Welcome to the 2021 Innovation Day. A day to celebrate Science here at the OJCS. Find all the schedules and links to live presentations in the graphic below.
Click here to watch all of the videos that the middle school students created for their projects!
All of our Systems in Action unit resources will be posted here and broken down into 3 sub units; Introducing Systems, Getting to Work, and Designing Efficient Systems.
All of our learning, links, and information on Fluids can be found here. All student homework should be saved to your Science: Fluids folder in your google drive.
9.4 – Effects of External Pressure on Fluids (Read, note the definitions of Pressure and Pascal’s Law, complete the ‘Try This’ section at home over a sink or bathtub)
As part of our cross curricular learning and technology piece of the Science & Technology portion of our class, students will be 3D modelling dreidels in a class-wide and world-wide STEAM competition. Students are challenged to build a dreidel using the online software program, tinkercad, that spins and creatively incorporates a Jewish hero theme.
All of our class competition information and tinkercad links will be housed here.
The grade 8 class were fortunate enough to participate in session with Dr. Joanne Tannenbaum about vaccines as part of their unit on Cells. Students were able to learn from home in a shared google meet, and in the classroom as part of our hyflex learning program. They began learning about the differences between red and white blood cells, what their roles are in the body and specifically when they are fighting a virus or other harmful invaders.
Of course, a huge focus of the seminar centered around COVID-19, and the unprecedented development of a potential vaccine. Many of the well-thought out questions from students, both in-class and at home, were about COVID-19, staying safe, the benefits of wearing masks, and where we are currently in the development of a possible vaccine for the virus.
Students learned about the variety of vaccine types available and the difference between live virus vs. non-live virus vaccines, how they augment the body’s immune system at a cellular level by creating antibodies. They even got a bit of history lesson on the first vaccine created 250 years ago for smallpox. OJCS gives a huge thank you to Dr. Joanne Tannenbaum for donating her time…again, to help educate our kids with the scientific facts on this important, and current topic.
Unicellular organisms are composed of a single cell, unlike multicellular organisms that are made of many cells. This means that they each live and carry out all of their life processes as one single cell. Most unicellular organisms are microscopic;
Also called microorganismsor microbes since they are only visible under a microscope.
The single cell is responsible for feeding, digestion, excretion and reproduction.
Some microorganisms make us sick, but without the others we could not survive.
The following are examples of unicellular organisms:
Bacteria
Protists
Some Fungi
Multicellular Organisms Defined:
A tissue, organ or organismthat is made up of many cells is said to be multicellular. Animals, plants, and fungi are multicellular organisms and often, there is specialization of different cells for various functions. In contrast, unicellular, or single-celled organisms are much smaller in size and less complex as they are composed of just one cell that senses its environment, gathers nutrients and reproduces asexually. The following are examples of multicellular organisms: human beings, organs and tissues, plants, animals, birds and insects.
~Generally speaking, we can say that unicellular and multicellular organisms are alike in that they exhibit all the functions of life, such as metabolism and reproduction, they contain DNA and RNA, they can exhibit a wide range of lifestyles, and they are essential to almost every ecosystem that we currently know of.
Amoeba, Euglena, Paramecium on the move
The paramecium are the larger protists, amoeba are the blob-like protists, and euglena are the smaller unicellular organisms.
Here are some helpful tips as you expand on your web literacy, research, and digital citizenship skills. Feel free to download a copy and add it to the Research folder located in your Science folder to refer back to it when needed. Review Sheet found below.
