CELL PROJECT
Cells are made of an intricate system of parts that work together to perform a variety of essential functionsand they enable body systems to operate correctly. To illustrate the complexity of a cell's parts, create a three dimensional model, of a plant or animal cell, that enlarges the microscopic components of a cell. Both plant cells and animal cells can be transformed into interactive or demonstrative models that identify and explain cell parts.
Cell Model
Purpose: To show Ms. Marley what you have learned about cells in a creative and scientific way.
Method: Make a model of a plant or animal cell with all the organelles.
Assigned: Monday, September 12, 2016
Due Date: Wednesday, September 28, 2016
Directions: Choose one of the three projects listed below OR come up with a creative cell project of your own (please get Ms. Marley's approval for your proposed project by Friday, September 16, 2016. No matter which option you chose, you must attach theCell Description and Function Key (see page 4) to describe each organelle and explain its function.
(1) Plastic Bag Cells
Use plastic bags to create three dimensional interactive cell models. Choose a medium bag that has a secure zipping closure. The bag itself represents the cell membrane or, in the case of a plant cell, the cell wall. Select a variety of objects to represent the cell parts: rubber balls, elastics, string and gummy candies can be used to represent the cell nucleus, ribosomes, endoplasmic reticulum, lysosomes, mitochondria, etc.
Fill the bag with a thick transparent liquid like vegetable oil, baby oil or corn syrup–the liquid represents the cell's cytoplasm. Seal the bag and then place the cell model into an additional plastic bag for extra protection. Fill in the attached key (page 4)to explain the description and function of each organelle. For example, Organelle: nucleus Description: Little blue bouncy ball. Function: The "brain" of the cell. Stores DNA (genetic information).
(2) Gelatin Cells
Gelatin can be used to create a versatile and edible cell model. Clear gelatin prepared in a clear glass bowl serves as a basic model; a flavored gelatin like lemon or lime creates a more colorful model that still offers some visibility. Before the gelatin sets completely, drop objects into the gelatin to represent the relevant cell parts like the nucleus, ribosomes, endoplasmic reticulum, mitochondriaetc. To keep the mold fully edible, choose various kinds of candies and gummy treats to represent cell parts. Once the mold is complete, either leave it in the glass bowl or turn it upside down onto a large plate. Use toothpicks and sticker labels to create flags which identify each cell model part. Take pictures or video of the completed cell model and email to . Fill in the attached key (page 4) to explain the description and function of each organelle. For example, Organelle: nucleus Description: Pink jawbreaker. Function: The "brain" of the cell. Stores DNA (genetic information).
(3) Styrofoam Cells
Styrofoam craft balls (animal cell) or Styrofoam rectangles (plant cell) are an ideal material for making three dimensional cell models because they come in a variety of sizes and can be easily carved and painted. Choose a large styrofoam ball or rectangle, at least 10 inches in diameter, to serve as the basic cell structure. Halve the large ball and secure a smaller ball painted in a different color into the center of one flat side to represent the cell nucleus. Carved and painted pieces of scrap Styrofoam can be used to represent each cell part; secure them to the model with tooth picks and label them with markers or stickers. Additional craft mediums such as yarn, buttons, gems and pipe cleaners can also be used in a styrofoam model. Fill in the attached key (page 4) to explain the description and function of each organelle. For example, Organelle: ribosomes Description: Small blue buttons. Function: Produce proteins.
- If the model is an ANIMAL CELL it must contain the following organelles:
- cell membrane
- nucleus
- vacuoles
- mitochondria
- lysosome
- endoplasmic reticulum
- ribosomes
- cytoplasm
- Golgi apparatus
- If the model is a PLANT CELL it must contain the following organelles:
1.cell membrane
2.nucleus
3.vacuole
4.mitochondria
5.chloroplast
6.endoplasmic reticulum
7.ribosomes
8.cytoplasm
9.cell wall
10.Golgi apparatus
