided pupils through experiments, and dissection exercises featuring real specimens such as crayfish, earthworms, perch, and frogs. I also helped students develop their lab techniques, microscopy and taught them how to identify hard-to-spot details.

My area of study is Biology, and I hold a Bachelor of Science degree where I learned about mammallogy, ornithology, ecology, microbiology, histology, aquatic invertebrates. In my co-op lab classes, I gained hands-on experience with microscopes and learned how to create slides rather than just viewing prepared ones. I am now providing microscope classes through Outschool, where students are encouraged to use their compound or digital microscopes during open lab time. I utilize digital cameras to share my own microscope view,  as well as encourage students' to share their microscope view. While I value traditional lab techniques, I also believe that technology can enhance the lab experience when appropriate.

*We will follow study of traditional biology topics that are observable, we will briefly cover topic that are considered theories or are debated. The main focus of class will be observational biology.
