Since my eldest daughter did not attend school for some time due to planned hospitalization, we studied the missing topics on our own. Cell structure is one such topic. I remembered that I myself had once done a model of plasticine infusoria shoe that I liked so much that I didn’t even want to give it to school as a homework in biology. And she suggested that her daughter consolidate the study of this topic by making a model of a cell from plasticine.
The daughter brought the cell model to school. It turned out that this was homework, and other children also made a plasticine cage.
How to make a model of a living (animal) cell from plasticine
For the layout, it’s best not to use ordinary clay, crafts from which can be deformed from falling, from high temperature (for example, from summer heat or in direct sunlight), etc., but an elastic soft polymer clay that hardens in air. I wrote about it in more detail in the article "Light self-hardening mass for modeling." We love to sculpt from it, but we have ended it, so this time we had to work with simple plasticine.
There are several ways to make a model of a living animal cell from plasticine (the article used illustrations from the textbook "Biology. Introduction to Biology", Grade 5, authors: A. A. Pleshakov, N. I. Sonin, 2014, artists: P. A. Zhilichkin, A.V. Pryakhin, M.E. Adamov).
The plant cell model can be performed in the same way, focusing on the image of the plant cell from the textbook.
1. The simplest flat model of plasticine cage on cardboard
The easiest way to draw a diagram of the structure of the cell, the production of which will take the least time, is to mold a cell from plasticine in accordance with the image from the textbook.
- Roll from plasticine a long thin sausage and a small ball. Flatten the ball. These are parts depicting the outer membrane and core. 2. Flat model of a living cell made of plasticine
This model is similar to the previous one, but a little more complicated.
- Cut the base of an oval or slightly curved shape from thick glossy cardboard.
- Glue parts depicting the main parts of the cell:
- outer membrane (make it from rolled sausage plasticine)
- core (make it out of a flattened plasticine ball).
- If desired, stick some important organelles of a living cell: mitochondria, lysosomes.
- Signatures can be made directly on cardboard inside the cage.
The same version of the cell model can be further complicated if, at the beginning of the work on a cardboard base, light plasticine is smeared with a thin layer (this will be the cytoplasm).
3. Model of a living cell from plasticine on plastic
Since plasticine after a while leaves greasy stains even on glossy cardboard, the cell model will turn out to be more durable if made on the basis of plastic. When using transparent plastic, you can not cover the base with plasticine. And footnotes or inscriptions made not on the model itself, but on the paper under it, will be clearly visible through a transparent material.
We made a model based on the illustrations from paragraph 5, "Living cells" of the first part of the textbook.
Project executor: Anastasia Viktorovna Nikolaevna, 6th grade student. Project manager: Maria Aleksandrovna Barinova, biology teacher “Plant cell model making” biology project. Denisovskaya secondary school municipal educational institution in the Yasnogorsk district of the Tula region S. Denisovo, 2015-2016.
Purpose and objectives of the project Purpose: study of the plant cell and the construction of its model Tasks: - study of literature, schemes and materials, - manufacture of the cell layout, - design of work, - preparation for the protection of the project.
Cell characteristics A cell is the basic structural and functional unit of an organism.
Work Stages 1. Make Salty Dough
2. Blind the base and organelles of the cell. Stages of work
3. Wait until it dries, and then paint it with acrylic paints. Work stages
4. After the paint has dried, the cell layout is ready. Work stages
5. A model of a living cell from salt dough
You can also make a mock cell of salt dough (in this article, the recipe for salt dough that I use).
- Roll out the salt dough with a rolling pin into a layer about half a centimeter thick.
- Cut the base for the cell layout from it.
- Glue the main parts.
- Leave for a day or two in a warm place to dry.
- Colorize with paints.
DIY models of living (animal and plant) cells
Finally, a small gallery with photos of cell models from the biology cabinet. I apologize for the quality of the photographs - my daughter made them at school by phone, and where the cabinet with the children's works is, there is poor lighting.
And I really liked this work, because I also had the idea of making the model also out of paper, using the technique of volumetric application. The cell model is made of paper using the techniques of drawing, applique and quilling.
