Review of the Microscope

BIOLOGICAL DRAWINGS THE GOOD THE BAD.

Today, we will continue our study of cells using the microscope. In your science notebooks, complete detailed drawings of the cells you observe. Make sure.

Review & Peer Evaluation. 1. Draw what you see, not what you think should be there. 2. Use pencil for diagrams, labels and titles. 3. Use clean-cut lines.

Building a life 4a) Write down the cell parts that both plant and animal cells have. b) Write down the cell parts that plant cells have but animal cells.

Making biological drawings. Biological drawings are used to record the observations made about a specimen The following guidelines should be adhered to.

Scale Bars Scale Bars: images often carry a scale bar which is a horizontal line drawn on the image. The scale bar shows how long the line is in.

Rules of Scientific Diagrams How to Draw Microscopic Images

Rules of Scientific Diagrams Each diagram MUST include: Title Magnification Date Detail Labels Each diagram MUST: Be drawn on a blank paper Be drawn in pencil Be at least 10 cm in diameter Be professional (e.g. lines drawn with rulers)

Why am I SO picky????!

What is this??? putting green? donut? cell? key? landscape? bottle opener? egg?

IMPORTANT NOTE Diagrams must be very descriptive and require many components in order to be properly understood

Diagram Components Title Magnification Date Labels Detail

Diagrams need a….. title The title needs to tell the viewer what the diagram is supposed to be representing

Diagrams need a….. magnification The magnification tells the viewer how many times the object has been “blown up” in size Will be either 40x, 100x, or 400x in this unit

Diagrams need a….. date The date tells the viewer what day the diagram was drawn on

Diagrams need….. labels The diagram requires labels to tell the viewer what each part of the diagram is

Diagrams need.…. detail The diagram needs to be detailed enough to show contours and textures between different parts Do NOT use colour (pencil crayons) when drawing biological drawings

Professional Guidelines Blank paper Drawn in pencil Neat and professional Use Petri Dish or compasses to draw your field of view I WILL NOT ACCEPT ANY DIAGRAM THAT DOES NOT FOLLOW THE PROFESSIONAL GUIDELINES

How would you draw the following image? These are human red blood cells that were viewed at a magnification of one thousand from their actual size. They were observed on November 17, 2014.

Assignment Use a microscope to locate a few cells of the Elodea leaf (prepared slide) Using the guidelines for drawing scientific diagrams, make a diagram of what you see in the microscope Label the following: Cell wall (the outer part of the cell) Chloroplasts (the little green things in the cell) Cytoplasm (the blank space in the cell) DUE:
