TOOLS OF TECHNOLOGY – PAINT AND PIXELS
Computer Scientists are scientists that use a design
methodology like the scientific method to collect and analyze data and apply
this to building digital technologies. They
are detail people that look at all variables that impact the output.
This lesson is designed to teach students to look at the
details in a graphic. It uses the
attributes tool in Paint to design the size of a graphic in proportion to the
computer monitor. Students learn about
pixels and resolution.
Image/Attribute, Pencil, Line, Circle and Text Tools in Paint
the canvas size attribute to 400 pixels by 300 pixels
- Draw a
flower or star and your name using pencil tool
- Draw a
flower or a star using the line and circle tool and the text box
width to 400 pixels and height to 300 pixels using a ratio of 4 : 3. Explain this is the proportions of a computer
monitor. Note that graphics look
better on a computer when using a ratio of 4 by 3.
and Contrast measurement units
- Select inches and centimeters buttons and back
width to 1 and height to 1
width to 100 and height to 100 – ask shape and why
with attributes until you understand canvas size in pixels
to concepts taught in math at the appropriate grade level
Application Visual Guide - Fold paper to have a ratio of 4 by 3.
diagonally to make an isosceles triangle
up the extra paper at the bottom and tear off (lick and fold both ways)
paper in ½, in ½ again; fold that paper in ½ and ½ again to make 16
squares when opened.
off the bottom 4 squares.
remains is 12 squares: 4 on one side 3 on the other
this with the 4: 3 computer monitor ratio by holding in front.
Look at coordinate points
pencil tool and move to each corner.
at the coordinate point in the bottom of the window.
pencil around and watch how the location is shown on the grid.
