Unicellular organisms are composed of a single cell, unlike multicellular organisms which are made of many cells. This means 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, and Paramecium on the move
The paramecium are the larger protists, the amoeba are the blob-like protists, and the euglena are the smaller unicellular organisms.
We often say that doing something with a machine requires less work. In this design competition, grade 8 students were challenged to help upgrade the gymnasium and physical education programming here at OJCS. Using their knowledge of simple machines, they had to use the design thinking process to design, test, and build a simple machine prototype that enhances our physical education curriculum. Physical education equipment is expensive and gets used up with frequent use. PE is a favourite class for many OJCS students and anything we could do to help upgrade the gymnasium’s physical space or by providing more games and equipment would benefit the school and student Ruach.
EMPATHY – Display an understanding of the problem you are solving by gaining real insight into the needs of the end-users (the OJCS students)
DEFINE – Identify a key area that a product can solve and provide focused research that helps provide a solution to a specific goal (Research of Simple Machines)
IDEATE – brainstorm a variety of solutions to the problem (Documentation of all ideas)
PROTOTYPE – create a model based on rough drafts or blueprints (The physical build!)
TEST – the prototype is shared with others for feedback (Documented feedback)
How did they do it?
Students had to decide what to build, connect our simple machines learning from Science class as part of their research, and create a plan for their prototype. They then had to determine what materials they needed next by searching through Home Depot’s website and placing their order with their teacher. And then, the fun part…
Not only did the grade 8’s successfully link the Science and PE curriculum using the Makerspace to improve the PE department, but it also connected our OJCS students in the process. On Innovation Day they wowed the judges, parents, teachers, and definitely their younger peers, who were enthusiastically asking when they would get the chance to participate in the Simple Machines Project. The grade 8’s should be proud of the legacy they are leaving behind and for starting something new for younger grades to further innovate.
As part of our cross-curricular learning and technology piece of the Science & Technology portion of our class, students will be 3D modelling a Hanukkia in a class-wide STEAM competition. Students are challenged to build candle holder parts of the Hannukah lamp using the online software program, Tinkercad. Each design will creatively incorporate a Jewish hero theme.
All of our class competition information and Tinkercad links will be housed here.
Sizing Guidelines
Your candle holder should be 10cm (100mm) tall with a diameter of 2.5cm (25mm).
Choose a Theme for your Design
Your candle holder design should reflect the theme and can be further explained in your artist’s statement.
There are multiple ways that Jewish individuals have impacted our world. Pick one Jew/group of Jews who demonstrated/demonstrates pride in their Jewish identity and has/have made one of the greatest contributions to our universe. Design your candle holder to reflect this person or group of people. Your artist’s statement should explain your choice and how you think the chosen individual’s/group’s identity as a Jew impacted their contribution to this world.
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.
To prepare for your quiz, go over and practice 1 – 5 (above from lesson 5). A conversion chart, density formula, and sample units will be provided on the quiz.
